well, according to this :
http://www.aximsite.com/boards/x50-x...-flashing.html thread, i can flash my device, if i have : a DiMa_WM5-bootloader (a bootloader from WM2003 to flash WM5 and a WM5 image. i have both and i'm thinking about flashing.
but i still got 2 questions :
what is the 'action-button'? is it the tiny button in the middle of my 4way-movement/navi-keys?
and can i flash any rom back, if something goes wrong?
