I have the T-Mobile branded version so when I MSM I have to start with the conversion to global every time - which is OOS 9.@theslam08 From which version of OxygenOS did you came ? How did you flashed CrDroid 9 ?
I can try to upgrade the stock Oneplus 7 pro with official updates and Oxygen updater, then flash the firmware and retry Crdroid 9.
Then I go through the OTA for each Android version, OOS 10, OOS 10 again, then OOS 11.0.9. I stop there and bootloader unlock. I think OTA is better than just flashing straight to A11, but I could be wrong and may make no difference.
Then I just flash the firmware file (provided in this ROM OP) for A12 and proceed from there - just like your instructions you just posted earlier.
