G935F and various problems
I changed Imei and repaired Network of all handsets after downgrade to 6.0 from 7.0.
One phone was OK and no error occured.
The other ones had no voice, lost Wifi and camera was not working.
I wrote back the original cert nv and efs and registered them officially. Network, camera and voice were Ok after this but still the wifi problem loosing and forgetting pw + unable to set screen lock.
Tried everything mentioned in the forum. build.prop change,
update several firmwares but no change.
Both problems are still there. I have no idea anymore.
Both handsets are on the newest firmware updates through smart switch but still no solution. Any suggestions?
I spent more than 3 days and I am really frustrated.
Thx in advance
