[maemo-users] Flash to Death?

[From: Jan]

Hi list,

now I am also a happy user of a N800. So I played a little bit with it and 
managed to have a mmc dual-boot system, and so on.

But I am a little bit unsure about flashing my N800 to death. So my question: 
Is it possible to patch/flash the N800 to death, so that the only option is, 
send it to Nokia for repair.
And if so, what should I NOT do.

Thank for Help
Jan
