Huawei B593u-12 Problem (No system option)

[djtox]

Hi, I'm having a problem in my Huawei B593u-12.
I tried to change the firmware using LAN to upgrade,
but it failed. then I use the recover option.
but when I log in using 192.168.1.1, there's no 'System option'
and now i can't upgrade the device.
can i upgrade it using any software?
or there's an alternative way to upgrade B593u-12?

thanks in advance.

Apologies, but DC-Unlocker does not solve problems related to firmware upgrade failure.
