Mention of EFS/No register network

For the last two months i was trying to restore IMEI number in S3 19300.. I didnt have backup.
i tried more even 10 stocks+modem vers / ARIZA patch and more more..
finally i took it to Lab for reburn the IMEI by box.

Until here all right ?

I took a another different S3 smartphone and wanted to replace Rom,so i backuped by using some applications the EFS( i have 5 backups of efs right).

1.i installed the new Rom.
2.IMEI changed to 0009.
3.so i just backup the efs folder (used one of the 5 backup) and flashed last modem like in the old stock rom+set apn manual
4.IMEI has back to the original but still cant take out Call or Message i got message NO REGISTER NETWORK
5.tried other backup and still same problem.

Now I'm the conclusion which it opened the discussion.
one of the backup was by app called Partitions Backup & Restore https://play.google.com/store/apps/d...nam.partitions
the backup made 2 files one EFS and on Radio .img.
after 4 hours of break the brain i flashed the Radio.img and suddenly i was able to get out Calls and messages.:good:

why most the guides of backup IMEI dont mention the backing of the radio folder?

Thank you.
