As title says I've tried in each and every way, both scrubbers port and hybrid ROM and I keep getting update failed, I have done full wipes and used twrp, cwm, philz, tried from stock ROM from 4.4 ROMs 5.0.2 ROMs, flashed system & boot via both flash tools before and after flashing rom and still nothing... Anybody have any tips fixes or any othwr solutions???!
I am currently on crdroid rom (obviously unlocked BL)
