Installation guide

Just place update.upt file on the root of SD card and launch Firmware update in system settings. If you want a larger font, use the bigger_font_update.upt file (don't forget to rename it to update.upt first). If you have any trouble with bluetooth connection - just disable LDAC & SBC XQ in bluetooth settings and restart your player.

Attention to Rockbox users: you must go back to the stock 1.2 firmware first!

Additional Themes

Extract .themes folder from themes.zip to the root of SD card and just switch theme in settings menu.
