To install it you need a Custom Recovery installed on your devivce and also your phone must be rooted. This guide is only for Xperia Z2 D6503. So before starting the flashing procedure be sure that your phone is the same like the phone mentioned here. To view phone model number go to Settings > About Device and check the model number of your phone. Flashing this ROM in other device may result in bricking it.


  • Battery should be at least charged up to 70% so you will be sure that your device won’t go dead during the flashing procedure. If it goes down may cause software brick and you have to install stock ROM and wipe the data as well.
  • Flash a custom recovery, you can install either TWRP or CWM. It is suggested to install TWRP custom recovery in this case. So be sure to install it and not CWM.
