Huawei E5577 comes with Authorization version 4 (V4 Algo) and there is no direct way to unlock it. For unlocking you have to flash the device and I need testers, since I have not personally used it.
In this post I am sharing two firmwares, any volunteers can test it. After testing leave message via comment, unlocking solution will soon come. If any person have solution then also he can share it.
