@thomass: - this error is probably because the update_duokan_0xxxx.bin remain in the root directory.
This file was automatically removed during an successful install. It makes Amazon OS think there is one of theirs.
About usbnetwork: Duokan has used this all the time, but it is rather messy to have it in Chinese

Their use of it, is limited to accessing the bookstores.
@joshualintag: "How did you edit the ebook3.img?"
I did not really do that. Have intalled new hard-drives, and I would have to check the old drives. Another fellow posted
an modification. Search the thread-postings on this site and you may find it.
( I did give it a go, but choosed to await the situation. )
@kelbek: no 3G available.
@wizkoder: there are many post on dictionaries, howto install and use them. However, depending on your
