Unofficial TWRP for Oppo A91 (CPH2021) running Android 11.
This recovery works also on the Oppo F15 (CPH2001) as it's a rebranded A91.
IMPORTANT it appears that recovery does not work on the PCPM00 model.

Since this phone has fastboot disabled it is necessary to use alternative tools. I recommend using MTKClient.
Just unzip the file and flash the TWRP to the recovery partition.
Use the minimal manifest twrp aosp 11 here
