OK so I just got my moto x and rooted unlocked the boot loader and have twrp installed. Its a Dev edition from Verizon and I haven't accepted any updates yet because I've skimmed threads and know I won't be able to downgrade safely. I'm on 4.2.2 now and I want to get where I can install CM Pacman etc and most of these seem to run on 4.4.2. I want to have a stock backup I can safely go back to so my question is before I install any new Roms do I now need to accept ota updates up to 4.4.2 then stop and backup or can I safely install CM now and still go back to my stock 4.2.2 backup? I apologize I know the answer is out there I just haven't been able to narrow my search criteria to my specific situation. Thank you
