Hi There
I got my Nook HD+ a couple of months ago, and I've started noticing quite a bit of slowdown in Apps, in particular getting a lot of "xxx isn't responding, do you want to close it - Wait/OK messages.
I've installed various tools to monitor CPU/memory etc but not been able to. Running Cleanmaster to clear memory and caches sometimes seems to give some brief respte, but not for long> I also used Malwarebytes AV and found a trojan dialler, and removal of that againseemed to help for a little while, but the problems came back a few hours later.
I therefore decided to give the CM ROM a try and installed 10.1, and which I really like the interface and woul dlike to carrry on using it, it would seem that the problem is even worse on this version of Android. The basic laucher itself isn't too bad, but applications are barely usable, which initially made me wonder if I've got a hardware problem.
I'm using a Kingston 8GB memory card (I did read somewhere that somebody else had problems with speed on a similar SD card, but as far as I'm aware Kingston should be a decent brand)
I've been reading through the forums about the trim issue, and it would appear I have the MAGDA eMMC which is suseptible to the trim bug, here are the details on my version:
$ su
# cd /sys/class/block/mmcblk0/device
# cat name
MAG2GA
# cat manfid
0x000015
# cut -b 19,20 cid
6
# cat date
10/2012
There seems to be a fair amount of debate about wwhether it's safe to try the fstrim fix along with 10.2 on this version of the chip. I'm also wondering if pulling the SD card and trying a hard reset might be worth trying.
Would anybody be able to to offer me some guidance on whether this is likely to be the trim issue, and whether I'm safe to try fstrim/Lagfix?
I have tried to read up as much as I can before posting, but there's a lot of information and I'm not entirely sure how much of it is currently in date, so I'm still not entirely certain whether this is what's affecting me, and what the best course of action from here is. Apologies in advance therefore if this has been covered elsewhere.
Thanks very much in advance.
Alex.
It does sound like you are experiencing LAG and are in need of trim. But you have the buggy emmc chip and I would not recommend it. Try booting to your CWM SD and going to mounts and storage and format 'data and datamedia'. See if that helps. An ordinary factory reset does not really format /data and will not make it better. That is why you still had LAG after installing CM10.1.

Thanks very much for the reply.
I've booted back into CWM, and the Mounts and Storage menu gives me the option of mounting or formatting several partitions:
/sytem
/cache
/emmc
/data
/sdcard
There doesn't look to be an option for "Format data and datamedia" however (I get the impression this should be a distinct option?).
I tried formatting just /data, after doing so and booting back into CM it started to run through the initial setup. The CWM version I'm using is v6.0.3.2.
A bit of further googling suggests that /data/media is hosted on /sdcard, but if I navigate through the filesystem it looks like my personal data from the stock install is /emmc, but I'm a bit wary of formatting this in case it affects the stock ROM. Coudl this be what I should be formatting instead?

Are you running CM10.1 on SD? I thought you replaced stock with CM10.1 on emmc. That was my basis for saying you need to format 'data and datamedia'. It uses the same /data that stock used, thus carrying over the LAG problem. An SD install puts /data on the SD (unless you used the hybrid SD install which then does use the same /data partition on emmc).
And I am not talking about /data/media. I am talking about 'data and datamedia'. That option actually formats all of /data including /data/media. A format /data with CWM does not "format" anything. It erases all of /data except /data/media, leaving your media files intact. An actual format is necessary to remove LAG.

Leap,
Thanks for this! I did format 'data and datamedia' and this fixed the lag I have been experiencing. I had to register w/CM and it reloaded some apps from Google play and I had to re-install other apps using Apps Back-up and Restore. Not ideal having re-install periodically (monthly?) in order to keep it running smoothly.
This proves to me that these tablets need TRIM. However, I have an HD+ 16GB with MAG2GA Date:11/2012, FwRev 0x06. Do you think it would be safe to try KitKat on SDcard or would that still subject my Nook to bricking?
BTW, Bought this on the Mother's Day deal so, still under warranty
Thank again,

Understood. When I couldn't find the "data and datamedia" option on CWM I did some googling, and "/data/media" returned a lot of hits, it seemed like a plausible alternative.

That is why you did not find that option. You need to use the CWM made for stock from my HD/HD+ CWM thread.
And the lag when running from SD is likely caused by the brand and class of your SD. It needs to be a SanDisk class 4.

To get around having to re-register and re-install everything, do a nandroid backup with CWM and after the format 'data and datamedia', do a CWM restore. That will put everything back but your media files. To save them, back them up manually to your SD or PC and manually restore them later. I know this is a pain to do but it is better than bricking your device.
And I don't know anything about kitkat on SD and trim. Even on SD some things are on emmc.

Right, understood. Sorry, when I made the original post I think I don't think I fully understood the purpose of the eMMC chip, obviously if it's running on a separate filesystem can't be the same problem. I've now got a Sandisk card on order, will give that a try next and go from there.
Thanks for your help, appreciated

Hello XDA community let me start by saying thank you for sharing all this great info. I finally made the decision to install over my B&N HD OS and go full Droid using cm-10.1-20130615-UNOFFICIAL-hummingbird-emmc. Its running like a damn beast BUT one little thing is irking me. Whenever I download an app/game EVERYTHING seems to go to the internal memory and not my freakin' empty 32gb micro sd :good:. Furthermore, I don't even see the option in apps to "move to sd". How can I remedy this issue?
P.S- Yes the Sd card is formatted correctly and can be seen in storage.
Thanks in advance for any help!

Apps2Sd is not supported in CM10.1.
And verygreen has the emmc version of CM10.1 set to use internal memory by default and there is no setting to change that. But I have developed a flashable zip that will swap internal and external SD's so that the default goes to external. See my HD/HD+ CWM thread linked in my signature and look at item 4.

Is this fairly reliable ? I purchased a 32GB model, thinking I would need it but, after 2 weeks I am hardly using any space. Perhaps I should return and get a 16GB model instead...

I don't get any reboots, but many users do. I think it depends on what apps you have installed and which run in the background that might be causing the crash and reboot.

Hey Leapinlar I tried your advice and I'm not getting any results. Here is exactly what I did.
1. Boot into CWM wiped the system and cache
2. installed cm-10.1-20130624-UNOFFICIAL-hummingbird-emmc
3. installed NookHD-HDplus-SDSwap-for-verygreen-CM10.1-on-emmc-rev2-(06.16.13).zip
4. Boot into cm-10 went into settings then storage (Verified MicroSD is detected 29gb)
5. Installed HD Widgets and it automatically goes to the Internal Storage
Am I doing something wrong? Please tell me I am lol...
I also do a reboot and try again but no luck. Any other advice? Maybe something I can do manually?

The swap does not effect where things get installed. They will always get installed to internal memory. The swap only effects where apps download and save their media files.
If you are running out of room to install apps, delete or move some of the media files from internal memory. App installation files and internally stored media files share the same free space. If you get rid of some internal media files, more apps can be installed.

Hello,
First off, thanks to e.mote for the CyanogenMod 10.1 for Dummies guide and to the work put in by verygreen, leapinlar and bokbokan. The guide was simple and straightforward, I installed CM10.1 and CWM (seemingly) without a hitch.
However, when attempting to do a baseline backup, I'm running into some problems. I've searched the forum overall and gone through pages and pages in the Nook sections and not found any real solution. On my 8GB HD, when rebooting to recovery and attempting to backup to an SD card, I'm having the following issues:
When CWM loads, I get a "warning: no file_contexts" message. I've read mixed things about whether this is significant or not and what to do to correct it.
When I go to backup and restore>backup it seems to backup to the SD card without a hitch (although it has shown differing amounts of free space on the cards whenever I've attempted this). But when I insert the card into my computer to copy the backup, the only thing on the card is a folder called "LOST.DIR" and all the space but 3.1MB is free. I've done this 3-4 times so far, with two different microSD cards (one 4GB, one 32GB). I've both checked it and formatted the card (in FAT32) on a computer running Windows XP and one running OSX. Same results on both every time.
At some point when attempting to do the backup, the screen of the Nook begins to flash/flicker and doesn't stop until I restart it.
The first time I tried to do the backup, after I tried to restart, it didn't boot back up and the power button was unresponsive. Possibly this was due to overheating? I plugged it into the charger and it started up on its own after about 10 minutes.
Anyone else encounter this? Any solutions. Obviously I want to be able to back things up. I just rooted the device this evening, so I'd rather to not have to go through the install process all over again rather than have a proper backup.
Thanks!
You need to tell us which version of CWM you are running. And is installed to internal memory or SD?

Ah, ok. That means you have the newest version which puts the backup on internal memory. If you look at the menu choices closely, you will see it says to internal sdcard and the other choice is to external sdcard. So you will not find the backup on your external card.

Thanks! That'll teach me to just blindly follow instructions rather than looking around and exploring on my own - I didn't even notice the "Backup to External SD" option. So, thanks for your patience, your work on this and your speedy replies. Seems like all is well now.
Hoping that someone might be able to give me some insight and/or direction.
I've been running CM 10.2 off EMMC for a while now. I started having some issues with slowness and I was interested in CM 11, so I put CM 11 on an SD card so I could dual boot. CM 11 ran well. CM continued to run worse and worse. Bluetooth would timeout, web browser was extremely slow...it was pretty unbearable.
CM 11 ran like a dream so I decided to put CM 11 on EMMC. After I did so, it ran just like 10.2 did. It took 10 - 20 minutes just to get through setup. Gmail would timeout (and reboot) when it tried to sign-in. Apps wouldn't load. I would click on buttons and it would take 1 -2 minutes for the the NOOK to respond.
When I put CM 11 on, I did a factory reset (a couple of times).
So, I decided to put stock back in...without CWM...pure stock. Well, it is still slow. Booting from SD card runs fine.
Any ideas what could be wrong? I'm running pure stock now, so I could take it to B&N, but I don't remember when I purchased it. I'm not sure they would do anything.
I appreciate any suggestions. Thanks!
Yes, you are suffering from LAG and need to run TRIM to fix it. But be careful as these devices with certain internal chips can be bricked running TRIM.

Thanks. I was running CM 10.2 with the trim-enabled kernel. Also, I had completely wiped /data and all the caches.
I noticed in settings (which took forever to load) it said I had used about 10 gigs or so...which I thought shouldn't be the case if I had formated /data and did a factory reset from CWM. I did a hard reset with factory restore and now things are moving along well.
Do you still think it was the LAG issue? I thought that formatting /data and /cache would fix the LAG (also I thought running the trim-Kernel would fix it too. Perhaps TRIM didn't have a chance to run because I've been dual booting? Although the reason I went to the dual boot was because of the slow issue.
I don't know...perhaps I reflashed a 10.2 ROM and forgot to flash the Kernel, but I've been on the same 10.2 rom for a while.
Either way...things seem to be working now...but now I have to start from scratch to get CM 11 on EMMC.
Thanks for the response!

There's a thread over in Android Development that discusses the TRIM related issues. It seems the only chip effective is rev. 5 (if I remember). I believe I have the rev. 6 and have been running the trim enabled kernel since last October or November. Sorry my memory is so faulty. If you need me to, I'll find my chip again (have to wade through the very long 10.2 thread to see what the command is since I've forgotten).
Some people say it is safe to do. I have tried it myself with no issues. You have to ask yourself if your device gets bricked can you afford to replace it? If no don't do it.

Your issue was you did not really FORMAT /data with those CWM commands. Because the HD/HD+ uses an emulated internal sdcard (/data/media), it only ERASES part of /data keeping the media files intact. So all of your earlier media files remained even after CWM /data format and factory reset commands. The only way to really format /data is to go to mounts and storage in CWM and format 'data and datamedia'. Then it really FORMATS all of /data (including your media files in /data/media) and gets rid of lag. Of course your hard reset and factory restore did that too.

Okay. That makes sense, although I wasn't aware of that behavior. Guess running TRIM manually would have fixed my issue. It took a while, but I have CM 11 running now. Thanks for all your work on that. It seems much faster than 10.2.
I have an issue that seems to be similar to those suffered by a number of people. I'm just having difficulty understanding the cause of it, and the solution. I have a nook hd+ that no longer boots as a result of trying CM11 on an SD card.
I installed CM11 to an SD card (as I was nervous of altering my nook) using bokbokan's excellent instructions. Initially it seemed fine but this morning it was unexpectedly out of battery and will no longer boot.
The symptoms are similar to this: http://forum.xda-developers.com/showthread.php?t=2611769, this: http://forum.xda-developers.com/showthread.php?t=2736347 and this: http://forum.xda-developers.com/showthread.php?t=2649061&page=2 except that the posters there had previously replaced the stock software and overwritten the emmc.
When the SD is in, it locks up on the Cyanoboot screen, when the SD card is out I only get to the black screen with 'Nook' on it and no further. It looks like the SD install has messed something up on the internal emmc. Hard resets and multiple failed boots don't appear to help.
I can occasionally (but not always) get it to reboot to CWM recovery by reinserting the card and holding down N and lock, but I get a lot of errors such as "E:Can't open /cache/recovery/last_log", "W:failed to mount /dev/block/platform/omap/omap_hsmmc.1/by-name/cache on /cache failed:No such file or directory" and "I:Can't partition non-vfat: /emmc (ext4)". When I go to 'Mounts and Storage' in CWM, I cannot mount anything (e.g. "Error mounting /boot!").
I chose to go down the SD card install route (using ) in order to avoid touching the stock install on the emmc, but now the whole thing is dead.
Reading other threads, it sounds like either:
1. The emmc is bricked due to some firmware bug. The impression I get from reading around is that CM11 was supposed to incorporate a workaround for the issue. If the emmc is the problem, I have to return the Nook and hope to get a working one.
2. The emmc has (somehow) become corrupted, I have to put a different version of CWM on my SDcard (so it will install to the EMMC rather than the SDcard, and because CM11 uses a different version), using the instructions here: http://forum.xda-developers.com/showthread.php?p=35811322 and then reinstall a stock rom to my emmc. I then have to reregister the Nook (not sure if this is essential) before being able to use my CM11 SDcard install again.
If it is the first problem, I would like to know how I can check to see if the emmc is indeed broken.
If it is the second, I would be grateful for any help in understanding how and why the SD install has messed up the emmc, and whether the steps above are likely to bring it back to life.
It sounds like your emmc is indeed bricked. I would go for the warranty exchange now. Just because you installed CM11 to SD does not mean it does not use emmc partitions. It still accesses and uses many of them (cache, rom, bootdata, /data/media, etc.). So there is opportunity for a brick. I would exchange it now while the cyanoboot logo does not show when booting without the SD.

Thanks to both for replying. I feared that was the case.
I'm a bit disappointed that the SD card install (generally the option for those who want to leave the nook untouched) can in fact ruin the machine.
I've contacted the Nook website and will see what happens.

I've contacted the Nook website and will see what happens.

Just take your device to a store. They will exchange on the spot once they verify your registration on their computer. Of course don't tell them you were running CM, even on SD.

Thanks, but there are no BN stores in the UK. They don't even sell the Nook directly from their uk website anymore. I have to post it to the Netherlands and see what happens.
So, after 2 months, and a lot of arguing with customer services, I have finally got a replacement Nook through the post.
I am still keen to try CM, but want to be really sure that my Nook doesn't get bricked again. Is there any way of checking whether an sd card install is likely to trigger an emmc failure on my new Nook?

The best way to avoid bricking by CM11 is to not try CM11. I run CM 10.1.3 and have heard of no one bricking when running that.

Hi all,
I've been running a Cyanogenmod nightly version since december. version 10.2.20131222.
My HD+ has the bad memory issue. What would you guys reckon I should upgrade to. Its starting to run slow and a factory reset seems to be a temporary fix.
I havent replaced the boot rom.
Cheers

What does that last statement mean? Are you saying you still have stock on internal memory and you are running CM from SD?

I haven't installed a recovery e.g. cwm.
Cheers
So what you are saying is you are running an early version of CM10.2 that does not have TRIM activated and you have started to get lag. You have the bad memory chip and are worried to run something newer with TRIM activated. So now you want advice about what is safe to run. You also still have stock recovery installed. Is this a correct interpretation?
I don't know the best answer for that. The stable CM10.2.1 is supposed to be safe, but I have no proof of that. I know a lot of users have reported bricked devices with CM11, with no explainable reason why. I suspect TRIM with the bad chip.
It is a tough question. Maybe someone else has some comments.

Exactly what I meant to say. Thanks for explaining it better leapinlar
I just had another thought. You say you do a factory reset and it helps temporarily. You might try going to mounts and storage in CWM and format 'data and datamedia'. That is a real format of /data. The factory reset and format /data does not really format /data. It erases the contents of /data except the /data/media folder where your emulated internal sdcard is. So it is an erase function rather than a format. Also some of your lag may be due to your media files. A clean real format of /data may help. Also format /cache, that is where your system dalvik cache files are stored and if you're are not factory reseting, you should do the cache separately.
