After "successfully" unlock Huawei E3131 - become not unlocked!

[Zsolt]

Hello! I tried to unlock modem Huawei E3131 with DCUnlocker, who wrote that the modem is successfully unlocked. Credits has removed from the account (4 credits), but as it turned out the modem was not unlocked! That was in the late July. Then I went on holiday to the sea. What do I do now? Can you help to unlock modem? After all, I paid for unlocking the modem! I hope for your understanding.

Unfortunately but this firmware that your device runs is not supported by dc-unlocker at the moment, maybe someday in future, no exact date. Currently there is no solution to this problem.

Credits that you've spent unlocking it were added back. If you'll want a refund for them, you'll need to contact reseller that you've purchased from.

Thanks for the quick response! Good support!

To unlock this modem you just need to change firmware to E3131Update_21.158.00.00.1020.B757 (and maybe dashboard)
