[Q] HELP! possible bad sd reader restore to stock - Barnes & Noble Nook Tablet

Just got a factory refurbished Nook Tablet 16GB from B&N and rooted it and installed CYM 7 and it seemed to be working. After doing so, I started having issues with the SD card readers. I originally had a 16GB class 6 Sandisk card in it, but also tried a class 4 4GB Sandisk and a class 10 Microcenter one and all have problems reading. What I'm trying to do now is restore it to stock and see if I can get some help from B&N. Right now, it will give me the N screen and then will show Cyanoboot(it won't let me hold down N to get any menu) and say loading recovery from EMMC and then it will only go into TWRP. I try to install various images from the different SD cards but all will fail. Error messages in the log show E:failed to mount /emmc and E:unable to mount messages. Any ideas on what else I can try?
Thanks,
Col

IJust in case it's not a hardware fault:
Try making a bootable CWM card, boot into it at start over again.
Or you could try the "repart.img" unbrick card.
Searches should bring you to either.

Tried the repart.img to a card. It appears like it works and then says it's going to reboot and never does. Rebooting then brings back the cyanoboot screen and TWRP.
I can boot from a CWM card, but I'm not sure what to select. When I try to factory reset, I get errors:

OK, if you can boot into a CWM card, do that and put something flashable at the same card so it's there when you boot into it.
I'm guessing your bootable CWM card is 5.x.x so you cannot flash CM10 with it. Try putting a CM7 on the card before booting into CWM. That way you have a working system.
TWRP did not play well with my NT and my SD card. CWM has never failed me though!

I guess I'm suggesting something along this post (even though I haven't followed that particular routine myself)
http://forum.xda-developers.com/showthread.php?t=2037368
FWIW, I did something like what's in post 25 of that topic to install my CM10.

OMG! My memoery is really bad! I totally forgot that I had trouble getting into cyanoboot when doing that! I see now my own post in that topic, just a few days ago... I used a CM10 sd-card just to get inti cyanoboot, and then I went on from there.
And by the way, what happens when you run the repart.img? What should happen is first it says "don't turn off you device" (or words to that effect),a dn after a not too long while a green checkmark appear. At that point, remove the card and it probably reboots itself, and goes into a new (smaller) "don't turn off..." and that part takes wuite a while.

I just load everything on EMMC and have a copy of the NT recovery flasher apk on hand in case I need to revert to stock.

Well, I tried to boot to a CM7 boot image on the SDcard and it starts to boot and gives me the CM7 screen, but then kicks back to the Nook N screen and boots back into TWRP.
I tried to the repart.img again and it boots, gives me the Please do not turn off, etc. screen, but with a red X in the corner. It then gives me the message that it's done and will reboot, but never turns back on. If I boot it again, it goes back into the TWRP boot.
Stupid question...is the EMMC the SD card or the internal memory? It seems like the errors I get are related to the emmc.
thanks for all the help.

More updates...I got it to boot from a CWM-based recovery SDcard v.5.5.0.4 and when I try to flash a zip file from the SD card, I get the errors:
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
Error mounting /emmc!

Ok, what's in this post makes my head spin, but it seems like it could fix the problem...

Trying to get adb running and seeing the device, but no dice right now. Windows seems to recognize it and see storage, but ADB doesn't see it. Am going to keep fighting with that to see if I can do anything through there.

Check android_winusb.inf (Program Files -> Android -> Extra -> USB Driver) to see if you have an entry for the NT.

FInally got adb running on a different PC booting off a USB Ubuntu installation and followed the instructions in the post that Asawi recommended. After that, I used the repart.img file and restored it and it came back up. Now I have to figure out how to tell if the SD card reader is bad.
Thanks for all your help!

CWM crashing, phone freezing. SD wont mount. Can anyone figure this out?

I've looked all over the internet for a solution but they are either only part of my problem or do something that I don't understand with the SDK kit.
So I started up my rooted Droid incredible phone today and it just freezes at the HTC incredible flash screen. I have to pull out the battery to restart it. I can get into CWM recovery but it says
E:can't mount /cache/recover/command
E:can't open /cache/recovery/log
E:can't mount /cache/recover/log
E:can't mount /cache/recover/last_log
E:can't open /cache/recover/last_log
It wont even read anything from the SD card. So I am unable to mount the SD card or access it by usb through the phone.
I tried a factory reset and nothing happened. CWM wont even run a recovery or factory reset.
I am at a total lose.
Please help me fix this!
the SD card wont mount so i cant get to anyone on the card.
It looks like your eMMc chip went bad. Your phone is most likely bricked. The only way to come back from this that doesnt always work is to put an RUU on your SD card and boot into HBoot. I don't have your phone, but the RUU's should be available in your phones forum.

cant mount sdcard

cannot post in the correct thread in developers as i am a noob member but following the noob thread when i get to the step to mount the sdcard in recovery i cannot. i keep getting the error
E:can't mount /dev/block/mmcblk1p1 (or /dev/block/mmcblk1)
(no such file or directory)
what exactly are you trying to do? a little more info would be nice. you said you are trying to mount in recovery? for what reason?
Aren't the SD Cards auto mounted in Amon-Ra recovery? Wouldn't that error be due to the fact that they're already mounted?
Use Amon-Ra or Clockworkmod; While in recovery mount SD card.
I had to restore my laptop back to original factory settings for it to recognize my phone.
had nothing to do with the rezound, my computer woulndt install any new drivers..
if I had usb debugging turned on the computer wouldnt find the sd card or internal storage, as soon as I clicked usb debugging off, bang found sd card. I suggest trying this.

[Q] [16GB] Nook tablet bricked, tried almost everything

Hi all, this is my first time posting here, but I have been looking around for the past week at guides and How-to's.
Anyway to my point, my Nook Tablet is bricked and I can't find anyway to bring it back. As of right now, If I remove the SD card so It doesn't boot to CWM, or CM7 it just goes to the grey "N" logo screen with the "Adobe reader" text at the bottom, then immediately shuts off. If I plug in the USB it just goes to the same screen and keeps rebooting over and over. I fear I may of formatted something without really thinking about what I was doing (yes that was stupid of me) and to top that off, in my haste to root I forgot to make a backup (I know really stupid) I've tried many of the different guides and I can't figure out what to do now. So far these are the things I've done or have with my Nook Tablet [16GB]
-I have a CWM SD card
-I can boot from SD to CM7
-I've used ADB and used parted which showed my table, but no fix option. (I compared the table, it matched another user's table that was "fine"
-In ADB I managed to follow Lavero.burgos' guide and redo my partitions.
-I've tried various recovery roms, and I've also tried Adam's Ubuntu Recovery, but I get stuck at "writing zeroes to MLO"
-I also have the "E:\ can't mount" error's in CWM
-I've tried Ray Waldo's method in his video that involves the green check mark, but the NT will show a red X and will power off, powering it back on just leads to the grey "N" logo boot.
-Also my device ID in ADB shows up as a string of zero's "000000000000000" I guess that's the cherry on top of this sundae. (Is the serial number the same as the one on the box and SD flap? If so I guess I still have the number)
I've tried more things, I'm sure they'll come back to me the more I think about it. So what it seems is that I can't boot from internal anymore, that's just my guess. sorry for having this wall of text, I'm just trying to provide as much info as possible. I would just return it assuming that they wouldn't find rooted files or anything of the like since it won't even boot properly, but this Nook was brought into my store and traded in second hand. (Still have the box though)
Thanks for your time!
Hey, just some quick info. I bricked my nook the first week I got it. I users the sd restore method with the green check mark. It seemingly worked however when it booted it would go the screen with the yellow arrow. After getting frustrated from numerous boot loops, I left it plugged in overnight and the next day it was working fine. Anyways that method MAY be doing the same for you? Good luck and don't get too frustrated!

Do you mean just leave it plugged into the wall charger or computer? Also do you mean you just left in plugged in so it would continuously go to the grey N logo screen?
Thanks for the reply by the way!
*edit*
On my original post, I clarified that Ray Waldo's green check mark method didn't produce a green check, just a red X
I left it plugged in charging overnight to the wall. But, I also got the green check mark before having done that. It would boot to the n screen then go to the yellow arrow screen immediately after. I don't have any other suggestions for you, sorry. I consider myself a noob when it comes to the nook. It seems like more of a pain in the ass than most other Android devices.

**this first set of errors usually occurs when you accidentally format the usrdata partition which in stock partitions is the 1gb of user space on the 16gb nook. i had that happen and just followed the following thread to get it fixed: http://forum.xda-developers.com/showthread.php?t=1513583 **

this second set of mounting errors looks like your partitions are screwed up. but you say you fixed your partitions using lavero burgo's thread? is there any way you can confirm that your partitions are formatted the right way?

the serial number with all zeroes is normal. its just adb not getting the correct information from the nook tablet. if you go into the rom folder and locate something that deals with a serial number and open it to view it, you will see that it isn't all zeroes...
not sure why adb gets serial information as all zeroes but w/e... as long as adb works thats all that matters.

Well I guess all I can really confirm was when I fixed the partitions, and ran a parted command, my Partition Table came up, and It had no mention of errors or told me to "type Y to fix corrupted partitions". I cross checked the partition sizes and they looked very similar to this:
Code:
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 16.8MB 33.6MB 16.8MB boot
5 33.6MB 83.9MB 50.3MB fat32 rom
6 83.9MB 134MB 50.3MB fat32 bootdata
7 134MB 522MB 388MB ext4 factory
8 522MB 1164MB 642MB ext4 system
9 1164MB 1611MB 447MB ext4 cache
10 1611MB 2684MB 1074MB fat32 media
11 2684MB 15.9GB 12.9GB ext4 userdata
Which is, from what I've read, correct or what it should look like.
Perhaps I overlooked something within the repartition process, but from what it seems if I did do the repartition correct, I'd be good to go and get my nook back to working order? If so then obviously I must of missed something which I suppose can narrow it down considerably.
Thanks for your time by the way, it means a lot to actually talk to someone about the issue after being a bit frustrated.

Ok I want to say I'm really close to fixing this now, I'm currently in ubuntu, since that was the only way I could ADB, I have the repartition files, I'm pretty sure I have it all mounted properly, and I can see my device ID come up, when i type in
Code:
parted /dev/block/mmcblk0 print
Then it tells me
Code:
WARNING: You are not superuser. Watch out for permissions.
Error: Could not stat device /dev/block/mmcblk0 - No Such file or directory
Which immediately leads me to believe I must be missing something important, or perhaps I haven't mounted everything correctly? Should my nook tablet be in CWM if that really matters?
*Edit*
To clarify to my previous post about my Partition Table, when I run the parted command, the file size match up, and it doesn't give an error saying its corrupt, but under the File system column, there is none, its just blank if that matters.

My device shows up in ADB with my serial number, however it gets stuck on "first need to make sure you didn't lie about it showing up, I also need to check for root incase you want to run any updates!" I was using Nook&Zergy for ADB.
Hopefull the fact that my serial number still shows up in ADB is a good thing? Any help?
Well, I figure I'd just go for broke with this, and I started this guide for Completely Dead Nook's and fixing the Partition Table. Everything worked great up to the part where you recreate your partition, when I input that command, I get a "Permission Denied" error. I went back to the start but this time enabled "su" and I still get a Permission Denied.
Essentially I think I could get this working, except I'm just stonewalled at this one part. (Although I guess I could dig in for the long haul and manually recreate using the parted way...right?)
*edit*
OK I finally believe I've made some headway. While I got the "Permission Denied" error, I figured I could just go a manually recreate all my partitions, which I went and did going off the guide. Now when I boot back into CWM I no longer have the string of E:Mount Errors !
I'll report back on progress, I assume I'm heading in the right direction if the errors are gone no?
*Update*
Well the errors are gone in CWM, but I still am stuck with a bootloop/constant restarting at the grey/silver "n" logo. I tried Ray Waldo's unbrick, which has the whole green check mark stuff, but I still get a red x. Perhaps I missed something, any clues?
Another update, Adam's Ubuntu Recovery is no longer stuck at "writing zeroes to MLO". This seems to be a very good sign
Another update, It's working! I used Ray Waldo's unbrick method, got the green check, but now I get an error when it registers the device, which I know is tied to partition 5 which i recreated, I thought I had made a proper backup, but I guess I made a backup of when it was already formatted, so is it possible to get my Serial Number, MAC address what-have-you back, if not what are the options I have?

well since you redid your partitions, most likely the rom partition is missing files. that partition has all that info: serial number mac address,etc...
you can get the serial number easily if you registered your nook with b&n. just go to their website and log in to your b&n account and under my nook you should see it.
if you didn't register your nook, then that might be a bit more difficult. there is a thread in the dev section i think on getting back your original serial number.
also you can bypass registration if you want to get your nook back in working order with a custom rom and the like. just do a quick search on youtube and there will be video about it by albertcwertz

Alright, I can confirm I have the serial, I just don't know how to put it back into the device, so the registration page picks it up. Any advice?

sorry i am drawing a blank there. i restored my nook tablet using adam's total wipe and i had the problem your having now. not being able to register. i decided to just screw it since i won't use b&n software anyways. i bypassed regsitration and rooted again and then installed custom rom and all is fine lol.
even now when i use adb to get serial info it comes up as all zeroes, but when i go into my rom partition and open the serial number file, my serial number is in there. so i don't really know why registration doesn't pick up the serial number.
maybe b&n has a specific location for the registration process to find out where to look for the serial number info.
all i know is that the rom partition contains information pertaining to the device itself (serial num, mac address, etc).
hopefully someone else will be able to answer your question in more detail.
Well, I think I can just say case closed for now, I guess I didn't want to use stock B&N (Why else would I be here in the first place) I have found a rom I'm starting to really like. Thanks for your help though it is greatly appreciated!
Alrigh Nook gurus, I desperately need your help...please note that I'm only a few degrees above a noob:
*
NT 8GB, formerly running CM7 Beta.
*
I've accidently formatted my emmc and it's causing all kinds of mounting issues, mostly when locating or mounting the cache. Whenever I try to install anything (e.g. backup, new ROM, stock recovery, stock repart) the error "can't mount /cache" comes up and prevents me from doing most everything. When I power the unit on the 'n' splash screen appears for about 3 seconds, then the cyanoboot universal loader comes up states "loading emmc recovery" and goes right into TWRP. Although it states "hold 'n' for menu" it will continue to boot TWRP. Therefore I do not have the option of accessing fastboot, and even if I did it would likely result in the usual "can't mount /cache" error that I get when trying to flash anything. Here's what I've tried and a summary of the result:
*
I've tried the "repart.img" stock recovery method. It will load the downward arrow and say "updating", then it states that it will reboot and reminds me to remove my sd card. It does not reboot automatically, and when I manually power on it goes right back into TWRP.
*
I've tried the Ubuntu boot method, but after I downloaded the 1GB file, unzipped it, added .img to the file, flashed to SD, inserted into NT, power on...then goes right back into TWRP.
*
Everything else involving flashing recoveries (cwm, twrp, stock) I've tried, always resulting in cache mount errors and no change boot up. I am able to boot CM7 Alpha Final via SD card, but only when I insert the card and power the NT up via PC-USB connection. Also, I can boot into CWM recovery via SD card when powering via PC-USB connection. When I power up normally (with the power button) its as though the tablet disregards what is in the SD slot and goes right into the emmc recovery. If anybody has any insight as to what might fix this, please let me know.

Although it states "hold 'n' for menu" it will continue to boot TWRP. Therefore I do not have the option of accessing fastboot, and even if I did it would likely result in the usual "can't mount /cache" error that I get when trying to flash anything. Here's what I've tried and a summary of the result:
*
I've tried the "repart.img" stock recovery method. It will load the downward arrow and say "updating", then it states that it will reboot and reminds me to remove my sd card. It does not reboot automatically, and when I manually power on it goes right back into TWRP.
*
I've tried the Ubuntu boot method, but after I downloaded the 1GB file, unzipped it, added .img to the file, flashed to SD, inserted into NT, power on...then goes right back into TWRP.
*
Everything else involving flashing recoveries (cwm, twrp, stock) I've tried, always resulting in cache mount errors and no change boot up. I am able to boot CM7 Alpha Final via SD card, but only when I insert the card and power the NT up via PC-USB connection. Also, I can boot into CWM recovery via SD card when powering via PC-USB connection. When I power up normally (with the power button) its as though the tablet disregards what is in the SD slot and goes right into the emmc recovery. If anybody has any insight as to what might fix this, please let me know.

Your tablet is basically in recovery mode. So you most likely have your partitions screwed up. Look at the thread in the development section about repartitioning your internal memory

Unable to Mount Internal Storage

Hello all,
I have run in to some issues with my phone today, and have spent several hours trying out different things, and reading through the forums.
My phone is unlocked, s-on, and have had no problem loading multiple different ROMs in the past. The most recent ROM I was using was Carbon 1.7. It had been working well for the most part, periodically the phone would restart itself, but I didn't really consider that an issue.
Today though, I was taking a photo with the phone, and it restarted itself. Upon the restart, it became stuck at the HTC boot logo. Once I got home I investigated it some more, and figured I'd try and just wipe the cache/dalvik, and this is where I came to realize I might be in a big mess than originally thought.
I'm not able to wipe the cache, dalvik, system, or anything. I try to flash a ROM, and it seems to work, and since i'm S-On, I try to load the boot image with Hasoon's All in One Kit, but still stuck at the boot logo. I try to do a full wipe from within the ROM when install, and also tried a full wipe with Super Wipe, but no luck.
This is what I'm seeing (I've tried using TWRP, CWM, EXT, and all come up with something similar):
E: Unable to mount '/cache'
E: Unable to mount '/data'
E: Unable to mount '/system'
E: Unable to mount '/devlog'
E: Unable to mount '/emmc'
E: Unable to mount '/emmc'
E: Unable to mount internal storage
I've racked my brain as much as I possibly can. I consider myself a noob when it comes to most of this stuff still, so any help would be greatly appreciated.
Thanks so much
I recently sold my amaze to a coworker and over the weekend if started doing the same thing i spent all night trying to figure it out... I did a full wipe except sd and it wouldn't recognize the sd card. It was running cm10.1

S-Off your amaze. Then apply a stock RUU. I had to downgrade to GB to recover my phone. Android 4.1.x and 4.2.x roms tend to have this bug of partition corruption with our phones.
Fix internal storage error
If you wipe or factory reset it from the bootloader, it may kill the internal storage partition. Just connect USB, go into recovery, unmount and remount USB storage, it will recognize the internal storage and say its unformatted. Then format it as fat32. Then you can do a wipe and reimage. Thanks to OM4 from XDA for posting this. Worked for me!!

Bricked 8gb Tablet. E:/Cant mount SD card

Okay, I don't normally post. In fact I always normally find solutions using the search, but I am out of options and at my wits limit.
I have an 8gb nook tablet which I loaded up with CM7. After I booted it up I reformatted the SD card to start fresh.
Upon restarting the tablet It would no longer boot into CM7 and would instead get stuck on CWM.
"No problem I thought, Ill just re-flash it from my SD card" But when I went to install it from SD card it told me
it couldn't mount the SD card. I rebooted and again landed in recovery which yielded the following 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 already tried the B&N8gb/16gb .img that restores the tablet to stock but that was a no go.
I then tried to make a bootable SD card using the CM7 alpha but that also did not work
After I tried to use the Ubuntu recovery to 1.4.0 but realized that it was only for the 16gb nook
I got what I think is ADB going on windows following this thread
http://forum.xda-developers.com/showthread.php?t=1474956
So I could try this solution
http://forum.xda-developers.com/showthread.php?t=1513583
But I can't for the life of me figure out what I need to type into CMD. It's been 3 days. I have never been so lost and confused in my life.
Pleas kind strangers of XDA. Help me.
