leapinlar: Ask the question on the forum. I don't like using PMs.
Recently the update allowing google play store somehow bypassed the anti-update thing on my nook, so now I can use play store on the nook home, but the update removed my root but kept the android system home.. It uses a lot of ram, which i'd rather have free to play games or other resource heavy apps on.
I know I have to get my nook to start unsuccessfully 8 times, but I don't know how I go about doing that, can I get some help?

If you want to do it the easy way, just interrupt the boot by turning it completely off (hold power button for a few seconds) while booting eight times in a row. It will take you back to some version of stock, usually 2.0.0 or 2.0.4 then upgrade again to 2.1.0 when you register again.

After my HD+ locked up when I created a "Guest" ("child") profile and I had to do the 8-reboot process, after upgrading to B&N v2.1.0, I experimented with alternate button combinations at power-on. If I held the "n" button when pressing "power", I got a prompt that allowed me to do a factory reset.
Whether that is part of a later B&N recovery module, I can't say.

That factory reset just wipes data, it does not reinstall the ROM. He probably needs to reinstall the ROM since some of the broken symlinks may still be in /system.
Power + n takes you to stock recovery, which, without other parameters being passed to it, asks if you want to factory reset.

Thanks for the help!
I'd like to return my Nook HD+ to stock, too. It has a Cyanogen mod that precedes that startup, and I think that's getting in the way of the 'eight reset' mechanism for a total factory reset to stock software.
Is there a bootloader, system, and gapps zip that I could just flash from an external SD card that would do the job? Seems like there was, at one time, but it's getting very difficult to find them. Any ideas for a quick factory reset (not a wipe, but a complete reset to original OS?).

Go to my HD/HD+ CWM thread linked in my signature and flash the plain stock zip from item 6 there and follow that with a factory reset by CWM.
And it was not the cyanoboot that prevents the 8 reset, it is because when you originally installed CM you also replaced the stock recovery on internal memory with CWM. Stock recovery is needed for the 8 reset to work.

Thanks, that worked. I also tried the rooted version of stock, but it has a problem: "Unfortunately, Home has Stopped". Is there a workaround to this?

Don't use that version, I should remove it. If you want to root, do it per the thread with universal root rev 3.

Hi there,
I have a device that is also candidate for unrooting to stock. The thing is that I have tried both CWM and TWRP on bootable SD to try and fix the situation tith the apropriate zips but unfortunately none of them can mount sd ot any internal memory for me to reset.
Maybe I should also add that the device is charging without turning on except if there is a proper bootable sd inserted.
I presume a rescue bootable SD of OEM type could bring the device back to life.
I`ll apreciate any help.

When you say a candidate for stock, why? Is there something else wrong with it? I am just trying to see if it is bricked.

Maybe Bricked is the situation. The device is charging (the green light is present when plugged to the charger or USB ) but the power button can no longer start any visible boot process on the screen.
The story of the device is nearly the following:
I was using the device for a long time rooted with installed CM updating even with over night builds from time to time.
Once I had a problem booting properly after update but easily booted to TWRP and restored the previouse update.
A week ago the same situation occured, after an update procedure I left the device plugged to the wall charger and on the morning it was stuck on the CYANOGEN universal boot logo. No way found to boot to recovery found.
I figured the recovery has gone bad. Started to prepare bootable SD to try and fox the mess somehow, but could not do the corect procedure of preparing a good bootable SD many times. The only time I successfuly booted CWM recovery from SD I tried to install a zip with CWM recovery and as far as I remember at that time the bootable recovery was able to mount another SD wile it was booted on the device and the zip installed with success according to the software. Sadly after a restart the device was as is, stuck on the bootloader logo.
After 2-3 times successfuly booting both CWM and TWRP recoveries from prepared SD card, doing nothing at all that can alter the device, just tried to see how to mount any usable memory, the device stopped visualy booting without an SD.
Thank you for the reply, hope you can add some wisdome to the happy end

It sounds like it is bricked. If recovery said it installed successfully and it still will not boot normally, it is usually what that means. By bricking, I mean internal memory has become read only and nothing can successfully be written to it even if it said it was successful. Your probable only option is to use a noemmc version of SD CM. Search the dev forum for that term.

No, it is probably from running CM11. That has a history of bricking devices with the faulty emmc chip due to applying trim automatically.

Hi there,
I have used the forum in the past to successfully install custom roms on different phones. However, this gave me a false sense of my technical ability (which is low) leading to my current predicament. I bought a nook hd plus a couple of months and followed the post on how to install cwm 10.1. I followed the instructions exactly, but my nook kept looping on the boot screen. I tried again several times, but to no avail. I've now learnt my lesson and just want to restore to its original state, but now I have two problems:
1. I don't know how to do this.
2. My dad has misplaced the sd card I used to install cwm on, and because the tablet has been completely wiped, it won't start at all. I have ordered another sd card, but I'd be really grateful if someone could provide or direct me to an idiot proof guide on how I restore my tablet.
Thank you in advance,

First you need to get your new SD. Then you need to make a CWM SD per the instructions in item 1a in my HD/HD+ CWM thread linked in my signature. Then go to item 6 and flash a plain stock zip I have there.
And how did you completely wipe the tablet if you don't have a CWM SD?

I probably didn't explain it properly, with regards to wiping it. When I tried to put the custom rom on it, the instructions required me to wipe the stock rom, and now that I don't have the micro-sd card it won't boot. I have no idea if that makes sense or not :s. #noobfail
You did not wipe the ROM. You wiped the data.
Try booting and holding the power key and the n key for a few seconds. Release the power key before it turns itself off. It shoud boot to recovery. If you installed CWM or TWRP to internal memory, it should boot to one of them. If it boots to a screen that says 'do you want to erase?' then you have stock recovery still on.
If you have stock recovery, it should reset itself to pure stock after you interrupt the boot 8 times in a row.

I purchased a Nook HD+ (16GB) for a great deal. It was rooted when I purchased it. But I wanted to restore it back to like if I just bought it from the store. It is going to be a gift for someone. Is there a tutorial or step by step for this?
Model Number : BN NookHD+
Cynagenmod Version: 10.2-20131119-Nightly-vation
Build Number: cm_ovation-userdebug 4.3.1 JLS36I
Please Help!
I also currently don't have an SD CARD. It looks like whoever rooted it just did everything on the main storage and not a SD
If you still have stock recovery on internal memory, you can do an 8 failed boot reset to take it back to stock. To do that, interrupt the boot 8 times in a row by hard powering off (hold power key for several seconds) as it boots. On the 9th boot let it continue and it should boot to stock recovery and reset itself. If it boots to CWM or TWRP recovery instead, you can use that to flash my plain stock zip from my HD/HD+ CWM thread linked in my signature and item 6 there.

Try getting into CWM by booting holding the power and n keys together for a few seconds, releasing the power button first followed by the n key. That should get you into the new CWM on internal memory. Then you can use that to factory reset to start CM11 fresh.
If that does not work, go to my HD/HD+ CWM thread and make a new bootable CWM SD. Use that to flash a plain stock zip from item 6 of that thread followed by a factory reset with CWM. That lets you start over like it came out of the box.
The 8 failed boot procedure did not work because you had replaced the stock recovery with CWM.

Try using a different SD card if you can.
From what I've read, a 4GB Class4 card is the best. My 16GB will boot less than 1 in 20 times, but my 4GB boots 9 out of 10 times. Also, make sure you have marked the microSD partition as Active using a partition tool.
Fwiw, I got a class 4 sandisk 8gb card. Total noob to android. Booted first time and every time since. Only trouble I had was with win32diskimager. Not only did it not work, it hosed my windows 7 install. I used a program called sdimager instead.

I thought wtf did win32diskimager do that? Hard to believe. So I downloaded it again from sourceforge, scanned it with avast and malwarebytes, ran it again, same thing happened. OK, better find something else.

I had the same issue today, just put cm11 on it and it worked fine, during charging it changed to cyanoboot loading image and it just stuck there. I can not boot to CMW.
any luck? did you recover yours?
Also stuck on cyanoboot screen
Hi all, very similar situation - my Nook HD+ is completely bricked too.
Been a happy user of CM11 on Nook HD+ for about 4 months. I used the guide here to install it.
http://forum.xda-developers.com/showthread.php?t=2602796
Then one morning it would not boot - only showing "Nook" screen when powered up. I tried to reinstall CM11 but with no luck.
I created a bootable SD card with emmc-cwm-early3.img using dd command (dd if=img file of=/dev/sdc bs=1MB). When inserted, Nook would power up and go to Cyanoboot screen and but it would hang there
I went through 3 different SD cards (all type 4) and they are all same
I One interesting thing - I found sdcard-cwm-early9.img from http://forum.xda-developers.com/showthread.php?t=2600572. When I create SD card from it, it actually boots up to CWM screen, and it lets me go through various backup/restore options. However, the image only creates about 120MB of free space in SD card and I cannot place any zip files in it.
The reason for bringing out the last point is that it does seem that my Nook HD+ would boot up from SD card, but not with emmc-cmw-early3.img.
Any pointers would be greatly appreciated. Thanks so much.
- Dan
I'm having a very similar problem to yours suite800, only I was running rooted stock when it happened. Same thing though, normal boot freezes at the first Nook screen.
I've tried a number of different bootable SD images on a few different cards and all of them freeze on a screen with only the cyanoboot logo visible, with the exception of sdcard-cwm-early9.img. That image gets me to a cyanoboot menu but I can't do anything from there, if I select "Boot CWM Recovery" it just hangs on the cyanoboot screen with a message "Loading recovery from SD..."
I accidentally completely wiped my Nook in recovery without installing any other rom, because cm 11 had a problem installing. And then I turned it off. It doesn't seem to turn on at all. However, I can connect it to my PC and it reads the OMAP4770. Any way I can bring this tablet back? Or is it gone?
Also, I have tried every reset option I've seen online, like power and/or home button for amounts of time. I believe that since I lost the system files it won't start up.
Why don't you just follow the instructions here http://forum.xda-developers.com/showthread.php?t=2317500 and make yourself a sd recovery and take it from there?
Don't worry you are not lost
It won't boot at all, let alone into recovery. Of course I did try to boot into recovery since that's what I used to wipe it. Did not work.
I completely erased everything in the tablet's memory, including /system. I could be wrong but I think that's why it won't show up with anything when it turns on. No light or logo.

OK just tried different Bootable with CWM instead of TWRP and it booted up to it.
Thanks for the help people.
Now I'm still having issues with flashing CM 11 on it. Status 7 error.
I think that's because I don't have stock installed right?
Anyone know of a CM 11 zip for HD Plus that won't check for stock first?

No, that status 7 error is because CM11 needs version 6045 or newer CWM. Go to the dummies thread linked in my signature and follow post 7 there.
