I have already written about unlocking of Huawei LTE CPE B593u-91 (B593) MOBILY Saudi Arabia. Earlier, it was available in the market with un-customized firmware, means unlocking was easy, with the only unlock code. But, new Huawei routers still carry model no. B593u-91 but Mobily has changed the UI of the device and no one is able to unlock it because there is no place to enter the unlock code.

However, unlocking can be achieved by a firmware upgrade (download link is provided at the end of the article), which is risky, however, it is tested and working with Huawei B593u-91 of Mobily carrier.

      • Hi, i got same error, but i found the solution, This error comes because the version which i used in my windows 10 machine, not supported, so i tried on windows 7 OS with old winrar version, then it accept the file and update it successfully. Try it. Best of luck

        • It is possible to solve that error on Windows 10.

          Note that the point of this exercise is to “Bring the Device” in “Recovery” mode and not to upgrade the Firmware just yet.

          So just unzip the .bz2 (firmware) file and then you’ll be another file named “B593.trx”.

          Now in the Upgrade Tool, select the “Policy” as “Router” and Open the “B593.trx” file. This time the tool will give no errors. Press “Start” on the upgrade tool and continue as instructed on this web-page.

          This will definitely get the B593u-91 device in the “Recovery” mode.
