Install LineageOS on
Motorola DROID RAZR (GSM)

Basic requirements

1. Read through the instructions at least once before actually following them, so as to avoid any problems due to any missed steps!
2. Make sure your computer has adb and fastboot. Setup instructions can be found here.
3. Enable USB debugging on your device.
4. Make sure that your model number is one of the following (exact match required!):
   • XT910
5. Boot your device with the stock OS at least once and check every functionality.
   warning

   Warning: Make sure that you can send and receive SMS and place and receive calls (also via WiFi and LTE, if available), otherwise it won’t work on LineageOS either! Additionally, some devices require that VoLTE/VoWiFi be utilized once on stock to provision IMS.
6. LineageOS is provided as-is with no warranty. While we attempt to verify everything works you are installing this at your own risk!

Unlocking the bootloader

1. Connect the device to your PC via USB.
2. On the computer, open a command prompt (on Windows) or terminal (on Linux or macOS) window, and type:

   adb -d reboot bootloader
   

   You can also boot into fastboot mode via a key combination:

   • With the device powered off, hold Volume Up + Volume Down + Power.
3. Once the device is in fastboot mode, verify your PC finds it by typing:

   fastboot devices
   

   If you don’t get any output or an error:

   • on Windows: make sure the device appears in the device manager without a triangle. Try other drivers until the command above works!
   • on Linux or macOS: If you see no permissions fastboot try running fastboot as root. When the output is empty, check your USB cable and port!

4. Follow the instructions at Motorola Support to unlock your bootloader.

   Note: Some newer Motorola devices have a waiting period before you can enable OEM Unlock option in the developer options. It can sometimes take up to one week.

   Note: If your device is not supported by the Motorola Bootloader Unlock website, you may be able to use an alternative bootloader unlock method like SunShine, though they only support some devices/firmwares.
5. Since the device resets completely, you will need to re-enable USB debugging to continue.

Installing a custom recovery using fastboot

1. Download a custom recovery - you can download TWRP. Simply download the latest recovery file, named something like twrp-x.x.x-x-umts_spyder.img and rename it to recovery.img.
   warning

   Important: Other recoveries may not work for installation or updates. We strongly recommend to use the one linked above!
2. Connect your device to your PC via USB if it isn’t already.
3. If your device isn’t already in fastboot mode, on the computer, open a command prompt (on Windows) or terminal (on Linux or macOS) window, and type:

   adb -d reboot bootloader
   

   You can also boot into fastboot mode via a key combination:

   • With the device powered off, hold Volume Up + Volume Down + Power.
4. Once the device is in fastboot mode, verify your PC finds it by typing:

   fastboot devices
   

   If you don’t get any output or an error:

   • on Windows: make sure the device appears in the device manager without a triangle. Try other drivers until the command above works!
   • on Linux or macOS: If you see no permissions fastboot try running fastboot as root. When the output is empty, check your USB cable (preferably use a USB Type-A 2.0 one or a USB hub) and port!
   check

   Tip: Some devices have buggy USB support while in bootloader mode, if you see fastboot hanging with no output when using commands such as fastboot getvar ..., fastboot boot ..., fastboot flash ... you may want to try a different USB port (preferably a USB Type-A 2.0 one) or a USB hub.
5. Flash recovery onto your device:

   fastboot flash recovery recovery.img
   

6. Now reboot into recovery to verify the installation. Do not reboot into the existing OS, since it will overwrite the recovery you just installed!

   • With the device powered off, hold Power. At the SafeStrap splash screen press Menu within 10 seconds.

     info_outline

     Note: If you can’t power down the device, try long-pressing the key-combination (if any was used in the instructions above) until the device reboots and follow the instructions above

Installing LineageOS from recovery

1. Build a LineageOS installation package.
2. If you are not in recovery, reboot into recovery:
   • With the device powered off, hold Power. At the SafeStrap splash screen press Menu within 10 seconds.
3. Now tap Wipe.
4. Now tap Format Data and continue with the formatting process. This will remove encryption and delete all files stored in the internal storage.
5. Return to the previous menu and tap Advanced Wipe, then select the Cache and System partitions and then Swipe to Wipe.
6. Sideload the LineageOS .zip package:
   • On the device, select “Advanced”, “ADB Sideload”, then swipe to begin sideload.
   • On the host machine, sideload the package using: adb -d sideload filename.zip.
     check

     Tip: Normally, adb will report Total xfer: 1.00x, but in some cases, even if the process succeeds the output will stop at 47% and report adb: failed to read command: Success. In some cases it will report adb: failed to read command: No error or adb: failed to read command: Undefined error: 0 which is also fine.

Installing Add-Ons

1. Repeat the sideload steps above for all desired packages in sequence.

All set!

Once you have installed everything successfully, you can now reboot your device into the OS for the first time!

• Run adb -d reboot.
