Hagibis MS2130 Sharpening Disabler Patch

A firmware patch for a Hagibis-branded MS2130 HDMI-to-USB capture dongle. It disables the chip's built-in sharpening filter, which adds visible halos around text and other high-contrast edges. The patch changes only the sharpening setting — scaling, supported resolutions, and frame rates remain unchanged.

Flashing

  1. Build the cli utility from BertoldVdb/ms-tools.
  2. Back up your existing firmware: ./cli --log-level=7 read FLASH 0 --filename=backup.bin
  3. Write the patched firmware: ./cli --log-level=7 --no-patch write-file FLASH 0 /path/to/hagibis_ms2130_patched_nosharp.bin
  4. Unplug and reconnect the dongle once the write completes.

To restore your own backup, use the same write command with the file you read from the device: ./cli --log-level=7 --no-patch write-file FLASH 0 backup.bin
