ok. thanks!

so what do i need to update to solve the problem?
my guess is that i need only to "touch" the PR_COMBINED_MR0_ARM.

i was looking for .bin file to use in the cmd with the flasher i found those using my code behind the battery at "tablets-dev.nokia.com restricted downloads".
so now i need to understand which .bin file to use.

do i need to use this one:
RX-51_2009SE_1.2009.42-11_PR_COMBINED_MR0_ARM.bin
OS 2009 version 1.2009.42-11 , Maemo 5 Global release for Nokia N900.

i don't need to use the "eMMC content 1.2009.41-1" where it specify also:
"Vanilla version of the eMMC content for Nokia N900
NOTE: Always flash the FIASCO image first, then the eMMC image immediately after that. Never boot up the device between flashing the FIASCO image and the eMMC image!"

thanks again.
i think we're getting a closer. this thread will be beneficial of others in the future i'm sure. i have also learned things about the internals and usage of my N900 so something good came out of this disaster... but still need to see my N900 will get back to full functioning (didn't do the flasher command yet).

just to make sure - if i will flash the 32GB memory all the data will be erased, right?
