    Any clue how can I get TWRP to an unrooted x12 R19? I have gone through like 10 different walkthroughs to achieve that, but no success at all. I believe the only thing I was successful at was to unlock bootloader, but nothing else. :(

    So, after setting it all up there's two positive things and two negatives. 

    + finally I got LTE working at full speed (impossible with stock rom, at least for me)
    + the rom is superfast. I use s–tload of apps and still it's very fast

    - can't get contacts sync to work and gmail app doesn't work either (possibly could be fixed with updated gapps)
    - i just received a call and the other side could not hear me while I heard them clearly

    Any suggestions, please?

    tried 3 different gapps and nothing seems to work. Let's hope you'll be luckier. I am so looking forward to the fix

    Thanks for the Update.

    Calender Sync works fine.:)

    But the syncing with google contacts doesn't work.

    I've tried to install the actual open_gapps-arm-5.1-nano but it doesn't install, because ther isn't enough space.


    Can you check the Contact-sync with you GAPPs?
