A lot of people asked for lolypop rom for DG550. Here it is. Rom is very good for those who don't need gps.
So please do not coment GPS is not working, it's a CM12.1 bug and we are waiting for fix, also with the microphone bug and sync bug (turn of gps)
GPS, Sound Recorder Can not access to microphone (Set format to “WAV”)
USSD (Is only working for some carriers) & Hotspot
BACKUP YOUR ROM FIRST
1. Place downloaded rom zip into root of sd.
2. wipe data, cache , dalvik cache (factory reset)
3. flash rom and gapps
