The defining characteristic of the HG532e’s original firmware is that it was rarely "generic." Unlike retail routers (like Netgear or TP-Link) where a user buys a box and sets it up, the HG532e was almost exclusively an ISP-provided device.

There is no single "Huawei HG532e Original Firmware" download link because the device was never sold as a generic retail product. The "original" firmware is defined by your Internet Service Provider.
