How To: Load a Custom ROM on the Motorola Backflip

I. Before You Begin

1. You must have done our How To Root procedure.

II. Flash a Custom Recovery Image

1. Download the custom recovery image .zip file and extract it to the tools folder of your AndroidSDK on your computer.

Backflip Recovery (Updated 9.18.10)

2. Plug the phone in via USB cable and make sure USB Debugging is checked ON still from the rooting procedure.

2. Open a command prompt on your computer by clicking on the start menu and typing cmd and hitting enter in the search box.

3. In the command prompt type the following with hitting enter at the end of each line:

cd\
cd c:\androidsdk\tools
adb push recovery.img /sdcard/recovery.img
adb shell
su
flash_image recovery /sdcard/recovery.img

4. Now that the new recovery has been flashed, we are going to make sure the old recovery doesn’t get put back. In the command prompt type the following with hitting enter at the end of each line:

mount -o remount,rw -t yaffs2 /dev/block/mtdblock3 /system
cd system
rm recovery.img

III. Load a Custom ROM

1. Head over to Google and search for Backflip ROMs section and download the ROM you want to flash.

2. Plug in the phone to the computer and mount the sd card (so we can transfer files to it).

3. Copy the ROM’s .zip file from the computer to the root of the sdcard (NOT inside any folders just on the sdcard itself. Do NOT extract the .zip file, leave it zipped).

4. Once it is done transferring, unplug the phone and turn it off.

5. Turn the phone back on by holding down Camera Button and Power and keep holding it until it says to let go. Then click Volume Down for the recovery screen to come up.

6. Select Wipe Data and do a wipe.

7. Then select Apply Zip and select the ROM file you just saved to the sdcard.

8. Once it is done flashing, select reboot now and wait a while for it to reboot. Once done, you are on your custom ROM.

9. To switch to a different ROM, simply redo Section III only with a different ROM file.

    But there are no existing roms for the backflip at your link to download….??????

    • Jimmy Pop,

      Noone has submitted any yet. Feel free to if you find one on another site!

    Ehh… Nice guide, but you don’t have any ROMs in your Backflip ROM section…

    • Ingramm,

      That is because noone has submitted any 🙂 Feel free to if you find any on other sites and we’ll link them in that section so they can all be found in one place (the Backflip doesn’t seem to have too many custom ROMs yet, but that might change now that the rooting is a lot easier).

      • Sketch

        in the tut vid that was a cliq phone….. would those cliq roms work on a backflip?

        • Sketch,

          The rooting procedure is the same but not sure if the ROMs will work the same. You can try just make sure you do a nandroid backup in recovery first. Let us know if they work!

  • That is not the proper recovery image to use for the Backflip. It is the MB501 CliqXT recovery image, and does not work on the Backflip. Try it, you can navigate the menu and that’s about it. Pressing “Home” does not select your choice, so there’s no way to do anything using this recovery.

    Why not use the proper one for the MB300 Backflip? It was made by the same individual.

    Help PLEASE!

  • Finisher1214

    rm failed for recovery.img, No such file or Directory.

    Need help soon and please just comment back n the site.

    • Finisher,

      That command removes the recovery, so if it says not found, problem already solved, just continue. (Also make sure you cd’ed to the right directory before typing that in).

  • motob

    yup thanks to ur page im rooted and flashed the rom love it gd looks unlockr

  • mb

    thank you for the root and loading custon roms. i dont know if anyone has said this but i have tested 2 motorola cliq roms and they did not work..

    @poster and oldman:

    To flash the recovery image go to your superuser app on your phone. When you ask for su permissions in abd shell your superuser app will ask for permissions. Grant them.

    I was having the same problem until I did a simple search in google “adb shell su permission denied” the first result gave the solution 🙂

    at abd push recovery.img /sdcard/recovery.img it says error: more than one device and emulator???

    This walkthrough makes rooting and flashing custom roms SO EASY! Thanks a billion my phone can do so much more now its not stuck on 1.5

  • Sooooooooooo i didnt do the entire section 2 process, and instead wiped everything from my phone. I try and install the ROM and it says no file exits ‘/sdcadr/update.zip or something like that. Help?

  • And now everytime I try to back up the phone on the customn backup screen, it’ll say error : run ‘nandroid-mobile.sh via abd!’

    Fml wtf. WHAT DOE THIS MEANS?

  • NVM SINCE NO ONE REPLIES

    You have to have enough space on your sd card. so delete all your music. 😛 I had 1.6 GB of music. lololol ooops.

    took that off, then preformed the backup for the rom thing. 😀

    Hey! In the picture of this post, it’s an HTC looking thing. Sorry if I sound noobish, but getting to the point now 😛

    Basically I’m asking, is there an HTC ROM I can install that allows full/most HTC sense? I love my phone, but I hate the motoblur interface. Why I didn’t get an actual HTC phone? I honestly don’t know. There’s a few backflip features that I couldn’t resist.

    Please, if anybody has an HTC sense ROM, I will love you forever. And if I had it, I’d give you a million dollars 😀

    Thanks

( only place i could find roms were at modmymobile.com i used speedy rom)

    • rachael

      this isn’t the root. this is a custom rom. i’ve already done a root. im concerned about the android 2.1 upgrade the backflips got. will these recovery files push me back to 1.5 if i have to flash recovery? i don’t use this phone any more. im using it as a test bed to learn about rooting and stuff but i don’t want to screw it up either.

  • im on the last step and it say rm failed for recovery.img, no sucj file or directory.

  • Major Jones

    Is the directory to delete the recovery.img file from supposed to be system or sdcard.
    When I type
    cd system or cd sdcard
    rm recovery.img
    I get a no such file or directory error
    Should I instead be deleting recovery.img from sdcard directory not system, we pushed the original recovery.img to sdcard not system
    cd sdcard

    • Major Jones

      I believe where it says
      cd system it’s supposed to say
      cd sdcard then
      rm recovery.img
      we pushed the recovery.img to the sdcard n ot system, it must be a typo

  • rm failed for recovery.img No such file or directory.
    Your tutorial says push the recovery.img to /sdcard/recovery.img however, when you run the rm command you are trying to do it from system. should we be typing, cd sdcard insted of cd system, after
    mount -o remount,rw -t yaffs2 /dev/block/mtdblock3 /system
    and then rm recovery.img?

  • andy

    the link to the recovery image doesnt work out

  • Williamf117

    ATTENTION EVERYONE: I had the “CAN NOT LINK EXECUTABLE” issue, and I finally solved it, the issue was caused due to an “su” and “superuser.apk” that would not work in the Android 2.1 version, here is the download link to the Su and Superuser.apk for the Backflip owners that have Android 2.1 and have the “Cannot link executable” issue. Just change the su and superuser.apk inside the file you will download for the ones you had previously, root again, and you should load a ROM using the method described in this site, or using ROM MANAGER. Thanks, hope it is useful.

    This tutorial should point out that you need to rename  whatever the zip of your custom rom is called to “update.zip”. I didn’t know and almost bricked my phone, since there was no way to rename it and recovery wasn’t working 90% of the times I tried it.
