How to upgrade (official ReadMeFirst instructions)
- Windows 10: just connect the unit to the computer. If the computer is connected to the internet it installs the drivers automatically; wait until the process completes, then use the 3.9.2 directory.
- Other Windows versions: install the Silabs driver first if it is not yet on your system.
- Connect your Integral 2 to the computer via USB, run the MCU&FPGA update file, and you are done.
- After the FPGA update, power-cycle the unit and wait about 15 seconds until the update is applied. The ReadMeFirst notes that the unit is ready to operate once it lights back up.
- The updated version must show 2.40.2.45 from the OSD or GUI.
- If a lock icon appears in the top-right corner after updating: hold RST and press INP 2 times. The unit prompts for a power cycle; after completion and restart the lock is gone and the unit operates without limitations.
Note: the official ReadMeFirst mentions an OLED and the Vertex by name in two places — those lines are shared boilerplate across HDfury release notes. The steps above apply to the Integral 2 as published in its own firmware package.
Firmware version history (official release notes, 1:1)
Newest first. Quoted verbatim from the official HDfury ReadMeFirst; version strings and feature names are left in English on every language version of this page, because they match what the GUI and OSD literally show.
2.40.2.45 / GUI 1.34 — latest
- Fixed a RS232 bug in Matrix mode
- Unlock as per usermanual p.13 no more needed from that release.
2.38.2.45 / GUI 1.34
- Fixed a condition when input is 4K50 420 and downscaled to 1080p50, Wrong VIC code was presented at the output.
2.38.2.44 / GUI 1.34
- Added X1X LLDV detection fix for LG TV
2.38.2.43 / GUI 1.34
- Added MuteBot Output Audio ON/OFF IR codes support.
- Updated IR codes list.
2.37.2.43 / GUI 1.34
- Improved autosense routines which would convert in some case to deep color even if input is not deep color. Modified and improved autosensing throughout direct paths, upscaling paths and downscaling paths.
- Updated input routine for 4K24 422 12b and 4K60 422 12b now supporting more sources even if their timing are slightly off.
2.37.2.41 / GUI 1.34
- When HLG is input but the display does not support HLG then conversion to the current custom HDR string automatically.
- GUI selection has two new checkboxes. When HDR10 is input Vertex can automatically replace with the custom metadata. Same thing with HLG input (regardless if display supports it or not)
- Fixed issue in autoscaling when sink edid was an old version with HDMI vendor specific string too short, autoscale was decoding value that were not present.
- Fixed Custom Scaling issue that prevented upscaling when sink was max 300MHz and does not contain scramble registers.
2.37.2.37 / GUI 2.33
- Release version
GUI numbering note: the ReadMeFirst release headers list “GUI 1.34”; HDfury's official product listing refers to the current Windows GUI as 2.34. Both numbers are reproduced here as published rather than “corrected”, since we only quote official sources.

Always confirm you are installing the driver version that matches your Windows version and USB port type before flashing firmware — see the manual for the exact matching rules.
How the firmware update works
Both an FPGA update and an MCU update are required to fully upgrade the unit; there is no required order, but starting with MCU is convenient since it does not force a mandatory power cycle. FPGA flashing takes about 50 seconds and requires a power cycle afterward (no lights for about 15 seconds while the unit reconfigures); MCU flashing takes under 5 seconds. Full steps are on the manual page.
