Unlock request - Huawei k3770 modem - Vodafone Egypt

[brave_heart]

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.
