Hi BobC,
Thanks for the information!
For anyone trying to figure this problem out: I actually found a solution after some more research that works. There was a thread in this forum from 2010 (
https://www.mobileread.com/forums/showthread.php?t=97423 ) and it linked to a firmware update for the lbook (
http://www.lbook.ua/support/firmware...rom_for_v3new/ ). Its similar to your solution, cause the lbook also runs on the same hardware as the BeBook, as it is made by Hanlin. So i downloaded it and installed it and it actually worked. And this version is ADE compatible!
the correct version is: V3update-20100829-newkernel (the site is in russian)
It had some issues copying the pdf file to the reader (ADE broke down once) but it works.
Best
