[Motorola Droid 3] dasilva333:
I've been struggling installing custom roms on my phone so I figured I'd document the process to help out anyone else starting out. I'd like to thank everyone for helping me figure this out and for the hard work of the community for making this possible.

Edit: My goal was to come up with a way to install CM9 while leaving the original system it came with and all my settings and apps. I understand how to do TitaniumBackup and how to save specific apps/files to but I wanted an exact backup of my original system alongside any custom rom so I just wrote down the steps I used to make it happen.

Root the system

1.First apply one click root using this tool

2. Install this apk onto the phone and click the first button then the second button

5. Reroot using 2.3.6 Zerg tool

Basically after flashing with RSD Lite then re-root using this tool:

6.Re-install CWM (Droid 3 Bootstrapper from step 2) and then apply the Bell rar file as a nandroid restore.

7. Reboot into the system and let the OS load again then re-install cwm (no need to reroot) and reboot back into recovery.

the trick to booting into recovery the second time is to turn the phone off, hold the m key while pressing the power button, plug in the phone to usb, choose bp tools

restore your original backup from step 3 using advanced restore and restore the Data only and then wipe cache and dalvik cache

8. Remove CWM and install safestrap instead it involves using adb shell and removing certain files instructions found here:

9. Install SafeStrap once CWM is removed just install it, reboot and press the menu key while booting

10. ICS Install, at this point you have prepped your system so you can install CM9 otherwise it won't boot on the stock Bell 2.3.4
