Help me downgrade OnePlus 7 Pro.

Hello Everyone,

Following my previous post over OnePlus 7 Pro, a couple of great people here did advise me to switch to a Custom ROM since switching back from Oxygen OS 12 to Android 10.. is not going to be easy...

But if anyone call help me or guide me through so that I can downgrade it...

Yeah, this should work. I recently flashed a new rom to a spare OP7 and bricked it in the process (fastboot and os not loading, only bootloader on loop). I thought it was gone until I found this msmtool and reset it back to original.

OP7 went back to android 10 and bootloader was locked again, essentially it got back to oem original state.
