H3Mod is a tool to modify images in firmware files for the H300 (since 2.0 also H1xx, and with the newest patch, the decoded BL_H10.ROM file for the H10 series) series of iriver products. It comes with a set of predefined bookmarks, but also allows to search for yet unlisted images and change these, too. It is also possible to search and modify images in any other binary file, as long as the pictures are not bigger than 220x176. (H3Mod website )

What H3Mod can't do[]

  • Change the size or number of colours of a picture
  • Use videos or animated GIFs
  • Change the colour or background colour of fonts. Absolutely definitely not. Don't even

think of asking me or mistic.

  • Restore the settings (tuner region, language, EQ etc) of the firmware. After an

upgrade. it will always have the default settings.

  • Change anything else, like supported video types, features...
  • Change firmware of other iriver players. PMP looks vaguely doable, but requires
