You can dirty upgrade(boot to twrp, clean dalvik and cahe, install,clean cache, install Gapps recomended by dungphp, clean cache, reboot).
I never backup my rom, i only backup apps, that's why i don't wanna try it without some reviews.
Thank you for your effort.
Hello,
Thanks for the instructions, i just installed the rom succesfully. Only my homescreens seem to be missing.
So far the rom looks like it's an improvement from 4.6. The vibrations seem to be working again and the screen hasn't done any on/off flashing so far. If i encounter any problems while using it during the day tomorrow i'll post an update. If i post nothing then it should be good.
