  1. Hi, i’ve updated my E5251s-2 from 21.143.09.03.192_TIM_Italy to E5251s-2Update_21.146.29.00.00_Universal but dashboard doesn’t work: if i try to go to 192.168.1.1 it redirects always to BLANK page at 192.168.1.1/html/index.html šŸ™

    It’s possible to revert to previous firmware or update dashboard?

    Help me, pls. šŸ™

  2. Tank you for your answer.
    I tried to upload 21.143.09.03.192_TIM_Italy on a different pc, but i have always the same error: Error 16: unable to switch in download mode. šŸ™

    • Then everything is find, try once resting the device, if not work then remove battery and reinsert it, then try to update the firmware. You can use any universal firmware, it will not lock the device.

  3. Hi, problem solved! šŸ™‚
    I’ve tried all USB ports in my pc and with one i was able to upload firmware v. 21.143.13.00.00 and WebUI v. 13.100.02.03.03.

    Now it works at 100% šŸ˜€

    Thank you very much for supporting me.

  4. Hi, we have one Huawei e5251s-2 Wind (Italy) brand, we have successfully unlocked the modem (thanks to you) but we have a problem with connection, login page from some devices stuck in a blank page, from the PC we can navigate, so we tried to upgrade firmware but was accidentally updated with E5372sCUST-B00C1087 file, so now we have a new wireless network called huawei-e5372-**** , **** is like previously wirelss name, called wind-e5251-****, the problem is in a WPA code, the original doesn’t works, via USB we can’t join in to the card by browser.
    How we can downgrade or reinstall Wind or e5251 stock firmware? If we try we receive error 16
    Many thanks.
    Regards
