MF190 & diagnostics port: stuck in boot loop

[TOMillr]

So I've just used DC Unlocker to unlock my ZTE MF190 modem. However, I've since accidentally hitting the "enable diagnostics port" button, the device is stuck in some kind of boot loop.

When I plug the device into the usb port, it loads up the so called "internet manager" software that comes preinstalled with the modem. But it now also displays a message saying that the "update was successful" and that the software will restart. I can also see some kind of update script that pops up in the background for a second.

Any idea what's going on here?

I think this can not be caused by enabling port. Detect it by dc-unlocker and click disable diagnostic port if you think it was caused by enabling port.
