[OnePlus 5T  ROMs, Kernels, Recoveries, & Other Dev] shirtsofbamboo:
I had to mess with a good thing. I have a OnePlus 5t. I saw that Xposed is in beta for Magisk, so I installed it. Rebooted to activate an Xposed module, and the phone boots and then shuts down and reboots to TWRP recovery. I'm running blu TWRP 3.2.1-1, which prompts for the pattern but it doesn't work. I also tried twrp-3.2.1-0-universal-codeworkx-dumpling.img, which does the same thing, and twrp-3.2.1-0-dumpling.img which doesn't seem to know anything about encryption. And I can't mount /data in recovery now, so I can't uninstall Xposed or Magisk. Has anyone come across something like this? I had even done a nandroid backup, but that is stored on the encrypted partition, so it doesn't do me any good.

Help me Obi Wan
