Installation Instructions

Step 1: Download the OTA update (TWRP flashable zip file) from above. If you are looking for root access after installation, then download the latest SuperSU package from the list.

Step 2: Transfer all the necessary files to you device’s internal storage or SDcard. Place the files where you can easily locate it.

Step 3: Now boot into TWRP recovery. To do so, turn off your device completely and then press and hold the power button and volume down key for a few seconds. Once you see the TWRP logo, that means you have successfully booted into the recovery. Alternatively, if you have rooted device, then use Android apps like the Quick boot or Boot Smart.

Step 4: Once into TWRP, take a Nandroid backup. To do so, tap Backup option and select all the partitions including the system, data, boot, recovery, EFS and cache(optional).

Step 5: Now return to the home screen again and tap Install option. Navigate to the ROM file from your internal storage and select it.

Step 6: Now swipe right on the confirmation action button below to install the ROM.

Step 7: Once installation completes, you can wipe the Dalvik cache or simply choose reboot to system option.

Step 8: Once you reboot, you should see the new boot logo. This means that the ROM has been installed successfully. First boot may take a while. If the system doesn’t boot or you come across boot loop, a factory reset from the recovery should do the trick. If that fails, you can restore your previous ROM from the TWRP recovery.
