okey so I did adb devices and I only get zeros, the problem is though I couldn't pull partition 5 from my nook because the partition table was completely destroyed (and as far as I know partition 5 has the serial number and the mac adress in it)

EDIT: so I tried to install CM 7.2 which was succesfull. Then I rebooted my nook and it goes into CWM (internal).

EDIT2: just tried the recovery bootloop fix and it didn't help

Ok i know about this one and it might help. Flash stock 1.4.2 recovery and then run the stock 1.4.2 update.zip from sdcard. More info in my thread where it says ATTENTION 8GB USERS but works for 16GB aswell.

Did you take out the microsd card? Dumb question but yeah.

Okay, I see the problem:

EDIT3: so after doing your tutorial my partition table looks like this:
Partition Table: gpt

Number Start End Size File system Name Flags
1 131kB 262kB 131kB xloader
2 262kB 524kB 262kB bootloader
3 524kB 16.3MB 15.7MB recovery
4 16.3MB 33.6MB 17.3MB boot
5 33.6MB 83.9MB 50.3MB fat32 rom
6 83.9MB 134MB 50.3MB fat32 bootdata
7 134MB 522MB 388MB ext4
8 522MB 1164MB 642MB ext4
9 1164MB 1611MB 447MB ext4
10 1611MB 14.5GB 12.9GB fat32 media
11 14.5GB 15.9GB 1443MB ext4
Boot is a secure partition that's supposed to start at 16.8mb not 16.3mb

Hmm...hmmm... Try doing "dd if=/sdcard/blk/genptable of=/dev/block/mmcblk0" one more time. And then repost your partition table.

Yes, you can still run CWM from sdcard. It's probably the best thing about the nook amirite.

Hmm. You can't. Because parted will automatically revert it back to 16.3MB.

Try the process again, but this time dd genptable before you create the partitions, then create the partitions with sgdisk and let me know what it says.
