Humax: Firmware
1. Introduction Humax is a major manufacturer of set-top boxes (STBs), PVRs, and digital TV receivers (e.g., Foxsat HDR, HDR-FOX T2, Aura, and various operator-branded units). Their firmware is typically Linux-based, running on MIPS or ARM SoCs (Broadcom, STMicroelectronics, HiSilicon).
scripts/extract-ikconfig kernel > config.txt U-Boot often unlocked via UART. Interrupt autoboot with Ctrl+C or Space . Commands: humax firmware
dd if=firmware.hdf of=rootfs.squashfs bs=1M skip=4 unsquashfs rootfs.squashfs Some Humax firmwares use a repeating XOR key (e.g., 0x55, 0xAA, or a fixed 16-byte key). Detect with: scripts/extract-ikconfig kernel > config
dd if=firmware.hdf of=kernel.lzma bs=1M skip=1 count=3 lzma -d kernel.lzma file kernel Check kernel config: Detect with: dd if=firmware
For serious work, always keep an original firmware dump and a JTAG recovery method. Humax boxes are robust, but a bad flash can brick them completely. Would you like a focused guide on a specific model (e.g., HDR-FOX T2, Foxsat HDR, or Aura), or help extracting a particular .hdf file you have?
binwalk -X firmware.hdf Then decrypt:
binwalk HDR_FOX_T2_1.03.12.hdf Example output:
