[Q] Cannot Format /Data

Whenever I try to format /data through CWM 3.0.2.8, it returns the message.
error while formatting /data

Click to collapse
Also when I try to restore a backup, CWM cannot format /data.
I've also tried to install CM7. It says it completed its install in CWM but when I reboot, it retains the OS (rooted stock 1.2) I was currently on.

Me too. I just updated to MR1 and I am trying to restore the /data directory and I can't.

There's one thing I noticed about this refurb'd nook color. The space available in the device info is 1GB. Shouldn't it be higher or did they change the file structure with the latest models?
Also, I went into ADB and mounted EMMC. The last modified date for the files in there is May 4th.
Edit
Not sure if this would help.

Someone responded back to me on this forum.
http://androidforums.com/b-n-nookcolor/333668-format-internal-partition.html#post2672750
Barnes & Noble has started shipping new NOOK Color devices that are partitioned to allow only 1 GB of "user sideloaded" storage. The remaining 7 GB are partitioned for the OS, apps from the new B&N Apps store, and items downloaded directly from B&N. For the typical (non-rooted) device, the user would have to use the microSD slot for additional storage. I suspect you got one of the newly partitioned devices, which is why you are now seeing only 1 GB instead of the previous 5 GB of storage available.

Is there anyway to repartition the new devices or I'm stuck with this? If not, it's going to prevent me from dualbooting. This might also be the cause of my second problem, installing CM7 and still ending up with the original OS.

Oh man am I glad I found this thread. I was freakin' out when I couldn't load phiremod onto my newly purchased NC. Turns out I can only see 1GB of storage like the others in this thread. Hopefully some one will find a way to repartition the newer devices otherwise I am stuck with a rooted NC running the stock ROM with no way to return it.

You can just "Reset to factory default" and it'll remove the root. Then you can try to return it or exchange it. I'd probably say this if they ask for a reason...
"It's showing 1GB space as opposed to 8GB space as advertised"
Though I'm wondering why install CM7 doesn't change anything. After installation, it still boots up the stock OS.

Trying to load new ROMS fails because I can't do a data wipe as instructed.

I wonder if they made it so that outside sources can't write or modify /data now but it's still rootable with manualnooter.. I can format the other partitions through CWM and restore them easily.
EDIT
http://www.barnesandnoble.com/nookcolor/features/index.asp?cds2Pid=35583
*1GB = 1 billion bytes; Actual formatted capacity may be less. Approximately 5GB available to store content, of which up to 4GB may be reserved for content purchased from the Barnes & Noble NOOK Store.

I am not sure what kind of security they could have on the actual partitions, but the dual boot ROMS show that resizing the partitions should not be to hard, though it does mean you may lose data (possibly).

I don't mind losing my /data. I rather be able to install CM7 or something on the EMMC as opposed to running it on the SD.
I'd be grateful if someone could show me how to partition it so it's back to the original partition, 4gb/4gb as opposed to 7gb/1gb I think.

I hope something is figured out soon.

Here's the solution to anyone following this thread.

I had this problem too.. bought a brand new nook color... this is what i did using CWM 3.0.2.8 to boot off SD...
1. used manual nooter 4.5.6
(after applying had all types of popup force close messages about /media this /media that)
2. changed my patitions to match this post
http://forum.xda-developers.com/showpost.php?p=13003431&postcount=166
(Note: Although it said that it didnt write the partitions it actually did)
3. did the 8 boot reset and nook button reset...
(This didn't reset the partitions actually and I had 5.sumthin GB free space not 1GB as before)
4. Manual nooted again then installed Phiremod 6.2 and Dalingrin's Kernel 042411 for cm7....

I did this too and it scared the crap out of me when it kicked me out of fdisk. I thought I hosed it for good. Then when I did the 8 resets it kept going into CWM on the 8th reset. It wasn't until I rebooted it from CWM did it go and reflash itself.
Man that was scary. I thought I had a $250 paper weight.

I was a little freaked out when the fdisk said it didn't work... But reading around I seen that its almost impossible to break it as long as you don't mess with the first 3 partitions so what was the worse case I figured... This must be an issue with the CWR though.. Probably just updating the CWR to format different sizes of the partitions... A format with offset and length feature in an advanced menu... then we can change the sizes to what we want.. But going forward until CWR gets updated every new nook probably gonna have to do the partition change... Not like that's a big deal...

I bought a Nook Color used off craigslist cus they "bricked" it. I thought, no prob, through in the CWM uSD card, erase the data and system, and throw 1.2 on to root.
Can't erase the Data!
They said it was only a few weeks old. I'm guessing it was a refurb with new partition, they tried to root it somehow, and messed it up, then gave up.
Let's hope this fixes it!

Let us know if the partition thing works.. that would be cool.. GL.....

[Q] How do I partition the eMMC to support Custom ROMs?

I bought my NC last week and immediately rooted it with out a hitch using ManualNooter for stock 1.2. In the process of trying to flash Phiremod my NC locked up in CWM when doing a wipe data/factory reset as instructed. I did a hard reset and tried to load Phiremod any way, which failed. I ended up using the backup I made of the rooted clean stock OS and it is working.
I read this thread
http://forum.xda-developers.com/showthread.php?t=1077973
and mine has the same issue of a partitioned eMMC that only reports 1GB. This prevents me from loading custom ROMs and side loading any applications.
One of the posts on that last thread mentions how dual booting essentially repartitions your eMMC to allow for the said dual booting, so I tried the "Step 1" in the repartition process here...
http://forum.xda-developers.com/showthread.php?t=959461
And it failed, but did boot back into my stock rooted OS.
My question is...
Is there a way to repartition my NC with what seems to be a new partition scheme that B&N moved to so that I can load custom ROMs, sideload programs, and/or dual boot off of eMMC?

Would like to see this answered as well.

grab your oars....
I'm in the same boat.... I have the 1 gig partition on my new Nook.
I can boot from SD ok but I would rather blow out the stock and save my SD.
Help?

Anyone out there can help us repartition the newer nooks?

side load partition 1 gb on newer NC's
guys check this out. I am doing it now and will report back after I get this done.
http://forum.xda-developers.com/showthread.php?t=914690
boot repartition with stock 1.0.0 or 1.0.1, then side load 1.2 update from b&n site:
http://www.barnesandnoble.com/u/nookcolor-support-software-update/379002520/
If I read all this correctly.. this should do the trick. as well as re-enabling apk installs correctly with rooted stock?

Already tried that.
You'll get a 1.0.0 or 1.0.1 with 0 Space available and you cannot sideload because of that. All that does is re-write the folders and not partition it.
I even tried changing the factory.zip with an older version in the /emmc and did a system/data wipe through the 8 boot fails and power + n reset.

One possibility

If you are familiar with fdisk and mkfs.ext2 or are willing to learn, and can boot a rooted OS from the SDcard, it should be trivial to delete, resize, repartition, and reformat /data (0p6 -- ext3), /cache (0p7 -- ext3) and /media (0p8 -- vfat). Do note the size of the partitions (especially 0p7/cache) before deleting them.
Then, when you restart the NC, it should recreate the contents of /data and /media to virgin content (meaning you better have backed up any non-B&N content). You will have to reregister with B&N, so you should probably do this on an UNROOTED Nook.
This is an experiment that I have wanted to try, but have not had the time; I've been too busy doing other experiments, like having B&N do the intentional repartitioning. I was using internal dual boot before, but uninstalled it before the repartitioning, because I knew there would not be enough space for dual boot afterwards.

I'm just unfamiliar with the block sizes and the commands to partition/change it.

Dear God I would love to try but honestly I don't know a think about command line linux. Also, mine is already rooted, but I can always take it back to stock.
If someone gets this to work please document the process. I would really like to be able to use the internal memory for custom ROMs and be able to side load programs.

Anyone that can help us?

[Q] Unable to back-up nook touch

I just bought a nook simple touch and i want to start playing with it, but, before i do this, i want to make sure i have a backup for it.
My problem is that i am unable to see the hidden partiton (the large one). I use ubuntu linux, but i also tried looking for it on windows, following the instructions from this link.
the df -h output is:
Code:
[email protected]:~$ sudo df -h

/dev/sdb 237M 82M 156M 35% /media/NOOK
and of course, when i create the image using dd, it looks like this:
Code:

239+1 records in
239+1 records out
251641856 bytes (252 MB) copied, 15.2308 s, 16.5 MB/s
on windows, also, Roadkil's free DiskImager also sees just this small partition.
there probably is some protection b&n set on the device, but couldn't find any post related to this issue.
my model number is BNRV300
What options do i have?

Use Roadkil - backup the physical disk not the partition - this will of course depend on the number of drives you have - on my laptop it is disk 1 1.86G

as i said, roadkill doesn't see that partition either

Are you booting from a sdcard with noogie (is rooted forever written on the screen)?
If you just boot normally you can only access the media partition and the sdcard.

oh, so this is it... no, i didn't boot with noogie. i booted it normaly. seems like i missed that step. will try with noogie. many thanks!
L.E.: i just figured out why i missed that step - the nookdevs.com site is down so the link didn't work. any reliable source to get that image?
Thanks

Looks ok.
Happy hacking

ok, so i was a bit skeptical about the image because i encountered some problems while doing it so i started over.
i'm having some problems with dd when i'm writing the images. before writing the noogie image using dd in linux, my microsd looks ok in gparted (with fat32 filesystem)
After doing this:
Code:
[email protected]:~/Nook/Nook-touch-rootkit$ sudo dd of=/dev/mmcblk0p1 if=noogie.img
155648+0 records in
155648+0 records out
79691776 bytes (80 MB) copied, 35.8831 s, 2.2 MB/s
it shows unknown for file system and cannot be mounted anymore...
the image i used before (to get the output from the previous posts was created on windows with roadkil, but now that doesn't work either.
microsd is class 4
what could be wrong? if i write other images to the disk everything is ok, but the images to root the nook do not work.

afaik the noogie image is in superfloppy format (no partition table, only the filesystem) and thats why gparted doesn't recognizes it.
But the sd-card with the noogie image on it should be mountable on windows and linux (its fat32).
Maybe you could try an other cardreader.

this is very weird... i managed to write the image to the card using "ImageWriter" (aplication for linux) which i think runs the same code i run in the terminal... i don't get what's wrong...
because if i'm doing something wrong i can't be sure that my backup image is ok.
L.E.: my image is ok, just tested it after messing up the rooting process

I think your problem is, that you should write the noogie image to /dev/mmcblk0 and not to /dev/mmcblk0p1 (on the sd-card, NOT on the nook itself).

Question how do I write the noogie image to the SD card with windows??
As said already I looked at the backup thread as said by previous poster but the link is not working.
I did get the noogie image from the other link provided but how do I copy/write the image to the SD card in windows.
Thnx in advance
Edit:
I think I found something in an other thread, they use this program (win32diskimager) to write a .img to a SD card. Will try this one out.

I used this program win32diskimager to write noogie.img to sdcard in the following manner:
- Select noogie.img as "Image File"'
- Select SD card as device
- Click the button "Write"
Then I waited untill it was finished. Put SD card in Nook Touch, started up the Nook, but no screen with "Rooted Forever" showed up and if I continued with the next step, trying to make a copy of the the Nook partition with Roadkils DiskImager then I could not see the 1.82GB partition of the Nook.
Can someone help me on the way.
I started the Nook but did not yet finish registration before I tryed the above. I was in the middle of registration, but decided to make a backup first, so switched off the Nook and did what I described above (my idea was that after the backup of my Nook to skip the registration, as described somewhere else and then root the Nook).
Hope someone could give me some answers.
Edit:
Indeed when I skipped the registration and again booted from the SD card previously made with the noogie.img I got the "rooted forever" screen and I was able to make a backup of my Nook partition. Thnx a lot everyone for making such nice descriptions, OK now try to root it.....

CAn you please expand on how you got the nook to boot from the SD card (any special key presses?) I managed to write the noogie image on to an SD card. Inserted the card in the nook. Powered it down and then back up again, but didn't see any option to boot from the card. Not sure If I've missed something here.
Thanks in advance

If the img file is written correctly to the SD-Card the nook will boot from the SD-Card. No need to press anything.

I cannot get noogie image working too. Have the img "burned" to SD card. Tried 2 different cards 4GB class6 and 8GB class10.
Tried to power on connected or disconnected from PC, Nook just starts up normally and then claims SD is not recognized and should be formatted.
Any ideas?

It's quite simple really, the Noogie.img weren't correctly written onto your SD card.
There can be several reasons for this, but most likely it's your card reader.
I.E. the built in card reader on my old HP Pavilion doesn't support raw access in a proper way and I had to buy an external card reader for it to work.

Hey I'm having a similar challenge as arvindar_n...
I just got a new nook simple touch and am looking to back it up.
Doing a google search lead me to the Backup/Restore N2E post.
The instructions say to:
1. Boot nook with noogie.img : (the "Rooted Forever" screen) and connect to your computer via USB.
2. Use DiskImager to copy your Nook partition to a file, being sure to select "Physical Disk" in the drop down list.
Step 1 seemed to work, I used winimage and wrote nookie.img onto a sd card
I put the sd card in the nook, let it reboot and was greeted with the "Rooted Forever" screen but it just sits there...not sure if that's the first problem.
Step 2, using DiskImager, I'm suppose to select Physical Disk. The challenge I'm having is there are 0-7 Physical Disks! My confusion is that none of the sizes are the 1.82 partition I'm reading about. I can see a 239.98 and 120.08 but no other physical drive besides my regular disk drive.
Please advise!

Unable to to Boot after CM7 install

A friend of mine tried to install CM7 on his NookColor. Something went wrong and so he brought it to me. I've done dozens of these. I thought it would be an easy fix so I stuck in my trusty SD boot card with encore_CM72-MiRaGe-03042012. I booted into CWM and did a factory reset and installed encore_CM72-MiRaGe-03042012. I booted it up and expected it to be fixed.
It did the same thing this time which is to boot to the initial splashcreen and then go blank. You can tell the screen is still backlit, but it never changes. You have to hold the power button for 30 seconds to turn it off.
When I boot back into CMW I see some unexpected messages
E:Can't mount /cache/recovery /command
E:Can't mount /cache/recovery /log
E:Can't open/cache/recovery /log
E:Can't mount /cache/recovery /last_log
E:Can't open/cache/recovery /last_log
I tried installing CM7 again and watched the messages closely. It says
Installeding update
Install from sdcard complete.
Reboots the same way
Can anyone point me in the right direction to fix this? Thanks

Well, I spent all day yesterday Googling and searching all the forums on XDA Of course I started with Dummies Guide to Fixing 'My Nook Won't Boot'. It is incredibly out of date and is likely to do more harm than good. I think that if it is going to be a sticky, then at least it should show current, relevant information.
I tried [HOW-TO] : Restore Nook Color back to stock EASILY!. I was unable to format several of the partitions specified, but proceeded anyway. It appeared to install OK, but now I am stuck at the N when it boots.
I am continuing to search but I keep running into dead links, downloads that say they will take 5 hours, and references to outdated files. I really would appreciate some knowledgeable help here guys. Thanks

I have the same deal. I think since the WIP clockwork update. I've tried most of the fixes from the links as I still have most. I tried everything you have as well as trying restoring and using different versions of clockwork and trying to get a cache up to no avail. The please keep me posted because this is the first replica of my situation. I am using an Asus t101 now so I'm in no hurry but I've had me NC forever and love the reading size.
Good luck.
How do you create or fix the cache for e:? I can you ADB into clockwork?

Just in case anyone ever reads this thread I thought I would give some more information regarding my problem.
I am able to get into CWM 3.2.0.1 internally. I stiil can't get any ROM loaded though. ( I have loaded several different ROMS to the NC previously including the CM7 nightlies from 75 to 130, so I am well versed in how to do it).
I'm thinking there is something wrong with my partitons. I'm not well versed in exactly what happens during the boot process and what is on each partiton.
I though it might be useful for those people who know about this stuff if I supplied more info (since my eyesight is giving out from reading so many threads)
If I go into the mounts and storage menu and do severals format, this is what I get.
Format system - Error formatting /system!
Format data- Error formatting /data!
Format cache- Error formatting /cache!
I was afraid to format emmc or boot.
Does this help anyone?

Have you tried creating a bootable CWM SD card? That always helps me out when things get screwy.
Tried the EMMC recovery repair?
p.s. - NEVER format Boot. You'll have many a difficulty if you do.

I do have a CWM SD card and can boot to that as well.
Neither one works. I tried installing
nookcolor_1_4_1_update.zip
update-nc-stock-1.3.zip
encore_CM72-MiRaGe-03232012.zip
All leave me where I am now

How old is the nook?
What happened when your friend tried to install cm7? What was going on with it prior to installation?

Don't really have much info.
I have no idea how old the NC is.
I believe that the guy had stock B&N running and tried to install CM7 (verson unknown) with a bootable microSD card, I don't know if he was using the latest CWM on the card.

Um........mail it to me. I'll fix it.
Minimum fees apply.

Here's another clue.
I have a dual boot SD card made based on the instructions in
[ROMS]NEW! Dualboot Mirage CM7 / ICS CM9 Image for SDcard [3/26].
If I use it on a stock B&N NC, the SD card works correctly.
If I use it in the borked NC, it still boots into a black screen.
I would prefer to try to resolve this mayself. I have 20+ years in PC support and feel if I can just get the right information, I can fix it.
If I can't get it done in the next 3 or 4 days, I may take you up on it. However, the frind would have to OK it and I don't know how he feels about sending it off. Thanks
BTW, I tried plugging in the USB cable to see if maybe I could try some ADB magic, but the laptop slings an error when trying to load the driver.

Let me amend that last post. I tried the dual boot (this time using the alternate boot image) and successfully got into CM9. Does this help me?

I am trying to find a way to fdisk or mount a way to change pemissions to rw,mode=0755 or but cannot find the usb yet. I will see what I can google.
Seems the emmc permissions are wrong possibly.
Edit: this is what my mount says about the nook when I mount it to linux:
/dev/sdb on /media/0838-AA8D type vfat (rw,nosuid,nodev,uid=1000,gid=1000,shortname=mixed,dmask=0077,utf8=1,showexec,flush,uhelper=udisks)

Since I have thee NC booting to CM9 off the SD card, I thought I would load ADB and see if there was something I could do..
I went to [Ref] Nook Color Links |Guides|How To|Utilities| Etc. 12/26 Read FIRST =) in the developer's section and went to the referenced
•Nook Color USB Drivers and ADB Setup (WinXP&7)
The links in that thread are dead. Can someone point out a link to the current prefered method?

have you tried
[UPDATE ZIP] Stock 1.2 update.zip flashable from CWM
from showthread.php?t=1050520

This is nookcolor easy adb 3:
http://db.tt/b3XfztAY
And the USB files file NC:
nookcolor usb
http://db.tt/QRhksG2n

Hi there,
If you are able to boot to CM9 off the sDcard. Try opening up terminal emulator and enter the following commands:
Code:
$ su
# fdisk -l /dev/block/mmcblk0
and paste the output here. That should give you you're EMMC partition layout.
-Racks

Yeah, what racks said. Sounds like you formatted your emmc boot partition to me. In one of the old resurrected threads that you posted to, the OP flat out says they formatted boot.
Don't format boot, everyone.
Post the output of racks command, and we'll know for sure.
If you just formatted (read: erased) the boot partition, then your ROM partition should be intact. That means 8 failed reboot can load the stock firmware. It may be a last-ditch effort for many, but it doesn't require any adb knowledge our even a computer, so I tend to recommend it early.
Reboot as it is loading the cyanogen screen eight times while holding down power,n, and the volume keys. If it doesn't work the first time, do the entire sequence again. Of course, if you enter rack's command, you will see if your ROM partition is still intact which is required for this method to work.

Yep, your missing the last 4 partitions which are /system, /data, /cache, /media. Which you would need to flash any rom. You're gonna have to re-create them by using fdisk from and SDcard ROM (eg. CM7 or CM9). There's a thread here somewhere that dealt with all that. I'll browse through and see if I can find it for you.

This it?

Not sure how to rebuild the missing partitions yet. Appreciate the help fellas.

Touch-Formatter Problem

I tried to reset my nook back to stock, using Touch-Formatter but when I plug the SDcard I see this error message:

E: Can't mount /cache/recovery/log

Could you please help me to solve this problem?

it's possible to find the backup image in the internet?

Carefully re-partition your Nook and see if there is anything salvageable.
There are update and recovery packages all over the 'net.
The problem is to get your personalized Ids and keys back.

try as Renate told but the main problem is every nook have it's uniq info (ID , Serial , Mac Address , Model...etc) so
i suggest u use any program recovery ro recover ur recovery IMage or go to a specialist and ask him to recover ur deleted data .... it can be recovered ..... or there's another solution , if u have friend own NST glowwhite , take a back up from him and burn in ur nook partition ... ur id and mac address will be like him . but i dont know if it will make wifi work or not .... but i suggest turn off ur wifi to avoid get error and just use ur nook for reading
good luck

Would the zip file Nook Simple Touch Full_Factory_Restore.zip work for me in this scenario? If so, where can I get the file?

The backup image should be close to 1.86 GB, so your's could be good.
If in Windows, now you should:
1) create an sdcard to boot the nook from with noogie in it. Search the forum for noogie.img.gz and you should find instructions
2) insert the card in the nook, restart the nook, and hook it to your computer
3) in your pc run win32diskimager or diskimage and write your backup to the pyhisical disk that's 1.8g GB in size.
4) make sure nothing goes wrong, and if successful eject the sdcard and boot the nook normally.
good luck

I restored the backup and bootted with noogie, the partition info using partition wizard is:
Partition: Disk 2
Capacity: 1.82 GB
Used: 0 B
Unused: 1.82 GB
File system: Unallocated
Status: None
So, I think the backup is not good.
With Partition recovery I recoveried the old partitions of my nook, and I boot with noogie, the partition info using partition wizard is:

if you run
Code:
fdisk -l /dev/block/mmcblk0
from within ADB you should see something like this:

128 heads, 32 sectors/track, 934 cylinders

/dev/block/mmcblk0p7 406 525 245744 83 Linux
/dev/block/mmcblk0p8 526 926 821232 83 Linux
And you should be able to mount every partition without errors or warnings:
Code:
mount -t vfat /dev/block/mmcblk0p1 /boot
mount -t vfat /dev/block/mmcblk0p2 /rom
mount -t ext2 /dev/block/mmcblk0p3 /factory
mount -t ext2 /dev/block/mmcblk0p5 /system
mount -t vfat /dev/block/mmcblk0p6 /emmc
mount -t ext3 /dev/block/mmcblk0p7 /cache
mount -t ext3 /dev/block/mmcblk0p8 /data
if this is not you case, then it will take some time and expertise to revive your device.
You'd better go step by step and avoid mistakes (been there, done that) =)
