Huawei implements a digital signature verification process during updates. The device checks the .bin update file against a stored public key. This prevents users from flashing "unlocked" or custom firmware (such as generic OpenWRT builds or unbranded Huawei firmware) without the manufacturer's private key. Consequently, "downgrading" firmware to exploit vulnerabilities found in older versions is frequently blocked by the bootloader.
