Help ZTE ZMax2 Z958 ATT Bricked to Root & Repasir Serial, Help!

[GabrielCh]

Hi, try to Rotate a ZTE ZMax2 Z958 ATT to repair IMEI: Unknown, compilation version: Z958V1.0.0B16B, Android 5.1, 10/10/21015 and Full Bricked with GRT Dongle, just restart on ZTE logo and then turn off, on screen black, but the ZTE Handset Diagnostic Interface Driver is detected. I am trying to Flashear the ROMs of your download page, with the Update method with the MicroSD, but the versions of your page cannot load the firmwares, probably because of the compilation versions (bootloader is close ..)

I need the Firmware ROM Z958V1.0.0B16B. Any suggestions

It now adds failures too in the Access GRT Dongle server!
