Yes, but I am thinking of trying to run the battery down, leave it dead for a bit and then trying again. Ive got it on the white nook screen now and will leave it there till dead. Do you think its worth a shot?

That's seems to be how it normally behaves in CM10.1 if USB Host mode is on in Quick Settings and you plug it into power. Happened to me, and I hadn't even activated USB Host mode on purpose. Once I noticed it and turned it off the light went amber and the nook started charging.

I'm in the same boat. need help badly

My nook hd plus stuck showing nook logo during boot. I can boot with CWM SD and mount SD but not emmc.

I installed "aparted" partition manager app to partition my SD before making into a brick. It seemed that I accidentally messed up one (or all) of system partitions. The detailed symptom is,

1. i can boot with CWM sd, but no book without SD, just nook logo

2. I flashed stock rom and stock recovery, but same situation

3. I restored from my original backup, but no success in booting.

4. I cannot boot into recovery without SD.

Is there anyway to repair to original partition table? Please help me.
[Nook HD, HD+ Q&A, Help & Troubleshooting] leapinlar:
I don't know what you mean by "aparted" app. You mean in Linux? You have me confused. How did you mess up the system partitions?

Edit: I found the app. It is an android app to modify the SD partitions (called "SD Partition Manager" in Play Store). Did you somehow configure that to work on emmc?

[Nook HD, HD+ Q&A, Help & Troubleshooting] taegwon:
Thank you for response.

I was using your universal recovery with stock rom (rooted).

The last thing I did before brick the nook is below. I installed SD card partition tool app from sylcat

and tried to partition empty SD card. The SD did not seemed to be recognized by the system, so I rebooted the nook. then it stuck with nook logo.

I asked the developer of the app whether his app accidentally harm any system partition, and he replied that it cannot because system partition is mounted. I guess the app might have done something wrong to the system.

I tried to flash stock recovery and stock rom, and flashing went through without an error message. Still, I cannot boot to recovery. I tried 8 time booting interruption, no success. Then I tried to mount one by one in the CWM universal recovery after booting with CWM SD, and found out I could not mount emmc.

Is there anything else that I can try to unbrick the nook? How I can check if the system partitions are damaged?

Any response from anyone will be much appreciated.
[Nook HD, HD+ Q&A, Help & Troubleshooting] leapinlar:
The only thing I can think of is the Nook HD/HD+ has an emulated sdcard on internal memory and the app got confused by that and messed with internal memory.

Look at my HD/HD+ Tips thread linked in my signature and look at item 16. It explains the partition structure of the devices. Maybe that will help you diagnose what is wrong.

in the same boat

Well... Unfortunately......... I am in the *EXACT* same boat as the original poster. This afternoon, in effort to speed up the device, I also ran the exact same LagFix app. It hung for over an hour before I finally did the manual reboot (Power+N) and now it won't turn on whatsoever. Same symptoms as the original poster. I think this is the first time I have ever truly bricked a device before. I hope that a solution might be discovered, but based on the efforts of the OP so far, I am not very hopeful.

---------- Post added at 05:58 PM ---------- Previous post was at 05:15 PM ----------

OK - one difference here is that I replaced the stock recovery with CWM, versus the original poster had flashed TWRP.

Does CWM recovery give me any hope in this situation? All my partitions were blown up by the lagfix.

[Nook HD, HD+ Q&A, Help & Troubleshooting] jbbandos:
And I did the same. Also with lagfix, also had CWM flashed on the HD. Unfortunately, as the CWM recovery on the SD doesn't "see" the internal EMMC, I don't know how will I recover the damn thing. It still boots to SD, but that is little consolation. Of course, I had also managed to lose the SD with the nandroids I had made in the meantime (murphy at its best, suddenly that SD started giving bad sectors all over so I decided to install CWM on the EMMC, and then ran lagfix as it was terribly laggy).

My dmesg from inside the SD CWM is here. Now, if I only could see the damn emmc memory when it boots, I could beg someone for their copy of the partitions on a 16GB HD plus, but right now I am not even able to get to that point. :(
[Nook HD, HD+ Q&A, Help & Troubleshooting] talha970:

[Nook HD, HD+ Q&A, Help & Troubleshooting] jbbandos:
No idea. There are no hints in dmesg, at least that I can see. Maybe someone with a working Nook HD Plus can compare his dmesg to mine and find out what is failing to appear.

[Nook HD, HD+ Q&A, Help & Troubleshooting] jbbandos:
Seems likely, unfortunately. However, I've found that if I leave my nook connected to the pc, without sd card, and it keeps disconnecting, after 24-25 of those disconnects it shows the nook logo, as if it had been able to load the bootloader from the emmc again. I'm leaving it in that mode again for a couple of hours, to see if it changes. There could be some hope left...

[Nook HD, HD+ Q&A, Help & Troubleshooting] jbbandos:
One thing to try if nothing changes is to press the "n" key and the power button together when it shows the white "nook" on black background, to try and get it into the recovery. If that works, then the emmc should be accessible and we should be able to flash the stock image and hopefully get it to boot.

Same issue

I use my Nook HD+ strictly for reading and only install a few apps on it. I upgraded the Cyanogenmod 10.2 Nightly (from the Nightly a day before) two days ago and when I tried to use it a day later, the screen wouldn't come on. I've tried using my MicroSD with CWM 6.0.2.8 and Cyanoboot, but am getting the SD error saying it cannot mount /cache/recovery/last_log and the sd card won't mount either (on Nook or PC/Mac). May try another sdcard with a fresh install to see if it'll come on, but that's where I'm stuck. Not using the lagfix app, so I'm wondering if it may be something else that could also be causing the issue for us.
[Nook HD, HD+ Q&A, Help & Troubleshooting] Sherip:
Yes, 10.2 had the functionality of the lagfix app built in and running automatically under certain circumstances. The functionality was disabled in HD and HD+ nightly builds of 8-16 and after, and in the unofficial SD card build dated 8-15 and after.

We've speculated there may be faulty Samsung emmc components in some or all HDs and HD+'s. However the part identified is not on available lists of emmc's with "brick bug".

[Nook HD, HD+ Q&A, Help & Troubleshooting] jtnave23:
Thanks for the reply! So if I'm able to get it back up and seeing CWM, I will need to go back to 10.1 Unofficial or to a nightly build after 8-16? I don't mind wiping the device as I have all my main docs on an SD Card. I may even go back to the stock rom if needed since I can do most things thru the stock OS (even though it lllaaaggggssss). I am getting the can't mount /cache/recovery/log error on CWM SD card, so I'm trying one solution of redoing CWM in hopes that it'll function properly.
[Nook HD, HD+ Q&A, Help & Troubleshooting] Sherip:
If you can ultimately get back, the latest nightly for 10.2 will be fine imo. Restoring or installing stock might be an intermediate step.

Meanwhile, you should know that Verygreen has created a CM 10.1 SD image that doesn't need access to internal storage http://xdaforums.com/showthread.php?p=44790925 With that you can still use the tablet even if the internal storage is shot.

In order to make the card you will need to have adb installed and working on your PC. He's suggested this for assessing the status of internal storage to someone else getting the same cache error as you (edited here as the wrong link was originally pasted) http://xdaforums.com/showthread.php?p=44796226

Look for leapinlar's Tips thread in the General topic area for some guidance on installing adb.

Which recovery do you have on internal storage? If stock, you could try the 8 failed boots routine to invoke a factory reset. Leapinlar has stock and stock recovery zips (and a different version of cwm) in his [Stock/Root/cwm] thread in the Android Development topic area. You could try those as well.

For leapinlar's threads, the info and applicable files are in the first message of his threads.

Thanks for all the advice Sherip! Unfortunately, I've either got a bad SD Card (all the rest are 32GB and I'm not using those for CWM) and am still getting the same error messages and no OS. I was able to get a NOOK boot screen but it wouldn't get past that. I then decided to take it to B&N and they swapped it out for me.

I think this is the best place for my problem. Anyone please feel free to redirect me as necessary.

Did SD install of CM 10.2 on Nook HD+ in November 2013. Things worked well enough for my purposes until recently. Got caught in bootloop (/bootdata\BCB missing) and nook always booting into CWM recovery. Followed leapinlar's directions from here and made a new CWM recovery SD (although my old card was booting here anyway). Also loaded the NookHDplus-emmc-stock-recovery-rev0-(05.16.13).zip with plans to flash the zip and fix the boot problem. Put the fresh SD in the nook and it boots to CWM recovery, but then cannot mount the SD!!! Also checked and I cannot mount the emmc.

I am fine going back to stock if possible so here is my question.

Can I do a "wipe data/factory reset" while unable to mount the sd or emmc and will this fix the bootloop issue? Is there a better or simpler fix?

Thanks

EDIT problems are not related to lagfix
[Nook HD, HD+ Q&A, Help & Troubleshooting] leapinlar:
A factory reset will not fix your problem.

I'm not sure what you mean by can't mount the SD. You ordinarily don't try to mount that yourself when you try to install something. Or are you saying you get an error message saying the sd will not mount when you select the install from sd menu choice?

I know this probably not the answer but i had trouble with SD card not working and i used SDformatter to format the card then Mini partition tool to set as active then it worked, before that i couldnt flash any zips from card. Also will a hard reset work on Nook if you have CWM installed (top right button, power button and n button at same time then release power button once Nook boots.
[Nook HD, HD+ Q&A, Help & Troubleshooting] tinkering:
Tried the hard reset technique, but the Nook just booted to the CWM recovery. I'm thinking in my case the problem isn't with the SD card itself.

Thanks though
[Nook HD, HD+ Q&A, Help & Troubleshooting] tinkering:
I went ahead and tried the SDformatter (Full Format) and Mini partition tool to set as SD as active. Wrote CWM to SD and loaded a zip. Still getting the error message cant mount /sdcard/

After this, I guess I can rule out the SD. I think I can rule out the CWM as well.(I tried 2 versions 6032 and 6028). I suppose that leaves the nook hardware as the culprit? Any other possibilities I am leaving out?

My nook is under warranty. I'm concerned about taking it to a B&N though because if I take the SD out it won't boot at all. Anybody tired to swap out a nook in this condition? Any luck?

EDIT: Maybe I'm overthinking this one. "Broken" is probably the condition in which all Nooks are exchanged under warranty
