MC7700 firmware update

Hi, I updated using this file
After two reboots my notebok just doesnt see any modems at all, like it is not plugged in. Is it died? Any way to fix?

Hi @okashichandesu

Do you see DM port in the device manager?

Hey! Sorry for not answering for so long. After some days i just dropped that idea to fix my mc7700.
But now, i hope you can help me.

So, no, i have no any DM ports in the device manager, also i cant see any activity in linux-system. It acts just like not plugged at all.

As far as I remember, after running the file mentioned above, everything was fine with my modem. But as soon as I rebooted my computer, it seemed like physically disappear and does not show any signs that it is alive from my view.
