thumb 550 BACKFLIP Motorola Multitouch How to Root Motorola Backflip 1.5 with the rageagainstthecage method

First of all make sure you have the following installed and setup.

  1. Download Motorola Backflip USB drivers for 32bit/x86 or 64bit/x64 and install.
  2. Download the android sdk and extract it in your c drive and check if adb.exe is present in “c:\android-sdk_r07-windows\android-sdk-windows\tools”
  3. Download the rageagainstthecage file and unzip and extract to c drive and make sure two files and two folders are present in “c:\Moto_MSM_Root”
  4. Download this backflip-1.5.bat batch file and save it on your desktop or other place you like.
  5. Download and install “Terminal Emulator” from market on your Motorola Backflip.

Steps to root your Motorola Backflip 1.5 (Credit: Skrilax_CZ)

  1. Plug in your Backflip to the computer, and Turn Off the USB Drive on phone.
  2. Make sure its connected in USB Debugging mode. [Settings->Applications->Development->Check USB Debugging]
  3. Run the batch file you downloaded in Req. No. 4 by double clicking on it. If a screen shows up and stops at a “$” prompt for you then its ok. If the black screen closes instantly make sure you have extracted the files correctly as mentioned in the requirements.

  4. Open the “Terminal Emulator” on your Backflip, that you installed from market and type:
    cd /data/local/tmp
    ./rageagainstthecage-arm5.bin

    Wait until you see this message – don’t press anything:

    [+] Forked xxxx childs.
  5. Then press enter and type “exit” to close the terminal (or close it via the menu)
  6. Open the Terminal Emulator on the phone (if you get the message that terminal died, dismiss it and run it again)
  7. If you end up with “#” prompt, do the following. Otherwise reboot the phone and try opening the “Terminal Emulator” again. If even that doesn’t give “#” prompt, then go back to step 4.
  8. Type the following into the Terminal Emulator on your Motorola Backflip:
     . /data/local/tmp/install-root.sh
    (if the script prints nothing, then it was successful)
    exit
    exit
  9. Now your Motorola Backflip 1.5 is successfully rooted.

Code in backflip-1.5.bat

cd c:\android-sdk_r07-windows\android-sdk-windows\tools

Hi,

Installed as per instruction, on my Vista laptop, but not able to ROOT my phone.

When running the batch file by double clicking on Batch Files black screen closes instantly.

Krishan,
make sure you have extracted the sdk to c drive and after extracting it to C drive your path looks like this “c:\android-sdk_r07-windows\android-sdk-windows\tools”
and the other archive sits like this “c:\Moto_MSM_Root\1.5\” ..
connect the phone -> turn off usb drive(set it in pc charging mode) -> thirdly enable USB Debugging by going to [Settings->Applications->Development->Check USB Debugging]
Now double click the batch file.

Dear Keshav,
Hi
We have 2 carriers like AT&T in Iran”MTN and MCI”.
My Back flip work with MTN perfect but with MCI doesn’t work.
I cannot answer the incoming call and for outgoing call I just talk 15sec.
Ask from any dealer about this problem, told me your phone is locked and you must be buy a registration code from factory for solved this problem with 70$.
Do you know how can I cracked and unlocked the back flip?
Thanks

11 Keshav Gupta December 19, 2010 at 12:36 am

dude you don’t have to get any unlock code..as its already unlocked – as you are able to call with MCI
There is a problem in network strenght at the place where you are using your phone with MCI

Dear Keshav
I recently moved from u.s.a. back to canada and At&t U.S.A. wont give me the code to unlock my At&t/Motorola Backflip is there any way I can unlock it myself? Will rooting my phone allow me to unlock/switch carriers? Thank you for your time.

Reply

17 Keshav Gupta December 23, 2010 at 12:49 pm

Dear Jason,
Right now rooting your phone won’t help in getting the your phone unlocked!
What you could do is, If you still have your AT&T sim, call customer care from that number and tell them that “I are going abroad for 30 days and will be needing to use some other SIM, and don’t want to buy another phone for same. So give me the unlock code.” be persistent in what you say ask the other CC exec if first one doesn’t give you the code.
Else you will have to buy an unlock code from numerous sites already there in the wild.

I am not able to install Terminal Emulator on my backflip. I have downloaded the file from your link but i dont know how to install it on my phone. So i am not able to root my phone.

Reply

19 Keshav Gupta December 23, 2010 at 8:01 pm

Saif,
you can download connectBot instead of terminal emulator on your phone.. It will serve the same purpose

Reply

20 Saif Ur Rehman December 24, 2010 at 12:52 pm

Dear Brother,
I also tried to install connectBot and that application downloaded on my backflip. When I tried to run that application, I encountered the security problem and my phone didn’t allow the application to run. My backflip is from US At&t and At&t doesn’t allow any third party software to installed on phone. Even many application on backflip use At&t network so that At&t could charge their customers without informing.

Regards,

Saif Ur Rehman.

21 Keshav Gupta December 24, 2010 at 2:33 pm

Dear Saif,
Connectbot and terminal emulator should work as you downloaded them from the android market only!!
Your phone has some other problem I suppose reset your phone by going to settings -> privacy ->factory data reset
then try rooting again

Hey Keshav,

I’m having a bit of trouble with step no.4 whereby in the Terminal Emulator when I attempt to input the two-line code, on the second line I receive the following error:

“./rageagaisntthecage-arm5.bin: not found”

I’ve double checked that I’ve placed all the downloaded folders/files in their correct places and I’ve also got the debugger enabled and the USB mode off.

Any idea what might be the problem?

Thanks.

this issue has already been mentioned in the comments.. the location of your sdk files and the moto msm root is not correct…
place it in the C:/ not anywhere else
open the batch file and see where the batch file is searching for adb.exe and the rageagainstthecage file

HI Keshav,

Bro, I know that i have not been able to drop this line to you earlier, however i would like to mention that I love the way to write your tutorials, this has helped me to upgrade my phone to 2.2 froyo.

I just wanted to check few things with you in case you can help -
1) the phone now is showing some files which should be hidden (Only happens sometimes) – That is the files like subparts of a call made in the phone list. OR multiple copies of a same image showing on the screen when i go into gallery.
2) The camera (As mentioned by you) does not click multi shots and even the flash is causing issues. Kindly suggest, if there is any way to solve this.
3) is there a taks killer that i should install from market for Froyo – Which one would you recommend.

Please let me know if It would be a good idea to format the SD card (8GB card that i have in this phone) – Also advice if i should partion the memory.

Regards

Reply

52 Keshav Gupta March 7, 2011 at 12:40 pm

Hi Inderveer,
1. Subparts – thats a feature. And multiple images may be because you have an old database of thumbnails cached on your sd card. you can remove those by going to “/sdcard/DCIM/.thumbnails”
2. You can try Camera360.
3. ES Task Manager – is the one i use.
4. No need to repartition or format!

I am trying to root my MB300 i did everything as mentioned.
you hav mentioned in step 8 dat nothing should come after typing

If someone has the same problem than me, just go to http://www.filecrop.com/android-sdk-r07-windows.zip.html , download one of the r07 sdk zip, unzip it in c:\ (no need do uninstall sdk r12 if you have install it and you are using it so you don’t have to download all the pack again …)
And that will do the trick for backflip 1.5 file
