I had FroYo running on eMMc and all was running smoothly until I went to reboot it and now the screen will not turn on. I have held the power button for a long time and tried pretty much every button combination to get it to power on. I also tried plugging it in and still nothing. Is my nook bricked?
Have you tried booting Froyo on a SD card?
If you don't even see anything on the screen maybe it's a hardware failure..
Were you overclocked?
I put froyo on a 2gb card and i still cant get it to boot. Is there a specific key combination i need to use to get it to boot off of the sd card?
Are you sure that battery wasn't almost dead? Try booting it while plugged in for a bit.
I've had it plugged in for about 10 minutes and ill try to boot it in a second. Whats my next course of action if that doesnt work? and thanks for the suggestions so far.
Still a no go on the boot. Im going to let it charge overnight and give it another go in the morning.
when I power my nook on by holding down the power button eventually the screen will "light up" (even though it will stay black, you can tell the backlight has come on). is it doing that, or just never seems to respond?
I had an issue once running Nookie Froyo where I thought my Nook was dead and realized it was actually on after a while. Only way I found it was that I saw it on my network via my router when checking something else. No matter how long I held the power button down it never seemed to do anything. After a while of fiddling the screen finally lit up and I could get in.
If you plug it into the USB port on your computer, does the computer see it and load the driver for it?

Unless you're using the B&N supplied cable, the NC takes a REALLY long time to charge. I inadvertently let my battery drain and tried charging it using my EVO's USB cable and still couldn't use it more than an hour later, with the "try again in 15 minutes" warning on the screen the whole time.
Hope you managed to fix your problem and that your NC is functional again.
I had the same problem and I could actually replicate it. I had froyo running emmc. What I did was clear out some cache and data from market, Google framework, and also the download manager since I had the market download unsuccessfully problem. Right after I cleared the cache and data then force close the Google framework application (and of course reboot), I couldn't turn on the nook color anymore. I know the device wasn't dead because I got feedbacks if I do.SSH. I flashed the rom again and it came right back on. Then I did the same steps for the cache and data, the device once again couldn't turn on.
Ok i let it charge overnight with the b&n cable (the light was green this morning) And I tried to turn it on again. The screen still does not turn on and the backlight does not turn on. I do not get any response from the computer when I plug it in. I think that I may have bricked the hard to brick nook color :/
I ran into this very same issue a moment ago, and I just followed these steps:
http://forum.xda-developers.com/showthread.php?t=931720
In your case, you want to install the CWM to the SD with the nook 1.0.1 software zip, insert the SD card into your nook, then press and hold down the power and the N button ... and it should boot into CWM then continue with the rest of the steps.
Thanks for the help everyone. I think I may have had a coincidental hardware failure. I took the nook color to b&n today and they tried everything to get it to work and they were going to try to send me a refurbished one, but I asked for cash instead so they gave me a new one on the spot. I am going to stay away from the froyo stuff until it is a little safer (hopefully I can hold out until CM7 comes out)
I can confirm this is definitely a problem with the current Froyo build (.6.7). After loading it to my EMMC and loading Google Apps, I had the blank screen, no reboot issue after I sent the adb reboot command. Thinking I had bricked it (charging, holding the power button, etc. wouldn't do a thing), I popped in an SD card with bootable froyo on it and now the thing powers on and boots to SD. If I take the card out, it goes back to it's dead state.
I'm downloading the stock FW and going to reflash it, but I just wanted to confirm that this is a problem and it probably wasn't a coincidental hardware failure.

I'm having the same issue. Nookie Froyo .6.7 on emmc. Completely dead and not recognized by computer usb. Will try the SD bootable froyo.
Edit: Ok, I was able to boot off the sdcard, but can't get to recovery. If I remove sdcard it won't boot. I guess I'll have to put the recovery on the sdcard to reflash a rom.
I had the same issue when using Froyo 6.6 to EMMC.
I really thought I had bricked it and out of Desperation I made a CWR card put it in and tried every button combo I could think of and low and behold it booted back up. lol, now I'm back to stock 1.1 rooted. I think I will wait till CM7 is out for the nook before writing to EMMC again.
But man props to the makers of the nook color, 99.9% Un-brick-able
Yeah I had a couple issues with throwing an image on the first time I went to root it, just re-formatted and put a diff image on the SD and everything was fine....
Ugh, I'm glad I'm not the only one having this problem. Now I get to walk through the recovery.
Update:
So after walking through the recovery, I still couldn't get it to boot. It wasn't until I performed step 5 that it finally worked.

I did a search and couldn't find any other topics covering the same issues I'm having, both here and a general Google search. I also called my mother, and she did indeed say I was special.
Anyway, bought a Nook HD+ two weeks ago and left everything stock for a few days before using Bokbokan's Hybrid SD/EMMC. Everything worked great and enjoyed it for a full week until my Nook started freezing and getting an odd ghosting and slow refresh on the screen.
Figured it was a rom issue so I removed the SD but even when powering it back on the screen had the same effect. And it continued into the stock rom. I de-registered and returned to stock and still had the same issue. Washed out screen, slow refresh, slight flickering an odd randomish burning which held even when the device was powered off and left off for hours. Used the HDMI adapter to see what happened and the output to the TV was fine, making me think I just had a defective screen.
So I returned it for a new one. Followed the same path. Stock a few days, then hybrid install (with the newer Bokbokan rom). Ran great for another few days until I had the screen freeze on me. Not ghosting like I had before, just lines like a disconnected ribbon cable. I reset a few times though and everything was fine. The next day it did it again but took removing the SD card and hard resetting into stock to get it to fix the screen. Then a few hours later I could only get it to boot into the stock rom with a normal screen(CM10 would always have lines and be unusable before it even started booting) , but would go out after 30 seconds. Booted into CWM from the SD card and the screen was fine so I did a factory wipe and left out the SD and booted into stock. De-registered before the screen went out and started over. Started re-registering it and the screen would start going out after the 30 seconds but then snap back to normal after another ten or on a new screen. Once it finished setting up my BN account I reset and... now it seems to be running normal... Left it sit like this for a few hours (checking it every few minutes) and I haven't had a single issue.
This seems to me to be something I'm messing up. I can't see having two defects like that in a row, when I know other people who bought the same week/store from me and haven't had any issues (also running the same Bokbokan rom). And the fact that it seems to fix itself the longer it sits in stock. I haven't dropped it. There has to be something I'm not thinking of that's causing the issues. But I'm completely out of ideas.
Is this maybe some kind of new anti-rooting thing by B&N? Does someone have a voodoo doll of my Nook? My SD card have some type of bacterial infection? Maybe a full blood moon overhead? An allergic reaction to my screen protectors?
Any ideas?
Do you have some big magnetic source or other device in your house that could be effecting your HD+? Just grasping for straws. Never heard of this before.
You might try verygreen's NEW SD scheme and see if you get the same thing.

My case does have a magnet in it, but this started before I got this new case.
But the way the screen looks is the way a screen looks like when it needs degaussing... But wouldn't explain why it only clears up after running a fresh stock rom for a bit.
Which has me thinking now it is something wrong with my rom. Even though both Nooks used different roms. I shall try using verygreens and see what kind of results I get.
I hate problems like this. =p
I'll report back in a bit!
Ran my Nook wih N2A card 32gb for a about a year . Recently, it started overheating on the lower left side. I tried to reboot but it hanged on the boot screen and then shut down. I thought it was the Black Screen Of Death
So, I tried the many power button and "n" button configurations but none worked. I eventually opened it up and removed the battery and plugged it back in after 30 minutes thinking it would reset but that still didn't work.
The battery has full charge so I ruled out the battery being dead. I decided to plug it into my laptop USB and that is where I got the Nook trying to install a driver.
Got the message "Device driver not successfully installed" OMAP4770 Device unplugged
Tried it without the sd card but still the same message. I tried my N2A SD card in my wife's Nook Hd+ and it works perfectly. So that was ruled out.
Is there any way to revive my nook? I'm sure there is someone who can help me.
It is normal for the device to get hot on the lower left. That is where the microprocessor is and if working hard it will heat there. And the Nook HD/HD+ does not suffer from the SOD problem like the Nook Color did.
Since you supposedly still have stock recovery on internal you should be able to do the 8 failed boot procedure. Just interrupt the boot 8 times in a row by hard powering it off (hold power key several seconds) part way through each attempt to boot. On the 9th try it should try to boot to stock recovery and reset itself.
If it won't do that you can try making a new bootable CWM SD per item 1a from my HD/HD+ CWM thread linked in my signature. If that boots, use it to flash a plain stock zip from item 6.
If those don't work, I think your device is toast. I would recommend a warranty exchange with B&N but it sounds like it is over the one year warranty.

I recently decided to go back to complete stock. I wanted to see how a factory stock rom would deal with the battery issues and others I've had. That's where the problems really began. I followed the instructions in a current thread. I used this thread years ago to root my nook without a problem. My Nook HD+ this time would not boot from any SD card. It did not matter what image I used or what method from the mentioned thread. The SD cards are good though. I stupidly did a factory wipe/reset in CWM, mostly because I had tried everything else. I knew not to do it, but I had tried everything! My Nook would stay on the Caynoboot after this. I finally got a flash to work using the old method and CWM 6028, but this time it hung on the Nook screen. After fighting this for a while, I finally got the stock recovery and stock rom to flash. Great, it's working again as it should. The problem I have now is if I leave it alone for a bit the Nook will shut off. I can power it back on, but sometimes it takes a couple of tries. I tried to charge it this morning when the battery went down to 6%, but I could not use my Nook charger. It would shut off or start to boot past the Nook screen and then shutoff. I'm typing this now and my Nook is charging fine through my computer. Has anyone experienced the auto shutoff when leaving it alone? It's totally annoying, but it functions fine other than that. All of these problems came to life after going back to stock root. Personally, I don't feel like starting over again. I'm to nervous that something will go wrong.
My thought is this relates to all the known battery problems the Nook has. CM might eliminated some of the obvious though. Mine started 3 months after I bought it years ago. It was part of the reason I went to CM10 at the time. I thought maybe the factory rom was the issue. Do you guys think the auto shutoff and normal charging method issues are battery related? I don't think it's a hardware issue. It could be the way the rom was finally flashed, but I would expect more problems other than the above. One thing the factory rom did fix was the Nook shutting off on almost any flash video. It was always random, but this has not happened since going back to stock.
Wow. This just gets weirder and worse(r). We've been running first CM 11 and then CM 12.1 on this HD for awhile and all was fine. Suddenly the battery indicator became wonky, dropping from 50-ish% to 1%, precipitating a shutdown unless the tablet was immediately plugged in. Then suddenly the battery indicator would return to normal and you could unplug the tablet.
Next, after running a backup on the CM 12.1 ROM the tablet started crashing during boot (the cyan android phase) UNLESS it was plugged in to the power supply (USB to computer is not sufficient). This, despite a good charge level on the battery. After a minute or so when the boot was complete, you could unplug the tablet and go on your way.
Today the screen flashing began. Makes the tablet completely unusable. Sometimes you can calm it down for awhile by connecting via USB to computer, sometimes not. This thing is freaking me out. I just recently took the tablet all the way back to stock and resintalled CM 12.1 from scratch, including building a new SD card from new files. Before someone asks, it's a class 4 card. I've always been fine with Class 10 or UHD cards when working with my Nook Tablet, but for some reason I decided to play it "safe" with the HD and hunted around for a lower class. Maybe a mistake?
Finally I took the tablet back to stock again today, completed the sign-in process to the old B&N account and everything is fine. No screen flashing, no funny business with the battery indicator, no problem booting without the power cable.
I just ordered a "new" (out of box) replacement for the tablet on ebay, but it doesn't seem like this is an actual hardware issue.
What scares me now is a potential repeat of this process with the new tablet. I've never had any experiences like this with my old Nook Tablet. I'm at a complete loss.
Help!
Edit: OK, we seem to have tracked down the general source of the screen flashing. The backup we have been restoring is from July 2017 so quite a few apps want updating. We noticed things would be fine for awhile and then the flashing would start. At one point "Unfortunately Google Play Services has stopped" kept popping up. I began to suspect either a bad or incompatible update was messing with the system. So...we did another restore of the same backup but immediately turned off auto-updates from the PlayStore. Three days later and no display flashing. One small victory.
Could the shutdown during the boot animation be caused by a corrupted file? I don't see how since it boots OK when plugged in, just not on battery, but I'm willing to pursue any possibility.
Edit.Edit: Well, well.... We got a "new" open-box HD from ebay and I started working on it. I noticed in making new SD cards that one I had been working with was not properly set to 0x0C FAT32 LBA. I fixed that. This time the tablet will boot into the OS without being plugged in! Yay! Still have to test that on the old one after I finish building a duplicate system.
I'm restoring apps and everything is fine until suddenly the flashing starts up again. But now I know when it did. The offender seems to be the 0.15 version of Lithium Epub reader. I managed to uninstall that via ADB (with screen flashing you can't do much with the tablet except ADB). Voila, no more screen flashing. I found a copy of version 0.13 and installed that. No flashing screen. Needless to say I've set the app to not auto-update.
Edit.Edit.Edit: Well, $40 later we now have a second Nook HD and both are running fine. Hard to imagine that the goof that somehow happened to the SD card would manifest as only being able to complete boot when plugged in, but that must be it. Returning to stock (tried that...) and reflashing with the newly prepared SD card did the trick. Moral: sweat the small stuff.
