root the device (should be with CM 10.1) and download emmc check from the appstore

you are welcome my friend

I was under the impression that the emmc check app from the play store was only meant for finding out the type of NAND device inside your Nook. IIRC, The actual sanity check performed by it is for a different (older) type of emmc brick bug and not the current TRIM related brick that could be observed in some CM 10.2 builds, which had TRIM enabled. So I wouldn't conclude yet, that your device is safe ... Better cross check the NAND type with the CM wiki article. (Sorry I don't have the link at hand. Just google it.)

The eMMC that has the bug is named MAG2GA.
I have this one too, but I'm running the TRIMfix Kernel for testing.

eMMC chip:
Type: SEM32G

CID (huge number)
FwRev: 0x90
Does this mean it's ok?

Yes, it's perfectly fine for you to run CM10.2 with no problems. Your device does not have the chip with the issue.
Your chip is: SEM32G, not MAG2GA. The MAG2GA chip is the one specifically with the issue.
All the best.

Just got my refurbished Nook HD+. Does it have to be rooted to get the correct information? I have made a backup of my stock and installed the emmc check from the Play store and it is saying I have the affected chip. This was done while running stock.
So if I have the affected chip, what exactly does that mean? I was planing on running CM 10.1.3 on it which I think is not affected. Will my device get slow as the memory fills up?

If you're going to run CM 10.1.3-stable, you're good to go. You don't have to worry about anything.
If however, you're planning to install CM 10.2 or decide to upgrade to it; you may have issues with the performance being degraded, as CM 10.2 is based on Android 4.3; and 4.3 introduced a new way of managing storage, using something called TRIM in attempt to increase performance.
If you upgrade to CM 10.2, and then revert back to Stock ROM, or CM 10.1.3 (or any other ROM), you will still notice the issues; as your hardware has been affected. If you try to install the TRIM kernel, that could also brick your device.
I'd only install CyanogenMod 10.1.3 (stable) and stick to it. Perhaps in the future we could solve this EMMC TRIM hardware issue; as the 2012 Nexus 7 uses the same chip, and it's been patched via a software update. In the future, perhaps we could port that patch onto the Nook.
Again, for now CM 10.1.3 is your best route.
All the best.

Even if you run CM10.1.3, you can still get lag, which is what TRIM is supposed to fix (TRIM is a repair utility, not a new way of storage). It makes no difference which you run, CM10.1.3 or CM10.2, it is possible to get lag. The difference between the two is CM10.2 has the TRIM utility built in and CM10.1.3 does not.
That said, I run CM10.1.3 and have never experienced lag. But I have a SEM32G chip too (not an buggy chip). However, many users have reported lag on CM10.1.3. Since TRIM is not built in, they run the TRIM app from the Play Store. And if they have the affected chip, some have reported a brick.

Hello guys,
I just discovered this thread and it seems that I got a bad chip (MAG2GA). Unfortunatly I installed CM 10.2 (20131106-NIGHTLY) the day I got the tablet (last week). So far I am pretty happy with the tablet but sometimes some apps are crashing. Most of the time it is chrome but not exlusivly.
Should I go back to 10.1 because of the memory chip i got? Should I send the tablet back and ask for a different device? This could be costly because I ordered in the USA but live in Germany.
Will future updates fix the problems? I planed to use the tablet at least for two years and so future updates should be possible for my tablet.
Thanks for your responses, best whishes.

So my chip is the supposed bad one. I am on liquid 4.3 and honestly it runs better than it did stock. I don't have any random errors or anything. Should I not be on any 4.3 ROM even though it says my chip is sane?

Supposedly brand new but with a MAG2GA chip. Should I be angry? If it has that chip is actually a refurb being sold as new?

No, they have stacks of these things they are trying to get rid of. They over ordered months ago and are trying to reduce inventory to improve their financial position. That's why the lowered prices. I don't think they are making any new ones.

If the revision number is the actual problem, then I should be OK as I have an 06. Need to try the trim command and see what happens.

I am on 10.1.3 and I ran that program and have the MAG2GA and under the Brick Bug? it lists No. Sane Chip.
I guess the program is wrong. lol

The brickbug app is not checking for the mag2ga chip as being faulty as that's not what it was designed for.

What if you have the bad chip?
If you do have the affected chip, any predictions on what the future looks like? Are these the only rays of hope:
1) Someone ports the Nexus 7 patch to 10.2
2) Google integrates the patch logic into android core 4.4 so CM11 might be safe on Nooks?
It sounds like stock nook OS is based on 4.0.3... so doesn't sound like B&N is too hungry to push the stock OS past this barrier.

[Q] updating from CM 10.1 to CM 10.2

ok guys I'm sort of a newbie to this stuff so i would really love it if you guys could help me out! I'm trying to update my CM 10.1 to CM 10.2 so that i can get 4.3 and i found a post about it being possible to do it on a nook, so i downloaded all the stuff i needed just like when i put 10.1 on it and everything seemed to go fine when i was downloading it but when i booted it up none of my gapps are working (and i got the 4.3 apps that i was supposed to get) and it still says that i am running on 4.2.2....
now I'm sure i have done something wrong and it's probably the easiest fix in the world but if there is anyone out there who can tell me how i need to go about doing this update i would be very appreciative thank you very much and i hope you all have a great day!

Are you trying to update CM10.1 that you installed on emmc? If so, you can't. The version of CM10.2 that is available is for SD installs, not emmc. Flashing it to emmc will not work.

CM10.1 to 10.2 upgrade for sdcard builds
After several tries that resulted in one issue or another, I successfully updated my sdcard install from CM10.1 to CM10.2. I think my unsuccessfuly attempts failed because of gapps. One of the links in th CM10.2 thread pointed to a GAPPS 4.3 "Core" zip file that ultimately worked for me. The other gapps 4.3 files usually resulted in the "two cLock app" error and I could never connect to Google service (Play Store and GMail, in particular). My wi-fi indicator on the status bar remained grey, never turning blue. All of my network-dependent apps worked (CNN, XDA, etc.) except for those that depend on Google.
Other issues that seem consistent:
1. Can't see internal storage (emmc); I can't find it anywhere (usual contents of /storage have been apparently moved anyway)
2. Weather Channel app had to be set up from scratch
3. News & Weather app/widget is gone
4. Background image seems to get reset occasionally (from a live wallpaper that I selected); not necessarily limited to CM10.2, but seems to be more prevalent now than with CM10.1
...
999. I'mnot certain if it is related to CM10.2, but the Engadget app has been pretty unstable since the upgrade.

[Q] Nightly CM10.2 Build Info?

How could I find info related to each CM10.2 nightly build for Nook HD+?
I would like to know what change(s) are in each build so that I could either update it or just skip it.

IF you have CM10.x already installed, just go into settings -- about tablet -- cyanogenmod updates
Then click on the available update for a changelog.
This will list both cm10.1 and 10.2 nightlies and the changelogs!

If you're running a nightly earlier than 8-16 for 10.2, you should update immediately to avoid getting bitten by a likely firmware bricking bug.

verygreen says he thinks he has a workaround for the firmware bug in the Samsung emmc. Luckely, I have the SEM32G (sandisk) emmc which doesn't seem to be affected. It seemed to be a bit snappier running a ROM with TRIM activated.

Mine's affected by the emmc bricking bug, and I've used LagFix three or four times on CM10.1 without problems. Guess I can consider myself lucky.

[Q] HELP can't see KFHD7 in My Computer (Custom Rom)

Hi,
Problem i have is the device isnt showing up in "My Computer".
It Makes a shound when connected, and it's in the Device Manager. Also.
Any help would be gr8!!!!!!!

please, any help -
Try reinstalling the drivers for the MTP device in then device manager. I think this usually happens when coming from stock and going to another ROM.

I run cm 10.1 with a tablet patch I made for the latest cm 10.1, I'm avoiding cm 10.2 for a few more months before I switch to it, I heard there's small performance issues because of some files not being optimized, as well as people in the market having to update their apps to work with the new is, as well as some fstrim things that need a little more investigating before I use it. I mean I am pretty sure most people are using it instead of cm 10.1 now, but I personally want to wait a bit.
Idk about your crashes but it could just be a bad flash or you used the wrong gapps package. I am not too familiar with the ROM you are using, since I haven't ever used it. The way I look at it is usually the closer you are to stock the less bulky the os would be, least that's how a PC operating system would work sorta. Don't know if the same holds true for android.

MAG2GA rev6 what is safe for me to install to emmc?

I have been attempting to sort through all the information but, have come to a standstill. I have the MAG2GA rev6 emmc. I have heard that rev 5 is the one to worry about but I wanted to double check.
I am looking to install CM10.2 to EMMC, is this safe?
Is using trim safe?
I have heard mention of a special kernel made by verygreen that incorporates a patch from the nexus 7 is this something I would need?

That patch is now part of CM10.2 stable. No one has reported a brick since he did that. But that does not mean it won't happen.

Certain batches of the Nexus 7 contained the same faulty Samsung eMMC. Google engineers patched it up. Verygreen viewed the fix and implemented it for CM 10.2.
No one has report a brick for months now. Seems to be safe.

[Q] Which build to install?

I've got an HD+ that has been sitting, not being used for at least 6 months...finally found the charger and fired it up today. I'd like to get the best recommended build installed on it for performance (including dealing with TRIM issues on the EMMC), etc. Currently I'm running:
10.1.3-ovation
Kernel: 3.0.31-green+

Can someone point me in the right direction? I'm normally fine handling the install once I get there but there's always so many builds to choose from LOL!
Thanks!

That is exactly the build I use. I have seen no need to upgrade to anything newer. It is stable and does everything I want it to do. And you can be in control of trim by getting the app Lagfree from the Play Store.

Any suggestions on how to get the best performance? Still feels rather laggy to me...recommendations on launchers etc.?

FWIW, I am running CM11 snapshot M11 (& Nova Launcher) on my HD+ and it works pretty well for my use of the tablet (email/web surfing/video streaming (hulu/netflix)).
If you plan to upgrade from CM10 to CM11, see http://forum.xda-developers.com/nook-tablet/general/how-to-updating-hd-hd-internal-emmc-to-t2863171 for info/pointers.
Going back to 10.1.3 from CM11. I seem to remember there's something i need to do besides a complete wipe, but I don't remember what it is.
Is there something else?

Great. Thank you
I had been running CM 10.1 SD hybrid install from bokbokan and recently updated to his SD CM11 install.
I enjoyed it but decided to switch to an emmc build (and try to find one on which I could get tabletui back!) so I started cleaning up my stock rom so I could back it up and then place stock on SD using verygreen's files.
However, I discovered some tweaks (and an unknown functionality of Apex launcher for the home button) for rooted stock that made me happier with my setup on stock than I have been in a while.
You might want to give stock a chance again. I'm going to make a backup of my setup and then see if I can get any Xposed modules working. If some of my favorite modules work, then I'll be very happy indeed.

Been Googling this till it crosseyed. Where can I find a TWRP recovery older than 2.6.3? Or is rooted stock w/ Apex or Nova really the happiest compromise?

Why do you want TWRP older than 2.6.3? If it is so you can install an older ROM or zip, just go to my HD/HD+ CWM thread linked in my signature and make the bootable CWM per item 1a.
Sent from my BN NookHD+ using XDA Premium HD app
Because I wanted to downgrade from CM11 to 10.1.3 and I prefer TWRP over CWM. I may still have that SD from when I first rooted my HD+.
