MTN carrier of Ivory Coast is providing Huawei E5573 (E5573s-856). It has firmware version After trying the various firmware, I found only two is working, Huawei E5573s-856 Update (Universal) and Firmware Update Huawei E5573s-856 21.315.15.00.00 General. Both files get successfully installed in the device. After installing these files, the device is working fine. Other firmware’s are either giving error 19 or error 17.

Huawei E5573

Here are E5573s-856 router details:

Found modem : E5573s-856
Model : Huawei E5573 (untested)
IMEI : 866837021119761
Serial NR. : TBCDW15916001734
Firmware :
Dashboard version : WEBUI_17.
SIM Lock status : Locked (Card Lock)
Wrong codes entered : 0 (unlock attempts left : 10)

Huawei E5573s-856 comes with Algorithm v4 and without activating the serial port, unlock code can not be generated. To activate the serial port, it needs a firmware like Huawei E5573s-856 Update (Universal), but it could not succeed.

If any person has the device, then can try out the firmware from this link. I will update the post if I get any other solution. If you have any idea let me know.

Update: The final solution is only shot the board with boot pin and then install the firmware. I did personally in Huawei E5573s-606 (Smart Tanzania) that was carrying firmware version and software / WebUI

Update II: E5573s-856 (Globe Philippines) is also possible to unlock after the boot shot. It comes with firmware version and WebUI In similar ways, shot the motherboard of E5573s-856 (MTN Ivory Coast) and upload the bin file as described in the boot shot method. Once bin file is uploaded, update the device with firmware v21.315.15.00.00.

Note: IMEI will be erased and you will see 00000000. It will be fixed after paying 6 USD. For payment, you can use PayPal button of this website.

Update: MTN Cameroon has launched Huawei E5573s-856 with firmware version, WebUI and hardware v CL3E5573SM02.


  1. I successfully shot the motherboard of my E5573s-856 and update with usbloader.bin (for E5573s).

    But when I try to install a firmware of E5573s, I get “error 12: couldn’t retrieve device info”.

    I can’t update my device with any firmware. I get always error 12.

          • I already know it already, it’s just the term we use is jumper or magic point when we unlocked the new B315s-936 v21.313, also no com port so we use what you call boot shot to detect. But I have a doubt to unlock my e5573 since I read the other post about the imei/sn issue. I only need to get the hash code to unlock but if that’s the case, I think I’ll just wai. 😀

            Thanks for this info.

              • I’ve gone ahead since I already broke the seal but I have trouble in drivers, mobile partners’ driver doesn’t work and the hilink v5 too. I tried FC_Serial_Driver_Setup.exe that I got from unlocking b315s,it’s detected as FC-PC UI interface,tried to send AT command but no response as well as updating the firmware,same error from above comments error 12. Battery led fading on/off after loading the usb bin from balong. I’m going to clear all the drivers first and go back from start.

  2. Same with macclann comment. Modem is dead after loading the bin file in balong. Although I still can boot shot and load usbloader. I’m just wondering about the com port, is it really FC – PC UI interface?

  3. My device is same e5573s-856 globe philipine model but after boot shot and loader.bin write unable to write any firmware to the device error 12. I have downloaded the webui as stated above but unable to load it to device error 12. Now my device can not boot just blinks and stays on for some seconds then reblinks.

  4. Hello, is it possible now to unlock the smart tanzania mifi router e5573-606 with firmware without the shot the board method?

  5. hello sir i have tried updating the device but i got error 12 unable to get device information. it really hard to load a firmware into this device. Please if there is any other way to load firmware into the device i will be please if you share.

    • You are confused with firmware and unlock code. There are two different things in Huawei. For E5573 without changing the firmware it is not possible to generate the unlock code, that’s why this much big instructions are written over the post.
