The Vodafone M028T (often branded as the Huawei K5160 or similar inside) is an aging 4G LTE mobile hotspot. Downloading firmware for it is technically possible, but the process is fraught with danger, poor official support, and minimal rewards. Only attempt if the device is bricked or you have advanced technical skills.
Many users seek firmware downloads to "unlock" the device, allowing it to work with non-Vodafone SIM cards. This is a more technical "flashing" process. Drivers: WTPTP and LTE generic drivers. Flashing Software: SW Downloader or specialized MiFi tools. vodafone m028t firmware download
