I've written a free flasher for the n770 and n800 tablet pcs.

I have done some tests on different 770 and 800 devices and it works fine for me, but it's under development and it needs more testing and feedback. It should work on big endian architectures and other operating systems like darwin, *BSD, reactos and so

I'm planning to write a GTK frontend for it and some desktop related apps for backuping the device and so.

Help is welcome!

New version 0.5 which fixes generating and unpacking fiasco images (for N900) was released:
