Nope, I wasn't talking about random reboots, but manual boots and boots by Magisk. But yes, I definitely selected the boot option when I flashed TWRP. And even if I messed it up once, I've flashed the latest (3.2.3?) and had clean flashed the latest build and was still experiencing this.
Currently restoring apps after clean flashing the 8/14 build. I'll post if it's any different.
EDIT: nope, still boots to stock recovery. TWRP is accessible as usually with home/up. But just a regular reboot sends me to the stock recovery with asks if you want to factory reset, turn on usb debugging, etc.
That's the exact thing I'm getting + I still have sim death on 8/14 clean install not sure what the problem is because im hearing that sim death and reboots should have been fixed.
