samsung J730GM imei partially lost after upgrade

[Android Central Question]

Hi All,
I tried to update from V7 to V8 by kies, after update everything included imei was
correct checking by *#06#, but "mobile network not available" is shown.
It is said that imei was stored in two different places, the hidden one is sent to gsm
operator and it was erased.
I sent phone to a service (not Samsung service), they were able to set imei. I inserted sim card, phone connected to my operator, everything was good until I reboot the phone, then it started to show the same problem.
I flashed new software by odin, boot U6. Then flashed root boot
I checked it is rooted.
Then I used Z3X v29.5 to set imei again. It is doing job to some extend then an error
occurs. Can any one help to do it successfully ?
The operation log is below.

Thanks, I wasn't able to find how to sign up.
Some more info about my situation, after some time root is disabling somehow. It may be the main problem.
