Firmware Reset for ZTE K3772-Z 5: Troubleshooting Common Issues



Available for 4GR, TINY, DOMA, PRO (initial factory release)Hard on the heels (same day) of 6.2.1, this release Fixed a Live Firmware Upgrade error, preventing 6.2.1 detecting that there is a new firmware available. It was the firmware installed on the first production run of the PRO (release 6 May 2013), but there was never a 6.2.2 download available for that model.

Available TINY (upgrade/rescue utility only)No BIN file was released with this firmware as the resolution included required any TINY to be flashed with a new bootloader using the Rescue part of the utility. The issue fixed is a power-cycling condition affecting some, but not all of these modems: ZTE 110, ZTE 190 and Option Icon 505. See separate blog article for further details.

Usb_modeswitch is a popular Linux tool created for this exact purpose, and unpacking the MR3020 firmware image with firmware_mod_kit reveals that it uses this very tool to set up modems that are connected. The bin file above simply seems to be some obfuscated instructions for usb_modeswtich.


I have the TL-MR3420. I had no success with the bin file at first but then I downloaded and installed the latest firmware upgrade ( -link.com/en/support/download/?model=TL%2DMR3420) and then tried again with the bin file. It took about 8 minutes to identify my network (Vodafone GH) but then it worked. It took a few reboots and resets on the router but it finally worked.


To receive the correct unlock code of a Vodafone K3772-Z, we need correct 15-digit IMEI, which can be found on Settings of the device, or on the sticker.There is no need to change the firmware or software of the modem, means you will not loose the warranty. Unlocking a device by code is the easiest and fastest method. Once, the modem is unlocked, you can use it with any supported band SIM cards around the world. 2ff7e9595c
