Recently, I had written the article about unlocking of Saudi Arabia Zain E5172AS-22 WiFi router. Like other Huawei FMC routers, as I had mentioned in the unlocking of Huawei B683 (Orange Uganda), STC E5172s-920 (Saudi Telecom company) can not be unlocked. Other routers which come with USB port like E5331, E5332, E5776s, E5830, E583x, E585U-82, E585, E586, E587, E612/E618 and various other R series routers like R201, R210, etc can also be unlocked easily. But, to unlock STC E5172s-920 Huawei WiFi router, neither Huawei modem code writer nor CardLock Unlock tool software will work.

Huawei E5172s-920 WiFi router can not be unlocked with FMC unlocker software too.

How to Unlock STC (Saudi Telecom Company) Huawei E5172s-920 LTE CPE Router Gateway?

1. Reset the device and connect to Windows PC with its default LAN cable.

2. Browse its default IP address ( from the Internet Explorer.

3. Login to device dashboard with admin username and password.

4. Go to the Settings.

5. Search option for SIMLock / NCK.

6. Enter here correct 8-digit unlock code / NCK.

7. Click Apply.

Now, the device should automatically reboot and show the network of inserted SIM card. If not then, reset the device from its reset button. You should be able to see the network now. Configure the profile according to the new SIM card and make it default. Now you should be able to browse the internet.

Note : Don’t use any wrong / free codes into STC Huawei E5172s-920 Huawei WiFi router gateway, otherwise it will be locked permanently. Either purchase from any server or just pay 2.38 USD for router code through PayPal button of this site and mention model and IMEI in the transaction. The correct NCK / SIMLock will be delivered to your inbox within 8 hrs.

  20. unlock Huawei E5172S 927 STC router

    Important! It is better to use a LAN cable to connect to the router not

    Download the firmware named: E5172S-920_Anti_STC_927_Update from the link below. The firmware unlocks the router by
    downgrading it’s firmware to the
    firmware for E5172s 920.

    Access router manager by entering
    (also written on the bottom of the router) into your web browser.

    Enter the user name and password for the router
    ( default user: admin password: admin)

    From the HOME page go to UPDATE.

    Click on
    browse to navigate to the place
    where you downloaded the E5172S-920_Anti_STC_927_Update file too and click on open to select it.

    Press update and wait for it to finish. When it
    has finished click on login to once again login to the router manager.

    Download the update firmware from
    the following link or any other firmware you want. Different firmware give
    access to different features available on the router that STC block, such as,
    external antenna, voice calls, different frequencies etc. The linked firmware
    unlocks most of the stuff.!sQxFWR4I!nwuYOOYj1Yzicrp6jLzOW3386g1SNVODek_y2vM0Fdc

    Search the
    folder until you locate file named: MPWUDPUPDATE_V200R001C115SP100.BIN

    Once again, login to the router manger and
    update the firmware following the previous steps (4 – 6).

    When it has completed updating, login again.
    That’s it! Your router is now unlocked

    If you want to update the firmware you have to
    first update with the file named: E5172s-927_AntiOM100.BIN then update with your desired firmware.
