(was running on leaked 4.2.2). after flashing the device i rooted it with CMW to reset flash counter and then flashed again to official 4.1.2.After Flashing the device screen appears No service & IMEI changed to 0049.....
Then i downloaded new firmware from sammobile.com.Now got everything back IMEI is correct have network but am unable to get HSDPA network.phone is working well in GSM Mode but as soon as i chooses HSDPA gets same problem of No Service.
