K3765 or E180?

[marcogaio]

I've just acquired a 'Vodafone' branded modem because i was curious to experiment a bit with asterisk's chan_datacard.

Anyway, i've found this modem on a local exibition of retrocomputing and things like that; was sold as ''unlocked''.
The modem have printed on:

Model: K3765

but once connected react to an ATI0 as:

Manufacturer: huawei
Model: E180
Revision: 11.104.16.21.00
IMEI:
+GCAP: +CGSM,+DS,+ES

Note the missing IMEI: chan_datacard need IMEI, so i cannot use it.

The modem seems really unlocked and voice capable, react to an at^cvoice? with:
^CVOICE:0,8000,16,20

I've also opened the shell, and a stick inside confirm me that is really a K3765, probably flashed with the wrong firmware; googling around seems that the missing IMEI could be ''normal'' behaviour of a wrong-flashed modem.

There's something i can do to restore the right flash? Again, googling around seems that i can simply open in hex editor the flash .exe program and remove the model check (or make it inoffensive); someone have some hints?

The strange thing is that, even with wrong firmware and empty IMEI, data connection works as expected... boh...

Thanks.

K3765 or E180? (wrong firmware flashed)

No, seems that simply altering the strings resources inside firmware exe file does not suffices to fake version, and so restore the original firmware.

Someone have more hints? Thanks.
