Notes:

• Hold down Volume Up + Power (for waaaay longer than you'd expect) to force full power off.
• Hold Volume Up + Volume Down while connecting USB-C to enter QDLoader mode

Interesting. I'm trying to flash OxygenOS to my ACE2. How did you check which partitions should be flashed? I have extracted the payload.bin and found many img files. Not sure which one to flash.
