[Sony Xperia M] vibhorvadehra:
Hi,

I recently updated my Xperia M to CM 11 19-01-2015 nightly release... But I was not able to connect to mobile or wifi network.

Found IMEI unknown.

Was suggested by various forums to reload the stock rom and issue will be fixed but when I tried to reboot the stock rom using Flashtool 'Flashboot' option, I am getting errors... :confused:

Now the phone is stuck with the SONY boot display.

Require a quick support.

Thanks in advance!

P.S.: I also went to Sony Service Center to get it flashed, they checked the phone on their 'Emma' tool and the device name was Unknown over there whereas IMEI number was listed. Service center was not able to help.
