Prepare your phone

  1. This guide is only for use with a Sony M5 Dual D5633, D5663 and D5643. If you use this guide with other devices you could end up with a bricked device.  Check your device’s model number by going to Settings>About Device.
  2. Charge your battery to at least over 60 percent to prevent you from running out of power before process is done.
  3. Back up your important contacts, SMS messages and call logs. Back up any of your important media files by copying them to a PC or Laptop.
  4. Enable your device’s USB debugging mode. You can do so by going to Settings> Developer Options> USB debugging.  If you don’t find developer options in settings, activate them by going to Settings>About Device and looking for your build number.  Tap the build number 7 times.  Go back to settings; developer options should now be available.
  5. Install and setup Sony Flashtool on your device. After installing, open the Flashtool folder.  Open Flashtool> Drivers> Flashtool-drivers.exe.  Install: Flashtool, Fastbood and Xperia M5 Dual drivers.
  6. Have an OEM data cable to make the connection between your device and your PC

 

 

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.
