Here is Cyanogenmod 12.1 backup for SM-G531H. It is just test version and it has list of issues:
- wi-fi doesn't work (don't turn on)
- RIL doesn't work (you can send requests, but no callings)
- audio doesn't work
- if wipe dalvik cache then you will got bootloop
- memory (internal storage and sdcard mounts and works)
- both cameras
I hope there are found peoples who can help me to fix all of this issues.
To install download archive from link and unzip it to sdcard, then go to TWRP Recovery and restore it. Don't forget to make backup of your system.
