How To: Activate the G1 Without a Data Plan

So by request, here is how to activate a G1 without a data plan or even a SIM card 🙂 (If you have a request for us to do a How To Video on, visit here).

Thanks to all the people who sent this request in!
Thanks to JesusFreke for the procedure!


If you are using the carrier the phone is locked to (Rogers in Canada, or T-Mobile in the US, etc.):

1.The easiest way to do this if you are in the US, is to get a friend to put his T-Mobile SIM with a data plan into your phone, activate it, then put your SIM in after.


2.Just add the Data plan to your T-Mobile SIM for the day and then remove it once you have activated the phone. (This will literally cost $1, $30 data plan divided by 30 days in a month times the amount of days you used the data plan equals $1).

If you are using a company that the phone was not locked to (in other words you unlocked the phone with an unlock code or bought it unlocked from somewhere):

1. Just put in whatever SIM you are using, then on the activation screen, hit Menu then click on APN. Click add APN and put your company’s internet settings in (ask your provider for these settings). Then add the data plan to your account for the day and remove it after you have activated the phone OR get a friend with a data plan to activate it for you.

The following procedure can be used if none of the above are available to you…

I. Getting Back to RC29

1. This procedure requires you to be on an old version of Android (RC29 aka Android 1.0) so you must use our unroot procedure first and get to RC29, DO NOT DO THE STEP THAT TAKES YOU BACK TO CUPCAKE, skip it and come back to here once you are on RC29.

How To Get Back to RC29

2. You also need a WiFi connection to do this procedure.

II. Setting Up ADB

1. After you are back to RC29, follow our How To Setup ADB procedure EXACTLY as it is written. Once you are able to see your phone’s serial number after typing ADB devices in the command prompt, then come back to this procedure.

IIIa. Activating the Phone Over WiFi WITHOUT a SIM.

1. Borrow someone’s SIM card then procedure to Section IIIb.

IIIb. Activating the Phone Over WiFi WITH a SIM but No Data Plan.

1. Turn on the phone, you will get a Touch Here to Begin Screen.

2. Open the phone’s keyboard and hit enter once then type the following on the phone’s keyboard:

setprop persist.service.adb.enable 1

3. Then hit enter.

4. Hit enter AGAIN and type the following on the phone’s keyboard:


5. Then hit enter.

6. With the phone still plugged in and the command prompt still up on your computer screen from the ADB process, type the following in the command prompt on your computer with hitting an enter at the end of each line:

cd c:\AndroidSDK\Tools\
adb devices

*this should bring up a serial number if your phone is connected, if not then redo the setup ADB process.

7. Now, in command prompt on your computer, type the following with hitting enter at the end of each line:

adb shell
am start -a android.intent.action.MAIN -n

8. On your phone should pop up the Android Settings screen, you can now choose a Wifi network to connect to then hit back and finish the activation process over Wifi. Enjoy!

    Thank you , thank you Unlockr. More easy it not can be.

  2. Shatterv2 says:

    Surprised there are videos still being made for the g1 aka “iphone killer”.

  3. wallingsworth says:

    ?Will this work for the Mytouch3G? What are the benefits to doing this

    • TheUnlockr says:


      No since you need a keyboard for part of the procedure. The benefits are for people that do not have a data plan or that are using a Non T-Mobile SIM etc.

  4. mike says:

    Will this work on the mt3g? can we upgrade. to 1.6 after activating?

  5. daze says:

    what’s the purpose to activating the G1 someone please e[S]plain to me :{D

  6. JKshowman says:

    really don’t you just have to:
    1. go to rc29
    2. on “click android” part setprop persist.service.adb.enable 1
    3. on adb: am start -a android.intent.action.MAIN -n


  7. dav123 says:

    hey i got to step 9 ans entered the su and my computer keepon saying permission denied what do you think i did wrong

  8. Wallingsworth says:

    I have a rooted Mytouch can I use a at&t sim if i wanted to? does this give G1 users free data through wifi?

  9. Wallingsworth says:

    @theunlockr is it possible to unlock the MT3G?

  10. Wallingsworth says:

    i forgot to mention i started using google voice so i am wondering if it will still work if i don’t have a SIM? would my mt3g have to be unlocked or would i still be able to use wifi for google voice without the SIM?

    • TheUnlockr says:


      Google Voice SHOULD work with any internet connection technically once they make it entirely voip, but I believe right now it needs a GSM connection to operate. But give it a try, take out the SIM connect to Wifi and see if it works.

  11. JKshowman says:

    i know im not unlockr but:

    yes all that should work, not going to go into details, but yeah without sim, wifi will will definitely work, and therefore google voice 🙂

  12. tone says:

    i can get pass step 8 on part IIIa.

    i get the following error:

    ‘chmod’ is not recognized as an internal or external command…

  13. tom says:

    i am having trouble with step 8 on part IIIa. I get an error when i try to modify the permissions on the busy boxfile. I get the following error.

    ‘chmod’ is not recognized as an internal or external command….

    anything helps.


  14. Tone says:


    It didnt work. When I entered the chmod command in ADB shell, it just spit the line back @ me. No confirmation on whether it worked or not. Also I typed in su and it replied permission denied. I am not sure if the two are related. hope that helps.

    • TheUnlockr says:


      Thanks alot. I’ll be doing a video for this (which always means revising the procedure with the little errors that come up like this one) early next week so I’ll have it done by then.

  15. Tone says:

    TheUnlockr, thanks. I appreciate the effort! I know a visual demonstration will help a lot and will be appreciated by others as well. Keep up the good work!

  16. pablo9060 says:

    i cant get past step 7 on IIIb. i get an error saying… ‘am’ is not recognized as and internal or external command, operable program or batch file

  17. bengar says:

    Today I decided to follow this tutorial, I did the first part, get to RC29, no problem, now, I am in RC29 but when I started the second part the How To Setup ADB procedure, I can not see the USB Debugging on the phone. As I see on the video and the instructions below you it see that you need to have the phone already activated. Remember after I back to RC29 I need to activate the phone touching on the android tap ICON and set up the gmail account. How can I do the second part if I can not see the USB Debugging on the phone.
    Thanks ben

  18. bengar says:

    I did it, but in the step 6 after you see the serial number you need to type this command on the CMD:

    “adb shell” (do not included the quote)

    and then hit enter, the symbol of dollar will be showed on the CMD


    Now after the $ you will need to add the rest of the command:

    am start -a android.intent.action.MAIN -n

    And the pop up screen will be showed.

    Thanks as ever

    Could you get this to work on a Motorola Milestone?
    I’m willing to make a donation up to $200 dlls for you effort.

    • TheUnlockr says:


      I would love to but I don’t have a Milestone to test on…
      Use the contact us form on the site and let me know if you have any other suggestions.

  21. mike says:

    I have a G1 Android. Is there any way to use the wifi without having a data plan?

  22. mike says:

    Am stupid. Pls bear w/ me. My Android says Build Number DRC83. Do I need to change it to RC29?

  23. steven says:

    Hi can someone confirm if this will work. please I want to root my phone. thank you guys!

  24. Chan says:

    Cant go pass
    chmod 755 /data/local/busybox
    it says ‘chmod’ is not recognized as an internal or external command….
    Please I need help

  25. Darrell says:

    This WORKS! I have some very valuable tips. I have t-mobile contract with my old Nokia 6301. I bought a used G1. I had the old owner put in his SIM card and activate it. I then put in MY sim card and then went to Settings > Applications > Gmail and clear all data ( go clear it for all the other google stuff too, like maps, gtalk, etc.). Install the free app ANPDroid via wifi. This turns off all data plans and such so now your phone will only work as a phone, text messages, and data only in wifi!!! PERFECT that’s exactly what I wanted!!! Thanks Unlockr!

  26. adrian says:

    hey i have a question i want to root my G1 phone i know i need androi 1.5 intalled on my phone but my question is… If i intall android 1.5 my phone ask me to ativate with google account? i have not 3G in my area so what can i do to root my G1 without activate my g1 with google

  27. Josh says:

    I’m having a number of problems. I have ADB working but when I type telnetd, nothing happens. Perhaps nothing is suppose to happen but the tutorial gives no further explanation.

    I continued to the push command as described, but as soon as I type in the chmod command I get an error the command is not recognized.

    There are a couple of problems taking place at this point:
    1. It appears I do not have root access, though I have successfully setup RC29. The reason I believe I do not have root access is because the busybox never got pushed over to the G1. I’ve checked the folders on the G1 and there is nothing there. When I type the chmod command, I get an error the command is not recognized.

    2. How does one go about setting up telnet on a G1 locked in the No SIM card screen? The service does not appear to be standard as I’ve come across many tutorials saying it needs to be installed from the market.

    Hope to get some good feedback soon! Thanks.

  28. Josh says:

    A little more detail about the errors I’m receiving…

    c:\android\tools>adb push busybox /data/local/busybox
    1125 KB/s

    c:\android\tools>chmod 755 /data/local/busybox
    ‘chmod’ is not recognized as an internal or external command, operable program or batch file.

    c:\android\tools>adb shell
    $ su

  29. mobstazk says:

    i am trying to login on my G1 phon without a data plan using ADB. finish up to step 7 of the procedure on the unlockr how to forum, but when i type in adb shell in my command prmt i see the $ sign, good but when i type the cmd am start -a android.intent.action.MAIN} }
    error type 3
    Error: activity class {com.settings/settings}does not exist. PLZ some genius help me am in Jamaica

  30. mobstazk says:

    can someone plzs help me solve this am so near and yet so far

    • TheUnlockr says:


      Read what you wrote and what the procedure said, you are missing the -n in the line. Type it EXACTLY as written and try again.
      Good luck!

  31. Michael says:

    If i set up the phone with out the data plan, will i also be able to get picture messaging?

  32. hellcaeser says:

    hey unlockr can you post a list of new custom roms that can skip google account sign in so that i can sign in my g1 like this procedure and flash a rom that can skip google account sign in….

    • TheUnlockr says:


      Sorry don’t have a G1 to do all that trial and error. You’ll just have to load them and see, and then if they have a sign in boot into recovery wipe and load another.

  33. hellcaeser says:

    thankx unlockr..finally rooted and flashed a custom rom,,flashed Donut by laslo 1.2,,can skip google sign in in this rom,,,

  34. Michael says:

    Hey, everything here worked as far as getting WiFI activate, but…

    Even though Wifi is connected with full service, I still get the “Cannot connect to google servers” message or whatever.

    Do you have any experience with this problem?

  35. steven says:

    So after we go back to rc29 do we need to do this step to get it to 1.5 or can we just apply the update? Or do we activate it with this step then apply the update and then can we then use this step to activate it again.. can we use this step as many times as we can???

  36. Julian says:

    im confused how are you supposed to do the ADB process and connect it to your computer if you cant get to your phone since it isnt activated yet. im trying ot find my phone under devices but the computer isnt recognizing it. any help would be greatly appreciated 🙂

    • TheUnlockr says:


      So long as you downgraded to RC29 (like the procedure says lol), then install the drivers etc correctly you will be able to see the phone in ADB.
      Again though read the very beginning of the post. Do you know someone with T-Mobile SIM and a data plan? Just put that in the phone, much faster lol

  37. Maurice B says:

    I can not set up adb, because to set it up i have to be able to mount usb and enable debugging. but none of this is possible from the “touch android screen”

    • TheUnlockr says:


      Just follow the procedure…

      This step enables ADB BEFORE getting past the Touch Android screen.

      2. Open the phone’s keyboard and hit enter once then type the following on the phone’s keyboard:

      setprop persist.service.adb.enable 1


  38. Art says:

    dude cant get pc to detect it at all, xp vista or 7.
    even after step 2 nada……..

    i was trying to do the thing without a data plan and i tried typing the stuff in on the command prompt and it wont work can u help me

  40. jazmin says:

    hey im tryin 2 get da RC29 but its not lettin me download it….wat can i do???

  41. nenad says:

    I have only 3 words for you YOU SAVE ME

  42. john says:

    i am trying to sign into my phone without data plan but one of the steps is to set up my phone with ADB. However, when i go to that section and try to set up ADB it requires that i have access to the settings on my g1… if i cant get sign into my phone, how am i supposed to get into the settings and turn usb debugging on?

  43. john says:

    unlockr, i think maurice and i have the same problem… we actually need to set ADB up, not enable it… and we cant do that unless we can sign into our phones.

    • TheUnlockr says:

      John and Maurice,

      The phone doesn’t need to be past that screen. Just type what it asks you to type in the procedure (that enables ADB to see the phone). The rest is you getting ADB working from the computer to see the phone (installing drivers really).

  44. jhay says:

    hey unlockr,

    I bought a g1 phone from a friend. He factory reset the phone and set up everything so I wouldn’t have any difficulties with the google account login. I have had this phone for a good 3 weeks now. Then whenever I would go to market, and any data plan relating app, it would say his gmail account, and then prompt me to enter a password and says ‘gmail password changed’ but everything was still working fine over wifi. today, just recently, all my contacts got erased and whenever I click the gmail icon, it leads me to a google account set up. I don’t kno how the information on my friends google account got deleted, but now I cannot even add contacts, it always force closes.

    is there anyway to create a google account without the data plan just so I can data sync contacts to my phone? or at least add contacts?

  45. david says:

    hi unlockr and other users i was wondering if there is a similar process for the mytouch 3g i do not have a data plan and im stuck in the activation screen and dnt kno anyone with t mobile data plan is there any way you can help me? i will really appreciate any help 🙂

  46. Don says:


    Are there any tutorials to do this for Linux????I run OpenSUSE linux….Thanks a bunch…

  47. michael says:

    thank you verrrrrry much man you have been a great help thank you …..

  48. michael weathers says:

    my g1 is working fine without a data plan thanks to the unlockr…!!!thanks again it took me 2 day to figure it out but it was worth it thanks man…

  49. Kevin says:

    Is the data plan for 1 day only for $1

    • TheUnlockr says:


      Yes. It is $30/month and they prorate it. So if there are 30 days in the month and you use it for one day, that is $30/30 days x 1 day = $1 (ish)

  50. Isaak says:

    Can u plz help me cuz when i was tryin to do the setup without using data plan and when i was doin to command prompt its said AndroidSDK\Tools\ is not recongized

    PLZ HELP ME!!!

  51. jeff says:

    Hi my name is jeff i buy a HTC G1 from someone in united state,the reason he sale it to me is because he didnt know how to use it so….. me right now i’m in france with the phone i will want to use it to a french operator n the name call SFR but the thing is i went to unlock it they toll me is unlock but they didn’t know how to make it works cause they was asking on the phone the only thing i could do is to make emergency call thats all so i will want to know if you could me……. also they be asking me to do a Gmail account i did it but still don’t want to work…… my french sims card is not a plan its a prepard card i will want to no if a will work or if you could help me to work this G1 thanks

    • TheUnlockr says:


      Do this procedure and it will let you connect to WiFi then you can get past the activation screen. Then if the phone IS unlocked you should immediately be able to make phone calls and send texts etc.

  52. jeff says:

    im doing that just now but the thing say the system cannot find the path specified a also say adb is not recognized as an internal or external command, operable program or batch file

  53. Dave says:

    I plan on buying a new phone fairly soon and would like to give my G1 to my grandson to use as a texting phone (no data plan). It would be nice, however, if he could connect to a GMail account of his own for backing up contacts. Obviously, the phone will be activated when I take my sim out and he puts his in, but it would be my Google account. Would you recommend the second step–activating the data plan for a day?

    • TheUnlockr says:


      Sure. I would recommend going into settings > security (it might also be in sd card or privacy, they moved it depending on what version of Android you have on the phone) and do a Factory Reset of the phone. This will erase everything and then reboot the phone. When you get to the login screen say that you don’t have an account with Google and create one for your grandson to use (unless he already has a gmail then do I have an existing account, but put HIS info in instead of yours). Then once you get to the home screen, take out your SIM and put his in. Done. Now he’s activated and it has his GMail account.
      Just make sure he doesn’t ever factory reset it, or he’ll have to do that again.

  54. Dave says:

    Thanks for the reply–great solution!!!

  55. Brad says:

    Can i upgrade my fone after activating it??????

  56. Blair says:

    Having the same problem as Michael, with the wifi. Followed the tutorial, got the wifi on & reading a signal. However, I still get the “Cannot connect to google servers” message & noticed that I get 2 different wifi signal strengths. At the top of the main screen or homepage, the wifi icon shows but reads no signal, but in the wifi settings page or screen, where it shows that I’m connected, it clearly shows a full signal strength. Did I miss something or is there a hardware issue of some kind? Why don’t both icons show the same signal strength & does this contribute to my being unable to connect to the internet?

  57. Yusuf says:

    I got the phone from my cousin and well basically i just want to use this as a media device without a sim and i’ve tried using adb etc. but i have no clue whats wrong with it i get the $ symbol on msdos but when ever i put a command in the line sends bakc a message that says i have no permissions

    • TheUnlockr says:


      Find your cousin (or anyone with a data plan on T-Mobile). Put his SIM that had a data plan on it in the phone, activate it using your GMail account, then take out his SIM and give it back to him. Easiest way to solve it.

  58. John says:

    I tried the steps to many time. it will not what so ever list my device under the command prompt . do i have to have Administrator privileges to install the t mobile g1 hardware to the computer because the Administrator of this computer is long gone. and every time i repeat these steps it asks for the password too many times

  59. jesus says:

    hey can you please give me the htc g1 drivers .you didnt post them please i need them fast

  60. CharlesC says:

    Any way to do this same procedure with a MyTouch 3g?

  61. CharlesC says:

    Any chance of getting a version of this working with the MyTouch?

    • TheUnlockr says:


      Not this procedure since we need the physical keyboard to input things with. The easiest way to activate the phone is either add the data plan to your phone for a day (cost you $1) or borrow a friends SIM with a data plan activate the phone and put your SIM in.

  62. Ian says:

    okai ive done up to step 6 on IIIb….Buut my computer still wont give me a serial number I suspect its because my phone isnt mounted to the computer…. but i cant mount it to thee computer because it wont let me past thee sign in….

    PLZ!!!!!!!! HELP im too close to quit…………………=]

  63. Kim says:

    hi, i am trying to use my g1 without the data plan on my sim card and when i first turn it on, i hit answer and proceed to type but i dont have a search bar like you, please help

  64. Dave says:

    I’m back!! As noted above, I followed Unlockr’s advice and activated my G1 using my sim but my grandson’s Gmail account. However, even though he connects to WiFi, the phone will not connect to any Goggle services including email, maps, or the app market. Is there something I have to do to work around this? Thanks!

    p.s. Loving my Nexus One!

  65. Kyle says:

    I got through all of that but when I go to sing-in with my gmail account to try and activate it, an error comes up saying “There is a problem communicating with the Google servers. This could be a temporary problem or your SIM card may not be provisioned for data services. If it continues, call Customer Care.” I don’t have a data plan on my SIM but I shouldn’t have to right after I set up the wifi right?

  66. VBeezy says:

    im getting a G1. but i dnt have the internet data plan, could i possibly use someone sim that has the internet for a mytouch. or would it need to be for a G1?

  67. everett says:

    Thanks a lot, great guide!

    Just one thing though. In step II, you instruct not to continue until you see the phone’s serial number in adb. It seems like this is a flaw in the guide because, for me at least, I was not able to see my serial number in adb until I did step IIIb, #2 through #6.

  68. RE says:

    same problem as some above. Got to ADB with drivers updated. But adb devices doesnt return anything, just “List of devices attached” but nothing there. I read somewhere the USB debugging should be on, but that requires acitvating the G1 first. Am i doing something wrong? I can not pass step IIIb-1 since adb doesnt link with the G1

  69. Keith says:

    I have a question. I bought the phone off a friend and it was activated, but I needed to factory reset it because the SD card on it was messed up. I forgot you had to activated once the phone is factory reseted. So my question is, does the phone have to have wifi on BEFORE you already Reset the phone? Or is there a way to turn on wifi after it’s already reset but cannot be registered?

  70. 007Bond says:

    nice tutorial, but I have a question. I have MT3G. I realized that when you’re on activation screen, if you hold the “MENU” button, the keyboard comes up. So I was wondering if you could use these instructions on MT3G..?

  71. jerry says:

    when i put in “adb devices” it say “list of devices attachted” then i put “adb shell” and it says phone not connected

  72. hesham says:

    u r the best duuuuuuuuuuuuuuude!!!!!!!!!!!!!

  73. Mondy says:


    Wow! looks like you have done a great job helping others. I bought a used G1 to use it as Internet Access device (like I-Touch) and get familiar with Android. This was a T-mobile phone and is not unlocked.Without the SIM the phone would not let me do anything. I have an old T-mobile SIM which I took out of an old phone and put it in G1 and got intial screen upto “Touch Android”, but I can’t go beyond. I do not want to use the phone feature, but want to use for web surfing through home wifi. What is the best way to solve this issue?

    • TheUnlockr says:


      Either have a friend with a data plan on their T-Mobile SIM put their SIM in the phone so you can activate it then just take their sim our after. Or do this procedure…

  74. Mondy says:


    WOW AGAIN!!! your solution works. It took me a while to get hang of downloads on my laptop and the device, but works like a charm!!!!!!!!!!!!!. THANK YOU!!!!!!
    I am new Android user and more I look at the speed, the “market”, the functionality, etc., the more I am getting amazed. I am not using it a phone but a cheap internet access device. I now need to slowly upgrade the android version. Any idea if G1 supports Android 2.2?
    Keep up the great work.

  75. Jason says:

    Thanks for this video… I thought I was going crazy trying to get USB debugging working. in the end, I had to use a third machine with a fresh install of XP before it would recognize the ADB “Android Phone” device… I hate those usb drivers! I see a lot of other people in various forums who may be having the same problem.

    Anyway, thanks again!

    and also how am i supposed to activate debug if i cant get to the phone settings :S i have a G1

  83. Martin says:

    Using ‘adb shell’ the response is ‘error more than one device an emulator’
    or sometimes ‘devices is offline’. Problem? Solution?

  84. patricia says:

    so after i unlock my tmobile g1 does that mean i can put it to boost?

    • TheUnlockr says:


      Please click on Wireless 101 at the top of the site, then click on General Wireless 101 and then look for the article call Android 101: Rooting, Jailbreaking, Unlocking and read it. Then look for Unlocking 101: CDMA vs GSM and read that as well.
      After that you’ll have a better understanding of what you just asked.

  85. patricia says:

    ok so im going to be completely honest with you. im slow when it comes to doing stuff like this. i dont know where to download the sites from or anything like that. my phone just wont go past the android guy. well past the log in screen. 🙁 i would really apperciate the help

      1. The easiest way to do it would be to just either add the data plan for one day to your account (just add it then remove it tomorrow) – it will LITERALLY cost you $1 for a day’s usage. OR just borrow a friend with a T-Mobile SIM card with a data plan to activate the phone and then put yours in once it is activated.
      2. You need to go back to RC29 with rooting because that version has the exploit we use for rooting in it.

      Good luck!

    can you send me a link how to do it that way with the procedure of hoy to go back to rc29 and rooting it without a data plan

  88. Jagrut says:

    and also will rooting cause the phone to screw up…i have no warrenty anyways lol. also what should i do if something goes wrong in the middle what should i do then

  89. OneConfusedGuy says:


    having some serious issues with this whole process. i downgraded to RC29 and all that jazz, but I can’t get the driver part to work (I think, no serial appears after running the commands). Using windows 7 and a g1. Any ideas?


  90. jay says:

    what if step 6 dosent work

  91. how would i use someone elses sim card when i would have to take the battery out to put my sim card back in should it still work? (its the g1)

    • TheUnlockr says:

      Once its past the activation screen you can turn it off and on without having to reactivate it. You’d only need to do the activation screen again if you factory reset the phone (swapping sim cards is fine).

  92. blabla says:

    how am i supposed to activate debug if i cant get to the phone settings :S i have a G1

  93. Meanna Juke says:

    How can I mount my g1 to my pc if my g1 has never been activated and I can’t access it at all! PLEASE HELP ME! I don’t live in the US and I bought the phone on ebay so it’ll be tough trying to send it back! Please Help!!!

  94. TANK says:

    how do i do this on windows 7

  95. franck-o says:

    I just reset my G1 and I am having problem following the procedure. I’m from Canada so i don’t have acess to a T-Mobile simcard. Do it will work if i borrow my friend sim card(other than t-mobile) with a data plan on it.

    thank you

    • TheUnlockr says:

      Is the phone unlocked? Have you used a non T-Mobile SIM in it before? If so then you can use any SIM card so long as it has a data plan.
      Just make sure when you get to the Activation screen, you push the Menu key then hit APN, then either choose your carrier from the list or hit New, then put in your carrier’s APN settings in, hit Save and then select the APN and hit back.

      • franck-o says:

        Sorry but i new in cellphone world !!!lol what is the APN??

        thank you

        • franck-o says:

          I reset accidently reset my G1. Then I use my brother sim card and I unlock it with is sim card. Today I borrow my cousin simcard to activate my cell, he has a data plan. But the phone didn’t dectect the connexion… desperate i don’t know what to do. …. please help me

  96. franck-o says:

    If i have a rogers(in canada) sim card with data plan will it work to activate it, without unlock it???

    Thank you

  97. MinaM says:

    is it just to unlock the g1? can i use the method of putting in a friend’s sim card that has the internet plan into a motorola cliq and then taking it out and putting mine in?

  98. jesse says:

    does it work?

  99. jesse says:

    does it work?

  100. Yona says:

    This has been quite helpful. Although the only solution I had was to use a SIM with Data to reactivate. The phone had RC30 and I could not find out how to return it to RC29.


  101. this actually works but make sure to download PDANet —> & In Number2, part2 of the PDANet install on this website this is the driver needed to install for the G1 —> extract the contents into a new folder on your desktop. when you browse for the file look in your desktop for the files you just extracted. Thanks So Much To ALL The Developers And Hacking Community

  106. selena says:

    if you are sarting up your g1 with a sim card from another country.. does it work with a prepaid card or does someone that has a internet planner?

  107. Guest says:

    Will using someone eles’s SIM still allow us to connect to the internet afterward using wifi?

  108. GeekonaBike says:

    Has anyone been able to install the ABD drivers in windows or Linux with an unactivated phone. every approach I’ve tried so far want the phone mounted or USD debuging turned on.

  109. GeekonaBike says:

    What worked for me (Tmobile G1) after a few tries was at Step II 1 not getting serial# – uninstall HTC driver using USBview, unpluging phone. follow steps & replug phone at step IIIb 6
    Now the correct drives installed including the ABD driver

  121. g1user says:

    Did the ‘easy route’ by taking my sim card out & putting in another sim card. If I was registered on the g1 initially, how do we have the other person register on it afterwards?, and it seems as though data/web is working on the phone even though the plan for the sim card that is in it doesn’t have the data plan on it – your thoughts?

    Mad props

  140. Daniel Jones says:

    Instruction II.1 is wrong. If you are trying to activate it without a SIM card or a data plan, that means it’s obviously not activated. If the phone is not activated, you can’t turn on the USB Debugging on the phone. If you could come up with a solution that works, please, let me know. I’m at a dead-end here, and becoming more and more frustrated with my failed attempts to connect to ADB. I can’t get past the activation screen (I have a Blackberry data plan, not an Android plan, so I can’t activate my gmail account with my SIM) to turn on USB Debugging. Any help?

  141. estebang_12 says:


    I did the proccess with the option IIIb.
