Chosen Solution
Running OS 4.4.2. IMEI changed to 00499. Sim Card Detected but Not resistered on net problem. Tried several methods without BOX. Already tried: 1) Modem Install by ODIN, 2)Patched modem Zip install via Bootloader by recovery. 3) EFS backup and restore, 4)tried NV data restore bt EFS professional software not working. Really really too much stressed on this issue. Need a proper solution. From Bangladesh
EFS got corrupted / wiped. You’ll have to repair IMEI with Z3X box. There are people out there that can provide the service remotely.
