code for e303s-2

[Hisoka]

thank you very much for the code, the code is correct but my e303s-2 is costomized firmware from vodafone egypt I tried to enter the code using huawei code writer it says ok for entering the code but the modem still locked, I tried card lock unlock but the same problem, I tried using terminal but after using AT^CARDLOCK="56149330" and then AT^CARDLOCK? it returns ^CARDLOCK: 1,10,0 which means card still locked.
I tried to update firmware using these versions: 21.157.31.00.850.B757
21.157.13.00.910
22.157.18.03.910.B734
but all of them says error 19.
dc unlocker says that they don't support e303s-2 from vodafone egypt.

do you have any solution to unlock it or flash it .
thanks
