I've got an email in to Kurzweil, but thought I'd check here too. I know they're busy with the PC4 rollout.
Anyways, I pretty much bricked my LE by accidentally formatting the flash. No objects, sound - nothing but a boot loader screen.
Diagnostics all show OK, but if I try to load the OS files, I get some kind of "usb device not supported or not present" message.
The bootloader screen shows a different version than what the 2.27 download instructions shows.
So I thought maybe if I could try 2.26 instead, it might do something. But it's not on Kurzweil's site.
So if anyone has it, maybe you could post it up or pm it to me or something.
Edit: forgot to ask if anyone has run across a listing of compatible thumb drives for the LE.
Reading in their knowledge base, it says there's only 100ma power available for them.
But thumb drives usually don't list the power they require.
Update and for future reference - it took me two days, but I got the files loaded.
Tried unzipping, formatting, deleting everything but the required files, researching usb drive power requirements, taking the board apart to look for loose connections/broken wires, and so forth.
Not sure what exactly did it, but I formatted a fresh, small (8 gb) PNY drive (research showed they had low power requirements), left the files zipped, and those were the only files on the drive, each separate (not in a folder), and the board finally recognized and loaded the files.
Life is good. 
Can't wait for the PC4.

Walk around the directories for other models, too.
