I'm considering starting a new thread as this is a different issue as compared to OP. I can't figure out which forum it should be in though... General maybe?

I'm also considering taking my formerly trusty old nook color outside and laying him to rest with 00 buck... which at this point would please me I think.

Uh oh!!!!!!


Very bad..

Looks like your internal partitions are completely wiped. You can re-create the partitions. However you're missing some very important unique device info which is stored in the /rom & /factory partition. You're gonna have to try and get a hold of a 'dd' of those partitions before you can go any further. Maybe someone you know that has a nook can dd those partitions for you. After that, we can proceed to re-create the partitions manually with fdisk.

There is a thread here where someone had the same issues as you did. I'll try and link the thread so you can get some info. And maybe hook up with the user, since he was able to resolve after some time.

Not sure if this will help anyone, but i also formatted boot by accident. and my nook would do absolutely nothing. luckily i had a bootable cwm sd card and booted back into CWM. then swapped out the SD card to the one i normally use. the i mounted the sd card in CWM and was able to do a nandroid restore and it restored boot and all is back where it should be.

This will recreate /system /data /cache & /media on your EMMC. This is also assuming you still have the first 4 partitions intact. This will only recreate partitions 5,6,7 & 8. Please let me know if it works or not. It should, but ya neva know. So usual disclaimers apply here..

**Use this at your own risk, I am not responsible for what happens to your device.. yadayadayada...**

Again this should work as intended, but I don't have a borked nook color to try it on.

Good luck!

Edit: Forgot to mention that all I did was use DeanGibson's scripts as a base and packaged it as a flashable zip. So big-up to you as well Mr. DeanGibson.

Thanks for that little zip file to flash that worked perfectly!!! I crashed the whole Nook when I was getting away from "Cyanogen Inc."
