Do not continue after something fails!
Before you start, make sure you’ve deleted every Google account from the device on a fresh install. This will prevent “Factory Reset Protection” (FRP) from kicking in during the setup steps.
Installation is only possible on a device with unlocked bootloader!

Flashing instructions
Pre-installation:
- Make sure you have the ROM zip, latest OxygenOS firmware and recovery images.
- Download copy-partitions-20220613-signed.zip if you are on CPH246x.15.0.0.1600 or newer firmware.
- GApps package (optional) (from download page, GApps button).
WARNING: If you are on CPH246x.15.0.0.1600 or newer firmware, you MUST flash copy-partitions-20220613-signed.zip before installing the ROM. Skipping this step will result in an installation failure and may leave the device hard-bricked, requiring EDL recovery. Do not proceed without completing this step.
First time installation (clean flash):
-
Go to bootloader (adb reboot bootloader).
-
Flash the required images:
fastboot flash boot boot.img fastboot flash dtbo dtbo.img fastboot flash vendor_boot vendor_boot.img fastboot flash vbmeta vbmeta.img -
Reboot to recovery (fastboot reboot recovery).
-
Format data.
-
Go to Apply Update → Apply from ADB.
-
If you are on CPH246x.15.0.0.1600 or newer firmware, sideload copy-partitions-20220613-signed.zip:
adb sideload copy-partitions-20220613-signed.zip -
Once completed, reboot back to recovery.
-
Go to Apply Update → Apply from ADB again.
-
Sideload the ROM zip:
adb sideload rom.zip -
Get a coffee while it's installing.
-
After installation, if you want GApps, reboot to recovery again and sideload gapps.zip like the ROM zip.
-
After all, reboot the system.
-
And you got it!

- Reboot to recovery.

Via OTA:
