The last regular firmware version of the FiiO X3II digital audio player is 2.0 at FiiO's site. An interesting previous version is 1.4, the last with OTG support (adding storage on the USB port, which is not officially supported but works for most).
FiiO allows the firmwares to be customised with alternative images and graphical properties (colours, font sizes...). FiiO shares instructions on how to customise a firmware, how to install a firmware, and its own large text font firmware. Here are some public firmware variations shared on Head-Fi:
Off the shelf firmwares
Arielp's big font
Zweistein's high-contrast, bold font
Shared on dropbox. All themes have larger playtime and track numbers (the ones below the progress bar).The themes are:
- White/green on black
- Same as 1 but with the traditional line as progress bar
- White/orange in slightly bigger font, with watery progress bar
- Same as 3 but with pacman progress bar
- Same as 1 but with a big font - the biggest that still shows all letters completely
- Same as 1 but with an even bigger font - cutting off the tail of lowercase letters g, j, p, q, y.
