What is firmware and why do you need to update it?
Firmware definition and examples
Firmware is software that is embedded in a hardware device, such as a router, a modem, a smartphone, or a computer. Firmware provides low-level control for the device's specific functions and features. For example, firmware can determine how your router connects to the internet, how it handles data traffic, how it encrypts and secures your information, and how it interacts with other devices on your network.
Firmware is different from regular software that you install on your device, such as applications or games. Firmware is usually stored in a non-volatile memory chip inside the device, which means it does not get erased when you turn off or reset the device. Firmware is also specific to each device model and manufacturer, so you cannot use firmware from one device on another device.
Benefits of updating firmware
Updating firmware can have many benefits for your device, such as:
Fixing bugs or errors that affect the performance or stability of your device.
Improving security by patching vulnerabilities or adding new encryption methods.
Adding new features or functions that enhance your device's capabilities or compatibility.
Unlocking your device from a specific network or SIM card, allowing you to use it with any network or SIM card.
However, updating firmware also involves some risks, such as:
Bricking your device if the update fails or gets interrupted.
Voiding your warranty if the update is not authorized by the manufacturer or network provider.
Losing some features or functions that were available in the previous firmware version.
Incompatibility with some devices or applications that rely on the previous firmware version.
Therefore, before updating firmware, you should always:
Back up your data and settings in case something goes wrong.
Check the compatibility and reliability of the firmware update from official sources.
Follow the instructions carefully and do not turn off or disconnect your device during the update process.

How to update your router with the unlocking firmware
Step 3: Remove the SIM card and turn on the router
Before you can update your router with the unlocking firmware, you need to remove the SIM card from the router and turn it on. This is to prevent any interference or damage to the SIM card during the update process. You can insert any SIM card later after you have unlocked your router.
Step 4: Connect the router to a PC with an Ethernet cable
The next step is to connect your router to a PC with an Ethernet cable. This is to ensure a stable and fast connection between your router and your PC during the update process. You can use any PC that has an Ethernet port and a web browser.
Step 5: Access the router's control panel with a web browser
Once you have connected your router to your PC, you need to access the router's control panel with a web browser. The control panel is where you can change the settings and features of your router, including updating its firmware.
To access the control panel, open your web browser and enter "192.168.1.1" in the address bar. This is the default IP address of your router. You should see a login page with the STC logo, which means that your router is still locked to the STC network.
The default username and password for your router are both "admin". Enter them in the login page and click "Login". You should now see the control panel of your router.
Step 6: Update the router with the first firmware file
The first step of updating your router with the unlocking firmware is to use the first firmware file that you downloaded earlier. To do this, follow these steps:
Go to "Home", then "Update".
Click on "Browse" and select the first firmware file from your folder. The file name should be "E5172s-927_Anti_STC_927_Update.BIN".
Click on "Update" and wait for the update process to start.
Do not turn off or disconnect your router or PC during the update process. This may cause damage or failure to your router.
Wait for the update process to finish. This may take several minutes.
Step 7: Update the router with the second firmware file
The second step of updating your router with the unlocking firmware is to use the second firmware file that you downloaded earlier. To do this, follow these steps:
Go to "Home", then "Update".
Click on "Browse" and select the second firmware file from your folder. The file name should be "MPWUDPUPDATE_V200R001C115SP100.BIN".
Click on "Update" and wait for the update process to start.
Do not turn off or disconnect your router or PC during the update process. This may cause damage or failure to your router.
Wait for the update process to finish. This may take several minutes.
How to verify that your router is unlocked
Step 8: Check the router's logo and web interface
After you have updated your router with both firmware files, you need to check if your router is unlocked or not. One way to do this is to check the router's logo and web interface.
If your router is unlocked, you should see a Huawei logo instead of a STC logo on your router's body and on its web interface. You should also see a different web interface design and layout, with more options and features available for you.
Step 9: Insert any SIM card and connect to the internet
Another way to verify that your router is unlocked is to insert any SIM card and connect to the internet. You can use any SIM card from any network provider, as long as it is compatible with your router's specifications.
To do this, follow these steps:
Turn off your router and insert any SIM card into the SIM slot.
Turn on your router and wait for it to boot up.
Connect your PC or any other device to your router's Wi-Fi network. The default Wi-Fi name and password are printed on the back of your router.
Open your web browser and try to access any website. You should be able to browse the internet without any problem.
If you can connect to the internet with any SIM card, it means that your router is unlocked and you can use it with any network or SIM card.
