I ran the autoinstaller and booted to nitdroid, but then it crashed. There was this text : "kernel panic", and something else can't remember what it was. Tried to boot to power48 and the stock kernel but they didn't work. Then tried to flash only the kernel from rootfs image but n900 still didn't boot. Just a minute ago tried to flash the whole phone and I started with the eMMC but it somehow lost connection and there was text : Booting device to flash mode and then it said waiting for suitable device.

So, I'm kind lost now what do you suggest? Thanks in advance !
