Warning: Do not flash partial update OTAs (under 1 GB) on a modified/rooted device! If you want to use partial OTAs, you must first flash the full OxygenOS zip that it applies to, and then flash the partial OTA from stock recovery. Flashing partial OTAs from TWRP will either fail or soft brick your device. You can return to a usable state by flashing a full zip in recovery.


Download the necessary files from the section above and follow the steps below:

Note: Dirty flashing is fine if you are running an old OxygenOS version or a ROM based on OxygenOS. If you are, however, coming from a Custom ROM, you must clean flash.

For Non-Rooted Users with a Locked Bootloader and Stock Recovery:

• Download the full zip/incremental OTA from the downloads section above and place it in the root of your internal memory
• Reboot to stock recovery > Shutdown device > Press Volume Down + Power buttons together
• Select language > Install menu > Install from internal > Select the full zip > Flash
• After a successful flash > Wipe cache
• Reboot

Note: First boot may take some time, so please be patient and wait for it to boot.

[Dirty Flash] For Users with an Unlocked Bootloader and TWRP Recovery coming from H2OS/OOS:

• Download the full ROM zip from the downloads section above
• Transfer the zip to the root of your device's internal storage
• Only needed if you are using a TWRP that does not ignore the compatibility.zip check: Remove the compatibility.zip from the downloaded full ROM zip with either MiXplorer or Total Commander (not with any other tool!) on your device itself
• Reboot to TWRP and take a nandroid backup of your existing ROM
• Flash Magisk Uninstaller (recommended)
• From the TWRP menu, Wipe > Advanced wipe > Select dalvik-cache and cache > Swipe to wipe
• From the TWRP menu, Install > Select full ROM zip > Swipe to flash
• Flash the latest stable Magisk in case you want to root
• From the TWRP menu, Wipe > Advanced wipe > Select dalvik-cache and cache > Swipe to wipe
• If you were decrypted earlier, flash xXx No Verity 4.0.zip from here
• Reboot

Note: First boot may take some time, so please be patient and wait for it to boot.

Warning: Dirty flashing (update) can be risky! Remember that if you face issues after dirty flashing, you will have to clean flash.

[Clean Flash] For Users with an Unlocked Bootloader and TWRP Recovery:

• Download the full ROM zip from the downloads section above
• Transfer the zip to the root of your device's internal storage
• Only needed if you are using a TWRP that does not ignore the compatibility.zip check: Remove the compatibility.zip from the downloaded full ROM zip with either MiXplorer or Total Commander (not with any other tool!) on your device itself
• Reboot to TWRP and take a nandroid backup of your existing ROM
• Flash Magisk Uninstaller (recommended)
• From the TWRP menu, Wipe > Advanced wipe > Select dalvik-cache, cache, system, vendor and data> Swipe to wipe
• From the TWRP menu, Install > Select full ROM zip (modified one with compatibility.zip removed, in case you're on Oreo or unmodified one, in case you're on Pie) > Swipe to flash
• Flash the latest stable Magisk in case you want to root
• From the TWRP menu, Wipe > Advanced wipe > Select dalvik-cache and cache > Swipe to wipe
• Optional: If you wish to decrypt, format data via TWRP (please note that wiping the data partition, which we did in the 5th step above, is not the same as formatting it) and after that flash xXx No Verity 4.0.zip from here
• Reboot

Note: First boot may take some time, so please be patient and wait for it to boot.

Never Settle.

Some FAQ's on Android Pie Release

Q. Why is my brightness low after upgrading to Android Pie 9.0?

A: Google introduced new algorithm for the brightness which will give more control to the user specially in darker environments. The user have to train the brightness preferences for some time in different lighting conditions they use their device so that the device learns it and then adjusts the brightness automatically after that.

Q. Where is clear Cache in Android Pie?

A: Cache partition no longer is available on Pie. So there is no option for clearing it. One has to clear cache by individual app now.

Q. Why is there no Digital Well-Being available in OnePlus device running Pie?

A: Digital Wellbeing is currently available only to Pixel devices and Nokia 7 Plus. This may change in near future and OnePlus may be added to its supported device list.

Q.Why is "X" app crashing in my phone running Android Pie?

A: Many apps are still not updated to support Android Pie, that is the reason they are not able to run in the new OS. Contacting the app developer will be much more helpful.

Q. I downgraded to stable channel, but did not receive the update to Pie, why?

A: The wide-rollout has begun, its only matter of time, you will get the notification for the new update.

Q. Why is my battery draining so fast after update?

A: This is a major upgrade, you should give it some time to settle before the battery starts working normally. Also battery calibration is always a good way to get most out of it.

Q. I do not like the new Recents layout, what can i do?

A: Unfortunately, nothing can be done about it. Its how Google designed it.

Q. I cannot activate the new Pill gestures, why?

A: Sometimes update messes up app data and settings. To solve this clear OnePlus Launcher data and reboot the device.

Q. My Play Store is showing "uncertified" after i downgraded to stable, how can i solve it?

A: Clear Google Play Services data and Play store data and Reboot. Let Play store update automatically and it should change the status to Certified.

Q. Why cannot i use volume buttons to control the ringtone volume in Android Pie?

A. Google has made change to it, now we can change media volume by default. OnePlus has provided a shortcut to directly go into settings to make it easier to change the ringtone volume.

Q. Why my Fingerprint does not work, after my phone is in standby for long time?

A: The Fingerprint service goes to sleep and thus doesn't allow unlocking the phone.
To avoid this, the current work-around it to turn Off Standby Optimization in Advanced Optimization Battery Settings or wake up the phone using Power button after long standby.

Q. Why does not my screen light-up on incoming calls?

A: This happens when the Phone app settings is messed up.
To solve this:
Touch and hold on Phone app and Tap on App Info.
Now tap on Notifications and then tap on Incoming Calls(Not the Checkbox).
Select Behavior and make sure its set to Make Sound and Popup on Screen
This should allow the incoming calls to notify you lighting up the screen.

Q. My clock shows alarm notification 2-hrs prior to actual alarm/ my alarm is missing, what can i do?

A: You can follow the steps below to fix it:
Go to Settings>Apps & notifications>Display all apps>Clock>Notifications.
Now, there are 2 things to do :
a) Press on "Clock" (Not the Checkbox)>Behaviour
Choose "Silent display" : this way you won't have the sound notification 2 hours before schedule

b) Press on "Alarm" (Not the Checkbox)>Behaviour
Choose "Sound alert and display on screen" : If you choose another option, the screen won't turn on when the alarm rings. And you also want to set the sound alert to none. Otherwise, when the alarm rings, you'll also hear the notification sound.

Q. Why is my slow-mo videos stuttering?

A: It seems to be a known bug currently. Developers are aware of the bug and are working on it. The fix could be released in future update.

Please go through this Q&A before making any bug reports and attach the logs with the reports.

Thank you :good:

Do we need to Full Wipe or is it OTA?

Click to expand...

Click to collapse

Won't be an OTA you need to manually flash it by downloading the full zip. Both stock recovery or twrp can be used for it. I will update the instructions once the build is out along with the changelog

Please keep in mind that this is beta software. These builds are sometime NOT as stable as our official OTAs generally are. By installing this update, you accept the potential risks of data loss.

Once you migrate to the Beta path, you will continue to receive Open Beta OTAs. You will NO LONGER receive the regular Official Stable OTAs.

Reverting back to the Official OTA path from the Beta path will require a full install and clean flash (FULL WIPE of all data and cache).
