Your device is corrupt and it can't be trusted and will not boot up.

    I actually flashed the reserruction remix rom with Android 10 hotdogb on my OP 7T. I used the Playload dumper to flash this rom as TWRP was not able to detect the ROM or memory of the device. After flashing Rom was working fine but I decided to pull back and unroot. Now, when I flashed the Stock rom it booted up with no error. Then once I try to lock the bootloader, it gives me the corrupt error and does not boot. Then I have to again unlock bootloader to gain access to OS.
    At this point, I thought that there would be an issue with the flashing, so I re-flashed, bur the issue persist.
    So, now currently I am using the stock OS (flash through Flash-all bin) with an unlock bootloader.
    If you can help me what exactly can be done further to overcome this error, it would be at great help.

    Thank you so much for the response. This gives me a relief that it is possible. I'll perform the steps in a week as travelling. Will keep it posted. Thanks!!

    I successfully re-locked the bootloader over fastboot. It was my OnePlus 6.

    Maybe you had to flash OxygenOS twice. So that Slot A and B has OOS.
    Resurrection Remix on one Slot may caused the problem.

    Idk about OP6 but 7T can't be locked by fastboot using lock command
