  • If you are rooted, you might temporarily loose root access, but it can be restored later, so do not worry.
  • Create backup of all the data and apps on the phone, as they might get lost in the procedure.
  • Also you will need a micro SD card, in which we will be placing the update files.
  • Also charge your phone upto 50% before updating Droid Razr to Jelly bean, so that the phone does not switch off in the midst of the process.

  • Follow all the steps carefully, and make sure the device model is the same. As this tutorial won’t work with any other phone except Droid Razr XT912.
