Huawei E5770


I got a E5770 locked to O2 that is on Firmware : 21.200.19.01.405.
It doesn´t allow me to downgrade to 21.180.99.11.00 and the unlock code I got doesn´t work on 21.200.19.01.405....
Is the unlock code linked to the Firmware or do I have a wrong code?
IMEI 867472020349240
Would love to have it unlock and get rid of the O2 surface.
Thanks!

As i know, the fimeware is not related to the lock status. It must be other problem.

Try the Unlock Code = 45614562
