My NC is one of the originals, more than a year old, has been flashed to CM since it came out, and until recently was running CM7.1 stable. Then one day a few weeks ago the graphical screen lock pattern wouldn't work and after too many attempts when google asked me to put in my password I could not because the keyboard (swype) wouldn't come up to let me enter it. (I NO LONGER PUT PASSWORDS ON MY ANDROID DEVICES NOW!!!). So I powered off, and it hung powering up. So I rebooted into CWM and tried to flash a backup which threw me into a boot loop. So then I wiped data, cache, dalvik cache (never formatted anything else, I am 100% sure), and reflashed CM7.1 and it was dead.
Currently I have tried many many recovery methods to no avail, have tried to flash back to stock to no avail. The NC will only power on with a SD card inserted no matter what button combo I try.
I installed ADB and this is the output:
~# fdisk -l /dev/block/mmcblk0
Disk /dev/block/mmcblk0: 7944 MB, 7944011776 bytes
4 heads, 16 sectors/track, 242432 cylinders
Units = cylinders of 64 * 512 = 32768 bytes
Disk /dev/block/mmcblk0 doesn't contain a valid partition table.
Back in the day I rebuilt many a partition table on many an old PC, and plenty of computers that existed before the PC, and all kinds of other weird stuff, but I can't find a way to do it on this NC. After long hours of search, I think the above means that my nook is done and it is ready for target practice, is that correct?
