Hi,
I am a new in android. However I couldn't help flashing cm 12.1 on my device. I downloaded it from xda(http://forum.xda-developers.com/gala...d2-sm-t2949693). I also followed the steps properly and I have all the pre-requisites. But when I start flashing the rom using CWM Recovery, it says :
"THIS PACKAGE IS FOR DEVICE: ms013g; THIS DEVICE IS ms103.g
E : ERROR in /data/media/0/ cm-11-20141227-UNOFFICIAL-ms013g.zipcm-11-20141227-UNOFFICIAL[COLOR="Red"]-ms013g.zip(status 7)
Installation abborted"
So i failed to flash it and as I did wipe data, wipe cache partition and others. can't boot into the device.
I also googled in search of cm12.1 for ms 103.g device, but failed.
Now how can I flash cm 12.1 or 12 or 11(i tried all of them) on my phone.
N.B: My device model and other infos on the back are :
MODEl : SM-G7102
FCC ID : A3LSMG7102
SSn : -G7102GSMH
MADE IN VIETNAM BY SAMSUNG
IMEI : 359908/05/994292/5
359907/05/994292/3
Somebody please help. I am stuck.
