[HTC 10 Questions & Answers] cykocator:
Hi,

Previously I had a working version 2.41.401.41 with Magisk. I wanted to remove root and via twrp I applied a unmodified TWRP backup of 2.41.401.41.

But since my HTC 10 has bootloop. I tried to install customs ROMs and differnet version of RUU and TWRP backups and I still have the bootloop.
