Owners of Motorola Droid RAZR XT910 may now install the latest Android 4.2.2 Jelly Bean update even without the official firmware yet. This is made possible with the use of a custom ROM called LiquidSmooth ROM, an unofficial firmware available for users to download.
While it is not the official firmware, the Droid RAZR XT910 is so far proven capable of running the latest Android 4.2.2 Jelly Bean smoothly. If you want to update your Motorola Droid RAZR XT910 to Android 4.2.2 Jelly Bean now, then you may follow these steps.
Back up all your files before you begin with the installation process. Do this to ensure you have everything you need to recover if things go wrong later on. Among the most important files to back up are SMS & Call Log, Contacts & Settings, Images, Songs, Videos, Files, APN and MMS Settings and WhatsApp Manager.
Also note that this guide is only applicable for Droid RAZR XT910 model, thus should not be tried on any other Android device. To make sure you have the right device model to update, check your handset’s Settings–>About phone.
1. SECURE all necessary files.
In this case you would need to download the zip file for LiquidSmooth ROM 4.2.2 Bean ROM for Droid RAZR XT910. Filename would be: Liquid-JB-v2.1-RC1-umts_spyder.zip.
You also need to download Google Apps zip filename: gapps-jb-20121212-signed.zip.
2. After downloading both files, connect your Motorola smartphone to the PC with a USB cable.
3. Copy the files you’ve downloaded to the SD card of your smartphone but DO NOT extract any of these files.
4. Disconnect the USB cable from both devices.
5. Turn your Android smartphone off. Leave it off for around 30 secs or a minute.
6. Boot into Safestrap recovery.
Do this by pressing the power button to turn your smartphone on. When the Motorola splash screen appears, you will be prompted with the Safestrap screen, showing Safetrap Disabled in red, Recovery at the bottom-left and Continue option at the bottom right.
7. On the Safestrap main screen, tap on the Recovery button. This will let you boot into Safestrap recovery mode.
8. Set up a ROM slot for LiquidSmooth.
a. Do this by tapping on Boot Options and it will prompt you with a new screen.
b. Tap on the ROM-Slot-1 option.
c. Set the data partition to at least 1GB (unless you are planning to install more apps and games). Wait for the partitions to get set up. (Note) System and Cache partitions are default, thus can’t be modified. The ROM slot should be ready then.
9. Once the ROM slot is all set, the device will boot from the new slot from now on. Install the LiquidSmooth ROM on that slot.
10. Press the home button to go back to the main screen.
11. Tap on Install.
12. Look for and select Liquid-JB-v2.1-RC1-umts_spyder.zip. You will be prompted with the next screen.
13. On this screen, slide the button to confirm the installation. The LiquidSmooth installation should then start.
14. Wait until the installation process is done. Once completed, repeat step 10 to 11.
15. Look for and select gapps-jb-20121212-signed.zip to install the Google app package. Confirm the installation by sliding the button.
16. Wait for the installation process to finish.
Once done, return to the main menu and select reboot system. Doing so will let your smartphone boot up into the customized Android 4.2.2 Jelly Bean ROM LiquidSmooth.
It may take time for the first reboot to complete. This means you have to wait until its done and get going.
Be sure to spare at least 80 percent battery power on your device to avoid installation disruptions. Once the device shuts off in the middle of the installation process, a hard brick could occur on your device.
Also, you have to install a USB Driver for Droid RAZR in your PC. The USB Debugging should also be enabled for you to transfer file from PC to mobile (vice versa). Lastly, make sure your smartphone is rooted with a Safestrap Recovery installed.
