Weird unlock status of Vodafone K3770

[ad_rai]

I bought a Vodafome K3770 from Czech Republic during my trip, and tried to unlock to use it home. While DC-Unlocker reports modem as unlocked like this:

Found modem : K3770
Model : Vodafone K3770
IMEI : 860030014******
Serial NR. : S8X5TB11B*******
Firmware : 21.023.04.00.11
Compile date / time : Apr 12 2011 16:56:33
Hardware ver. : CH1E173SM
Dashboard version : graham_inggs_custom_iso
Voice feature : not supported in current firmware
SIM Lock status : unlocked
Wrong codes entered : 10 (unlock attempts left : 0)

================================================== =================

but AT^CARDLOCK command's output is somewhat weird.

AT^CARDLOCK?
^CARDLOCK: 2,0,0
OK

Now, the modem can at least pick up non-Vodafone SIM cards and displays IMSI and phone number on it, and operator scan reveals all non-VF network, but refuses to join any. I tried to flash the firmware of E173, but HiSilicon firmware writer refused to write. Any suggestions to revive my K3770?

If you have damaged modem then sorry do not have solution to revive it. Unlock for it is done by inserting invalid operator sim, in your case non-vodafone one, then detect and then unlock.
