Firmware image for a Hani DVB 407 receiver, read from a GigaDevice GD25Q32 SPI flash, with a matching 4 MB size. The GD25Q32 is a 32 Mbit serial NOR chip, so the image fits it exactly. Technicians reflash such dumps to recover set-top boxes stuck at boot, looping or with a dead front panel after a bad update. Program it with a CH341A or similar programmer, ideally removing the chip or using a test clip. Read and keep the original contents first, and confirm the board matches the DVB 407.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @afsbiosfree. Enginerys does not host this file.
