So I won't have troubles with GPT stuff if I do this? Can I go straight from 4.4.4 to this? Going back to 4.4.4 is possible too right?Here is twrp backup of 5.1 . I upload it that you don't mess your boot loader and modem.
Works perfect with my xt1052
Use TWRP 126.96.36.199 and restore system and boot
Erase data cache and dalvik cache
Well us vzw moto x are still on 4.4.4when I can use all moto x firmwares without touch modem and boot loader in my xt1052 you can use them too. I'm using every 5.0/5.1 otas without touch my boot loader because I modify them to upgrade only system and boot. Not more..
The backup is only system and boot. so you will able downgrade to everything. Just backup your original firmware to be sure.
Just the nexus player got it tho´. And they are just some minor security, call sounds fixes soooo no problem here]We are behind on versions again 5.1.1 just dropped lol
