Unlocking of Huawei E5172s-920 STC Router of Saudi Arabia is very easy, as it comes with un-customized firmware and after changing the default SIM with another network SIM, the device asks you to enter the unlock code. For single unlock code, the charge is only 2.38 USD, while for bulk you can refer this post.

But, Huawei E5172s-927 STC router of Saudi Arabia comes with customized firmware and does not ask you for unlock code. This article is based on Hasan Abdullah comments at http://modemsolution.com/unlock-huawei-e5172-stc-saudi-arabia-wifi-router-gateway/#comment-1918684201

According to the comments made, E5172s-927 can be unlocked via firmware upgrade process only.

How to Unlock Huawei E5172s-927 STC Router of Saudi Arabia

1. Download the firmware E5172S-920_Anti_STC_927_Update and unzip in a folder using Winrar.

2. Make sure your router is connected to a constant power supply, during firmware upgrade process, any power failure will make dead your E5172S-920 STC router.

3. Access router management page by entering (or refer bottom of the router) into your web browser (better use Internet Explorer).

4. Login to device using username and password of the router (default user : admin / password : admin)

5. From the HOME page go to UPDATE.

6. Click browse to navigate to the place where you have extracted the E5172S-920_Anti_STC_927_Update.BIN file and click on open to select it.

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

8. Download the update firmware from the following link or any other firmware you want. Different firmware gives access to different features available on the router that STC block, such as the external antenna, voice calls, different frequencies etc.

9. Download Huawei E5172s-927 STC Router unlocked firmware (MPWUDPUPDATE_V200R001C115SP100.BIN)

10. Once again, login into to the router manager and update the firmware following the previous steps (4 – 7).

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

12. 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.

Note : We have personally not checked the procedure. Do it at your own risk.

  2. i download n try to update my huawei LTE CPE E5172-927 router. but at the middle of updating coming an error. verification failed. pls help

    S/N 354641015126017

  3. i have been trying and keep getting file verification failed, is there a way to disable the file verification process? i have tried E5172s-927_AntiOM100, MPWUDPUPDATE_V200R001C115SP100, MPWUDPUPDATE_V200R001C209SP100 all Firmwares but i keep getting “file verification failed”, i have downloaded the E5172S-920_Anti_STC_927_Update twice but unzipping says error “file corrupt”. been on this for 4 days now. Any help would be appreciated, this device is driving me nuts, but i am not ready to give up just yet.

    • hello, if you still want it done, you can contact me, i have the firmware that will work with spectranet routers, but you should know it comes with a price tag too. 08035243218

  4. i just downloaded E5172S-920_Anti_STC_927_Update successfully and still the same error “file verification failed. Please what can i do?

  5. Thanks Kamlesh for the guide. Still the same error, i have checked the video but i still have the same problem, i have tried it on 3 laptops in the office now, including mine and all the same results, i have tried 3 different firmwares. i have followed all the steps to the very last letter. Am i missing something? when i plug the LAN cable i can access the admin panel so i am sure there is a connection, and also the modem is not online, but i connected the pc to the internet via Wi-Fi network.

  6. Thank you very much….I followed the process and I was able to unlock my STC modem without any issues…For those getting any error i wud suggest:
    1. Use IE instead of Chrome etc.
    2. Use Jzip if the file shows error while extracting via winrar.
    Thanks again

    After updating login again on your router and update another file which is known as firmware….

    from https://mega.co.nz/#!sQxFWR4I!nwuYOOYj1Yzicrp6jLzOW3386g1SNVODek_y2vM0Fdc

    This file will be in Arabic but dont worry open the folder and find the file in software folder.

    file name is MPWUDPUPDATE_V200R001C115SP100.BIN

    Then restart your router and login again with the new sim of other co. Most of the time new sim will be locked, so put your sim’s pin.
