Hi again,

Strange ... the reason is "32wd_to", so the watchdog timer actually
always killed my N770 - so its actually a bad test case wether the mmc
card is evil ;)
Maybe it even crashed the other times becaus eof this reason :-/

./flasher-2.0 --enable-rd-mode --set-rd-flags no-lifeguard-reset

help with this? would I loose any data when executing the command
mentioned above?

Thank you in advace, lg Clemens
