I9250 IMEI Repair (Need Help)

[Helvio]

Hello! I have a Samsung Galaxy Nexus - GT-I9250 with a null IMEI: 004999010640000

I'm trying to use my z3x-box to repair it to the IMEI printed on it's label. I have tried both USB modem and COM port methods, but none work.

This is the output for COM port:

Selected model: I9250

This is the output when I reboot phone indo fastboot while connected and searching for phone in COM port, using 3300k cable:

And this is the output for USB modem:

Please have in mind that I have installed all the drivers, adb, bootloader, download... Also, while box is searching for phone, I have tried to reboot it, put in download and bootloader modes, as well as rebooting into android itself. None of which gave me any results.

Anybody there could give me the key to make it work?

Thank you!

simple UART cable. just need resistor 680kOm . i think that will solve your problem
