Updating Huawei E5776s-32 Firmware


This article describes the steps involved in updating the firmware of the Huawei e5776s-32 4G Router.

The necessary update files for Windows users have been uploaded to my web server, to make accessing them easier. For the paranoid (i.e. sensible!!) user the originals are available at the time of writing at http://consumer.huawei.com/en/support/downloads/detail/index.htm?id=22287 . The files needed are nested several layers deep in Zip files, along with some dubiously outdated documentation. The original Huawei download also includes Mac and SD Card update options, so is much more flexible.

It goes without saying that any attempt to update firmware is at your own risk, and if it went wrong you could render your device useless. You have been warned!

Before you start you need to have available the flash memory password, which can be calculated using this online tool. Make a note of the password, which should be an 8 digit number. Ignore the unlock code – that won’t do anything (including unlocking the SIM)!

Download firmware version or get it from the Huawei link above. Connect your router via a MicroUSB cable, and wait a few minutes for the drivers to install. If this is the first time you have upgraded the firmware it might be necessary to install an updated set of drivers onto the router, shown in step one. If you have already done an upgrade (like I had) this won’t be required. The following instructions should be carried out in the order stated. If you get an “Error 10 Find Port Failed” message make sure that you have the drivers and connection software correctly installed, then try again.

  1. Run the file Update_UTPS1.12.00.414_MAC1.12.00.414.exe This will update the drivers that are used to communicate with the router. First the new files are copied to the router, then the router should be recognised as a new device and the new drivers installed on your computer. Let everything finish. A reboot wouldn’t do any harm at this stage. (This file isn’t included in the Huawei download, I got it from the German firmware upgrade package – see original post linked below)
  2. Run the firmware upgrade file E5776_Update_22. This is the stage that requires the password generated earlier. It doesn’t take very long, and the router will reboot itself a couple of times during the process. This is normal.
  3. Finally, once everything has settled down run the last file, Update_WEBUI_15. I don’t think this is essential, but having got this far you may as well. This updates the web interface, and includes a new connect/disconnect button and support for the same feature via the Huawei mobile App

Enjoy your new unbranded router. Let me know in the comments if this fixes issues such as losing signal at random. Some things I’ve noticed:

  • The LED display now has extra symbols for when data is being transmitted/received.
  • There is a prominent connect/disconnect button on the router homepage (see below).
  • My data is provided by virtual network Globalgig, I now get their name showing instead of 3, whose physical network they use.
  • The data counter on the LED doesn’t reset after power off.
  • There is a new monthly data counter, you can set billing date and allowance to avoid going over your package limits 🙂
  • Different language options, including Arabic, Chinese and Russian (see screengrabs below for full set and monthly limit setup).

One more feature that has been added is support for remote connect and disconnect using the Huawei Mobile app, which may be handy for some people:

Some people in the comments have mentioned signal issues. This isn’t something I’ve come across personally, but an external antennamay help in some situations. These aren’t signal boosters as such, but they can be placed in positions that might help get a stronger signal, eg through a window.

  1. Thanks for the link to the unlock calculator.
    After flashing to the branded firmware for the e5786 due to t-mobile sim card issues I was not able to get back to the open firmware because of the missing code, but this link finally made it. Tried a lot and searched a lot until I finally found it via your site.

  2. Hi, i just updated my huawei e5772-420 mifi but now screen is blank.
    what do i do?

    • I don’t know, this thread is all about the e5776s
      Assuming you didn’t get any errors during the update your device should be fine, so do factory reset, long press and hold on reset button.

  3. with default user name/password when tried to login without upgrading the webui.


  4. Hello,

    I have update my E5776 from Orange France. All is OK and work fine 🙂
    Now my modem is Huawei not Orange !
    Thank you very much for nice tuto !


  5. Can anyone tell me how to get into advanced setting on firmware or which firmware has advanced settings.so I can change DNS settings.

    • I would also like to change the DNS settings if anyone has figured a way to do it.

  6. hi
    my device is sim locked
    will this make it go away?
    can i use any sim card with any operator after doing this update?

  7. The link to flash memory password does not work. Where can I find the tool?

  8. Hi, any new firmware? And where can I track the latest firmware?

    • No, unfortunately not. Huawei are very poor at releasing firmware, and I haven’t found anything more recent.

      • Hi Will, wondering if you can help. I have 2 E5776 devices. One works just fine. The other one does not broadcast WIFI and on the management UI it says that WLAN is off. I tries changing the WLAN bandwith but it does not help at all. The issue is described at: http://forum.xda-developers.com/showthread.php?t=2732031

        It had the same issue with the older firmware. Any clue?

        • Hi Dejan
          If you look through the older comments there is one from 29/07/2015 about missing WiFi. You could try the steps I suggested then
          Unfortunately the person who asked never replied if it helped or not.
          Thanks for the message.

          • Many thanks, it did not work… I can’t find any way to turn WLAN on or off at the mobile UI. But there should be that switch somewhere. The device works just fine when connected to PC via USB cable as it connect to the internet over 4G. So, we should be able to turn on and off WIFI… So, it is just that WLAN does not transmit!

          • You can access the web interface on your PC even if connected via USB. Just go to
            You might be able to change more advanced settings than the mobile UI allows.

          • yup, tied everything of that – no way to turn wlan on or off :(. It says that it is off

  9. Well… unfortunately I am a bit of an unlucky one as I can’t find the original firmware (and web UI) anywhere for my device that is a E5776s-420. I can’t find anything in the Huawei website, I can’t find anything anywhere… so I am not exactly a happy kitty with this one.
    I’ve tried to flash a E5776s-32 firmware into another one that I had (-420 model) and of course… I bricked it instantly.
    So … do you have any idea on how can I resolve this? Any help is appreciated!!

  10. Hi!
    I’ve also been trying to update the e5776 but with no success. Router’s backplate says I have e5776s-32 but in the web UI it says e5776. Still the same thing? This is bought from Finland, Sonera operator but not operator locked.

    But the problem is that after updating the drivers, trying to run the firmware updates gives error 17: selected wireless is not e5776. Or sometimes error 12: couldn’t retrieve device info.

    Trying to update for several times but always the same.

    But for some reason if you’re using e5776 from Elisa or Saunalahti, they inform that you can update the router to (released 12.6.2015) via router’s update function…

    • I had no issues to upgrade Sonera’s Prepaid e5776s-32 from Software and WebUI to this software

      • Thanks Will, upgraded from Sonera to Elisa which was bad idea. Less functionality and some issues (no sms). Then found your instructions here and upgraded to All fine now, great thanks! It seems mandatory to always upgrade the webui as well because I got both times issues with default user name/password when tried to login without upgrading the webui.
