[Make A Complete Backup”]Before proceeding, make sure to take a complete backup of your device.

  2. Reboot your device into TWRP Recovery:
    • Power Down your OnePlus One.
    • After the phone is completely switched off – Press and Hold the Power Button and Volume Down Buttons at the Same Time.
    • Continue Holding these two buttons past the OnePlus/Android Splash Screen that appears.
    • When the phone boots into Recovery Mode, release the power and volume down buttons.
  3. Completely wipe System/Data/Cache/Dalvik. To do this, select Wipe > Advanced Wipe and then select the above-mentioned things and select ‘Swipe to wipe‘.
  4. Go back to the TWRP home screen, tap on ‘Install’ from the available options. You will be asked to choose a file to flash/install. Browse and select the downloaded file and then ‘Swipe to install.’
  5. After the ROM installation completes, go to TWRP main screen and select ‘Install’ again and flash the downloaded GAPPS package.
  6. Once the installation is complete, reboot your device.
[In case of oppo.verify_trustzone error”]
  • If this happens, then first you must install/use TWRP recovery 3.0.2-0. Next, download and flash the latest official CM13.0 snapshot.
  • Then, without rebooting from recovery, wipe /system and flash my ROM.
  • This process is necessary to update various firmwares (including TrustZone), as the updated firmware is needed by this ROM.
  • After flashing this ROM, flash a Google Apps package, and then reboot.

For updating to a new version:

If you are already running this ROM, then you can update to a newer version of the ROM via the built-in OTA updater or by simply dirty-flashing the new ROM build without wiping anything. But, Do NOT reinstall the GAPPS.

Miscellaneous Tweaks

In this ROM, the CPU is underclocked as the developer thinks it is better for the device’s performance. But, if you want to restore to the actual clock speed, you can simply flash the below zip file in TWRP recovery:

Disable CPU Underclock
