So I want to change from concept 6.0.1 software to official cm 5.1.1, now maintained by @nailyk. I am on locked bootloader, also been reading your posts and 5.1.1. with january patch seems like the software for me (need daily driver with security patch, also a fan of encryption). I am a little scared thou since I need to back up DRM and unlock bootloader. My question is now when I unlock BL how do i flash this TWRP, and then 5.1.1, did not really understand from original post, and some links are not working?
