It isn't all rainbows. The HDR1100S is newer than the old HDR-FOX T2, so the scene is slightly less mature.
This guide is based on the community standard methods as of 2024/2025. Always check the latest threads on MyHumax.org for the most recent firmware version.
Requirements:
Despite the security walls, the device was not entirely impenetrable. Over the years, a small community of developers managed to achieve a "root shell." This means they gained administrative access to the Linux command line of the box.
However, gaining root access is not the same as having a stable Custom Firmware. humax hdr1100s custom firmware
The achievement of root access on the HDR1100S was often temporary or unstable. Unlike the Foxsat, where modifications could be made persistent and reversible, modifying the system partition on the HDR1100S carried a high risk of "bricking" the device (rendering it unusable). Because the box relies on proprietary binary blobs for video decoding and the Freesat EPG, a full replacement operating system (like a generic Linux distro) is not possible. You are forced to use Humax's proprietary drivers, which are heavily tied to the stock software.
Consequently, a user-friendly custom firmware package akin to "Raydon’s Custom Firmware" never materialized for the HDR1100S. There was no simple installer that allowed non-technical users to press a button and unlock web interfaces or ad-skipping. It isn't all rainbows
The Verdict: If you are the kind of person who rips their DVDs to Plex, runs a Home Assistant server, or gets frustrated by "locked down" tech: Yes, 100% worth it.
If you just want to watch Strictly Come Dancing and chase-play the news: No, stick to stock. This guide is based on the community standard
The Humax HDR1100S with custom firmware rivals a high-end SiliconDust HDHomeRun or a TVHeadend server for cost and simplicity. For the price of a used HDR1100S (£50-80 on eBay) plus zero subscription fees, you get a multi-terabyte recorder that serves video to every screen in your house.
