Can't fix no network N7100 - GSM-Forum

UnReality · 03-10-2014, 16:03

Hi! I got this phone from client who told that after he update his phone to version 4.3 he got null imei. I've tried all possible solutions with 4.3 and 4.1.2 versions with no success. Now I downgraded phone to 4.1.2 version, imei is fixed, but serial is still 00000000000 and I can't fix it.

S/N repair done, but still same, all zeros - [Click to open]

If I power on phone without sim card, then it looks that it have network, but when I trying to make an emergency call, then it lose signal ang get it back after about 20 seconds.

Without SIM - [Click to open]

If I power on phone with sim card inside, then it is no network.

With SIM - [Click to open]

So, is there any way to fix this problem with z3x box atm?

U can fix imei on any version, 4.3, 4.1.2 or 4.1.1. I downgraded to N7100XXDME6 (4.1.2) trying to fix s/n. I fixed s/n with 16.7 as I thought, but only 10 digits was restored, not 11 as it should. So my phone still have no network.

Unpack firmware? U will get build_name.tar.md5 file. Remove .md5 at the end of file, U will get build_name.tar file. After that U have 2 methods how to edit that fw file.
1. Use Total Commander. Start TC, navigate to your file, double click it to open. Delete param.bin sboot.bin tz.img files. It can be only 2 files in fw, without param.bin, then delete only 2 this files. Close file by clicking [..]. Now this file can be flashed via Odin, selected as PDA.
or
2. Unpack build_name.tar using latest Winrar or 7-Zip in any folder, delete files I've pointed above. Pack files back to tar archive using 7-Zip. Flash via Odin, selecting as PDA.

After editing firmware U should get something like this:

FW with no BL - [Click to open]

P.S. I'm using method No.1, b'cos it's simple and TC is my favorite file manager and I'm using it since it was released in public (about 20 years ago).

I'm used only USB cable to repair IMEI. Try to use different z3x software version, 16.7, 16.2 for example.
