so, I'm setting up dual booting, but didn't get it quite right, and needed to put the sharp kernel back. I used cortez's updater.sh, put the zImage.bin onto the memory card with it, and kicked it off*
it flashed the kernel no problem. when it said "format hard drive" I hit CTRL-C, no effect, so then I typed N and hit return, and it proceeded to format the hard drive. ARRRGHHH!
sigh.
