you dont need such complicated steps.
Dont matter if the phone is 4.0.4 or 4.1.1

Just root it then write IMEi again.
The phone will be OK with signal and everything...

rufnafuk · 11-03-2012, 16:41

Would you have to write the imei every time the phone is updated?

if the update is by OTA, no. If the update is by Kies or Odin, yes.

Eric_cn · 11-04-2012, 03:05

but after update to 4.1.1 by odin,signal was gone,and IMEI/SN all normal.I tried to fix it again successfully,signal same....so I restore efs backup.then fix it and work.

Make sure you write the original S/N on the phone when repairing IMEI.
Also the IMEI must be a VALID IMEI.
If you write IMEI 123456789012.. the GSM provider network wont accept the phone to register.

Make sure you enable debug mode on the phone, and the phone is rooted.

mobilecareuk · 11-06-2012, 13:44

yes the phone is rooted and usb debugging enabled, and computer picks up drivers but still no response from nspro?
