Do you see modem in device manager? Under modems and ports?

I solve my case by using the older version of dc unlocker

DC - Unlocker 2 Client 1.00.1057

Funny, using older version, unlocking is like a piece of cake while using the newest version a meet hustles

BTW, can anyone here tell me how to rewrite the firmware to older version as nowdays some new MF90 are using newer firmware while to unlock the newer version firmware seemed to be impossible for the time being
