Firmware — Humax Hdr1100s Custom
Report: Analysis of Custom Firmware for the Humax HDR-1100S
Date: October 2024
Subject: Capabilities, risks, and user value of unofficial software modifications.
For General Users:
Do not attempt to install custom firmware on the HDR-1100S.
The benefits are minimal, the process is fragile, and you risk losing all recordings. Use the official software – it is stable and supports external USB recording backup (still encrypted, but restorable to another HDR-1100S). humax hdr1100s custom firmware
Minimal example: boot a Debian rootfs from USB (conceptual)
- Prepare USB:
- Partition 1: FAT32 with kernel and initramfs
- Partition 2: ext4 with Debian rootfs (debootstrap or extracted rootfs)
- Configure initramfs or kernel cmdline to pivot_root to /dev/sda2 (root=/dev/sda2 rw).
- Interrupt U‑Boot, set:
- setenv bootcmd 'ext2load usb 0:1 0x2000000 uImage; setenv root /dev/sda2; bootm 0x2000000'
- saveenv (only if you want permanent)
- Boot and debug via serial; fix modules, device nodes, and services.
(Adapt commands per your device’s bootloader syntax and storage mapping.) Report: Analysis of Custom Firmware for the Humax
Loss of Freesat Features
Some firmware modifications break the "Freesat" certification handshake. This means: Prepare USB:
- You may lose the ability to rewind live TV (timeshift buffer).
- Red Button interactive services may stop working.
- Automatic channel updates (e.g., when BBC Four HD moves frequencies) will fail. You will have to manually rescan.
4. "Sweeper" – Automated File Management
Sweeper is a scripting tool. You can tell the Humax:
- "If a recording is older than 30 days, delete it."
- "If a recording title contains 'News', move it to the 'News' folder."
- "If disk space is below 10%, delete the oldest watched file."
