Fixing NT stuck with CWM, restore / update won't work

[towir022]

I am trying to do the fix that this thread is about however I am unable to get ADB properly working. As of now when I do adb devices it does not see any devices so clearly my nook is not set up right for some reason. Any ideas would be great. the klindle is in CWM when I try to do the ADB

Boot Loop

I recently tried to reflash my Nook Tablet 16GB to the latest version of the CM10 alpha, from 0.06 to 0.08.1. Unfortunately, the update may not have downloaded correctly due to the wifi + charging + stand-by = unmount bug.

When the new ZIP was flashed, the tablet will not longer boot past the CWM-based Recovery v5.0.2.8 . If the charger is plugged in, it will reboot a few times and then boot into Recovery. Otherwise, the screen will briefly illuminate, and then go black and off.

I've tried flashing various ZIPs through the Recovery panel, but none have had any effect. If I attempt to boot from SD (formatted using instructions from some of the SD recovery threads), it simply redirects my to the internal SD's CWM bootloader.

I suspect that the partition table is corrupted. However, it seems that my only option is to issue commands via Fastboot, which appears to run from Recovery. Unfortunately, ADB/Fastboot on my PC cannot seem to find my Nook Tablet . I've tried installing the USB drivers but Windows 8 rejects the included CAT files, saying that the hashes are missing and that they may have been tampered with.

I'm pretty smart, and tech savvy, but I'm getting worried that nothing will work. Help?

It is the same for me.
The driver is not installing at all for the tablet.

This is what I am trying to do:

Created a CWM SD card from this thread : http://forum.xda-developers.com/showpost.php?p=25786947&postcount=1
Then I booted the NT in CWM through the cynoboot and loaded the sdcard recovery

Then I plugged it into the PC
Went to device manager and tried to update the driver

The driver installation failed by saying the driver is not valid.


Is there a step I am missing?

Hello all,

Hoping someone can help.

I have bricked my nook, at first it was stuck at the "restart the nook and try again screen" and would only boot into SDcard with CWM on it. I tried installing stock NT roms with CWM, wouldn't boot into it, keep getting "restart nook..."

Now I have internal CWM and it only boots to it, wouldn't boot past it, even after installing CM7.

adb does recognize(using ubuntu on virtual machine) the device and followed this post with the parted commands. Here is what I see:

Number  Start   End     Size    File system  Name        Flags

Do you get any other errors or questions on screen before it show you the list of partitions ?

thanks for the reply!!


I did but don't have it up right now... I did it yesterday, I got the error saying that I needed to fix the partitions so just said yes to fix them. So I thought they were fixed?

it fixes a few things yes. Not all. When you get back to it try again and see if there are any other errors... If there are, post them here

I am in it now, I ran the parted command and don't get any errors, just a list of my partitions. The nook still only boots into internal CWM.

Thanks for your help!

 

[CelticWebSolutions]

Have you tried the full stock restore now that the partition table is fixed?

 

[shellsac]

Have you tried the full stock restore now that the partition table is fixed?

I have tried so many things, which one are you referring to? the acclaim_update?

Any rom that I install doesn't work because I can't get it to boot into it, the NT just boots into CWM.

suggestions?

 

[traversc]

Thanks for this! The repartition method successfully unbricked my nook. Now if only someone could fix the problems I'm having with CM 10

I have a 16g Nook tablet. This is where I'm at with it. I can use an sd card and boot into cwm. I can also boot from sd card and run cm7, but it is terribly slow and very buggy, even with a new 8gb class 6 sd card. I believe the partitions are messed up and have to be fixed. I can get my computer to see "Nook Tablet /!\" but once I install the drivers (I have installed the older ones and the newer ones with the same result) "Nook Tablet" goes away and "Android Phone" pops up and under this heading is listed "Android Composite ADB Interface". This is all done after clearing all the usb mass storage and such devices using USBDview. By the way this is being done while the tablet is in CWM so I can't check or uncheck USB debugging. Can someone please help me with this? Tell me what I should do and how to do it. I was going to do what it says in the first step of this thread, but don't know how to use DOS very well. Any help would be much appreciated.

One more thing, what its doing when trying to boot up is "N" screen then "Please dont turn off device..." then the red exclamation point screen saying to try again or contact customer service.

+1000.

this is exactly where i'm at with my NT. it comes up as android phone in windows, adb will not recognize my device no matter what i do (comes up empty when i type adb devices), i can only get into sd version of cwm but get the 4 or 5 error messages at the bottom about not being able to access recovery folders, and when i turn it on with no sd card in, i go to the installation screen with the red exclamation point. i've tried a lot of things and believe it is the partition tables, but cannot get adb to recognize to push the parted commands. i've tried every driver listed in every thread, bounced back and forth between "nook tablet" to "android composite interface" to "usb mass storage device" any help would be greatly appreciated. 16GB btw. thanks.

ok i downloaded an external cm10 image and tried to start it from the sd card, but it gets stuck at the swirling cyanogenmod logo. i formatted the partitions when it was working and i'm pretty sure thats why i'm stuck here. i've tried everything to get this working, including the flashing of partitions 1-4 & 6 in cwm, and that said successful, but when i try to install b&n 1.4.2 after that, it just gives me the red exclamation mark with the message to contact b&n. plus i still get the unable to mount recovery cache messages in cwm.

its possible the reason the adb isn't working is that i never turned on usb debugging when it was working properly, but now that i can't get into any version of cm, how can i enable it? i do see it in windows like i said, just when i run adb devices it comes up empty... so i can't partition anything manually. only thing i can get into is an sd mounted version of cwm.

sorry for the thread hijack and i know this is the general forum and not the q&a forum, but i've run out of options here and appreciate any help. thanks.

I have adb working. I am just confused as to what exactly you are supposed to do once you see in adb. The directions in the first post only list one command .

Can anyone give super basic instructions of what to do once you are in adb? I get into adb type adb devices it sees device and then i don't get where to go from there

Let me give some more info. I go into adb type adb shell then simply put in the code parted /dev/block/mmcblk0 print and it talks about gpt tables and asking if this is a gpt partition table.

I extracted those parted files which are named 0, 1, 2, 3 or whatever I put those files just on a blank micro sd card and stuck it in the nook. When in adb do I first have to mount the external sd card? Or do I have to tell adb where those 0 1 2 3 files are located or something for this to work?
Here is a pic of what I have going on. I am not sure if I am doing it right. I dont even think adb or the nook knows that there is an sd card in the slot or that there are important files on it for that matter.

I attached a picture of where I am at with adb

Wow, after so much time I am lost

I installed CM7 a LONG time ago on a Nook Tablet. I honestly don't remember the steps I had taken but it completed successfully. I then lost interest in my NT and gave it to my wife. She used it quite often and eventually she didn't charge it and it went dead. Upon re-charging it, it would start, I would see the CM7 logo then it would stick on that Team B logo.

Now, I have CWM Recovery installed internally and it keeps booting to that.

I tried this SD image and instructions http://raywaldo.com/2012/06/how-to-un-brick-a-nook-tablet-8gb-or-16gb/

But that did not work. I don't get a green check mark and it just says "Rebooting in 5 seconds" then it never starts up again.

I hate to sound like such a noob because I obviously got involved in this before but now I am totally lost.

Can someone please give me step by step instructions (even if you have to point to other posts on how to install ADB since I don't even remember what that is), on how to get this NT back with CM7 or whatever the latest stable version is? I tried following this thread but it assumes that the reader has already done things, and I haven't. I'm basically starting from scratch with a bricked NT.

I should also mention, I have changed PCs and have never hooked the NT up to this particular computer. I no longer have the one I originally used.

Again, I apologize, I'm usually not this noobish.

To fix a boot loop to Recovery, I'd suggest that you use SDcard-based CWM to flash flashable_fix_bootloop.zip from https://docs.google.com/file/d/0BwFA9QwlHuiIUEJrM19RaFJBMk0/edit (click on File->Download to download).

If you'd like to flash the most recent & stable CM, I'd suggest you try Succulent CM10.0 build dated 12/31 posted at http://iamafanof.wordpress.com/2012/11/03/cm10-0-jelly-bean-for-nook-tablet-uploading/. See http://forum.xda-developers.com/showpost.php?p=35669871&postcount=1 for info/pointers on how to flash ROM internally.

And where is a SDcard based CWM image I can use? I did download the other file you posted. However, my SD card won't mount now.
I found one method that insists on running Ubuntu to do it. If I have to go to those lengths to make this thing work again, I may have an expensive paperweight.
