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 The files needed are nested several layers deep in Zip files, along with some dubiously outdated documentation.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

    i’ve skipped step 1 since i already had the drivers, i’ve done steps 1 & 2 successfully..

    is that it ? i have done a hard reset, i noticed it is updated and the web interface has changed from local mobile vendor to Huawei logo, but the default APN profile is still the same, i have the feeling not everything has been wiped..

    any ideas ?

    • That sounds normal to me. The default APN is still saved from before but can now be changed or deleted.
      You will now also be able to roam if that was previously disabled.

  2. hi every one

    kindly , i would like to ask you about the TXT on the LCD screen
    how can i change it ?

    kindly your supports

  3. hi
    i try the update on fastlink but not working i have error 17

    please help me


    • No, Fastlink modify the devices, so this update is not possible, as far as I know. Sorry.

        • I can’t help you, sorry.
          The white Fastlink modems cannot be updated using this software. If you read through older comments you will see that other people have tried and failed too.

  4. when i try to update is asks for password…plz tell me the password

    • You need to go to the website linked in the article. The password is generated from the serial number.

  5. Hi Will.
    Just quick question. Do you know how to unlock Wifi bandwidth 40m. After update there is only 20m available. I’m using Software version: Web UI version: provided by saunalahti.fi,

    • Hi. I don’t think it’s possible to set 40MHz any more, but setting to Auto should give you the best speed if your wireless device is kept close to the router. Even the 20M setting gives you 65Mbps, which, unless you get REALLY fast 4G, is more than plenty.

  6. I have been trying to configure my new E5776s-32 device with no success. I have discovered that the model I was sent is different internally from the manufacturer (see below):

    Device Information from UI:
    Model: E5776s-601
    IMEI: 860274020470878
    IMSI : 712012007468230
    Hardware version: CL4E5776SM
    Software version:
    Web UI version:
    MAC Address: 50:9F:27:04:89:80
    SSID : iinet-E5776-8980
    WiFi Key : H7YNA689

    Information inscribed on the back of modem:
    Model: E5776s-32
    Hardware version: CL2E5776SM
    IMEI: 866089012120172
    S/N : Q7G7NA9352909295
    MAC Address: 4C:8B:EF:2B:EE:9B
    SSID : 4G-Mobile-WiFi-EE9B
    WiFi Key : 2T2GE87R

    Can the firmware for the E5776s-32 model be downloaded and flashed into this E5776s-601 device to fix this or is this a hardware problem that needs to be exchanged for the correct model because the chip inside is different.
    Thank you

    • Hi. Thanks for your question. According to other people who have commented this firmware can be successfully flashed onto your device, however I’m pretty certain it won’t help you, as the hardware inside is different, as you thought.

      This website has some specs and frequencies for the different versions: http://www.store4g.com/huawei-e5776/
      It sounds like somebody has swapped the back case on your device, so if you can get it replaced I definitely would.
      Let me know how you get on.

  7. Dear all,

    I testing the e5776s-32 in japan docomo network. But, I have problem for join the network in docomo. My e57762 just display Docomo logo and received full signal , but, can access internet. I used difference network operator and result is same. The test sim included ” japan travel sim” and ” So-net”. Could you help me to fix?

    Best Regards,

    • Hi Eric,
      Sorry for the slow reply.
      Please see my previous comment about Docomo LTE bands. The e5776s-32 is unsuitable for use in Japan, unfortunately.
