Hi Terence, This may be a long shot considering there's been close to 2.5 years since the last post.... But, nothing ventured, nothing gained right? I've just gotten hold of an Elonex 511EB and would like to use it but it's firmware has never been updated. Would you by chance happen to still have the firmware for it? The dropbox link in your article no longer works (not that I expected it to... 9 years later!). I've scoured the web and couldn't find any update for this model anywhere, including the company's website, which looks like they aren't even in the business of eReaders anymore.
