  5. Drag n drop adb.exe again in command prompt and type “shell” and hit enter.
  6. type “su” enter and approve the request on phone if prompted, then type
    flash_image recovery /sdcard/recovery.img
  7. Now you have custom recovery on your phone. #Milestone – 1
  8. Reboot phone in recovery mode – power off phone –> press and hold camera button –> switch on phone while keeping camera button pressed.Phone will enter fast boot, immediately press volume down key(though will say up pressed) and wait until recovery loads.
  9. On your recovery menu goto Wipe and select “Wipe all” this will delete all data and cache off your phone. rec2
  10. Press back button to go back to main recovery menu and select “Flash zip from SD”. You’ll see the text “SDCARD: update-cm-7.1.0-BACKFLIP-signed.zip”. Press the home key. ROM will begin flashing 🙂 rec3
  11. After flashing the Gingerbread you will have to flash the Gapps you downloaded to get Android Market etc.
  12. After completion, select “Reboot system now”. It may take up to 10-15 minutes to boot for the first time.

13 neimar July 14, 2011 at 5:37 pm

Can I update a AT&T backflip from android 2.1 to 2.3?


14 Schazz July 18, 2011 at 6:18 pm

I did the same and found no problem.


15 jericho July 14, 2011 at 6:21 pm

i think this latest ROM is without MT ? Correct me if I’m wrong. Update if direct from 1.5.

Everything else is excellent. boot up time reduced significantly from 2.5mins (froyo) to 1.25mins


16 basava August 9, 2011 at 1:14 pm

Works perfectly and faster than froyo… thanks a ton brother…


17 Anish August 16, 2011 at 9:11 pm

Simply Awesome!!!!!!!!

Thanks a lot!!


18 Himanshu August 16, 2011 at 11:52 pm


I a really Thankful to you for providing this update.
As for in India, there won’t be any upgrades from 1.5 from motorola, which is disheartning. So, work like this is commendable.

20 Keshav Gupta August 24, 2011 at 1:04 pm

Yes, works on all backflips


21 Michael August 23, 2011 at 10:42 am

Is Flash Player 10.3 supported with 2.3.4? I can’t install it on my Backflip.


22 Keshav Gupta August 24, 2011 at 1:01 pm

Not supported, as the CPU in backflip is ARMv6 and minimum ARMv7 is required for flash as of now!


23 Michael August 23, 2011 at 10:14 pm

Can I delete the GApp, CM7, and recovery.img zip files after I have finished the update?


24 Keshav Gupta August 24, 2011 at 12:59 pm

yes, you can delete them


25 Sanjeet September 5, 2011 at 11:26 am

Hi Keshav,

My mistake. Instead of copying the zip of update and gapps on the SD card, I unzipped it on the PC and then copied it on to SD. Thanks you very much for this update. Ive just installed it and it works great – no issues so far. Thanks again.

I have been trying to find a copy of Z4root for my Motorola Backflip MB300. Unfortunately when I download from links I find on the internet my antivirus software identifies a virus in the download and deletes the file. I tried the “One Click Root” website it tries to root but is unsuccessful. Their list of phones supported does not include the backflip. Mediafire has deleted the software.

Do you have a copy or know where I can download one?
Thank you for any assistance you can provide.



35 MotoUser August 22, 2013 at 2:28 pm

Hi Keshav ,
