1.Both exFAT and FAT32 formats are now compatible with the updated firmware, making it easier to use with large capacity cards.
2.As you no longer need to use FAT32 only, even for larger cards the need for the flayer to “Format SD” into FAT32 itself has been removed.
3.A more snappy and optimized media library update.
How to perform the firmware update:
1. Connect the SD card to the PC/Mac; the card should be in FAT32 format. Please also make sure the player has a good amount of charge remaining before starting.
2. Copy the downloaded file HMMINIFW.IMG to the root directory of the SD card. That means directly on to the card, not inside any folders. Do not change the name of the file.
3. Insert the SD card into the player and reboot the player. You will be prompted "Firmware Upgrading. Please do not operate" on the screen. Please wait to proceed. This will take a few minutes and must not be interrupted. We suggest go make a cup of tea and it should be complete by the time you return.
4. The player will reboot itself once the update is complete.
5. The file HMMINIFW.IMG will have been deleted automatically after the upgrade is completed.
6. You may now use your player as normal, leaving the card in FAT32 or you can reformat first to exFAT before filling with music.
