Firmware is an integral part of any device and without the firmware, the device does not work. Some devices come with un-customized firmware, means after changing the default SIM card with any another network provider SIM card, it can be easily unlocked. If the device has customized firmware then without changing the firmware, unlocking is not possible. Some devices come with un-customized firmware but customized software or WebUI, means after changing the default SIM card, it does not ask for unlock code but can be unlocked with a third party tool or with the help of putty.

To change the firmware, you need a flash or firmware code, which can be generated through a universal master tool.

If you are trying to search a firmware update of your device, then you must know the previous firmware of the Huawei device. In this post, we will try to check the firmware version of the different Huawei modems, and routers.
