Fon Flash is a new program based on AP51 flash, for flashing La Fonera and Atheros chipset compatible devices. It has been tested, and works with the original 2100/2200 devices, as well as the newer Fon+ and Fon2.0 models.

The primary improvement in Fon Flash over AP51 flash is that it can flash several different types of firmware. While AP51 flash is suitable for flashing Gargoyle / OpenWrt, it cannot flash the latest official Fon NG firmware which requires three files to be flashed to the device, or the latest releases of DD-WRT (v24 and v24sp1) which require only one file. Fon Flash can flash all of these configurations.

Summary of improvements over AP51 Flash:

1. Can Flash Fon NG and DD-WRT as well as Gargoyle/OpenWrt
2. Now works on Mac OS X as well as Windows and Linux
3. New cross-platform GUI, works on all 3 platforms
4. No longer consumes 80% of CPU resources, like AP51Flash
