The 5.2 firmware has been out for a while now, but the source code made available by Bookeen here
is still at 4.x.x. Is there a newer version of the source code available elsewhere?
The reason I'm looking for the source code is that I have the Adlibris rebranded version of the Odyssey, which is still stuck at 4.0. It's tivoized, so simply installing the normal firmware doesn't work. Chances are the lock is located in the bootloader, in which case I'm screwed. If, however, the lock is in software, I may be able to circumvent it if I have access to the source code.
