Firmware dump for the Huawei HG532e ADSL modem router, a 4 MB flash image delivered in a 3.50 MB RAR archive. Repair shops use such a full image to recover a unit that is bricked after a failed firmware update or stuck in a boot loop, writing it straight to the SPI flash chip with a programmer like a CH341A. The chip capacity must be 4 MB for the image to fit. Save a copy of the current contents first, because settings and identifiers such as the MAC address stored in flash can differ from unit to unit.
