Samsung Galaxy S III GT-I9300
i have updated to 4.3.2 and the problem started prior to it was working fine with ICS 4.0
i am able to search the network and it also register it , if i select it manually still on the notification bar it shows selected network is not available
i took the efs backup after flashing it , but it does't get corrupted i believe , but when i try to extract it in the recovery mode it show signature verification failed
i think my efs backup is not corrupted and it is intact but i am not sure...
i have downloaded Galaxsim Unlock after i flash the new rom and try to backup it says
"efs backup failed.stopping here to prevent eventual errors"
i downloaded HexEditor and it show the files in efs folder
i have tried with efs professional software and it backup the efs.img file in the pc , when i opened it it is empty
i don't think my efs backup is corrupt
but not able to fix "Not Registered on network"
i am attaching the images would request to to please check so you can find ,where is the problem actually
i also found that every time i updated different JB 4.3.2 ROM the last two digits of the IMEI of my mobile changes from /01 to /11
355944047XXXXXX/01 when i flash it 1st time
355944047XXXXXX/11 when i flash it 2nd time
