ZTE MF667 unlock is bricking usb modem

[ecdteck]

Hello I am having problems with unlocking ZTE MF667.
Before I unlock them the working fine auto play works, I can see the hard drive of the usb mode so I can install driver and software. The software talks to the usb mode fine so I can get to the dashboard.

After I unlock them using dc unlocked the PC load the driver for it but that is it.
Auto play does not work. I cannot see the usb mode hard drive. Also the usb mode software does not talk to usb mode. There is no way of getting to the dashboard at all.
Dc unlocker will still see the modem and it does say it unlocked.

I have tried two windows 7 pc and one windows 10 PC it is the same on all of them.

You need to disable diagnostics com port, detect on dc-unlocker, in unlocking tab press disable diagnostics port, disconnect modem from pc, connect back, you should be able to see it's drive in computer then.
