Hey everyone,
Update: Open Beta build has been postponed due to failing internal QA, it will be released as soon as the QA issues have been addressed

Please note:
- If you have already flashed an Open Beta (you are currently running the latest Open Beta), you will receive this new build as an OTA.
- If you are not running open beta software and would like to, please refer to the flashing instructions and the full ROM on the downloads page here.
- 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.
- Moving 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).
Make sure to let us know how you feel about the beta builds here in the thread too. We are watching.
Never Settle.

WARNING! Open Beta releases are for competent and experienced users since they may not always be stable and are for the purposes of testing and reporting to OnePlus via, "feedback", to help them develop future stock firmware and features. By installing this Open Beta, you accept the potential risks. Once on the Open Beta pathway you will no longer receive the regular OnePlus, Official Stable OTA's and you may need to wipe your phone, (data and cache), before attempting to return to Official Stable OnePlus stock firmware.

This explains the Open Beta schedule and how to report bugs and issues...
OxygenOS Beta Program: Explained.
LEAVING OPEN BETA
Please read these instructions carefully and thoroughly
If, for any reason, you wish to leave the Open Beta programme and return to the OnePlus stock, stable OxygenOS releases, this will entail either contacting OnePlus Support...
https://www.oneplus.com/uk/support/contact
... or you can download the latest stable OxygenOS firmware from the official OnePlus Downloads & Updates store and providing that the current stable OxygenOS release date is of a later date than your installed Open Beta, install it using your phone's, "Local upgrade", by following the, "How to upgrade system?", instructions on the download page. Ensure that the downloaded update file is placed in the phone's storage and NOT in a file otherwise, "Local upgrade", will not see it.
Should you receive the following message whilst attempting to install the stable OxygenOS update... "Local upgrade The version of your selected package is lower than that of the current system. To avoid failure when booting up, downgrading is not allowed."... it means that the update you are installing is older than your Open Beta... wait for a newer release of OxygenOS stable or use one of the following methods.
Note: This method may erase all the contents of the phone, please be sure to backup first.
Alternatively, you can also use the, "roll-back" firmwares for the OnePlus 6 and OnePlus 6T/McLaren, originally issued for downgrading from Android Q Beta, which are flashed in Local upgrade. These will require a wipe of your phone, (data and cache). See towards the bottom of the following post in the next link to download the, "roll-back", firmware that is applicable to your model of phone, 6T/McLaren or 6...
Download Roll-back packages for OnePlus 6T/McLaren & OnePlus 6
Watch the following video, carefully and thoroughly, as it will answer all your questions on how to use the roll-back firmware to go back to stock OxygenOS on Android Pie...

Downgrade from Android Q or Open Beta to Android Pie Oneplus 6T/McLaren & 6
Note: This downgrade method will erase all the contents of the phone, please be sure to backup first.
Also available, for competent and experienced users, there is the OnePlus tool for the 6T, McLaren and 6. Just head over to the xda developers forum by following these links...
OnePlus 6T MsmDownloadTool v4.0.59 (OOS v9.0.13) 6T Global & McLaren models
OnePlus 6 MsmDownloadTool V4.0 6 Global model
See a YouTube video for this process.
Note: This downgrade method will erase all the contents of the phone, please be sure to backup first.
(If you have any questions regarding the use of the MsmDownloadTool, please ask them on the xda developers forum and do not clog up the Open Beta thread)
Custom Recovery. Users that have installed a custom recovery such as TWRP, can use this to revert to stock on the OnePlus 6/6T. Refer to your relevant custom recovery developer for ways to do this.
If you have the McLaren OnePlus 6T you, "may", lose the McLaren Warp Charge animation/facility by flashing Open Beta firmware.
(N.B. Open Beta is not available for the non stock, 6T T-Mobile (USA) carrier minority variant firmware)
