How To Install a ROM on the Motorola Droid Razr with Safestrap Recovery

Now that you have installed the Safestrap recovery, You probably want to flash a custom ROM. If you are familiar with Clockwork Mod recovery, then you will feel right at home as there are only a few (yet important) differences.

Before You Begin:

  • You must have a rooted Droid Razr. Click here if you have not done this yet:
  • No other recovery application or recovery can be loaded. 2 different recoveries (safestrap and bootstrap) loaded together is a bad thing and bad things will happen. Make sure if you have installed bootstrap previously, that you remove the recovery and remove the application from your device.
  • You also must have installed the Safestrap application and recovery. Click here to see how:

Choose a ROM You Want to Flash:

  • Download a ROM of choice for the Droid Razr and put the zip file on the root of your SD card. If you download the ROM from your device, you will probably need to move this from the ‘sdcard’ (internal flash memory) directory to the ‘sdcard-ext’ (external flash memory).
  • It is always a good idea to verify the checksum of the downloaded ROM file. Most developers provide the MD5 checksum. You can check this using your phone by downloading a free app like AFV (Android File Verifier).

To access the Clockwork Mod Based Recovery:

  • Power down your phone.
  • Power your phone back on and when prompted, press your capacitive menu button (if you do not do this within 10 seconds of being prompted, you will reboot into your current OS).

Make a Backup:

  • The top of the screen should show “Safestrap System is: Disabled” (that is what we want right now and is also referred to as “Non-Safe mode”).
  • Using your Vol+ and Vol- keys, navigate to the entry labeled “backup and restore” and use your power button to select it.
  • Select “backup” and give it 5-10 minutes to complete a full backup of your current stock ROM (this isn’t required but it is always a good idea to make a backup before you install new a new ROM or make any changes to your system files).

Enter Safe Mode:

  • Navigate to and enter the “safe boot menu”.
  • Select “Enable Safe System”. This will take a couple of minutes to run as it backs up some files (similar to what we did previously, but for different reasons). This backup that is being made is part of why this recovery is called Safestrap as you can actually disable safe system later to boot into your normal stock ROM without flashing or restoring anything manually.

Prepare to Install ROM:

  • Caution: This will erase all of your user applications and settings. Files (pictures, documents, downloaded files etc.) on your internal sd card as well as you external sd card will still remain.
  • In the main menu of the Safestrap recovery, navigate to and select “wipe data/factory reset” – then confirm and let that run (5 minutes or so).
  • Navigate to and select “wipe cache partition” – then confirm (this is done pretty quickly).
  • Next, navigate and enter the “advanced” menu
  • Select “Wipe Dalvik Cache” – then confirm (again, this is pretty quick)
  • Navigate to and enter the “mounts and storage” menu
  • Select “format /system” – then confirm. This formats the 2nd system partition that was created when you first installed the Safestrap recovery. Your original ROM’s system files are left untouched (again…this is why it’s called Safestrap).
  • Use the *****Go Back***** link at the bottom of the screen to get back to the main menu and select “Install zip from sdcard”
  • Now select “choose zip from sdcard” and navigate to the location on your external sd card where you placed your ROM zip file and select it using your power button. Then confirm the install when prompted
  • Again, use the *****Go Back***** link at the bottom of the screen to get back to the main menu and select “reboot system now”.

Reboot your device and walk away once you see the new ROM has loaded and you are greeted with the welcome screen. Give the new ROM a chance to settle in (5-10 minutes is good). This may sound unnecessary but it usually helps with initial problems and apps force closing when you do this.
