Ok, can you still get to fastboot? If so, here's how to proceed, carefully.
If something doesn't react as portrayed, stop!
Preparation
Download
http://su.barnesandnoble.com/nook/pi...1/gentoo/3.123
Download nnglow21.img from
http://www.temblast.com/neonoogie.htm
Get misc-rec.prc from attachment. Just rename it plain misc-rec
Install rooted recovery
Go to fastboot:
Code:
C:\>fastboot flash recovery nnglow21.img
C:\>fastboot flash misc misc-rec
Long power press to reset, you should see a splash with "Neo Noogie".
Install update
Code:
C:\>adb shell
# mount -t f2fs /dev/block/by-name/UDISK /data
# mount -t ext4 /dev/block/by-name/cache /cache
# ^D
C:\>adb push update.zip /data/media/0
C:\>adb shell
# update-binary 2 1 /data/media/0/update.zip
<lots of printing, should end happily>
# dd if=/dev/zero of=/dev/block/by-name/misc
dd: /dev/block/by-name/misc: write error: No space left on device <not a problem, correct>
^D is control key + d
Hit the power button (which has "Reboot normally" written under it)
If that doesn't work do a really long power press ~30 seconds.
