I've read through the Dummies Guide and researched plenty of posts. The Nook will not boot by itself or with an SD card:
1. The SD card boots my other Nook Color just fine.
2. Have tried multiple boot images 128mb, 4gb, 8gb, and the CW 1gb. No go.
3. Tried 8 failed attempts (but without seeing anything on screen I do not know if I did it right)
4. Tried Multiple combination of holding power, n, volume buttons.
5. Disassembled Nook and disconnected the battery overnight.
6. Fully charged battery afterwards and nothing still.
7. Tried all this with and without a bootable SD inserted.
Computer does the whole recognize OMAP 3630 for a split second and loses it. From This Thread, I gather that I might be bricked. However This Guy seemed to have come back from this state. I am a little unsure as to how. I couldn't quite understand his final post about how he fixed it. It sounds like he just found a different boot.img (which I also tried ..... i think) and had finally found a SD card boot image that worked.
I have exhausted my research ability. I have no history on this Nook. I bought my working Nook off Ebay and the seller just threw this in with it along with a error 28 Ipad. I just hate to be defeated by an electronic. The only thing I have not tried is actually replacing the battery, but it seems to work fine. It discharges and recharges. So I am not sure where I stand on this. I believe I have tried everything, but maybe a Nook's nand is like an finicky Xbox and I can short some pins or something to give it electro shock treatment.
Anyway, I have absolutely no problem trying "crazy" ideas that risk frying this thing. Maybe I missed something, maybe I haven't. I apologize if I posted this in the wrong section.
I have a Nook that experienced everything you're saying.
After trying everything multiple times and getting nowhere I assumed it was a hardware problem.
I got a new motherboard off of ebay and replaced it and it's been fine ever since.
I'm not sure which part failed though since everything's integrated on the one board.
I'm going to go through and play with the board a bit. Time to test for shorts.
Hello all,
Been a satisfied user of nook hd+ with emmc. Yesterday, leaking water from my bag soaked my sleeve that I put my HD+, and as a result, I noticed that the HD+ didn't turn on after that.
After a day or so of drying and powering (with no luck), I plugged the device to the charger. Then I saw the green light and the red light flashing multiple times. On the screen, the nook sign turned on as well as the cyanomod introduction screen. However, after that, the device shuts off completely. The system didn't respond to the power button after that, and the charger indicator light didn't turn on after that. I tried leaving the charger on all night but same pattern showed.
I suspected that due to the liquid spill, something happened to the internals that effected the battery.
Now my questions are:
1. Does Nook HD+ deal with spills in the warranty(don't think so)? If not, is there a spill sensor (like the iphone and samsung phones where if it gets wet it changes color, etc) ? Can local barnes and nobles stores deal with device warranty, etc?
2. I remember that warranty also involves the machine has to not be rooted, etc, and therefore will have to be brought back to factory settings. I will have to check, but if I didn't make a stock backup of my own, can I still put an emmc cm10.1 device back to factory settings using the files available in xda? I did register my device via nook servers.
3. As a followup to 1, if there is some drying and/or reassembly required, are there any videos or instructions on opening the cover of the nook hd+? I only saw some videos in youtube for opening the nook hd color, but couldn't find any on hd+.
Thanks to all the help in advance.
I'll answer your last question first. There is an HD+ teardown thread and video here.
Your local B&N store can deal with warranty. They just look up your serial number to see when you registered it and verify it does not work and they will issue you a new one.
But you are right that putting CM on it voids the warranty. If they can see any evidence it has had CM on it they will not honor the warranty. But yours does not power on, so I'm not sure they can tell.
If you did not replace the stock recovery with either verygreen's or my recovery, you might be able to do an 8 failed boot reset, but it sounds like it does not even power on.
And if you can boot to your CWM SD, you can put stock back on it by flashing one of my stock ROMs in my HD/HD+ CWM thread linked in my signature. But I suspect you cannot boot to it.
Thanks Leapinlar for the fast and informative advice. I will follow your steps and update the post if necessary.

Actually, I do have an issue right now though- I find that when I first plug the charger in, I see the "nook", then the "cyanoboot" screen briefly comes up before it shuts off. Now I would have to assume that the BN rep will check by plugging the device to see if it doesn't turn on, and will consequently see the cyanoboot screen. Is there any way I can at least get that screen to just display nook? I have yet to try plugging the cwm sd.

The only hope you have is if you can boot to CWM SD. But that cyanoboot screen gives me hope. You may be able to repair it with that.

Alright, I tried putting in the cwm SD, and what happens is that it gets to the main menu. I got it to the "factory reset", and it says wiping /data.. but after that the thing shuts off. When I take the SD out and restart, sometimes it actually fires up the device all the way to the beginning screen, but then shuts off. During this brief moment I noticed that the battery meter was shown at full.
I also called up the local BN and found out because I bought it at a different store other than BN, I won't be able to get it exchanged- I would have to call and register a claim.
I guess now my main issue now is to wipe out everything somehow, or at least get rid of the beginning cyanoboot screen, so that the corporate nook won't notice this issue.
If nothing I am planning to actually use the steps to open up the casing and attempt drying out whatever precipitation is left and hope that it will work. However, I am worried that they will notice the casing has been tampered with and void my warranty.
Any help and/or more advice will be helpful!

Wiping data does not really help. See if you can flash the stock recovery from my HD/HD+ CWM thread, item 5. Then see if you can flash the stock zip I also have there.
And that is BS about B&N not honoring the warranty because you bought it somewhere else. I bought my HD at Target and registered it with B&N. I had a problem, took it to B&N, they looked up the serial number, saw I registered it less than a year ago and they gave me a new one. Before I did that I had asked an associate there if I needed the receipt and she said no, they just look on the computer, and if I did not have an extended warranty from Target, they could take care of it. And when I came back a few days later, that is exactly what they did.
When you take it in to your store, since they seem to be finicky, don't mention where you bought it or show them your receipt.

Pour some more water into it. With some sugar.

Yeah I tried flashing your zip file, but now the response never even gets to reading the sd card- it just shows the nook icon, then the cyanoboot icon then turns off. Taking the sd card off or back on doesn't change anything.
Thanks for that info involving the bn. I am planning to go to a differerent bn location tomorrow to see if they will see. One thing though- do you remember if they plugged the device to check? Or do they just type in the serial directly? I am just a bit nervous about if they will try to boot it and see the cyanoboot icon and refusing the replacement.
Will update later. As always, thanks for the suggestions.

They plugged it in. I would not take it in unless you can get that cyanoboot off.
Were you able to flash the stock recovery? If so, try booting 8 times in a row without the sd in, it may repair itself.

Unfortunately no, I wasn't able to flash the stock recovery. Before, the cwm boot screen from the sd came on, but now it doesn't even do that. Also the bad part about my issue is that the power button actually doesn't do anything- I have to plug it back in and out for it to show something. (nook icon-> cyanoboot screen, turning off)
I am wondering if opening the cover at this point is the only method left in order for me to get it to respond at all, perhaps disconnecting the battery or looking for wet terminals.. not too sure hwo to do this without making it visually shown that I tampered with it.
But I will also heed your advice and not take it in unless I can get rid of that screen. thanks
Or find a way to make sure it does not boot at all

Yes, open it and disconnect the battery. Lol.
And if you use the right plastic tools, it may never show that you opened it.

Alright, here is what happened. I actually ended up taking the front plastic cover off. The adhesives were a pain to deal with as I took the cover off, but I luckily had some of the tools as outlined in the teardown article you referred me to.
Surprisingly, removing that casing somehow enabled the nook to respond without shutting off.
Fearing that it might shut down again, I quickly used the stock cwm sd with the full recovery zip (400mb file) and reflashed it to factory settings. Now the cyanoboot screen was gone, although the nook screen froze at the 99% mark.
Following earlier advice, I went to a different barnes and nobles(not the one I called and got shot down from lol), and it was relatively okay- a rep actually wanted to see the receipt, but after pressing my case about warranty repairs not requiring it, they decided to take it anyways and replaced it with a BRAND NEW sealed nook hd+. Having the box helped the situation as well, since appraently it simplified the exchange process from their end.
all in all, I was able to get my nook replaced via warranty, thanks to the help here and the files available for flashing!
Thanks again for the help
Set the HD+ on a warm surface for awhile (top of PC, top of cable box, etc.) the heat may help the moisture evaporate.
That is really good news. Glad things worked out.
If your new device boots easily to an SD, you might want to keep stock recovery on there so it can reset itself if there is a problem. Go ahead and put CM10.1 on emmc, but stock recovery allows an automatic restore to stock ROM if things go wrong.

Glad to know your issue is resolved. I also learned from you that B&N has better warranty policy than ASUS. I just sent my nexus 7 to ASUS due to a thin green line on the screen. On the RMA instructions they clearly said water damage is not covered. I had to spend about $10 to ship it back and it is still under repair (status shows repair in progress) after 3 days.
Yeah I might go ahead and keep the stock recovery there so I can indeed reflash if anything goes wrong- obviously it did occur.
Thanks again.
@View92612- actually I am not sure if nook covers it against liquid spills either- in fact, I wouldn't be surprised if they didn't. This was also the reason why I was thinking of opening the device up to make sure there wasn't a liquid spill sensor like many cellphones do nowdays.
Remember also that technically- in house exchange is ONLY valid for devices bought at B&N. It is clearly a store-to-store, situation-to-situation basis, as I have found out (see my earlier posts for proof).
Hope you get that ASUS properly repaired. I remember hearing not so good repair stories for asus and acer products due to repairs having to happen overseas.

Thanks for the reminder. My Nexus 7 just came back with a beautiful, brand new LCD with a part number label. Apparently the easiest way to fix a screen problem is to simply replace with a new one. It went to Grapevine, TX which is right next to the DFW airport. I hope my Nook HD+ would not have a similar issue later. But having a B&N store nearby(about 5 minutes from home) is quite helpful in such scenarios...
Help. Since about a week and a half ago my Nook HD+ has started shutting off primarily when watching a video or listening to audio. The length of time it takes to shut off varies.
I thought it was a problem with the nightly build of Cyanogenmod but I kept updating the rom nightly and nothing fixed it. Yesterday I installed Slimbean (with the new trim kernel and without overclocking) and although the performance is better it still shuts off during a video or listening to audio/radio.
Ok now that I mentioned the kernel thing I know some of you might suggest using the original rom without the new kernel. I will. Are there any other possible ideas that you guys can think of?
I am just starting to fear that perhaps my nook has an internal problem. I bought it from Best Buy with no warranty and I don't have the receipt. Not that it would matter, because it's been more than 2 months. I'm guessing there is a manufacturer warrant?

If you bought it new from BB and registered the stock software with B&N before you put CM on it, yes it should have a one year warranty from the date you registered it. And you do not need a receipt. But you must have stock back on there before you take it back to B&N for exchange.

Is this a hardware fault? My previous Nook HD+ no longer charged. Nook took a look at it, then issued a warranty. I now have a new Nook HD+, which I gave to my father. I've installed stable CM10.1 on EMMC, and my father says the Nook often turns off, at random times. I'm not entirely sure why, it's a brand new Nook.
Why would I have had to register it with the stock software that came on it? Wouldn't it be possible to do the same thing if I put the stock rom on it again? I just honestly do not remember whether I registered it. I think the first thing I did was try to put CM on it.
I think I figured out what the problem is. Apparently when the volume is too high (it depends on the video) it crashes. It doesn't have to do with the volume bar or what percentage it's at. It has to do with the actual amount of sound coming out of the speakers. I've been able to watch videos on youtube completely with the volume at mid level.
My guess is this is causing the nook to rumble on the inside and something is making contact causing it to shut off.
2nd Edit: So I opened up the nook while still having it on to try to separate the back from the speakers and it worked fine with loud videos and everything. I put the nook back together and everything is working fine.
I have the same problem with my nook hd+. I'm curious as to whether you were able to solve this problem permanently.

If you think its the sound coming out of the speakers then wouldn't headphones/speakers in the headphone jack be a worthy test since they are not part of the device?
Anyway, my first guess would have been a battery saving app that was forcing the display off. Could happen; Future reference.

Sorry for the late reply. I haven't logged into this forum. Yes, my Nook HD+ is still working fine. Have not had to open it up again.
I am having a very similar issue with my Nook HD+. I just converted it from stock to CM11 using cm-11-20150712-NIGHTLY-ovation.zip. As a note, I have never had any problems with my Nook HD+ running on stock since I got it a couple of years ago,
I thought everything was running well after I flashed the CM11. First, when I was using Google Voice Search, it completely and suddenly just shut down the whole Nook. I rebooted and tried again and that time it was ok. Then I installed YouTube app. As soon as I started playing a video, I got the same thing, where the Nook shut down instantly. I rebooted and tried it again. This time the video played, but about 5 minutes into it, the Nook shut down again.
I'm going to try to turn the volume down to see if that makes any difference.
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.
