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 The files needed are nested several layers deep in Zip files, along with some dubiously outdated documentation.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. Thank you!

    Easily updated from by a win8.1 tablet. However I first got that “Error 10 Find Port Failed”, but worked out after unplugged and re-plugged the usb cable. (Reason the tablet had freshly installed Huawei drivers?)

  2. Tried updating webUI but after update, cellular works but “wifi-off” and can’t log in with “admin” “admin”, error incorrect username or password. (other usernames and passwords also do not work) anyone has a solution??

      1. Power on the Huawei Router, place a paper clip or Pin into the hole on the back of the Router labeled Reset.
        Hold paper clip or pin down for 10 to 15 seconds and release.
        The Router will reboot on its own. Once the WLAN light stops blinking, the Router is reset.
        Please Note, Resetting the Huawei router does not reset the firmware to an earlier version. It will only change all settings back to factory defaults.

  3. I get error 19 (download failed) after the update process is about 90% done. Now my router is stuck in update-mode. Any tips?

    1. Not heard of that problem before. A factory reset MIGHT help, as long as the update hadn’t started actually installing.

      1. The original files on the Huawei web site is not available. You would not remember how to do an sd-card update instead? I’m pretty sure the file contains some binary file that needs to be called something and placed on the SD-card. But I don’t know which file and what to call it 🙂

        1. Hi Paal. Sorry, I don’t, I did try the SD card update but could never work it out either. I’ve sold my e5776 now, so can’t try any more!

          1. Soeren, your bin file for sd card update didn’t work, i see a cross on screen. any help?

  4. Cant log in to admin after upgrade firmwire ( just blank page showing

        1. viki – did you manage to get it to work??

          I have the exact same problem now

          And I am afraid of doing a factory reset – because this will clear everything and then if I still cant get into the web interface??? What to do…
