Trying to figure this out as well, on my oneplus 7 pro and oneplus 6t I get the same issue, every time I install the stock rom through twrp after doing a factory reset if I reboot into system it'll reboot into twrp, or go into the apps rom im trying to flash away from, or if I reboot into twrp the data will be encrypted again and the only way I can get it in encrypted is by booting all the way back into the apps rom.
I've tried this on both devices with and without a pin, I've tried flashing the rom, selecting the opposite slot that I'm on and rebooted into recovery, it'll be encrypted again so I won't be able to flash onto the other slot.
I'm sort of at a loss and have been searching both forums relentlessly and have watched videos of people installing custom roms and they don't seem to be doing anything differently than I am. At this point the only thing I can do on both devices is use the msm tool to get back to stock every time I flash a custom rom.
Custom roms will flash, but I can't just reboot back into recovery or it'll be encrypted, I have to boot into the system, reboot back into the recovery and install the gapps and Magisk that way. Literally any advice would be appreciated.
Ive been asking around on the op7p forums but once I found out the 6t was doing the same exact thing I knew there's something I was missing, and since the 6t has been around for a bit longer I hope one of you fine folks has an answer to my a/b slot woes.
I'm in the same boat right now with my OP6 on a custom rom, what did you end up doing? TWRP isn't working for me and I keep getting the encrypting problem. Did you just use the fastboot method?
