thanks for the help

I held home & tried the different options like boot to flash.. / internal / ext (which say not found, booting from flash" >>
first option / default "booting from flash (mtdblock4 jffs2)... "
is in a reboot loop.

I tried with and without my SD card in there.
only way to shut off is remove battery.

maybe worth trying ubuntu liveCD on home pc, and see if mem card is recognized?

worst case is I have to reflash and install essentials.. which im getting used to.

Did I make a mistake when partitioning the 8gb, by leaving the partition too small? the one recognized as the n810's internal with mydoc's and all that? .. apt-get was putting files in the user folder on there.. and when dpkg -i somefiles it said no space error.. the drive was otherwise totally empty except for some files that had been apt-get, and they weren't taking too much space..

other than that, i had a shitload of apps installed via application manager
