[Q] Bricked, Borked, Boat Anchor? NT Help! - Barnes & Noble Nook Tablet

Hopefully someone here can help! I have never bricked any of my devices. But this one has me totally wiped out. Apparently I have corrupted the partitions somehow. I have tried every method on here and nothing seems to work. I did this once before but was able to adb into parted and fix. Now I can occasionally get the command prompt to start but very seldom. If I could access the command prompts then possibly someone could get me through this problem. I thought Adam's method was going to work after letting it run all night. It got by the mlo writing and hung at the system. Oh well! Says no fat 32 is one error when trying to run the parted fix.
Here is the other error.
E:format_volume: make_extf4fs failed on /dev/block/platform/mmci-omap-hs.1/by-name/cache
I generally can read from what everone posts and get things working but this time is a no go. Oh yeah forgot to mention I can boot the latest CM7 off sd card. I just need my EMMC working. Yeppers that's what I need. Otherwise I'm just going to use it as a frisbie or oversized hockey puck.
Thanks!

I had a customer brick his trying to partition it as well. (I'm the sales manager at Barnes and Noble) I flashed the 1.4.0 acclaim update on an sd card and it restored it. Not sure if he was using the same method as you but it's worth a shot.

If this happened while you were trying to repartition, I would suggest using AdamOutlers ubuntu recovery oprion from the development page. This will reset all of your partitions to original settings.

@jmeyerhead - I tried the acclaim_update. Didn't work. Was hoping I could make it work from SD Card. Apparently that's not possible. Unless someone can tell me how with cm7 running from card. Thanks J....
@know_fear - I wasn't trying to partition. I think what happened was when I went to storage I went down the list and hit unmount from the list in all the locations. Why? Don't know! Just seeing what would happen. Well I found out what happened. Boat anchor. I did try adamOutlers ubuntu recovery several times. It made it through mlo wiping finally but hung at system. Let it run for about 12 hours. Made the card using windows. Would making the card in Ubuntu possibly make a difference? You can tell I'm not a pro at this but I manage to read and get around a little. I did try the parted script. But says no fat 32 if I remember right. Now I can't even get daemon to start running so I can throw in some commands. Oh well! Still open to more suggestions. Thanks again guys!
Thanks know-fear

In all honesty it seems like the parted script should work. If you have a spare sdcard, I would try to put the parted script on that. Boot into the recovery from your original sdcard. Once there, remove that card and insert the one with the parted script on it and try to rerun it. Not sure what else to try. Perhaps you can PM CelticWebs and he may have more insight. Otherwise drop by the IRC channel on freenode (nook-tablet). Indirect and Frustro (servergod) might be able to help more than I.

Yes parted will work and will fix your problem no need to do use a factory restore method. That error means that your cache partition does not have name I don't know how for the life of you got to remove it's name but by just giving it's name "cache" back should fix it.
Post a print of parted here to check the partitions and I'll tell you what to do.

@Veronica and @know-fear--I can't even connect to use commands. Not sure why it won't work. Sometimes it does and then it doesn't. I'm not very proficient in terminal with adb commands so I would need a bit of help there My evo connects just fine when plugged in so it's reading phone drivers. When I plug in the NT under Disk drives it shows B&N NOOK Tablet USB Device twice also shows up as Generic STORAGE DEVICE USB Device. Nothing shows up in Computer like when I plug in my evo it says Android USB Devices and under that My HTC. I used your post Veronica to set it up to see all my devices a long time ago and worked great. But ever since I had this problem nothing is going right. I can't even remember what commands I used to get it to read parted and as for installing or pushing not real sure about that. Everything NT related for adb I put in a folder called NTRoot. So much for the book report haha! Thanks for helping and hopefully helping more.
Nice Day!

Have you tried booting CWM from sdcard and run adb?
Sent from my Nook Tablet using xda premium

Yes it boots from sd card but adb won't start. I have got it showing my device now but won't kick the whole daemon into gear. I get to the c: drive then type cd adb_shell and then type adb shell but nothing happens. It gets to the # but nothing after that. Hit and miss. Sometimes it works and most of the time it doesn't. Would adb work from my phone possibly more so than windows 7 command prompt as administrator?

Well this is what I have showing. Not sure this will help. Thanks

You need Adams total wipe method that should recover your partitions and get you back to stock or if someone has the partition images for 16gb NT even better as is faster.
~ Veronica

Veronica,
I have used Adams total wipe method 3 or 4 times. Sure seems like it's a great program and probably works for lots of people. But just hasn't worked for this messed up tablet. I have let it run for hours. Maybe it just needs to run for several days since this thing is in such bad shape. It does get past writing zero's to mlo but seems to hang at system. So in your opinion should I just let it run and run? I thought it only was supposed to take about 15 minutes. Any ideas on where to locate the partition images for 16gb NT?

Forgot to mention the adb commands would not work in usb 3.0 port. So I plugged in a usb 2.0 hub and worked perfectly. Crazy goings on around here. Must be the solar flares.

Give me sometime to pull the partition images and upload them. You be my tester as adb is working for you so you're good to go. Images will contain stock ROM, oh and you will need Linux. Ubuntu is recommended... burn it into a CD/DVD, or create a virtual machine with it; you will need adb working there too >> for that you need to download sdk from official Web page and set it up. Questions are welcomed.
Edit: I just made a guide that will help you setting up ADB on ubuntu: http://forum.xda-developers.com/showthread.php?t=1550414
Edit2: i got the images but from mmcblk0p1 to mmcblk0p9 as i don't have a higher sdcard to backup images 10 & 11 but with 1-9 you good to go. Size of the zip containing them is 686 MB, pfff that will take a while will leave it uploading over night...
If you dont know what am i talking about lol i explain:
16GB Nook Tablet has 11 partitions each one located under /dev/block folder, named mmcblk0p* (where * is 1-11]). So had to use dd to copy the images of each one to /sdcard.
This table is useful to know the order and name of the partitions (Got it using Parted) and added the >> mmcblk0p* file name that belong to each of them:
Number Start End Size File system Name Flags
1 131kB 262kB 131kB xloader >> mmcblk0p1
2 262kB 524kB 262kB bootloader >> mmcblk0p2
3 524kB 16.3MB 15.7MB recovery >> mmcblk0p3
4 16.8MB 33.6MB 16.8MB boot >> mmcblk0p4
5 33.6MB 83.9MB 50.3MB fat32 rom >> mmcblk0p5
6 83.9MB 134MB 50.3MB fat32 bootdata >> mmcblk0p6
7 134MB 522MB 388MB ext4 factory >> mmcblk0p7
8 522MB 1164MB 642MB ext4 system >> mmcblk0p8
9 1164MB 1611MB 447MB ext4 cache >> mmcblk0p9

Hi Veronica,
Just got in and noticed your post. Totally cool! Not that familiar with Ubunto. Have used it a tad. Straight on!! The thing I have a problem with in Ubunto is that I can't access my folders in windows. So constantly have to reboot back into windows 7. Or maybe there is a way to access, but just haven't figured it out yet from the times I have used the program. I'm probably going to just go out tomorrow and get a laptop . Just don't know what I want. Really wanting a transformer prime. I'll have to toss the coin. That way I can jump back and forth without rebooting. Anyway's thanks for taking interest in my dilemma and trying to point me in the right direction.
Nice night/day
Chris

No need to install it directly just download virtual box or VMware player and create a virtual machine with latest Ubuntu 11.10 image . Its always good to have ubuntu.
Once installed ubuntu follow my guide to setup adb.

[Q] Internal memory become read-only

Sorry for my English.
I have NT 16G with CM7. After waking device from sleep, I was unable to toggle wi-fi state, it stuck on "Turning off.." message. When I tried to restart tablet, it shutdown but not boot up. Just stuck with blank screen and backlight on. So I held power button to shut it off. Then turn it on again.
After that, I can't change anything in internal memory. Device turns on and works for some time, but then restarts on it's own and go back to state before wi-fi problem. Any changes, as new/removed files, applications etc, revert back. Even full wipe via Ubuntu didn't work: after reboot everything back to previous state.
In dmesg I have message
Code:
mmcblk0: retrying using single block read
Any suggestions?
Can you boot into cwm? Try fixing permissions and try again.

It didn't change anything. Looks like I have hardware damage. Is it possible?
Its a kernel regression, you need to format that mmcblk0 and re-create.
If this doesn't work sent for replacement as it may be a faulty chip.
How can I format it? It doesn't accept any changes. Is there any other way?
Reformatting the internal partition can be a screwy and hard thing to do. Not because it's hard to format, but simply because it's hard to retrieve the original table. Because the first 4 partitions are very secure, They need to be matching perfectly with Barnes & Noble's partition table. I recommend you just try my guide on unbricking stuff:

So everything looks fine. Have you dumped xloader bootloader recovery and boot partition using lavero.burgos. images??
Sent from my NookTablet using XDA
dd back the partitions, you will find a backup of them if you search the forum
I've tried it already. It didn't change anything.
Any errors?
No.
So remove partitions 1by1 format and re-create.
I cant see anything else to work.
You can use a custom recovery with excellent tools for you made by meghd00.
I recommend to use that.
After this report back.
I've tried meghd00t method already. No results.

[Q] Missing mmcblk0p5 and can't download mmcblk0p8

Hi, Experts.
I am new to rooting and I think I screwed up my NB 16GB. I used ubuntu to connect into my NB and there is only /rom but no devconf folder. My serial number is now 0000000000000000. I am going through the steps of http://forum.xda-developers.com/showthread.php?t=1570022 but I can't download mmcblk0p8 and there is no mmcblk0p5. How can I get these 2 files? How do I know which mmc I need to restore? I can't even boot into CMW.
I can only boot to CM7 via sdcard. Is there any thread to guide me on how to recover via CM7 instead of ubuntu? Thanks.
Change to linear or full view and then you can download, i just checked and that works. I don't know why in grid view it wouldn't download but i guess is a bug in minus.com.
About mmcblk0p5 i moved it to another private folder and i will be giving the link only if needed that way i have more control of it. If you still need it the pm me and i'll give you the link.
Edit: I modified the folder's view to linear so now you can download.

Now it says file does not exist
Hi, Veron.
Thanks for your reply. I tried but now it says file does not exist. I have problem previously with other files and I tried on IE, FF and Chrome. Only IE allows me to download but mmcblk0p8 is the only 1 I can't download with all browser.

I still can't download mmcblk0p8. Is there a way for me to test which partition is corrupted and if I need mmcblk0p8? Maybe I just need to do some and not all.

I am a novice in Android. I went into storage card, erase some of the partition. Now I can only boot into CM7. I can't boot into CWM. If I took out the CM7 sdcard, it will not start nor will not show the N logo. Taking out the card also no effect. It is just showing black screen. Even with usb plug/unplug also will not boot to CWM. Is there anyway to restore the partition from CM7 terminal emulator? Any commands? Using CM7 to restore seems like my last resort
I am from Singapore and I can't possibly do a return in USA.
Please post the parted outcome of print command to see what you have done to your mmcblk0.

Can you explain better that, what OS were you running when you erased the partitions?
For now you have to start burning a cwm image from here to your scard. Why that version? because it was compiles with some useful tools in it that will help you unbrick your device.
Note: would be better if you have 2 sdcards.
Once you have cwm running from sdcard please go to this post, run parted, post the output of print and ignore the rest.
To be explicit i just need this output:

Hmmm oh well i don't know how you did this but your partitions does not have file system e.g fat32, ext4 format.
I assume you get 00000000000000 because rom partition got wiped as well and so your device has no serial ID to show up.
You'll have to use this method and after you fix it (hopefully that works right away) use this to have a serial ID again, i'll have to give you the link of my rom partition (mmcblk0p5) by pm as i keep it private and im giving the link only to the ones that need it by pm request. Let me know if you have any problem, post it and i'll see what i can do.

I'm also new to rooting and I'm experiencing a similar issue with my NT. I derped up when using the instructions here to fix my nook's partition tables. Long story short, I thought I had backed up my mmcblk0p5 and well apparently it didn't save. When I reconnected my nook via adb my serial was all 0'ed out.
Any help? I think the only way to fix this massive derp is a copy of someone else's mmcblk0p5. If there are any other suggestions, I'm up for trying it...

[Q] Delete an unknown partition?

Hi,
I'm a new Android user and this is the first time I "have played" with my Nook Tablet. But I think I've been wrong somewhere. Would you please help me ? Thank you very much!
This is what I've done with my NOOK Tablet:
- My NOOK Tablet is the 16gb version running CM10 SGT7 version 12/9 which has been repartioned by using lavero.burgos' old method in this thread: http://forum.xda-developers.com/showthread.php?t=1531120. I've just played around with partition 10 and 11.
- I tried to return to stock with the method in this thread: http://forum.xda-developers.com/showthread.php?t=1663836
Everything had been just fine until I got the error: "please restart your device and try again if you encounter the same issue, please contact customer service..." So I thought that I had removed my serial number.
- Then I've come back to CM10 SGT7 version 12/9 and there was no problem. But when I look at the "File Manager", I saw in the folder "Storage" there were 3 sub folders: SdCard0 (which corresponds to my "SD card"), SdCard1 (which corresponds to my "Internal Storage") and the "usbdisk0" which had not appeared before. I believe that the 3rd folder (partition ?) was created by returning to the stock.
- So, I've tried to repartition the internal storage again (twice, both the old and new methods) but the folder "usbdisk0" still exists.
This is the result:
Model: MMC 016G4A (sd/mmc)
Disk /dev/block/mmcblk0: 15.9GB
Sector size (logical/physical): 512B/512B
Partition Table: gpt

8 522MB 1164MB 642MB ext4 system
9 1164MB 1611MB 447MB ext4 cache
10 1611MB 11.6GB 9989MB fat32 media msftres
11 11.6GB 15.9GB 4338MB ext4 userdata
When I check the storage, it says that I have 3.98gb for internal storage and 9.29gb for the remaining. There is approximately 1.5gb lost (maybe it's the size of "usbdisk0")
I cannot store any file or create any folder in this "usbdisk0"
How can I delete the "usbdisk0". That would be very nice if you can help. Thank you very much.
Sorry for my bad English.
USBdisk is normal. It is for USB otg. Which is still not working on NT.
Your problem is elsewhere

Nook Tablet partishions missed.

I have bricked Nook Tablet BNTV250A (8gb) that I can't flash on any Rom. My partishions are completly missied so I can't even Restore from Factory.
But I still can boot from SD.
When I look my partishon I see this
~ # cat proc/partitions
major minor #blocks name
179 0 7766016 mmcblk0
179 1 7764992 mmcblk0p1

179 96 15632384 mmcblk1
179 97 50176 mmcblk1p1

Can somebody help me and can I boot this tablet into Rom anyway? As I undestend my factory info (as MAC address) is dead but if you have any ideas I be happy.
Thank you.

Thanks so mutch! I after first step flash stock recovery and it works!

a Dummies Guide to repartitioning ?

let me first say that virtually none of what follows is my own work!
I have simply 'tweaked' and plagiarized the brilliant postings made by others, to hopefully make it all a bit more idiot proof for newbies, and lesser mortals such as myself. (respect to 'tselling' in particular) ...
Note that this only for 16GB Nooks that have been rooted, and with CM Recovery available
I'm sure it would work on the 8 gigs, but don't know the figures to use
background:
after rooting, installing CWmod, and a CM 10 rom on my 16 gig Nook Tablet by following the great guides on here, I then wanted to go the whole hog and repartition it.
initially, Veronicas post here: http://forum.xda-developers.com/showthread.php?t=1531120
seemed the best, as I could get 12 Gig for myself. sadly it did not work for me as my copy of Cwmod does not support 'sqdisk' - but I learned a lot nonetheless.
I then found 'tselling's great post here:http://forum.xda-developers.com/showpost.php?p=22157605&postcount=25
I eventually resized my partitions to approx 4GB & 9GB, but not without some issues.
the posting stated that all actual commands were in bold, eg: 2nd command was (parted) print but this failed.
“back in the day”, I was very good with MSDOS and batch files, so I knew in my heart that I had missed something obvious!, yep! - (parted) is the screen response, print is the command ... from then on it was all a bit of a doddle
so here is my two pennyworth:
preparation: read everything at least once! ... and ensure you have done a full CM backup !
1. from all the great guides on here, ensure that you know how to connect your Nook to a PC,install drivers, and 'ADB' etc, and how to get into an ADB Shell.
2. the method works via CW Recovery, which can be either from an sdcard, or installed internally, (as mine is). do not continue until you are comfortable with all that
3. reboot your Nook into Recovery, cable it to your PC, and get ADB running.
4. run command ADB devices, then ADB shell to ensure you have connectivity.
5. all the actual commands to enter into your PC are in red (some are just single letters)
6. screen responses from ADB are in black (but not bold)
7. my comments and observations are in blue (but not bold)
8. despite the length of this post, (and my blathering), the whole process takes less than 10 minuets, and only entails the copying and pasting of 24 commands from here, onto your PC
9.some of the screen responses you will get are not exactly as I have got shown below. (this is simply because I had already done it once for 4 & 9 gig, and this was my 2nd run for 12gig.)
10.even if you mess up, don't panic, as the backup you made earlier can easily be restored with your CM recovery, and you are good to go again.
11. so let's start:- below are the commands to copy into your PC (remember, red lines only)

~ # reboot recovery (finally, the last command)
at this point the Windows CMD box on your PC will drop out of ADB, and your Nook will reboot back into Recovery,
where, from “backup and restore - advanced restore” you can restore your data partition only.
Reboot system yet again, and all should be fine
I have attached photo of mine.
...........................................................................................................
Also, once you've done all this you can, if you wish, go back into an ADB shell and enter the following commands one at a time
cd "/data/media/B&N Downloads"
rm -r *
cd ..
rmdir "B&N Downloads"
ln -s "/media/B&N Downloads" "B&N Downloads"
this points your B & N library to your /media folder for downloading, helpful if you want to manage all your books in Calibre.
...............................................................................................................
again,
many thanks, and my full respect and appreciation, to all those whose knowledge and postings here at XDA have made all this possible for the less experienced amongst us.
Kevin
ps: it's a pity though that I do not know ADB as well as I do MSDOS, else I would have compiled a 'batch file' or script to make it automated.
Wow. Thanks. This was just what I needed. For some reason, I simply couldn't get my PCs at home to load the appropriate USB driver update for my Nook. So I did it on my Mac. I have RARELY ever opened a shell on a mac. But with a couple searches, a download or two, and this simple guide, not only did I get my nook to show up on my mac (via CWM) but to also adjust my partitions.
Awe-Some!

But with a couple searches, a download or two, and this simple guide, not only did I get my nook to show up on my mac (via CWM) but to also adjust my partitions.
Awe-Some!

Nook was recognized as NookTablet without driver from recovery, instead of ADB device or something, so I couldn't update driver for it, as it didn't
Took me 40 minutes to finally give up and open my work mac. Worked like magic from there.
Can anyone explain why this happens on windows?

Did the whole guide (thanks a big for really easy-to-follow guide), because I thought that it's totally locked and unusable with Cyanogenmod. And then I understood that it's actually used by CM for apps, apps data and cache.
So I have few questions.
1. After some time of usage, do you feel that 2GB is enough for all apps and their data?
2. Is it possible to make apps that do additional download use internal storage (the freed 12GB) instead of requiring external SD? Is it maybe a matter of mounting it as sdcard1 somehow?
3. Is it totally impossible to use same partition both for apps and for media and just mount some folders right way?
Sorry for the noob questions, i'm just totally new to android partitioning and mounting.

I'm glad that you managed it ok with you Mac and the only thing I can think of re Windows USB drivers is that sometimes windows can have too many drivers on it ( from other devices that you may not use anymore) and it gets confused
this has happened to me, and I use a simple utility I found called USBDeview with which it is easy to uninstall drivers for old phones/printers etc.
it can be found here: http://www.nirsoft.net/utils/usb_devices_view.html
as to your other 3 questions, 2 gig for apps has proved more than enough for me,
but I don't know enough to advise on you with Qs 2 & 3.
fstab
Hi, something that I missed in your guide.
You said you modified "fstab".
Can you tell what is it and why/how to modify it, or point to good article about it?

I'm sorry mate. but I can't remember!
I picked up everything from either Veronica's or Tselling's original posts as I said,
and can only assume that this was something I actually did whilst doing the process.
I don't have the Nook anymore, so cannot go through it again as I did. having said that it probably isn't that important

Fstab is a file that checks where your drive partitions are mounted. For example, on Linux, it's stored as a file called /etc/fstab, and you modify it if you want to map other harddrives or partitions (or even ISO images and such) to a mountpoint.
It is VERY important. If you mess up your fstab, your computer or device may be unable to boot, depending on how much you mess it up (but your data will remain intact).
