Bricked 8gb Tablet. E:/Cant mount SD card - Barnes & Noble Nook Tablet

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.

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.

[Q] Can I Save My Nook (if possible)

First off I want to say thanks to all the Devs on this site and those who contribute. Secondly I'm pretty computer Savvy and I have no clue what I've done.
So I had Cm7 running on the nook for about 2 months some where along the line my girl did something and it died. I then used albertcwertz repart.img. I then rooted and reflashed Cm7 all is fine. Until the next day the nook just wigged out and wouldnt turn or go into cw recovery.
So I tried the repart.img again but now it says installing software and a red X in upper right had corner then says powering off device in 5 secs and then nothing.
Next I tried the ubuntu sd card and it never got pass the MLO part of the wipe.
So now I'm trying to wipe everything manually through a VM Ubuntu but I cant mount the Sd card and it says
E:Can't mount /cache/recovery/command
E:Can't mount /cache/recovery/log
E:Can't open /cache/recovery/command
E:Can't mount /cache/recovery/last_log
E:Can't open /cache/recovery/command

You may also want to try @succulent's flash-restore-stock.zip (Click on View RAW)
flash-restore-stock.zip (use it to restore partition 1-6)
- Only use this as last measure. Meaning only if you formatted rom (p5) and bootdata (p6).
- You will need to install flash_stock_1.4.2.zip afterward or a CM7 rom.
- To get your serial number back, you need to perform factory restore (8 failed boot method)

A reset is being performed.

[Q] HELP! possible bad sd reader restore to stock

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:

E:format_volume: make_extf4fs failed on /dev/block/platform/mmci-omap-hs.1/by-name/userdata

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...

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!

How to ADB recovery

Hi,
I have a nook tablet, and while after I installed cm7 team-b rom, everything
worked fine until the device restart itself and didn't work again
I found this topic http://forum.xda-developers.com/showthread.php?t=1513583
that has the solution to my problem, but I couldn't do it because of ADB
any help?

If you're having problem getting ADB setup to work, this method is probably not a good first-choice solution for you. I'd suggest flashing back to stock first using flash_stock_1.4.2.zip at https://github.com/succulent/acclaim_recovery_sdcard, or the repart.img at http://raywaldo.com/2012/06/how-to-un-brick-a-nook-tablet-8gb-or-16gb/.

If you can boot into CWM on SD, I'd suggest that you "wipe /cache" (not /data) to see if that will take care of the /cache error diagnostics you encountered.
If you want to pursue the ADB route, see http://developer.android.com/tools/help/adb.html as well as http://forum.xda-developers.com/showthread.php?t=1970225.

You need to format your sd card to use
First connect the sd card to the computer and copy the files
Then format sd card to fat or ext4 or ntfs (not sure which one is supported on your device)
After formatting, copy only the required files into the sd card and then try to access recovery.
And then try to install a zip.
If you still don't get, then try to change recovery and use some other custom recovery and try to flash again.
Press thanks if I have helped.
PM me if you don't get it working properly.

That custom rom is the problem. I can guarantee it.
If you have the image of the stock rom, you have more chances of accessing your tablet.
I think you can use ADB. I personally never used ADB before. So you can search on Google and Xda on how to use it.
