ZTE K3675Z - "modem not found"

[retrok]

Hey,
I purchased credits to unlock my ZTE Vodafone K3675Z and followed all suggested steps, but I still get the message "modem not found".

Here is what I tried:
Inserted unsupported sim card into the device
Installed official Vodafon Mobile Broadband Software which recognizes the device (but not the sim card)
Closed the software and opened DC Unlocker with administrator privileges.
Selected "ZTE modems" and "Auto detect (recommended)" and clicked on the magnifying glass

This is the result:
DC - Unlocker 2 Client 1.00.1431

Detecting modem :

selection :
manufacturer - ZTE modems
model - Auto detect (recommended)

Enabling ZTE modem driver... OK
Waiting for ZTE modem...

modem not found !



What else can I do? Are there other drivers than the Vodafon Mobile Broadband Software I can try?
Thanks for any help

You need to open device manager on pc and monitor what happens there with your modem when you try to detect it, it should be visible under modems/ports sections.
