Can I use the OOS11 zip I already have to downgrade from OOS12 using the other slot? It's broken several things. I've only found a method that wipes the phone so far. Or maybe just flash Magisk to the unused (should be OOS11 since I just "updated") and reboot back to it?

first of all you should not ask your questions in 2 thread and create a 3 one. Thats simple spam.

Maybe, maybe not. Better exposure as not everyone is likely watching the one or the other.

Maybe a fair point. Figured better exposure. Never can tell if the right person (with a solution) is watching the whole board.

I have IN2023 and running official IN2023_11_C.15 ROM (received via OTA). I have 100% locked device. Which file should I use to revert it to the latest EU Android 11 ROM? Or should I wait for official rollback pack for my device?

Every Rollback Package i know will wipe your data.

So i suggest going the safe and easy way and use MSM tool.

OnePlus posted today on their forums the EU downgrade zip to 11.0.9.9 https://oxygenos.oneplus.net/OnePlus8ProOxygen_15.E.40_OTA_0400_all_2110091931_downgrade that you can use if you can't/don't want to use MSM tool , but you will need to add a .zip extension for it to be recognized by the OxygenOS 12 local update app.

OP will be updated later to add this zip to the index.

Thanks to all that support this thread. I accidentally flashed an 8T OOS version on my 8 Pro with the fastboot rom. Not good. It got stuck in bootloader mode. Thankfully I was still able to flash twrp and do an ADB side load of the 11.0.11.11 rom. I was back up and running shortly thereafter.

I just wanted to tell everyone that put this thread together thanks.

Hello, I don't know it this can be usefu, but here you can download the latest stable oos for op8 pro eu IN2023, based on android 12. I'm not sure, but it looks like that it has been retracted, since even though I downgraded to the android 11 stock, it doesn't find this update anymore

Just downgraded from OS 12 to OOS11.0.9.9.INAA on a IN2020

Just to be very sure - if I wish to be updated to the latest OS 11 version, i should perform a local upgrade with the following file found under Signed flashable zips>IN11AA Global?
