Hi, I am having the same problem with this version of samsung. I am using z3x Box to try to write back the original IMEI but it keeps writing the same fake IMEI(350695200123951).

I have tried it with both the T-Mobile Firmware and the MetroPCS Firmware. Could you please help me.


Thanks.

This problem is common on this model, I will explain how to solve this problem.

1- I use this flash T399NUVUANK3_T399NTMBANK3_TMB this on: samfirmware

2- write a backup of a EFS of a T399n working OK.

3- Repair IMEI is written as the backup of EFS

4- Unlock.

Phone working OK

Hello,

Have anyone managed to get this problem solved and working?

[Amarjeetverma]

Should I buy Samsung t399n ?

[Afzaal Aslam]

if you have t399n t-mobile with no service,although imei and baseband is not corruppted,then in repair tab just fill imei field and use patch certificate tab, all will be ok.
I have done T399n with no service today.

I had 6 phones with the same problem and finally got it working. Thanks!!!

[teammonoxide]

is not necessary to flash. Just repair your imei, do sim unlock and repair network. Works 1000%

Anyways, this guide was so useful

[skets]

none of these tutorials is not working, i have octoplus and whenever i click repair on imei or unlock the process starts but never finish , the software just stop after a while and nothing happens. if i select repair network everything goes through and the phone restarts but no other option works

[TechnicalFerdy]

Am having issues, repaired the IMEI successfully to match the one on the sticker after the unlock process made my Generic IMEI the same as everyone elses. Flashed all t-mobile files, modem, code, etc etc, and repaired IMEI, patched certs, and reflashed metroPCS firmware and modem files. Now phone says Unknown for everything, but the IMEI is correct. patching certs doesn't fix the issue. I can't use my phone, help please!

A little later the answer, but just today I read this post.
You do not work you do not mean it is not correct the tutorial, it is more than proved by me in over 80 phones and go to 100%.
In some cases it is not necessary to flash, it's just try and fix the problem.
Look at Google EFS backup t399N.
