[Nook HD, HD+ Android Development] ST Dog:
Only thing I don't like with CM is the lack of casting.

Small gapps packages aren't a limitation as everything else is available. Once things update they aren't in /system anyway, so no help with storage either.

It's just convenience and most don't use more than a few apps from the package anyway.

If I ever get time I'll look at a SD install, but I don't see it happening unless someone else does it.
[Nook HD, HD+ Android Development] ieatabiscuit:
You know he has an AOSP release that does do casting right? Only down side for you is that there's no current SD install though. I wonder if there's a way to modify the existing setup to be bootable from SD? I don't know the stuff to even begin doing it personally, I find ways to tinker on existing software, and I mess with hardware mostly, so best you can do is ask around. amaces is pretty quiet now days, letting the thread vets handle things while he hammers out the ROM, but perhaps ask belfastraven if there's any way to do it? You might get your wish, might not, but it'd be worth an effort I think.
[Nook HD, HD+ Android Development] ybarra:
So, I'm in the same boat as the other guy in that I'm looking at this for a Nook HD to get around the 8GB storage limitation. I'd rather use EMMC, but every attempt and every ROM I've used fails to be able to copy apps to the SD card (gives some permissions error, I think another guy posted a thread with no solution). Can someone confirm whether or not it's possible to use adopted storage and move apps to SD card with MM and a Nook HD?
[Nook HD, HD+ Android Development] ST Dog:
Best asked in the MM thread.

Alternatively you could fake it. Recall we are basically using linux at the kernel level.

Format the card as ext4 and mount as /data early in the init process. It has drawbacks, but can be done.

(If that doesn't make sense to you, then you probably are ready to try it)

That's basically what adopted storage does, but it encrypts the card too.
[Nook HD, HD+ Android Development] jbbandos:
/me feeling sad now... My HD+ internal emmc has become read-only (can't even format in recovery), so I was hoping to find a solution here, but since the old CM11 ROM still tries to create a cache in emmc, it fails.
[Nook HD, HD+ Android Development] ST Dog:
While you could tweak the SD install to not use EMMC (I think one of the CM10 installs was like that), I think you'd be better off replacing the tablet.

Replacement Nooks are out for relatively cheap prices (depending on the internal storage) and your existing tablet give you some spare parts.

I see a 36GB in Gray for $100 on eBay. And other listing has 2 of the same for $90 each.

Of course yours and other used ones have old batteries. It may just be time to move on.

That said, I'm still using my HD. Nothing in the 7" size that I like, and I want the smaller size.

But there are some nice 8" and 10" options.
[Nook HD, HD+ Android Development] jbbandos:
Mine has a new battery, I had just replaced it one month ago. Now I am thinking if the weirdness I was seeing wasn't the emmc starting to die.

I'll check ebay, but in the meantime I got a cheap chinese tablet (chuwi hi8) and it seems to work quite well, despite the old android (4.4).

Maybe I could use the screen and touch interface with a raspberry pi, if I could get a hdmi adapter for it.
[Nook HD, HD+ Android Development] ST Dog:
May have been. Since you have a good battery, that makes a used HD+ a better option.

I'm not looking forward to my HD dying.
[Nook HD, HD+ Android Development] xdajauser:
Hello,

I had a problem when I turned on the tablet this morning:

/ Bootdata / BCB missing. Running recovery

And then the recovery:

When boot [Nook HD / HD +] [SD Install] [4.4] CM11.0 (KitKat):

CWM-based Recovery for HD+ SD CM11.0/sgt7 v6.0.4.5

E: Can't mount/cache/recovery/command

E: Can't mount/cache/recovery/log/

E: Can not mount / cache / recovery / log /

E: Can not open / cache / recovery / log /

E: Can not mount / cache / recovery / last_log /

E: Can not open / cache / recovery / last_log /

The same happens in CM10.1 / SGT7 SD / Hybrid Development and in [Nook HD / HD +] [SD Install] [4.4] CM11.0 (KitKat). When I try to use some of the recovery options it says that it can not mount the partitions. I had been using them for months without problems. It may be that the last time you used it, you would change some of the root options. Although it is not safe.

What should I do? Is it a brick? It has a solution?

---------- Post added at 06:21 PM ---------- Previous post was at 05:45 PM ----------

I have created a new SD but the boot error is the same and I can not use the install zip option because it fails by mounting the E: can't mount /emmc partition.

I'm afraid to use wipe data / factory reset because I'm afraid the original rom will be erased. This option only resets the system to factory values?
[Nook HD, HD+ Android Development] ST Dog:
Factory reset just clears the data partition and caches. It won't mess with the ROM or the factory backup.

But sounds like your EMMC is bad. I recall some SD card version the will run with bad EMMC. Search the HD/HD+ threads.
[Nook HD, HD+ Android Development] leapinlar:
Sounds like a brick. CM11 can brick internal memory even if running from SD. If it is a brick the only solution is to run a noemmc version on SD.

And a factory reset never wipes the system rom.
[Nook HD, HD+ Android Development] xdajauser:
Then how can I be sure it's a brick? Can i do some checking?

And how can I use a noemmc version from SD?

Then if I understood correctly, it is no longer possible to use the original stock room, or install some room in the internal memory?

Can you suggest some thread with instructions?

Thank you
[Nook HD, HD+ Android Development] ST Dog:
Correct. Internal memory, EMMC, is broke.
[Nook HD, HD+ Android Development] xdajauser:
But how could it break without there was no blow or fall?

Is there any check that can be made?

---------- Post added at 07:22 PM ---------- Previous post was at 07:20 PM ----------

I mean, if you can break internal memory only by changing system settings?

---------- Post added at 07:30 PM ---------- Previous post was at 07:22 PM ----------

I thought that the versions that had installed in SD were versions nonemmc since they were initiated from the SD. But I'm insecure.

Also these seem to not work because they fail to mount partitions when I try to use some recovery option ...
[Nook HD, HD+ Android Development] leapinlar:
No, standard SD installs still use some portions of internal memory. And it does not brick because of physical damage, it is because CM11 tries to do some memory repairs periodically that sometimes bricks certain devices. It is non repairable.

Search the forum for the term "noemmc" to find threads that discuss that and provides links to the roms. There is a check but I don't remember the thread. The search should find it.
[Nook HD, HD+ Android Development] xdajauser:
Hello again

1) I need to be sure that the memory is damaged and is irrecoverable. But I do not know exactly what to do for it.

1.a) I am trying to access the computer using adb.

With the following commands I get these results:

parted /dev/block/mmcblk0

parted /dev/block/mmcblk0

adb devices

/sbin/sh: adb: not found

This last command seems clear, but is there any other command I could use?

1.b) Is there any option like this that gets access to memory and install a stock rom in Nook Color?

http://raywaldo.com/2012/06/how-to-un-brick-a-nook-tablet-8gb-or-16gb/

(Sorry for the link, it's just to explain)

2) I found the threads on noemmc and I'm trying a new SD.

2.a) In this link is said that in some cases it is possible to recover the device if knowing the serial number?

http://xdaforums.com/showthread.php?t=2435055

2.b) In this thread explains how to create a SD noemmc, but when I put it on the tablet is not recognized by the PC. According to the guide now would have to copy the rom via adb.

http://xdaforums.com/showthread.php?t=2221289&page=7

Any suggestions?

I keep trying? :confused:

Relived the tablet using a noemmc rom by following this guide!! :good:

I found it on this thread

http://xdaforums.com/showthread.php?t=2221289&page=17

But I would like to do some other test to try to access the memory and repair it.

I'll keep trying!! :fingers-crossed:

Thanks for the directions :)
[Nook HD, HD+ Android Development] xdajauser:
bad news!! :crying:

My tablet died definitely? :(

Yesterday when I went to use it, did not turn on the screen, when I unlocked it. Toward the attempt, but it always went out. Then holding down the start button I turned it off.

But when I try to turn it on again, it stays on the initial screen of cyanoboot and a message appears that says: (SDC) LOADING BOOT ...

Testing, I could access the recovery but from there I can not mount the path / boot

I remind you that I am currently using a noemmc since it seems that the emmc has crashed.

I tried the card on the PC and it shows three partitions and the correct content, but when I use the card on the tablet it seems unable to mount the partitions

What I can do? Is the tablet completely broken? :fingers-crossed:

---------- Post added at 05:51 PM ---------- Previous post was at 05:48 PM ----------

The battery seems to be working and the described behavior is repeated, when it is connected to the power outlet, with the battery and connected to the PC ...

---------- Post added at 06:00 PM ---------- Previous post was at 05:51 PM ----------

Looking at what has happened, a question appears. Do you think the tablet would have lived longer, had it used only the stock rom? :confused:
[Nook HD, HD+ Android Development] Nobody012345:
The gapps is failed to install

I follow the instruction step by step.

1. Write the cm11 image to a sdcard(Sandisk class 4, 16G)

2. Boot from the sdcard(succeed)

3. install "cm-11-20141122-UNOFFICIAL-bok-ovation"(succeed)

4. install gapps 4.4 stock(fail), the error message is "no enough space" or the same meaning.

The gapps cannot be installed, the error message is "no enough space"(something like that).

The sdcard is 16G in size but the gapps file is only 680M. Is the space of sdcard shrink after the boot image is written in it?
[Nook HD, HD+ Android Development] digixmax:
GApps content gets installed into the same /system partition which hosts the ROM itself and which I seem to recall was sized to <=1GB (you can use partition tool like MiniTool Partition Wizard to find the exact size of all partitions on the SD) hence there is not enough space to fit a GApps package of 680MB and you will need to find a much smaller-size GApps package.

Alternatively, you can manually create a SD partition layout with customized partition sizing -- see https://xdaforums.com/showpost.php?p=49007593&postcount=84.
[Nook HD, HD+ Android Development] Nobody012345:
Thanks for your prompt reply

I don't want to root my nook HD+ but to create an N2A type sdcard.

What is the proportional of system and data partitions?

Which partition is for bok-ovation and which for gapps?

I choose to use Android 4.4 because I think the higher verisons are probably more demanding, isn't it?

Thanks again.
[Nook HD, HD+ Android Development] digixmax:
They are both installed into the /system partition.
[Nook HD, HD+ Android Development] Nobody012345:

I found that the cm11 is unstable. I just wanted to try cm12 without rooting my nook hd+?.

How do I make a cm12 n2a type sdcard?
[Nook HD, HD+ Android Development] ST Dog:
Odd. I never found cm11 unstable on the card.

Used it for over 2 years on 4 Nook HD tablets, before moving to EMMC on one (other 3 got new tablets).

No one ever built an SD version. I tried to get info to make one, but no luck.

CM12 /12.1 development switched to CM13 before it was really usable.
[Nook HD, HD+ Android Development] Nobody012345:
Some problems occurred

Bluetooth doesn't work at all. Wi-fi often on and off, I need to shut it down and turn it on again in order to regain the internet access. But I found that it doesn't need an usb driver to connect a nook hd+ to a computer.

Sometime, the screen is suddenly black when an app is running, especially the browser.

The apps screen is smaller than the main screen and its background color is plain white and no any graphs. It is different from the main screen.

I use a sandisk class 4 sdcard as recommenced. Therefore, the problems may be caused by the ovation or gapps package.

Would you please tell me where do I get the reliable package to build a sdcard? Is really no one successfully to build an n2a sdcard with cm12 or above?

Thanks.
[Nook HD, HD+ Android Development] ST Dog:
A few of those sound familiar, even with EMMC. But not often enough to call it unstable. Not eVen daily issues.

BT worked fine except my keyboard. Same with EMMC.

Not sure anymore. I haven't used it in 2 years. Maybe more. It was the last one posted on XDA.

I wanted newer builds, Still CM11, to switched to EMMC.
[Nook HD, HD+ Android Development] Nobody012345:
Acutally, I like this alternative OS for my nook hd+ even though it is not 100% perfect.(Sometimes, it will suddenly halt and you need to wait several minutes until it back to normal or power it down immediately.)

I think cm11 is much better than the nook's original heavy modified Android 4. At least, it opens up a board areas for those who want to extend the abilities of their pretty powerful tablets.

Although Sandisk class 4 sd card is recommended, I found that another brand with different class just working fine, but definitely not faster, with my nook. It is Adata class 10 with 16g capacity.

I tried to install aroma and super gapps but failed. I think only stock gapps could be installed on nook hd+.
[Nook HD, HD+ Android Development] ST Dog:
Limited space on /system. You can add all the rest from the Play Store.

Even less space on EMMC. CM12+ you only have room for nano or pico (forget st tbe moment).
[Nook HD, HD+ Android Development] xdause:
can someone post the link to the sdcard-ovation-cm11.0-v1.img file listed on the first post? Reason I am asking is because that link (I have gone to) but all the links I clicked on sent me to virus sites and fake downloads and I've tried multiple times.
[Nook HD, HD+ Android Development] ST Dog:
If you look around (this thread even?) There should be instructions for making a bootable SD card for installing, and customizing the partirions.

I've probably got the CM11 image mentioned somewhere, but it's not on my main computer anymore.

Help please

Hi guys. As always, thank you for your hard work.

I feel like a noob (Well, I am anyway) with every new android device.

Bought the nook hd+ and installed unofficial carbon.

From there I tried going back to stock with no luck (Error 7 - took out codes from file to avoid error 7 but still failed).

Tried installing this rom from EMMC but failed (bad file).

Copied again and tried again with no luck - android drops dead :(

(Can't read the SD card at all on CWM - can't mount too).

Am I stuck on Carbon rom, or is there any hope for me?

Thanks.

PS I have tried searching but feel stuck at this stage. Also a bit scared of bricking the device.
[Nook HD, HD+ Android Development] king200:
If I understand correctly, your question might belong http://xdaforums.com/showthread.php?t=2579945 but I'll say what I'd try here and apologize for the steal.

Start with the procedure that you used to install the Carbon Rom. You needed to use a bootable sdcard for that. Instead of installing Carbon Rom, there is a stock .zip file that has the stock rom either v2.1 or 2.2. There is then a procedure to remove the CWM recovery and you are back to stock.

If you absolutely cannot boot anything from your MicroSdCard, you might like 4.4 KitKat, internal, EMMC, http://iamafanof.wordpress.com/2013/12/20/cm11-0-kitkat-android-4-4-2-for-nook-hd-xx-20dec2013. The TWRP mentioned there,flash_recovery_TWRP_2.6.3.0_internal.zip,

If you need more, please respond in the xda thread I mentioned or PM me. You can get back to stock.

Installed today for Nook HD+ and it's very slow. Is it due to low sd card speed or I installed something wrong? (followed the instructions properly i think).

Edit: Seems like i can't even pass the setup stage.
[Nook HD, HD+ Android Development] leapinlar:
It is not slow because of being installed to SD unless you used an inferior SD. What brand and class did you use. The best is a SanDisk class 4.

Well, i can't tell which brand it is, nothing is written on it except that its MicroSd hc 4gb class 4.

Edit: It also had some code written on it and when I googled it, it seems that this sd card is Kingston one,
[Nook HD, HD+ Android Development] SynGamer:
Before doing this, can someone clarify where the EMMC is? I always see "internal SD" and then external SD, but I've never had a tutorial/ROM tell me to put files on the EMMC. Also, will this ROM completely wipe my Nook HD+? I mean EVERYTHING, including the Nook OS? I don't want to dual-boot or have an Android ROM running on top of the Nook OS.
[Nook HD, HD+ Android Development] asakurato:
No doing this won't erase anything on your nook. When you'll write image to sdcard you will see install from /emmc and you will install rom from nook internal storage.

[Nook HD, HD+ Android Development] leapinlar:
EMMC means Embedded Multi-Media Card. It is the chip that is built into the device. It is another name for internal. But the terminology gets confusing sometimes as emmc is sometimes what some users call internal sdcard, which is really just the portion of emmc devoted to media files.

And this install puts most of the files on the SD and only uses a very small part of emmc. But the files it does put on emmc do not replace or interfere with the ROM installed on emmc (stock). If you boot with the SD removed, stock is not changed at all.

So this ROM is dual booting.
[Nook HD, HD+ Android Development] SynGamer:
Alright, I have a SanDisk Class 4 microSD with the IMG file written to it using the disk tool (I did step 1...). I reboot with the SD card in and it just goes to the Nook loading screen and then boots into Nook. Am I doing something wrong?

EDIT: is there any special key combo I have to do when booting with the SD card in? As soon as I turn the Nook HD+ on, the nook logo appears for about 10-15 seconds, then the nook loading screen...
[Nook HD, HD+ Android Development] leapinlar:
No keys combos needed. It should boot to the standard nook logo for a few seconds followed by a cyanoboot logo. If you are not getting that, it is not booting to SD. There are many factors that can make it not boot. You have the right card, but are you using an external USB card reader? Are you running win32diskimager in administrator mode? Sometimes you just have to keep burning and/or booting. But be sure to let it boot completely once every 8 times you try or stock will reset itself.
[Nook HD, HD+ Android Development] SynGamer:
I just remembered that I used this same Class 4SanDisk 4GB mircoSDHC card to flash (same method as this) CM10.x (can't remember). I still go to the Nook OS initially, but when booting is done, it's in Android with Zeam Launcher I think. Could that be causing an issue?

EDIT: reburned the IMG and it's still going to the Nook loading screen (white bg, grey text) and then loading into Android.
[Nook HD, HD+ Android Development] leapinlar:
What you have on internal memory makes no difference.

You say it loads into Android. You mean stock OS or CM? Both are Android. But like I said, it makes no difference to the SD.
[Nook HD, HD+ Android Development] anactoraaron:
Make sure that the SD card is marked as an active partition. Even then it took mine about 20 tries to get it to boot. Just be patient. :good:
