First of all, very appreciate for making this ROM so that we can experience the latest Android version. This ROM is very awesome!
However, after a few weeks' try , i want to get the features of the official ROM back. Thus i intent to use the flashtool to flash the official firmware back .But after i successfully flash the firmware of Lolipop5.1.1, It stop booting for freezing at the bootanimation. the same situation happened when i flash the official based rom.
I spent almost 2hours to seach this thread to look for the solution, and i found that someone gets the same problem ,however, without solved. This may be a common problem for the one who flash this cm14.1.
I sincerely hope that @Chippa_a can give us a proper solution since we have choice to select other ROMs , but not a single ROM of cm14.1 for the whole life of our phone . Thank a lot !
I solved it!!! install stock rom 4.4.4 with Flashtool, i use this : https://docs.google.com/file/d/0B_0uKEUjkKBfOGEzcFg2djZFUU0/edit
Finally start without problems and i can from there install again Lollipop and other based stock roms....
