Hello,
You do this by having an EPROM burning program or module. I used to do this in my Atari 800 days and had a stand-alone interface that allowed me to reprogram the EPROM. That is how they place the first initial firmware at iRiver's factory. You also can bridge two pins that come out of the EPROM to enact a clearing of its memory locations and their corrupted memory contents.
The truth of the matter, is...that there is no such
true thing as a 'bricked' (ie: fatal, non-recoverable state) EPROM-based device. It is never permanently damaged unless by a voltage spike, or E.S.D. (Electro Static Discharge) damage. You only need to clear the EPROM as I have stated, and download your firmware back onto it from its virgin state. Never throw away your DAP if you have 'bricked' your player. Send it to Iriver or take it into a repair depot that has an EPROM download module (hardware) along with a copy of your BIN file (firmware) and they can easily do it for you. When the consumer 'bricks' his/her player with a firmware download failed attempt, all that has happened is that they now have a corrupted and incomplete PARTIAL programming on the EPROM and again, that can be EASILY corrected with a clearing and reprogramming of said EPROM.
Cheers!
