How to Update Motorola RAZR M XT907 to Android 5.1 Lollipop
Step 2: Connect your Droid Razr HD XT925 to your computer to transfer the download zip files to your phone SD card. [Make sure latest Motorola drivers are installed, otherwise your PC won’t recognize your phone]
Step 3: Turn Off your phone and boot it to recovery mode. [You can’t use touch in recovery mode, so use Volume Up and Down buttons for navigation and Power button for selection]
Step 4: In recovery mode, first tap on “wipe data factory reset” option to perform a factory reset. Once this is completed, go to advanced options and select “wipe the cache” followed by “dalvik cache” options to clear the cache.
Step 5: Go back to main recovery menu and select “Install zip from sd card” followed by “choose zip from SD card” and select the ROM zip file you have transferred to SD card in Step 1. Once ROM flashing is completed, repeat the same step for GAPPS.
Step 6: Repeat the above step for Google Apps (GAPPS) installation.
Step 7: Once the installation is completed, go back to main recovery menu by selecting “+++++Go Back+++++” option and reboot your phone by choosing “reboot system now” option from main menu. For the first time, your phone might take little more time than it usually takes, so don’t be panic as it is normal and will be only for 1st time.
Voila. Now you have installed the CM12.1 Android 5.1 Lollipop custom ROM on Droid Razr HD XT925.
