Unlock request - Huawei k3770 modem - Vodafone Egypt

[nnm]

You can't imagine how do I appreciate your reply, I 'm a good researcher and successfully unlocked many modems for my friends, however this one Huawei K3770 is so difficult.
when i started to unlock it:

First: I installed Mobile Partner which asked for the unlock code.

Second: Before your appreciated reply I tried to enter many unlock codes (apparently I passed the 10 times limit).

Third: Now it is keeping telling me invalid SIM (not enter the unlock code message)

Finally: I am trying to reflash the modem or reset its counter (any help will be appreciated)

Thanks in advance.

reset counter search on google or try to flash another firmware then try unlock code
