2. Charge your device so it has at least over 60 percent battery. This is to prevent you from running out of power before flashing process completes.

3. Back up the following: (to Update To Official Android 5.1.1)

   • Call logs
   • SMS messages
   • Contacts
   • Media – copy files manually to a PC/laptop
4. Enable the device’s USB debugging mode. First, go Settings>Developer Options>USB debugging.  If Developer Options is not there, go to About Device and look for Build Number.  Tap the build number seven times and then go back to Settings.  Developer options should now be activated.
5. Install and setup Sony Flashtool. Open Flashtool>Drivers>Flashtool-drivers.exe.  Install the following drivers:
   • Flashtool
   • Fastboot
   • Xperia M2 Dual
6. Have an original OEM data cable that you can use to make the connection between the device and a PC or laptop.

Note: The methods needed to flash custom recoveries, roms and to root your phone can result in bricking your device.  Rooting your device will also void the warranty and it will no longer be eligible for free device services from manufacturers or warranty providers.  Be responsible and keep these in mind before you decide to proceed on your own responsibility.  In case a mishap occurs, we or the device manufacturers should never be held responsible.
