I. Before You Begin

1. Some memory cards simply will not let you edit them in the way we are about to, so you may need to do this procedure and if it doesn’t work, try a new memory card. 2GB Kingston SD card DOES work for sure so up to you if you want to just buy one of those before beginning.

2. YOU WILL NEED AN SD ADAPTER! This can be a MicroSD to USB that allows you to plug the SD card into your computer’s USB port OR a MicroSD to SD adapter if you have a SD port on your computer.

II. Setup ADB

1. Follow these instructions (with video) to setup ADB for your phone, then come back to this procedure to continue.

How To Setup ADB

III. Create a Goldcard

1. Put the memory card you want to use for the GoldCard into your phone.

2. With the memory card in your phone, click on Settings, SD and Phone storage, then click Unmount SD card. Once it unmounts, click Format SD card. (Please keep in mind that some memory cards don’t work, and this will erase all data on your SD Card so back all the data up first to your computer)

3. On the Phone, goto Settings, Applications, Development and then make sure USB Debugging is checked.

4. *Make sure you have installed the SDK and Fastboot correctly from Section I!!!
Plug the phone into the computer and then open the Command Prompt (goto the start menu and type in cmd in the search box). Then type the following with hitting enter at the end of each line.

adb devices

(wait for it to show a serial number underneath, if it doesn’t then reinstall the drivers from section I).
Then type:

adb shell
cat /sys/class/mmc_host/mmc1/mmc1:*/cid      (There is no spaces in this line EXCEPT right after the word cat in the beginning, make sure to put that space in)

5. A code will display, write the code down      (MAKE SURE TO WRITE IT DOWN EXACTLY!)

6. Now with the code written down, simply write it backwards (it must be reversed, so if the code is 123456789, slowly write it backwards and make sure not to make a mistake so it becomes 987654321 then continue to the next step).

7. Now, on your computer, goto http://psas.revskills.de/?q=goldcard and enter your email in the appropriate field and for CID enter the reversed CID you just copied down BUT REPLACE THE FIRST 2 DIGITS WITH 2 ZEROS! (i.e. 12345678910 becomes 00345678910). *Thanks to Viper for providing these Goldcards for FREE!

8. Click continue and then you will receive your goldcard.img via email. Once it arrives save it to your computer.

9. Now, goto http://download.cnet.com/HxD-Hex-Editor/3000-2352-10891068.html?part=dl-HxDHexEdi&subj=uo&tag=button to download the HxD Hex Editor. Save it and install it to your computer.

10. Take your SD card out of your phone and put it into the SD adapter it came with. Then put that into your computer so it shows up on your computer as Removable Disk.

11. Open the Hex Editor (Run as Administrator if one Vista or Windows 7) and click on the Extra tab, then click on Open Disk. Under Physical Disk select Removable Disk (your SD card you just put into the computer). Make sure to UNcheck “Open as ReadOnly”. Click OK.

12. Goto the Extra tab again and click Open Disk Image. Open up the goldcard.img that you saved from your email. You should now have two tabs, one is the SD card (Removable Disk) and the other is the goldcard.img
Press OK when prompted for Sector Size 512 (Hard Disks/Floppy Disks).

13. Click on the Goldcard.img tab and click on the Edit tab and click Select All. Then click on the Edit tab again and click Copy.

14. Click on the Removable Disk tab (Your SD Card) and select offset 00000000 to 00000170 then click on the Edit tab and click Paste Write.

15. Click on File then click Save.

16. Close the Hex Editor.

17. Test what we’ve done:

Take out the memory card from the computer, then put it back in.
Try to open the memory card on the computer (Removable Disk), if it lets you, you are all set. If it asks/tells you to reformat the card, then try steps 13 – 19 again. If it gives you the same error again, then try a different memory card (Erlern said it didn’t work for him until he finally went and bought a Kingston 2GB card, then it worked on that card).

18. You can now use this goldcard to root phones that were previously unrootable!

Reported Issues:

Issue: I get no such directory or file when I type:

cat /sys/class/mmc_host/mmc1/mmc1:*/cid

Solution: Try to type this instead (replace the 1’s after mmc with zeros):

cat /sys/class/mmc_host/mmc0/mmc0:*/cid

Issue: Having difficulty with the cat command…


“Plug your phone into your computer with the going to be gold card
Go to my computer
Make sure you mount your phone to your computer
Right click after mounted FORMAT on your drive NOT IN THE SETTINGS>FORMAT MODE (trust me)
dont do quick format let it run its course
After it has completed formatting come back to the steps starting at step number 4.”

Thanks to MBerue for this solution! Hope it helps people!

  • chris

    what is a goldcard

    • Shoeb Eee

      CID is a id of a microSD card. Is it okay? If yes, what is the relation between this CID and making a branded phone into unbrand using gold card?

  • bishar

    Chris loooool that’s Good Question, Theunlockr, my friend, I don’t even understand what’s the Gold Card?

    • Bishar and Chris,

      A goldcard is a special SD card that can bypass a phone’s security checks (in a nutshell lol). So you can make a goldcard and then put the Sappimg.nbh file on it that would not normally load and it will load because of the goldcard.
      We usually use it to flash the wrong phones ROM onto a phone so it can be rooted then root it and load back the original ROM.

      Its going to be used big time in the How To Root the MyTouch 1.2 that I’m working on.

      • roger

        what do i do after i created the gold card im lost please help

      • Hey Unlockr, thnx for the tutorial, I know now how to create a goldcard, now it might be a little foolish to ask this question, I actually wanted to flash my upgraded htc Wildfire 2.2 from Stock HTC wildfire rom 2.2 and not to forget mine was unlocked while i purchased that means i can use sim from other carriers also. I wanted to root my phone I tried using Z4root and Superoneclick but both didn’t work for me, I thought it might be because of that I upfraded to 2.2 as generaly people say 2.2 is hard to root, now thinking that I want to flash that 2.2 which I upgraded to 2.1 again, I even downloaded the stock rom for my phone from shipped-roms site now inorder for me to flash it do I need the gold card??? and if I need after having one how can I flash it ??? If I don’t need goldcard to flash that how can I do that ??? i’ve the RUU exe file ?? please reply I’d really appreciate, I’m pulling out my hairs and I’m afraid I’d go bald lol :P, jokes apart, help will be greatly appreciated 🙂

      • Paul

        unlockr, I don’t mean to question you as I’m sure you’re 10 times smarter on these matters than I am, but how can that be? The gold card image was created based on this individual phone’s CID. If we were to try to use it on a different phone, would it really work even if it’s on a different phone with a different CID?

        • Paul,

          Ha always learning.
          So you would think that and that would make sense but I’ve used the same goldcard on multiple phones without issue (even seen sites sell goldcards for use on other phones etc). So who knows?

          • Paul

            Interesting. Unexpected, but definately very good to know! Thanks.

    Hi Unlockr,
    I have made a Goldcard, perhaps successfully – windows gives me no errors. However, when i put a sappimg.zip on the phone hboot does not see it. (i have an htc magic; no image or wrong image – is the error)
    Does that mean that the goldcard failed or something else is wrong?


    • Eyegor,

      No image doesn’t mean the goldcard isnt working, it means the img is not seen by the phone. So either it is not on the root of the SD card (NOT in any folders, just on the sd card), or it is named wrong (perhaps .zip.zip accidentally).
      Good luck!

  • Eyegor

    Thank you very much for your quick response!
    I shall test is with my Tattoo!

    Great guide!

  • bevins68

    I have tried the process with 4 different SD cards (1gb/2gb kingston/2gb sandisk/8GB class 4 that came with the mytouch.) Every time I put the card back into the PC after the HXD operations I get ‘this card needs to be formatted’

    Surely with someone confirming the 8GB one that came with the MyTouch as working I am missing a step? Please advise.

    Thanks in advance.

  • bevins68

    I also do not have the option in HXD to open the SD card as a Physical Disk as it says in the instructions. The only way for me to open it is under Logical Disk

  • bevins68

    Please disregard my last 2 posts. I am an idiot.

    Thanks for the guide 🙂

    • Bevins68,

      Lol. No problem. Would you mind posting what you did wrong so others can avoid it?

  • Ash

    I followed the procedure noted above, the minisd keeps saying to format when testing…I used Kingston SD…would a mytouch with 1.6 firware affect the process.

    • Ash,

      It could be the card, some do not work for the goldcard procedure. Try to use it in the phone and see if it works as a gold card, if not then use a different SD.

  • Ash

    In step #7 you ask to insert the revesed serial we did in step #6 and change the 1st 2 numbers to 00, however Step #6 already places the code with two zeros…do I change the zeros to zeros again…??? or there is other charachters I need to hcange to Zeros. I am lost

    • Ash,

      The guys reverse string app sometimes puts the zeros in for you. So long as the first 2 characters are zeros you are fine and just continue.

  • Jonesy

    Just wanted to say thanks to TheUnlockr. I was able to get the goldcard to work on my T-mobile G2 without the need for a micro-sd adapter, I did it all through mounting the SD card whilst it was still in the phone. I was using the card that came with the phone (2gb sandisk) and am running Windows 7. Now running MoDaCo 3.2 and am really impressed. Battery life at least 3 times better and the same for signal. Thanks and keep up the good work!

  • Pho

    Hey Hey Hey!!!

    After i created this “GOLDCARD” can the GOLDCARD be used as a normal SD card?

  • Joe

    Instead of selecting 00000000 to 00000170, go to 00000000 and paste write and it overwrites everything to 00000170.

    I think people are selecting and overwriting the wrong area causing the gold card to fail.

    You can make these in a hero with the stock card.

    This is a piece of cake.

      Yo Joe!
      You’re a freakin’ genius! and theunlockr, lol! That’s what did it for me was selecting 00 instead of 170!

    so… after many failed attempts, i’ll try once more.

    i notice when i paste the img onto the card, it moves the existing info on the card lower, below line 170. i’ve been actually ‘inserting’, not overwriting that original info.

    i realized in the middle of the night that i should be overwriting the info on the card, not just pasting the img at line 00.

    i haven’t tested this yet, and won’t have a chance for a few days.

    but am i correct about deleting the existing info before i paste the new img?

A little help would great.

  • MisterEd

    Mr Unlockr,
    Methinks you have a typo in step 7. Step 6 generates the code with the digit reverser and it adds the leading 2 zeroes.

    In step 7 you say to add 2 leading zeroes which was already done in step 6 automatically.

    This might lead to some corn-fusion. 🙂

    • MisterEd,

      Thanks, but I put it there because people were saying the code didn’t have 2 zeros a long time ago (think the creator of that page has fixed it since then). But didnt see any harm in leaving it, your going to change 2 zeros to 2 zeros, right?

    • Nenad,

      Make sure your memory card is not mounted.

  • Kay

    I accidentally overwrote the contents of my hard disk instead of the SD card at step 11. Naturally my PC failed to boot after that. So I put in my Windows XP CD and went to Recovery mode and rebuilt the MBR using the ‘fixmbr’ command. My PC now boots normally and hopefully it won’t have any detrimental effects.

  • Dana

    i know this question may sound dumb,but can you use a goldcard as a regualar SD card after changing it?

  • Jayson

    I tried this guide on two cards, successfully creating two different gold cards. At least I think I was successful. Both cards load up in Windows fine, and opening them both back up with the hex editor shows that the goldcard image is still in its mbr. So I wonder why I still can’t root my myTouch with perfect SPL 1.33.0007? I’ve tried all the different sappimg.zip and .nbh’s that I could find floating around on the internet, and all I get is a Model ID incorrect error…

    Going back to my goldcards, I found that sending the exact same reversed cid (original cid copied from an adb shell), psas sends me slightly different goldcard.img’s. I have attached these img’s in a thread over at xda-forums: http://forum.xda-developers.com/showthread.php?p=6402002#post6402002. Look for me, javon27.

  • Kay

    On my card the mounted directory was mmc0 instead of mmc1. So if you are having the No such file or directory error, try:
    cat /sys/class/mmc_host/mmc0/mmc0:*/cid

    This worked for me and now I have a rooted Legend. =)

    Thanks Unlockr for a great guide. Maybe you can add a footnote to this step.

    The guide on how to make the GoldCard is awesome and very insightful but I’m having a slight problem. Everytime I try placing the sappimg.zip file on the root of my SD Card and go into FASTBOOT, it keeps saying “Model ID WRONG” etc…I’ve attempted to create the GoldCard quite a few times using a SanDisk 8GB (that came with the myTouch 1.2) and a Kingston 8GB. Do you think using an 8GB SD Card could be the problem?

    Hi unlockr and congrats on an excellent and informative site.

    I am (pretty) sure I have dodged all the obvious pitfalls but am still having problems creating a goldcard to work with my 32b Magic 1.33.0007.

    Firstly the one click method did not work on my spl so a goldcard seems to be my only route to rooted nirvana.

    I have followed all the points to the tee (3 times!) and keep getting the same error I am using a kingston 2GB I have got the reverse CID and been emailed my goldcard.img (3 times – all the same) when I copy the offset 00000000 to 00000170 from the img to my sd card and save it shows as being identical to the img file (from offset 00000000 to 00000170) I can open and browse it on the PC fine.

    When I copy sappimg.zip onto it to try and flash the phone returns the same error (wrong image etc) each time. The weird bit is that when I put that kingston sd card back into HxD to check everything there are differences in offset 00000000 to 00000170 – only a couple of charecters wrong, but wrong nonetheless. I am assumming this is why I cannot load the sappimg.zip but I cannot find out why my goldcard will not stay as I saved it even when using a proven card.

    It is now 6am and I started this at 11pm yesterday so I am in desperate need of any help!


    • Max

      Clearly, it’s 12:51 not 6am lol

  • Puresp

    To Unlockr,

    I’ve tried your method to create the goldcard at least 20 times already, still no luck. Like, literally.. I’ve gone through the entire process over 20 times. I even bought a new 2G Kingston MicroSD card since maybe I thought the default card wasn’t capable.. Still didn’t work?

    I followed your instructions to the tee and still no luck? I have W7, but I did all the steps to installing the ADB anyway. Please help?

    Also, I previously wasn’t aware of the difference and thought my phone was a Magic 32b, so I STARTED to download the neccesary files and I changed the SDK around a bit from a guide on a cyanogen guide, would that have messed up my install?

    Well, i guess not…
    It all goes well, but when I save with the hex editor after pasting the image in, and reinsert the altered sdcard into my phone it says it is damaged, and I can’t open it in explorer.
    Not sure if it is the phone or the sdcard causing this of course (using a sandisk 2GB mirco sdcard), I guess I’ll have to get an adapter or reader somewhere to make sure.

  • Harry

    Thanks for this tutorial…
    With it I was able to create myself a gold card.
    It took sometime due to Windows7 but still I made it.
    Thanks again!!

    thanks a lot for this tutorial.
    i have successful created a goldcard with this guideline. and updated new ROM which is requires a goldcard.
    but.. in the middle of my exploration, i did something stupid which is required me to update a new ROM again. when i tried to update, i get Customer ID. which is goldcard problem.
    so.. does it means i have to crate goldcard once again? or get a new microSD?

  • Branden09

    hello Unlockr.

    i have followed your steps and even read through basically every comment for possible alternitive solutions.
    but this is frustrating me.
    i have tried replacing both the ‘1’s with zeros in the string: $ cat/sys/class/mmc_host/mmc1/mmc1:*/cid
    $ cat/sys/class/mmc_host/mmc0/mmc0:*/cid

    but it still says “not found”

    i have properly setup everything, because it shows my device as connected to adb when i type:

    cd AndroidSDK\tools\
    adb devies

    would it be the sd card? or possibly something else?
    any soultions?
    thanks for your time.

  • Branden09

    please disregard the previous comment. i have fixed the problem, though i am trying to get the goldcard to actually work right now. im able to put it back in the computer without it saying “reformat” or anything else. but when putting the goldcard into the phone with the sappimg.zip file and successfully access the bottloader, it says: *wrong model id.

    ive tried multiple different sd cards, latest one being a 2gb kingston and it still wants me to format when i re insert it…
    not sure what i can do now? since this is supposedly the only option i have?

  • Mark

    For people who has the “No such file or directory” error…. Please beware that you will need to insert your memory card…. The cat command reads value based on the microSD card that you inserted. Therefore each different card will give you a different initial value to work with…

  • jean

    Same problem as Chris. I first tried to create a goldcard with my original SanDisk card (2gb) and then with a new Kingston (4gb), but both failed. When I insert the SD card back int my G1 it says “SD card damaged” and I can only format it.

    Any help on this ?

    is there a way to undo this? it’s just it didn’t work but I can’t remember what the codes before I ‘paste wrote’ it were… help?

    Can the code contain a ‘ß’ (spaß) character? I have something that looks similar to an 8 and a B and can only assume it’s a ß.

  • James

    On second thoughts maybe it’s just an 8.. They seem to differ slightly.

    I don’t have an sc adapter but have noticed on the desire that you can set it up as a disk drive. Maybe I won’t need one after all?

It says “Incorrect Model ID.” I’ve read elsewhere that this means that the goldcard wasn’t prepared correctly, but I’ve done it several times, and with my new sdcard, windows is able to read it just fine.
    So is it possible to screw up the goldcard-making process and still be able to pass the “test” of reading it in Windows? I’m going nuts here…

  • tony

    Hey unlockr

    Ok so im stuck at the cat/sys/… commands. what i want to know is, if you can use the gold card again and again and even on different phones, does that mean its not specific to any particular phone? and if so cant someone just post the image to be downloaded for everyone else?

    Everyone else

    Any help would be greatly appreciated because i have tried replacing the 1’s in the command with 0’s and still am stuck.


    • Tony,

      To answer your “can someone post the image” question. It is not phone specific, but it IS memory card specific. So regardless of what phone the memory card is in it will work but you need the CID of that memory card to make the goldcard in the first place.

  • Chuy

    For those who have the error “no such file or directory” when typing:

    Hi, I was having the “cat/sys/class/mmc_host/mmc1/mmc1:*/cid: not found” error, till I realized there is a space between “cat” and “/”. Please, put a note in the instructions, or change the font, so people notice it. Thanks.

  • For anyone that is having issues with section III. step 4. using the shell and receiving the “No such file or directory” message. I will assume that you have already read through the rest of the threads and don’t have your SD card mounted, verified that there is a space between the command and the location of the file and have already tried changing your 1’s to 0’s.

    I had a serious “Doh!, @#$%” *smack forehead, moment when I navigated to the directory …/mmc1/ to find the I had been putting a period(.) where there shoud have been a colon (:)…should have been “cat /sys/class/mmc_host/mmc1/mmc1:*/cid” I was typing “cat /sys/class/mmc_host/mmc1/mmc1.*/cid” simply because the asterisk (*) masked the top part of the colon.

    After trying for hours of disconnecting my phone and restarting my system and other forms of trouble shooting did decide to navigate to the directory where the colon became very apparent under font of the DOS prompt.

    In my case it was mmc1:1234
    so my cid file was located in the directory
    and typing in this command would have worked
    cat /sys/class/mmc_host/mmc1/mmc1:1234/cid
    But the original command would have also work if not for my own oversight of putting a period in place of a colon.

    Hope this helps someone.

    also for those who wanna make one without having to mess with the sd inside the phone, you can format from windows to fat32 then while your phones in recovery remove your sd and install the sd you wanna make a goldcard. enable usb to make sure its readable and then disable it.
    from your windows command do as stated and you can get your sd serial that way also providing youve folowed directions and commands.
    after youve gotten it close command screen, remove sd, place your regular sd back in your phone and turn it on.
    from there you can follow instructions from the sd reader.
    done with a G1

    The whole process is somewhat easier if you use the “goldcard helper” application from the Android market. This automatically obtains the card’s CID and reverses it – so you can directly paste this information in the PSAS website.

    each time the card is fine, I requested the goldcard.img with the reversed id, and made sure the first two chars are 00.

    I copied the goldcard.img to the 000 – 170 on the removeable disk. Test the card seems to work fine, and then I copy the sappimg.zip and test.. all is fine.

    The problem arises when I run the RUU. It recognizes my phone and the ROM that’s running on it. The phone restarts and then the RUU starts updating the signature.

    Then I get the error:

    The ROM Update Utility cannot open the requested files or the files are damaged. The RUU cannot continue with the update.

    Please get a complete RUU package and try again”

    Is gold card really so unnecessary?
    I mean, can I simply put custom recovery via fastboot and flash custom rom after?

    • Ikec,

      Depends on the phone you are using. Some REQUIRE a goldcard because they block you flashing anything via fastboot etc so we use the goldcard to flash an older/different official ROM on the phone (which it wouldn’t let you do without the goldcard) and then we are able to flash fastboot etc after.

    It says in the first post to 2. With the memory card in your phone, click on Settings, SD and Phone storage, then click Unmount SD card. Once it unmounts, click Format SD card. (Please keep in mind that some memory cards don’t work, and this will erase all data on your SD Card so back all the data up first to your computer)

    I have figured out easier way if people are having errors with cat sys mode.

    Plug your phone into your computer with the going to be gold card
    Go to my computer
    Make sure you mount your phone to your computer
    Right click after mounted FORMAT on your drive NOT IN THE SETTINGS>FORMAT MODE (trust me)
    dont do quick format let it run its course
    After it has completed formatting come back to the steps starting at step number 4. *Make sure you have installed the SDK and Fastboot correctly from Section I!!!
    Plug the phone into the computer and then open the Command Prompt (goto the start menu and type in cmd in the search box). Then type the following with hitting enter at the end of each line.

    I have a desire that, after flashing with a Froyo gets stuck on the green HTC logo after start.
    I would like to create a goldcard, but i cannot use the “adb shell cat /sys/class/mmc_host/mmc1/mmc1:*/cid” command since adb devices returns no devices (after booting in HBOOT). If i boot the desire in fastboot however, i CAN use the fastboot devices and that returns a device.
    I can get a lot of parameters from the fastboot command:

    C:\AndroidSDK\tools>fastboot getvar all

    Is there ANY way i can get the info to create a goldcard (without using the adb command?

    I wanna buy a new card just to turn into a goldcard and keep but how large a memory card would i need for this, is 1gb enough?

  • Sean

    Basically I’ve gone through all the steps and can’t get the Gold Card to create. I’ve tested it with a 8gb Kingston, 1gb Patriot, 1gb Sandisk. All of them require I reformat after I save. Triple checked the CID’s on all cards before I copied them over and each time it already replaced the 00’s for me. What are the odds that 3 cards won’t work? I’m racking my brain here.

    • Sean,

      Make sure you are editing the thing as Physical Disk when it asks and not Logical Disk. Also make sure you open the Hex Editor AS ADMINISTRATOR or it won’t work.

    before i want to root my mytouch fender, i had some questions?

    Will this work with a class 6 sd card in general(specifically from TEAM, http://cgi.ebay.com/Team-Class6-microSD-micro-SD-SDHC-TF-Memory-Card-8GB-8G-/300396474564?pt=PCC_Drives_Storage_Internal&hash=item45f10670c4#ht_2753wt_932)?

    Do i need a class 6 sd card to make the jachero rom fast?

    what type of sd card (class and gig) is required for the jachero rom?


    • Sandman,

      First off, for a Goldcard it doesnt matter the class of the card. The goldcard is just to load files with bypassing the version checking etc.

      For JACHero ROMs etc you are referring to using swap and ext. Those things would run much better with a class 6 card than any other card (since class 6 means it can transfer data at 6Mbps instead of class 4, 4mbps, and class 2, 2mbps).
      I’d get a popular name brand version to be safe.
      You can use any class but class 6 will be best (not for the goldcard, but for using a Hero ROM).

      • Sandman

        THANK YOU!!
        and btw, is transcend a good company?
        thanks again!

    hey just to let people know who are using tethering, you must disable tethering in order for this to work. i was stuck for a long time when i would put “cat ?sys/class/mmc_host/mmc1/mmc1:*/cid” and it would say “no such file or directory”. do your downloads set up the HxD then disable tethering and follow the procedure and you should be able to get everything working right. NOTE, and for people with xp (im not sure bout other systems like windows7 or vista or etc.), after you do the procedure tethering will not work so you will have to press control+alt+delete at the same time, then open up task manager, click on adb just once, then click on end task and tethering should work again. you will have to do that every time u use the “cmd” for your phone to get tethering to work again…….hey unlockr you outta add this note to every troubleshooting that deals with the “cmd” and goldcard. it took me a week to figure out what i was doing wrong till i finally turned of tethering and it worked and i did two cards in under ten minutes.

    -This seems to solve the damaged SD card error. PLEASE add this to the article courtesy of 'TheCurryFace'

    When reformatting the card, Windows will place the DOS boot record at sector 0 and the MBR after the DOS boot record. The SD Card user module is not capable of working when the DOS boot record is placed in Sector-0.

    To fix this issue, follow the steps below.

    (1) Download Panasonics SDFormatter V2.0 (free utility)

    (2) Insert SD card into Windows PC

    (3) Format the SD card with the Panasonic utility, SDFormatter V2.0, using the following options.
    – Format Type: Quick
    – Format Size Adjustment: Off

    (4) Eject the SD Card (**This is an Important Step**)

    (5) Re-insert the SD card

    (6) Format the SD card using Windows Explorer
    – Right click on the SD card and select format
    – Set file system to FAT
    – Do not select Quick Format

    (7) Eject the SD Card

    (8) NOW You can proceed through the steps as normal and hex edit using the PSAS image without fear of the dialog box "Please format this drive". =D
    In the above method, the Panasonic SDFormatter utility places the MBR in Sector-0 and Dos Boot Record following the MBR. With both the boot records intact, Windows will not alter the position of the boot records and will only initialize the FAT tables during formatting.

    then i have an error: file not found

    In some guides i found to use another number in the path as

    cat /sys/class/mmc_host/mmc0/mmc0:*/cid

    cat /sys/class/mmc_host/mmc2/mmc2:*/cid

    This 2 commands give me 2 different number, can i use them to generate the gold card?
    What does it mean mmc1 / mmc0 or mmc2 ?


    • CosmoS

      I got the same problem

      No such file or directory…

  • After few hours of fighting with HTC i finally downgraded it.
    First if You still have problem with some steps. Use HTC Sync instead of CHARGE MODE ONLY.
    If Bootloader don’t find files to downgrade, format Your SD card in Windows using FAT32 mode. Don’t format Your card using the phone after.
    MOST IMPORTANT – step 6 is wrong completly
    if your mmc0 or mmc2 number looks like this
    correct ‘reversed’ number is
    00544d5107943247039c7d22bd002653 because 02 must be replaced by 00
    good luck

    • Bryanskinner1980

      Thx you are a hero!!!!!

    • That doesn’t make sense. Where are you getting the string of numbers? The ones you typed out are not reversed, and you didn’t specify how you came up with that string of numbers. Unsure about this. Please advise. Thanks. 🙂

      • Francesco Montalto

        the mmc# returns a string of hex digits (simply put one hex character is two ascii characters long). In order to reverse this you would use two characters at a time. Therefore for example A2HB reversed would be HBA2 and A2HBG117 reveresed would be 17G1HBA2. Now just follow this pattern and you’ll see it works. That is if anyone is still having issues.

    To those who still receive “28002 not allow”, the method of reversing the code here is not corret.
    You need to reverse IN PAIRS, for example:

    Pro tip:  go to android market, and DL “gold card helper”  its free and pulls the CID, reverses it and has a link under menu button to enter it into the website that generates the goldcard.img file.

    Also, I overlooked this.  When opening the SD card in the Hex Editor, Notice this guide says open the PHYSICAL DISK in bold…  repeatedly editing the LOGICAL drive was frustrating for me.  🙂

    No need to go and buy a USB sd card. It does work by leaving your memory card in the phone.
    1. Have the cable connected to the phone
    2. Unmount the memory card using the phone
    3. Format the memory card using the phone.
    4. re-mount the memory card using the phone
    5. It will show up on the computer as a Removable drive. (if not unplug USB and plug in again”
    6. I re-formatted the drive using the computer to do the format (Not sure this was needed)

    When trying to obtain the CID of the phone using the AndroidSDK. Have notepad open and cut and paste between the black “cmd” box and notepad. The “edit – mark – copy” facility is available by clicking on the the top left corner of the black “cmd” box.

    When using HexEdit.
    1. Must open HexEdit as administrator (Easy to forget this)
    2. Open the “disk” and not the “file” “Removable drive”. Once “Removable Drive” selected “un-click” the “read only” focus. Another one I kept forgetting to do.

    Apart from that….Bob’s your uncle!

    The faster way to get ur CID is coping ur sdk to ur sd card and download terminal from the market and use cat /sys/class/mmc_host/mmc0/mmc0:*/cid and u will get ur sd card number. write it down! thats wat i did and it worked for me now i got my gold card very easy..

  • Hoon Jung

    you should clarify how to reverse the cid numbers cuz it was hard to figure out

    Goldcard generetor says “error: no MMC card found” …does this mean i can skip the goldcard step?

  • Anonymous

    Good tutorial so far for me, but is there any other way to get a goldcard than the psas.revskills.de site? It says “page not found.” Any help would be greatly appreciated, thanks.

  • Andrew Kumnick

    Having trouble, the PSAS site is reading with an error of the CID being to short ???

    I think I’m doing something wrong? I can’t even get past adb devices. . . also on the sdk manager log it keeps saying access denied and skipping things I select to download?

    Another way of doing it in *nixes is using dd issuing the following command  
    dd if=goldcard.img of=/dev/sd· bs=1 count=368 conv=notrunc

    Where · is your SD card.

    ·· Be careful to avoid wiping your hard drive 🙂 ··

  • Daithi Cork

    Use http://hexrev.soaa.me/ to properly reverse the CID!

    Hi all, I hope someone can help as I have noticed that it’s been a while since someone wrote on here.
    I’m trying to get my goldcard img, but it don’t ask for your email so where does it go? When I put my CID code in then the code as you see at the bottom click Download Goldcard it vanishes to “Internet Explorer cannot display the webpage” but if I refresh the page it states “The goldcard image has been downloaded !” but to where? I even given some money  (Donated) for the codes but still nothing! I even checked all my mail accounts and nothing so what is wrong? I can’t even find the join link so I can put my email in but still nothing. Have I done something wrong? I’m using W7 if that is any help.

  • John Jones

    Don’t Worry about it I did it on another W7 pc and it worked. so thanks for looking. 🙂

  •  When I type adb devices in Candroid-sdktools, I get this message ‘adb’ is not recognized as an internal or external command, operable program or batch file. HELP!

    • PENG

      Use candroid-sdkplatform-tools

      Remember to put the “fastboot.exe” in the platform-tools folder then.
