xda mini doens't boot

[earthphoenix]

hi,
i need serious help, and i didn't find on the forum.
my xda mini suddenly rebootet without me doing it. then the normal splashscreen came. and then... nothing, a blank screen. i tried:
1. reboot
2. remove battery
3. re-flash rom (doesn't work due to no cennection)
the MaUpgradeUt_noID.exe seems to work, but all fields are blank! and when i wanna upgrade it says "this was not built for your device. but i had exactly this rm on my device before!

what can i do?

ok, i found it.
1. hold camera and on/off-switch
2. while holding press reset (/w pencil)
3. then use ma upgrade ;-)
