Recently rooted my 9 Pro, been trying to reset to stock. Get a device corrupted error if I try to relock the bootloader. And the OS I used is from One Plus website. OTA update doesn't work either. Any idea if Oxygen updater will fix it and when they'll get 11.2.8.8 ?
You need to flash stock boot image in fastboot. There is a thread with 7.7 boot image here at top of thread. Once you do that you should be able to lock which will wipe your device or just wipe without locking. That should get you to 💯 stock.

For me everything goes very good, like i did before.
European model, european os.

Yes I'm facing same issue. Everything seems fine except I cannot click power button to lock screen, or take screenshots. Rebooted several times. Rooted, but never faced issue like this bcux of that.

Sorry to hear that, I can remember a while back on the 8 pro and a few Pixels, it seemed like every time or just about every time I updated, I'd have to wipe my device for one reason or another. Now if that doesn't fix it then I guess it would be custom ROM time.

I updated 2nd slot to see if that helped.. Didn't.. But I figured out why.. Not sure why but the awesome DE-Throttling mod the guy from other thread created was causing the problem..for me anyway. I deactivated that and power button is back to normal.

For those curious about throttling in this update, it's still present:

    Can you please explain to mw what is a throttling?

    Oneplus, in their infinite wisdom, decided to throttle (scale back the performance) of the processor when certain apps were used, not allowing the app to take full advantage of the processing power. This can cause delays, lag, or general slowness of said apps. If I remember correctly (I may not) there's something like 300 apps that Oneplus throttles.

    Not only did they do this, but they tried to hide it, too.

    If the Pixel 6 is a good phone, I'll be jumping ship. I've loved OP but this kind of crap (and no OIS on the OP9) infuriates me.

    Looks like they're rolling out 11.2.8.8 for the device : OxygenOS 11.2.8.8 for the OnePlus 9 and OnePlus 9 Pro - OnePlus Community

    Not seeing anywhere that it will get a full build, which is unfortunate since it's a PitA to update with an OTA when rooted and having a ton of mods.

    Edit:
