Your PC should use the same MTP driver for CM10.2 and stock. Do you have the MTP settings right in CM10.2? I think it is in storage/menu/USB computer connection. At least it is in CM10.1.
[Nook HD, HD+ General] b_rangel29:
nook hd

Yes, I have my setting checked for an MTP device, also tried to check PTP just to see if pc recognizes; to no avail. Using same cord, USB port, etc.... Also went into device manager to update drivers and my nook is showing up there with the yellow caution symbols, but can not find any driver updates.... Next step, maybe reboot and plug in again????? Idk...
[Nook HD, HD+ General] leapinlar:
I know what is wrong. You have to turn off Android debugging in development settings.

If you don't know how to get to development settings, go to Q5 in the FAQ post in this thread.
[Nook HD, HD+ General] b_rangel29:
I've tried that as well. I found another forum where you talked about cm changing drive numbers and all the links to b&n to install those drivers, I just wasn't sure if that was something I had to do... It was extra annoying doing so for my phone.
[Nook HD, HD+ General] leapinlar:
That was for setting ADB drivers. If you turn off Android debugging and reboot and connect the cable, the standard MTP device should install. Also try removing that MTP driver in windows that failed before turning off the debugging. It is not really the MTP driver, it is the ADB driver trying to install because you had debugging on.
[Nook HD, HD+ General] b_rangel29:
nook hd

Ok, I tried all these actions and pc is still showing device in device manager as MTP with the yellow caution symbol. And when i turn on debugging it will show up as nook hd w the caution symbol. Actually its not showing up at all as Nook HD anymore after uninstalling the drivers. Just as MTP w caution symbol.
[Nook HD, HD+ General] leapinlar:
If you have Android debugging truly off, those drivers should not show. Do those drivers disappear when you unplug the cable? They should. Of course you are using windows 8.1 which I know nothing about.
[Nook HD, HD+ General] b_rangel29:
nook hd

I believe usb debugging is truly off. Settings>Developer Options>USB Debugging. That is the only way i know to turn it off or on.... Is there an advanced way to turn it off or on? The driver does disappear when i unplug the device, then reappears when i plug it back in(with the caution symbol). Fyi: Before and after root the nook was detected, after cm/gapps install it was no longer detected.
[Nook HD, HD+ General] leapinlar:
I run CM10.1.3 stable and the option is Settings>Developer Options>Android Debugging, not USB Debugging. What version of CM10.2 are you running? You might try the 1/18 verygreen unofficial version in his CM10.2 thread. Here:

forgot something

I'm running cm 10.2-20131102-snapshot-m1-hummingbird. Yes, in my version of cm its under usb debugging. To run that verygreen version do i need to wipe all my data or just flash that rom? Also all i see on your link is an emmc install, seeing as my computer cant find my device, wouldn't i need an sd card build? That way i can just copy the zip to my sd card and install from there. Or can I install an emmc file to my sd card? Sorry, I am new to this and I'm just trying to learn all this the best i can.
[Nook HD, HD+ General] leapinlar:
You have the MTP driver successfully installed as evident by it working on stock. The issue is your PC is detecting that Android debugging is on and therefore searches for ADB drivers. And that initially shows up as an MTP with an exclamation point. It is not MTP, but the ADB driver. That interferes with the real MTP driver that is really already installed. I have found in the past that when the ADB driver is finally properly installed, the real MTP driver takes over and works, even if debugging is on.

Edit: just flash the ROM.

Edit2: But if it still does not work, try the factory reset in CWM since the debugging is a setting and may need clearing to make it turn off.
[Nook HD, HD+ General] b_rangel29:
nook hd

Flashed the rom and device isnt showing up at all now.....:mad: So i guess I will factory reset n flash again???
[Nook HD, HD+ General] leapinlar:
No need to flash again, just factory reset.

Cool. Thank you very much for helping out btw.

Well the factory reset got my pc to recognize the device in the device manager w caution label(BN Nook HD), but still saying doesnt have drivers. USB debugging is off, checked as MTP device...8.1 is really starting to get annoying....
[Nook HD, HD+ General] leapinlar:
I don't know enough about MTP on Windows 8.1 to help. You might try doing a Google search on MTP, android and Windows 8.1 to see what you get.

Since installing cm on my nook, I've been having problems with internet browsers crashing, tried several different browsers but all do the same thing, what could be causing this?
[Nook HD, HD+ General] leapinlar:
I don't know which version of CM you are running, but I suggest you post that question in either the CM10.1 or CM10.2 thread.
[Nook HD, HD+ General] aquaminh:
This post is absolutely essential to noobies. However, can you do some tutorial on the basics of Android rooting and flashing? The meaning of the terms, location of the trusted sources, for example.
[Nook HD, HD+ General] leapinlar:
Did you read the FAQ in the third post? It was also written by e.mote and answers many of your questions.
[Nook HD, HD+ General] aquaminh:
The 3rd post is so helpful but there's no mentions about what is kernel and how to mod/change/control it. Can you add this?
[Nook HD, HD+ General] bblubb:
Hi!,

Thanks for this very helpfull guide!

I've ordered a Nook HD+ which should arrive any day now. In the meantime, I've browsed the forum, also especially this thread, and prepared everything to install CM10.2. (I've rooted and flashed a custom ROM on my smartphone last year and the procedure is almost the same, but still, it was really necessary to read everything!)

However, before replacing the ROM on my new Nook HD+, I've still got 2 questions:

1) does the CM10.2 zip-file also contain a full new Kernel, including the necessary patches concerning the 'TRIM'-issue, or do I need to search for the optimized kernel somewhere else on XDA if I don't want to see the tablet slow down over time?

2) just to be sure: I'm mainly interested in a stable, efficient and performant ROM (not that much in the latest UI or graphical-effects etc.) Is it correct that CM10.2 is better than the stock ROM? (I guess CM11 should be better considering the improvements on the RAM-usage in Kitkat, but I'd rather wait for the official, stable version CM11 release rather than a nightly, and thus use CM10.2 if it is worth it.)
[Nook HD, HD+ General] leapinlar:
I believe the CM10.2.1 stable that is now on the CM site includes the kernel that has the TRIM fix, but don't know for sure. You had best ask that on the CM10.2 thread in development.

CM in general is better than stock. I don't know about CM10.2.1 since I run CM10.1.3 stable. Again the folks over at the CM10.2 thread might have a better handle on that. This is just a guide on how to install, performance questions should be asked there.
[Nook HD, HD+ General] mamalone:
I've been experiencing an issue where apps will suddenly, continuously, and frequently stop and restart. The two apps that I notice (but I'm certain it happens to other apps) is Talkatone ("Talkatone has stopped" and "Talkatone has started" in the notification bar every minute) and EasyEyez (flips the screen temperature nearly as frequently). I've deleted almost all non-essential apps to try to determine the issue, but nothing has worked. Has anyone experienced an issue like this?
[Nook HD, HD+ General] bblubb:
Thanks!

I've posted the questions in that thread as you recommended.

It's probably a noob-way of thinking, but as CM10.2.1 is posted as 'stable' on the CM-website, I guess there is no (significant) reason not to go to that version directly if I'm installing a new ROM anyway. I'm very curious of what it will be like.
[Nook HD, HD+ General] leapinlar:
You have not said what version of CM you are running. In any case, this thread is for installation issues, not operating issues. I suggest you ask your question either in the CM10.1 or CM10.2 thread.

problem

When trying to make the bootable sd card im getting the following error, Error 23: Data error (cylic redundancy check). It is a scandisk 4 gb class 4. I formated it to fat 32 using sd formatter as windows wouldn't do it. Any advice would be awsome as i hate the stock nook os.
[Nook HD, HD+ General] leapinlar:
What are you doing when you get that error? Burning with win32diskimager or copying the boot files?

That fact that Windows would not format it says to me you have a bad card. That error sounds like a bad card too. And you probably did a quick format with SDFormatter which is not a true format.
[Nook HD, HD+ General] Fox204:
The error is when I'm trying to write the boot files. I have gotten it to work once with the smaller file. When using SD formatter I'm using the full wipe. Windows will format it to fat or exfat.
[Nook HD, HD+ General] leapinlar:
I still suspect a bad SD. I have never had a user report that error before.
[Nook HD, HD+ General] micallen:
If I already have CMR installed and 10.1 installed, and want to go to 10.2 Can I skip a step or two??
[Nook HD, HD+ General] leapinlar:
Yes. But if the CM10.2 acts up after flashing without wiping first, go back to CWM and factory reset to start clean with CM10.2.
[Nook HD, HD+ General] K.M.J:
Hello! I have spent some time wading through searching the Nook HD/HD+ forums for a solution to a /data restore error. I deemed this thread more suited to my query as I am brand new to both Nook & Android, qualified dummie!

I was able to follow leapinlar's SD card instructions for CWM to create a proper backup via "CWM flashable zips" thread (thank you!) & I used the new procedure without a hitch. I didn't have very much on it yet since I unwrapped it today, but since I was going to be attempting something new, I wanted to have an "undo" out!

My goal was to copy a saved gamed (.dat file). I had loaded the game app via the play store & was surprised to see the game started me over instead of syncing with my account. Prior to I had assumed my game save was on the game's server, not a save to device. A friend managed to get into my previous tablet's data & emailed me my .dat file I would need. I did a search of my backup data .tar file and located the .dat file to replace. Then I made a second copy of my backup & replaced the .dat file. Swapped my original backup on my SD to this edited copy.

Trouble came along when I booted up CWM on my Nook to copy the restore /data via the advanced restore option. I had to clear my MD5 file in order to bypass a "mismatch" but then received a "Error while restoring /data!" after it had started the restore. I attempted this 6-7 times, experimented w/a couple SD cards, & using the full restore option instead of advanced. All the other options of restore /system, /cache, etc. work without errors as does the original unedited backup. I am baffled as how to continue, any advice would be appreciated!

[Nook HD, HD+ General] leapinlar:
Do not put that dat file in your backup. Even though you deleted the md5 file it still could be corrupt by messing with it.

Your best solution is to put the dat file directly on your device with a file manager. I assume you are running CM instead of stock. You do not say. Just boot up to CM and using your file manager put the dat file in the appropriate place in sdcard. You will know where by where you put it in the backup (/media equals /sdcard). Even if you are running stock you can do it the same way.
[Nook HD, HD+ General] K.M.J:
Eep, sorry, missed that part of my post, I was stock. Now I am rooted stock.

Did I mention how ridiculously new I was? I hadn't even tried using a file manager! Thank you for helping me remember the most obvious & easiest fix can be the solution. File was moved successfully! Thank you again!
[Nook HD, HD+ General] mug2k:
I just made a mistake. I installed CM11 and GAPPS but forgot to do CWM first. I am still in recovery, should I wipe/factory reset first and then reinstall everything in the correct order?
[Nook HD, HD+ General] leapinlar:
This thread is for CM10.1/CM10.2, not CM11. The tools here do not work on CM11. But if you are saying you forgot to backup stock before you installed CM11, it is too late, it is already gone.
[Nook HD, HD+ General] mug2k:
No I backed up the system first but I didn't install the cwm-recovery-ovation-6, so just wandering if its ok to wipe/factory reset again and reinstall the items below in the correct order.

Huge thank yous to e.mote, leapinlar, verygreeen, and anyone else involved in making this possible. Backup and installation was done in less then 20 minutes. The only way this could have been easier would be for you to have come to my house and done it for me. :good:

So I installed CM on a new Nook HD+, and it worked great for about 24 hours. Now everything is absolutely creeping slow, and the device shuts off seemingly randomly. I can reproduce the shutoff when I try to load a youtube video in chrome, but that isn't the only case where it will happen. I tried clearing the cache and the dalvik cache, but that didn't help.

Anyone have any ideas?

Is it too much to ask for a Dummies Guide to go back to Nook Stock ROM in case one had to?

OK, finally jumped to CM from stock yesterday following all the procedures here.

One question during the back up though, I used a 4G card and after I wrote the image into it, it only has the capacity of 900 mb (like a dvd?), the rest 3Gb became unallocated if checking it with the partition tool.

Since I have used the nook hd+ in stock for a month or two, the backup file exceeding the card capacity (only 850Mb free, 50Mb used for the bootable files and stuff in the image). I had to back up to the internal SD of Nook HD instead of the "external SD" otherwise error during the process.

So I guess in the OP, we should make some changes:

in the backup process, if you have a clean stock rom, I guess you can "back up to external SD" meaning your bootable microSD card. And then the card can stay as a permanent rescue card to go back to stock.

Otherwise, you will need to "back up to SD", then the backfiles goes to Internal SD of your Nook HD+ and you want to copy it out somewhere in your PC in case later on you wiped the internal SD for other purposes.
[Nook HD, HD+ General] leapinlar:
You must have used the "small" image instead of the 4GB image. Otherwise the full 4GB would have been allocated to the SD.
[Nook HD, HD+ General] procter:
Can you point me a link to the 4gb image? Is this the one "NookHDplus-bootable-CWM-6028-for-stock-4GB-rev4-(05.15.13).zip (9.36 MB, 28043 views)"?

I downloaded the one from this thread: http://xdaforums.com/showthread.php?t=2602796. Strangely, it doesn't match with the "smaller version" mentioned in your thread. This one is 7.2MB vs 5.8mb (small version).

Then you installed kitkat (CM11). This thread is for CM10.1/CM10.2. The files here do not work on kitkat.
[Nook HD, HD+ General] procter:
Sorry I did not mention this, yes, I installed CM11. I thought the bootable SD image works universally? As far as I understand, we are just using it to boot to CW recovery and flash the emmc version of recovery, ROM and Gapps.
[Nook HD, HD+ General] leapinlar:
It is not universal. CM11 requires its own version. That is why I say at the top of my post not to use these files for CM11. And do not use the CM11 CWM files on CM10.1/CM10.2. They will give you error messages if you try to use the wrong CWM.
