Vodafone K3770-Z Unlock/Dashboard Problems Solution.

Here I will discuss problems on K3770-Z Modem After/Before unlocking.


=>I unlocked more than 250 Modems with MF192 Unlock file but i never got any problem after unlock.You can see unlock tutorial using MF192 File at here:

K3770-Z Unlock Solution ( MF192 File )


Problems after unlocking discussed below.


1.  Driver Problem

=> It's common problem because all system have not all drivers ;)

You can download drivers for MF186 & MF192 both from here. (4.74 MB)

=> If problem not solved then follow step 2.


2. Dashboard Problem

=> When above drivers not works even manually installation then you can use this ISO file for install dashboard software without your modem.


3. CD-ROM Problem OR NO Virtual CD After Unlock.

=> You need to send AT-COMMAND to Modem...Refer this tutorial :

[Tutorial] How to send AT Command to USB Modems

=> AT-Commands for this modem :

    • AT%USBMODEM=0 => "Only a modem."
    • AT%USBMODEM=1 => "Modem + CD ROM".
4. Unlocking error after 98% Updating Done.
=> Will discuss later :)
