Second, you need an in-circuit programmable flash. Chances are about 85%
that you have, but Archos also used an older flash chip which can't do the trick.
You can find out via Rockbox debug menu, entry Hardware Info. If the flash info
gives you question marks, you're out of luck. The only option for flashing if this
is the case is to solder in the right chip (SST39VF020), preferably with the
firmware already in. If the chip is blank, you'll need the UART boot mod as well.
8.5 FLASHING PROCEDURE
Here are step-by-step instructions on how to flash and update to a current daily build
(with the voice feature). It is assumed that you can install and operate Rockbox the
usual way. The flashing procedure is not really dangerous, and will check for correct
model, file, etc., if something is incompatible it just won't flash, that's all.
Now here are the steps:
Preparation
Install (with all the files, not just the .ajz) and use the current daily build you'd like to
have. Enable any voice features that are helpful throughout the process, such as
menus and filename spelling. Set the file view to show all files, with F1 -> General
Settings -> File View -> Show Files set to "all". Have the Jukebox nicely charged to
avoid running out of power during the flash write. Keep the Jukebox plugged into the
charger until flashing is complete.
Backup
Backup the existing flash content. You will need these files if you wish to reverse the
flashing procedure, or if you need to update the bootloader (as opposed to the
firmware) in the future. Keep them safe!
Access the main menu by pressing F1 then select Info -> Debug. Select the first
entry, View ROM contents, by pressing Play one more time. The disk should start to
spin. Wait for it to settle down, then plug in the USB cable to copy the dump file this
has just been created to your PC. The main folder of your Jukebox now should contain
two strange .bin files. Copy the larger one named internal_rom_2000000-
203FFFF.bin to a safe place, then delete them both from the box.
Copy the new flash content file to your box
Depending on your model (recorder, FM, V2 recorder), download one of the 3
packages:

http://joerg.hohensohn.bei.t-online.de/archos/flash/flash_fm.zip

The zip archives contain two .bin files each. Those firmware*.bin files are all we want,
copy them to the root directory of your box. The names differ depending on the
model, the flash plugin will pick the right one, no way of doing this wrong.
Install the Rockbox Bootloader (“formatting” the flash)
This procedure is only necessary the first time you flash Rockbox. Unplug the USB
cable again, then select Browse Plugins from the main menu (F1). Locate
firmware_flash.rock, and start it with PLAY. Rockbox now displays an info screen,
press F1 to acknowledge it and start a file check. Again wait for the disk to settle, then
press F2 to proceed to a warning message (if the plugin has exited, you don’t have
