[Nook Color General] ktan:
My nook color is back to 1.1.0 now. I want to say thank you to all of you guys for helping me out. It was such a great experience here and I really appreciate it.

What happened is that Joja15 helped me to create the missing partitions, and then something miraculously happened during charging: it just booted all up to 1.1.0, which I had on emmc before it got stuck. I could never have done this on my own without the help. Thank you so much Joja !

This is how it was done after you have adb working:see the original thread here:

http://xdaforums.com/showpost.php?p=13003431&postcount=166

(1) Connect Nook to PC

(2) Boot Nook into CWM off of uSD card.

(3) Verify ADB is connecting to nook by issuing the command:

adb devices

(4) If you see a serial number you are connected. Next go into adb shell by typing:

adb shell

(5) Before going any further we will want to back up your partitions 1-3 as they contain important unique information for your nook like the serial number. Make sure you 450mb of free space on your SD card.

(6) Issue the following command to backup your mmcblk0p1 boot partition to your SD card.

dd if=/dev/block/mmcblk0p1 of=/sdcard/mmcblk0p1-boot.img

(7) Issue the following command to backup your mmcblk0p2 rom partition to your SD card.

dd if=/dev/block/mmcblk0p2 of=/sdcard/mmcblk0p2-rom.img

(8) Issue the following command to backup your mmcblk0p3 factory partition to your SD card.

dd if=/dev/block/mmcblk0p3 of=/sdcard/mmcblk0p3-factory.img

(9) Once your first three partitions are backed up in adb shell go into fdisk by typing:

fdisk /dev/block/mmcblk0

(10) Upon issuing the fdisk command you should see the following:

Command (m for help):

(11) Type m to get the help menu:

m

(12) You should see the following:

Command Action

a toggle a bootable flag

b edit bsd disklabel

c toggle the dos compatibility flag

d delete a partition

l list known partition types

n add a new partition

o create a new empty DOS partition table

p print the partition table

q quit without saving changes

s create a new empty Sun disklabel

t change a partition's system id

u change display/entry units

v verify the partition table

w write table to disk and exit

(13) We will use the above commands to recreate our partition table. First lets see what our current one looks like. Issue the print command by typing:

p

(14) You should see the following but probably will not because your partition table is screwed up what is listed below is what you will want to see once you have recreated your partitions:

Disk /dev/block/mmcblk0: 7944 MB, 7944011776 bytes

255 heads, 63 sectors/track, 965 cylinders

Units = cylinders of 16065 * 512 = 8225280 bytes

Device Boot Start End Blocks Id System

/dev/block/mmcblk0p1 * 1 9 72261 c Win95 FAT32

A)

/dev/block/mmcblk0p2 10 18 72292+ c Win95 FAT32

A)

/dev/block/mmcblk0p3 19 56 305235 83 Linux

/dev/block/mmcblk0p4 57 935 7060567+ 5 Extended

/dev/block/mmcblk0p5 57 114 465853+ 83 Linux

/dev/block/mmcblk0p6 115 236 979933+ 83 Linux

/dev/block/mmcblk0p7 237 281 361431 83 Linux

/dev/block/mmcblk0p8 282 935 5253223+ c Win95 FAT32

A)

(15) We will need to first delete the partition #4 using the d command. Enter d and it should ask you which partition to delete. You will want to select or enter the mmcblk0p4 one or the #4 partition. I entered "4".

(16) Now that it is deleted we will want to create the #4 partition fresh. Issue the following command to create a partition:

n

When you enter the n command it will ask you questions like the start, the end, and the type of partition. Use the information in the print out above to enter the correct information. After you create a partition use the print command "p" to look at the partition layout and make sure that it matches the above for the new partition you created.

If it does not delete the partition and create it again with different settings until it does.

I tried this step several times before it was done in the correct way

(17) Use the n command to create partitions 5,6,7, and 8. Same as partition 4, it took me several times to get this done.

After that step I got a very similar layout as in step 14, but not exactly the same.

So I took the SD card out and planned to charge the NC. And that is when my nook color booted all up to rooted 1.1.0.

Hi, I am new here. Please talented people hear me out.

What happened to my NC is that I have it rooted by auto no, and CM7-ed, and it's been amazing. (Thanks to all of you guys!)

But one day, 2 days after RC4 I messed up somehow. Now my nook color won't boot right, it stuck at the n screen forever, if I don't hold the power button to power it off. I tried a lot of things here on this forum. Most of the time I get this error msg: can't mount /cache, can't format /system, install aborted......

So I removed CWR, then try to use the 8 interruptions plus the N+POWER key. It always give me the install failed msg after it started to install. I've tried to power it up after this and nothing changed. I have tried this for more than 10 times, crying now, any advice will be appreciated!
