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.

Hello folks. I got a Nook HD+ a few days ago. Made a CWM sd card and flashed emmc CWM. For some reason it didn't take. When I would reboot the stock recovery would still be there and the cyanoboot logo would not show.
I tried booting from a SD boot image and then using the newer method from a SD with only one fat32 partition with the boot files unzipped/unrared into it. It would boot into CWM fine from SD but would not flash into emmc.
After trying a bunch of other times I finally got emmc to flash. I think. The reason I say I think is because even though I would now see the cyanoboot logo but it wouldn't go past that.
I tried flashing back the stock recovery. Nothing. It wont stick. I'm not sure how to get into CWM if it really is in emmc. I also tried to flash CM but it will not flash either.
Please advise how I should progress from here.

How are you knowing it is not sticking? Are you trying to boot to emmc CWM by using the key combination? Hold power and n simultaneously when booting for a few seconds, releasing power first before it turns itself off, followed by the n key. It should boot to whichever recovery you have installed.

I'm turning the device on. I've tried holding the on and the n button while the nook logo is on the screen and when that didn't work once I see the cyanoboot logo on the screen. Both times of hold the power and the n button for roughly 7 seconds and then let go of the power button and then the n button. I've been asked if I want to test the nook to factory and haven't seen any other kind of menu. Certainly not CWM.

I would suggest re-downloading the cwm file from the site to make sure you don't have a corrupted file.

I did the power/home key combo and no results. I'm crushed. I don't know how to fix it. I have a $200 paperweight atm. :crying:

You said you got it to boot to a bootable CWM SD. If you can still do that, go to my HD/HD+ CWM thread and flash a plain stock zip from item 6 there followed by a factory reset with CWM.

Hey Basilla as someone trying to balance whether to root/install cyanogen, did you have positive results restoring to stock? Hope you did. Cheers.
It was quite easy AFTER if got the darn thing to boot into recovery mode. First I got it into recovery & immediately
installed the last stable version of CM. Then I rolled the stock ROM. After I registered my device etc again in went ahead & rooted it and put the stable CM 10 back on my device. East peasy, took about 15 minutes total after it booted to recovery mode. Will not update again until another stable version is released.

Thanks
Hey Basilla, thanks for the info on your success. Have a great day and I'm glad you got it working!
