How to update OnePlus 6 to latest Oxygen OS 5.1.9?

There are multiple ways to update OnePlus 6 to the latest OxygenOS firmware update. The first is to grab the full stock firmware zip from above and do a Local Upgrade.

Local Upgrade Method: Install full stock firmware zip

The Local Upgrade method is the easiest way to update any OnePlus device. This includes upgrading to Android 8.1 Oreo or even downgrading to a previous one. This can be used regardless of which Oxygen OS version your device is running. You can even install the alternative H2OS firmware onto OnePlus 6.

  • Download the latest available Oxygen OS full stock firmware zip from above.
  • Get the full firmware package from above for the OnePlus 6 and transfer the ROM file to the internal storage or phone storage. Place the zip file outside every folder. See the image below.
  • Now go to Settings app > visit System updates > tap on the top right settings icon > choose Local Upgrade option.
  • The Local Upgrade option will search for an upgrade package.
  • Once you see an upgrade package, tap over it and then hit the install option.

The device will automatically reboot and perform an upgrade. First boot may take a few minutes. If it doesn’t, you may want to perform a factory reset. However, doing so may result in loss of data.

OTA Update method: Install OTA zip

Secondly, you can capture the OTA update by going to Settings > System Updates > Check for OTA updates. Download OTA and install using stock recovery or ADB sideload method.

If you don’t see any action there, thwn using a VPN application such as SurfEasy Secure Android VPN can help. The OTA is usually live in regions of Germany and Canada. So download a VPN app and change the location to the countries above and check for OTA updates.

Root Method: Flash Oxygen OS ROM using TWRP

  • Make sure your device is rooted, with Unlocked Bootloader, and latest TWRP recovery insralled. Read: How to root OnePlus 6?
  • Download the latest Oxygen OS full firmware zip from above.
  • Transfer all the files to device storage.
  • Reboot into TWRP recovery.
  • Take a full Nandroid Backup.
  • If you are coming from official OxygenOS, you can also do a dirty flash. Meaning, without wiping anything.
  • However, if you have a custom ROM installed, is highly recommended to wipe the data, cache, and system first. So go to Wipe > Advanced wipe > and select partitions such as system, data, cache, etc. Do not wipe internal storage. Otherwise, do a factory reset from TWRP.
  • Flash the Oxygen OS  ROM zip.
  • Wipe cache and Dalvik cache.
  • Reboot to system.
