    Hello folks, this thread is in specific to flash Stock ROM onto OnePlus 7T variant. Below steps can be used to rollback your OnePlus 7T variant to a previous release of OOS.

    In the earlier version of OOS, adb sideload command could be used to flash stock ROM in recovery mode, with the current ( April,2020) recovery mode of OnePlus 7T there isn't no option for the adb sideload command.

    Below steps can be used to flash Stock ROM onto OnePlus 7T variant.

    Download the required variant version from the below link.
    https://forum.xda-developers.com/oneplus-7t/how-to/op7t-unbrick-tool-to-restore-device-to-t3994835


    Unzip the file, and you will find the firmware and MSMDownload tool to flash the file.

    Next, unlock the Boot loader, this is required for the device to enter the EDL mode (The phone must be on, unlocked, and USB debugging turned on so that you’re able to send and receive ADB commands to the phone).

    Once Bootloader is unlocked, to enter to EDL mode, execute the command “adb reboot edl” over the command line and the phone will reboot into EDL mode ( You can have the device in switched on state to enter EDL mode).

    The phone stay's in EDL mode only for couple of seconds, so in matter of time you would need to execute the MSMDownloadtool to start flashing the Phone.

    To flash the firmware, follow the below steps:
    1)Launch MsmDownloadTool <version>.exe
    2)Click on Target Button in MsmDownloadTool
    3)Select O2 (for global firmware) or INDIA
    4) execute adb reboot edl
    5) When the device reboot's and screen goes blank, click START in MsmDownloadTool

    Note, do not make any changes in upgrade mode.

    Wait for >400 sec

    Enjoy the flashed firmware.

    I have referred below links for flashing the device and would like to thanks the authors.

    Just so I am on the same page. By following these steps, I can effectively make my 7T T-Mobile edition essentially become a non-Tmbile edition as if I bought this directly from the OnePlus store?

    Wouldn't suggest to flash the T-Mobile varient. If the same is locked to T-Mobile , it would require to unlock bootloader and flash a unlocked version of boot recovery and later flash the firmware. If at any point of mistake, the same would brick the device, would be hedious task to flash a stable OS.

    The XDA form has only unlocked version of international/Indian/European firmware.
