Users just be aware that even though he posted this on the SD install thread, his description was for an emmc install.
[Nook HD, HD+ Android Development] ST Dog:
And chance of an updated ROM? I'st been 2 months, and I'm sure CM11 has improved in that time.

Is there a way to use the EMMC ROM without a lot of difficulty?

If it takes a lot of changes, could they be scripted so we can make our own more easily?
[Nook HD, HD+ Android Development] Ninja515:
Thanks for the rom, it makes my nook way more fun to use.
[Nook HD, HD+ Android Development] GMTN:
I'm thinking of updating my wife's stock unit with nova launcher. If i did this, what storage will the KK use for apps, pictures, etc ? Is it going to store things in the 32 internal or the external 4 gb micro sd card that I'll be using for the install. Also, will i still be able to restore her apps that i installed from an 'unknown sources' from my titanium backups or are those pretty much gone.

Lastly, is there an advantage between this over the EMMC install ? She uses it for surfing, YouTube but i really want to Google now hands-free search this but that's only available after 4.1 .

Thanks
[Nook HD, HD+ Android Development] ST Dog:
The launcher won't affect app storage.

If you use he SD card, then apps will be stored on it as it's the primary system partition. The EMMC is treated like an external card, as secondary storage.

Restoring from TB should work fine.

Using the SD card install v/.s EMMC allows you to easily revert to the stock system. No changes to it have been made.

You can back up the whole thing just by making a image form the SD card.

You could even have two cards, one for her and one for you. Power off, swap cards, and it's a whole new tablet.

It allowed my daughter to use my tablet like it was her's on a trip once when her battery died.

Everything was exactly the same as on her device.
[Nook HD, HD+ Android Development] DeanGibson:
Updates?

In particular, USB Host mode doesn't seem to work at all, which is the main reason I moved from stock.
[Nook HD, HD+ Android Development] ST Dog:
Also wi-fi Direct/Miracast. I recently got a new BD player that supports it, but the Nook doesn't, not stock or latest SD card CM11.

bokbokan has disappeared. His last post was this thread in August, but he's been on the forum as recently as this morning.
[Nook HD, HD+ Android Development] DeanGibson:
USB host mode working ...

I now have USB host mode working on Verygreen's SDcard variant of CM11 (2014-8-17 date).
[Nook HD, HD+ Android Development] ST Dog:
I don't see an HD (hummingbird) SD card install from verygreen, only HD+ (ovation)
[Nook HD, HD+ Android Development] DeanGibson:
That's all I saw as well (I have the HD+).
[Nook HD, HD+ Android Development] bokbokan:
Sorry for not updating for a long time.

OP updated 20141122
[Nook HD, HD+ Android Development] ST Dog:
Any notable changes before I go digging through the CM11 change logs?

Working Miracast/WiFi Direct would be nice.
[Nook HD, HD+ Android Development] m1complex:
Thanks for re-invigorating this project! I'm incredibly pleased to see that it hasn't been abandoned.
[Nook HD, HD+ Android Development] DeanGibson:
USB host mode?

Your 8/5 SD-bootable update didn't support (as far as I could tell) USB host mode. Does your recent version?
[Nook HD, HD+ Android Development] Aerlock:
I'm going to guess not since I'm not able to get it working and from what I can tell in this post it looks like the kernel needs to have it enabled so its not going to work unless bokbokan puts out another build with it enabled.

[Nook HD, HD+ Android Development] mmnspeed:
I have installed the ROM on my sandisk class 4 16gb card with some difficulty. The only issue I encountered is that it crashes at times when I am multitasking.Also the playstore is pathetically slow.Could someone please tell me why it functions so slowly?I couldn't find the pa gapps in the op,so used a download from the CyanogenMod page,for kitkat.The lighter package,around 83mb.Please help me at least run the playstore properly,or is threre no fix?The ROM otherwise is very responsive so I suspect I must have gone wrong somewhere with the playstore.

---------- Post added at 04:13 PM ---------- Previous post was at 03:54 PM ----------

A slightly related question.If I want to change the gapps of this install,can I format the system in cwm?I am scared that it might mess up the emmc.
[Nook HD, HD+ Android Development] leapinlar:
I don't know the answers to your first questions since I don't run CM11, but if you use the CWM from the image in the OP it will only format the /system on the SD, not touch the /system on internal memory.
[Nook HD, HD+ Android Development] mmnspeed:
Thanks for the reply.Sorry to bother you with a few more questions.Could you recommend the best ROM for hybrid SD install,I mean whether I should use jb or stick to kitkat?Also I saw a sandisk 32 GB class 4 card for sale,I am thinking of buying it.Will the larger size compared to 16gb have some adverse effect on performance?thanks.
[Nook HD, HD+ Android Development] leapinlar:
No, I would jump on that 32GB. Also as I said earlier, I don't run kitkat. I like CM10.1.3. Very stable and safe (some devices are bricked by kitkat, even SD installs).
[Nook HD, HD+ Android Development] mmnspeed:
Thanks..would go to that version then....:)...if possible please provide the link for the exact version you are using..

Edit:I found another thread of the developer with cm10.1 SD emmc hybrid install,but sadly all files seem to have been deleted..any help in finding them would be appreciated...
[Nook HD, HD+ Android Development] leapinlar:
I run my CM10.1 on emmc. Bokbokan seems to have deleted all his sdcard versions. If you definitely want to run CM10.1on sdcard, verygreen's versions still are available. He also has CM10.2 versions available.
[Nook HD, HD+ Android Development] mmnspeed:
I experimented a lot in the recent days..:)..used the recoveries and instructions that you have given..I found the cm10.1 stable build a bit slow compared to kitkat(both emmc versions),but more stable..finally settled with emmc cm11 M12 official build,reboots every now and then..wonder why..but overall is exceptionally smooth.. Only thing I have left out is going back to stock and removing cwm as well...thanks for all the work you guys have done all these years and the effort in compiling all of it...also if you have any suggestions regarding which build of 10.1 you are using,please do share it...I find this rebooting issue annoying in kitkat..otherwise it gives a new lease of life to the tablet..and do share your opinion on the cm11 official build,whether it has any chances of messing up with the emmc..so far looks far from that..thanks..

Oh and I forgot .there are graphic glitches at times in cm11 kitkat..have to turn off and reboot it to get it working again..hope I haven't messed anything permanently
[Nook HD, HD+ Android Development] fatfingered:
Wonder if OP or anyone else can answer this. I recently bought a stock Nook HD to play around with. Yesterday I was able to create sdcard cyanoboot and have a working SD install of cm11 using OP's rom. I had to "find" the PA-Gapps as that link is now dead.

Can I replace the cm-11-20141122-UNOFFICIAL-bok-hummingbird rom with another rom such as the cm11 hummingbird nightly roms? Or is OP's rom specifically configured to run from the sd card install?

I'm currently using a Samsung 16gb c6 card and it runs very well.
[Nook HD, HD+ Android Development] :
There are SD install Roms (external sd) and emmc (internal SD) install Roms. The nightlies are emmc and can't be installed on external SD. So no you can't.
[Nook HD, HD+ Android Development] fatfingered:
Thanks.

So seeing that there aren't many threads with sd install cm11 roms for the Nook HD, I guess this one is it. Or alternatively, I can install the newer nightly cm11 to emmc and put the stock Nook rom on the sd.
[Nook HD, HD+ Android Development] :
Yes, I think the stock SD install runs pretty good. Most of the emmc installs have quite a few bugs. Mainly random reboots and screen flickering, unfortunately. I'd recommend a build, but I haven't played with mine much lately, and don't remember what worked best.
[Nook HD, HD+ Android Development] panamamike:
I'm seeing the same issues you've encountered on the SD hybrid install in your earlier post.

http://xdaforums.com/showpost.php?p=60711119&postcount=361

Namely, crash during multi-tasking as well as slow playstore download. I've also experience crashing of playstore by just entering search.

The emmc version you're referencing, is that available as an SD install?
[Nook HD, HD+ Android Development] panamamike:
Speed needed to avoid crashing?

What speed does the card need to be in order to avoid crashing and freezing? micoSD card speeds vary. Could you share recommended speed by CrystalMark terms. 4k Q32 write? Seems 1.7 is good enough, but could it be slower? Should I get faster?
[Nook HD, HD+ Android Development] digixmax:
FWIW, when I used to run CM off SD, I used Sandisk class 4 almost exclusively with great results. Another great benefit of using class 4 is the cards tend to be very inexpensive, e.g., 16GB sold on eBay for under $8 shipped.
[Nook HD, HD+ Android Development] mmnspeed:
I'm afraid not...but if you want something really stable,use the official CyanogenMod 10.1.3 build...it is pretty stable..use nova launcher with it..it is emmc install,but I don't see any reason why you shouldn't be using it instead of stock...
[Nook HD, HD+ Android Development] panamamike:
Thanks for the info. I wanted to use a larger capacity sd card. These days most of them are class 6 and above. I also did read that some of the class 4 cards also suffer from slower 4k q32 speeds. I'm thinking the reason the class 4 cards work were because they had faster 4k q32 speeds. I'm guessing it just so happened folks were using the smaller capacity cards which happen to have faster 4k q32 speeds.

---------- Post added at 09:35 AM ---------- Previous post was at 09:33 AM ----------

Thanks for the suggestion. I ended up reinstalling CM 11, however I modified the partition sizes making the boot and system partion larger. This looks to have made the OS more stable. Will play with it and see if I can live with it or not.

---------- Post added at 09:47 AM ---------- Previous post was at 09:35 AM ----------

Is this possible? I don't want to root may stock install if possible. I have the rev 06 of the Samsung fix. Supposedly it's ok to trim this eMMC.

[Nook HD, HD+ Android Development] panamamike:
Can't mount error. What to do?

I installed cynogenmod on my Nook HD+ on the SD card specifically to avoid bricking my Nook HD+. I figure if something goes wrong with the image, I can remove the microsd and be fine.

That day came, the bootloader was reporting that the nook couldn't load bootdata/BCB/missing and unable to mount.

Tried removing the sd card only to be greeted with a black screen. Any idea why I'm having this issue? I did try the following.

1: Format the cache. That did allow the boot sequence to go back to what seemed normal. It attempted to boot, but couldn't complete.

2: I also tried the commands to clear up the boot loop. Again seemed to work, but the Can't mount /cache or anything else seems to be the main culprit.

I tried to mount via adb and it doesn't work. for example tried to mount /bootdata it complained that it couldn't find /etc/fstab

I can see folders, not sure why I can't mount... Any suggestions would be much appreciated.
[Nook HD, HD+ Android Development] digixmax:
I had the same or similar problem a couple of times when I was still running CM off SD card -- it seemed that some part of EMMC ROM image in /system or /data got overwritten by accident (e.g., flashing by mistake an EMMC-based CM image instead of an SD-based image) or by some unknown error. Fortunately (as an extreme precaution) I had done a full backup of the stock ROM image using CWM recovery and was able to revert to stock without much difficulty.

I'd suggest that you try reverting to stock by using the "eight failed boots" method: with the Nook in the power-off state, power it on, then as soon as the boot screen appears hold down the power button until it powers off; do this 8 times, and (assuming stock recovery has not been replaced with CWM recovery) the Nook should go into stock recovery to revert to factory-fresh state (beware that all user-downloaded apps & contents would be lost).

If the "eight failed boots" method does not work then you should try reflashing the stock ROM -- see item #6 of [MENTION=349198]leapinlar[/MENTION]'s post http://xdaforums.com/showpost.php?p=35811322&postcount=1.
[Nook HD, HD+ Android Development] panamamike:
Is there a way for me to validate what's happened to my Nook? I was able to briefly reboot into the SD image. Everything was working fine except for those dreaded, X stopped working. I think what's happened is that too many things are installed on the SD card causing it to go slow or something. maybe this is affecting to boot sequence.

I tried to load to stock, but it woudln't. It would go as far as the "nook" screen. I can use adb to see some of the folders but not sure what I should try to get it back up and running. I tried to su, but that command isn't available.

I'm in as root, don't know if that's su by default. I'm unable to mount. I can see devices. 0123456789ABCDEF and

Recovery.

Not sure what I can do from here.

Regards,

Mike
[Nook HD, HD+ Android Development] digixmax:
I think it's more likely due to the SD card you're using; I'd suggest you try a different card.

Did you flash the stock ROM NookHD-factory-2.1.0-plain-stock.zip file referenced in [MENTION=349198]leapinlar[/MENTION]'s post at http://xdaforums.com/showpost.php?p=35811322&postcount=1?

Note that to flash the stock ROM zip file you should use an older version of (SD-based) CWM recovery like v6.0.2.8 linked at the end of that post.
[Nook HD, HD+ Android Development] Kubombelar:
thanks for this. Just wanted to ask, what is the difference in speed, overall performance of running the ROM from an SD card in comparison to the EMMC? Also what type sd card do you recommend for running the ROM. Thanks
[Nook HD, HD+ Android Development] leapinlar:
Always use a SanDisk class 4. Some other cards will give you i/o errors and run slower. With the HD/HD+ there always is a slight slowdown running from SD, but not significant if you use the recommended SD.
[Nook HD, HD+ Android Development] Kubombelar:
thanks man. minimum 4GB?
[Nook HD, HD+ Android Development] leapinlar:
Yes, but the bigger the better as it uses it for media storage too.
[Nook HD, HD+ Android Development] Prof24:
Couple of questions, upon seeing this is an SD card install:

Used verygreen's CWM 7.1 to dual boot Nook HD+ a few months ago. Will 7.1 /does 7.1 work for installing CM 11?

Along that same line, I believe there winds up being an "open slot" for a second rom on the CWM dual boot menu screen. Can I install the KitKat rom in that slot, or should I just wipe everything and follow bokoban's instructions?

Thanks ahead of time!
[Nook HD, HD+ Android Development] leapinlar:
No to both. Start fresh.
[Nook HD, HD+ Android Development] Prof24:
Thanks - suspected as much...sorry for stupid dual post too, clicked something wrong in sending.
[Nook HD, HD+ Android Development] jamdev12:
Thank you for this nice gift. Easy to setup and get going on my Nook HD+. Running on class 4 sdcard, but will try my regular class 10 and my sandisk class 10 and see the difference. EMMC install would awesome to try, but can wait for a little longer.

Are Sandisk Class 4s still the best for this? Should I even try a 16gb UHS-1?
[Nook HD, HD+ Android Development] leapinlar:
Yes the SanDisk class 4 are best, but many have had good luck with the UHS-1.
[Nook HD, HD+ Android Development] Nuor60:
My personal experience is I seem to have better speeds with my class 10 Sandisk than my class 4 Sandisk; Both benchmark tests and perceived responsiveness of tablet.
[Nook HD, HD+ Android Development] YevOmega:
Ok. Thanks. Now the question is, will this run better than eMMC 10.1.3? Even though it's been running well for you leap, my Nook has still lagged on 10.1.3. Changing the scheduler to deadline helped and I use Greenify to hibernate most of the apps on it, and I have some eMMC space left, so it's not 'cause of that.
[Nook HD, HD+ Android Development] lorddunlow:
I'm running out of SD cards with much capacity right now. Would it be possible to make an image of my current SD (used for bokbokan hybrid CM10.1 install) and then wipe it and flash this onto that card. Then, if I want to just go back to how things are now, I could flash that image to restore the card? I would think it would work, but I don't want to screw my card up.

I'm getting another 32gb card, but I'm impatient to try this.
[Nook HD, HD+ Android Development] leapinlar:
That should work.
[Nook HD, HD+ Android Development] jamdev12:
I've tried both a Samsung class 4 and a Sony class 10. I see no improvement in terms of speed. To me it seems either:

1. The CM build is simulating rendering. OMAP never released the driver source for their CPU/GPU.

2. The GPU can't handle the resolution.

Nothing against this build. Just that I have a Gnex with a OMAP 4460 and a slower VX540 GPU and running KK after the graphic glitches were fixed runs super smooth. Don't know if Linaro is the culprit here, but I feel this hardware should be able to run faster than either, the BN builds, or these MODS.

Not sure how to do this, I tried sideloading the CWM. Says it loaded, however when I reboot I still have the newer version of CWM. I'm unable to load from zip since none of the drives can be mounted. Is there a way to load CWM?
[Nook HD, HD+ Android Development] digixmax:
Use the content of the file NookHDplus-bootable-CWM-6028-for-stock-BOOTFILES-r4-(05.15.13).rar to create a bootable SD card (make sure that MLO is the first file you copy to a reformatted SD card (for more elaboration see steps #1 & #3 of my post at http://xdaforums.com/showpost.php?p=51043572&postcount=1)), next copy to the SD card your choice of stock ROM zip file downloaded from the link in item #6 of leapinlar's post, then reboot to SD to enter SD-based recovery to flash the stock ROM zip file.
[Nook HD, HD+ Android Development] panamamike:
I was able to get the CWM boot working. Now it won't let me flash the ROM due to the e: Can't mount /cache or /sdcard error. Any thoughts?
[Nook HD, HD+ Android Development] digixmax:
Try format/wipe the /cache partition (

warning

: do

not

ever format any partition other than /cache, /data, or /system).
[Nook HD, HD+ Android Development] panamamike:
I actually tried formatting the cache earlier. I hadn't tried wipe. Still no luck with the can't mount.
[Nook HD, HD+ Android Development] digixmax:
"wipe" is synonymous with "format".

Which version of CWM are you using?
[Nook HD, HD+ Android Development] panamamike:
Thanks for helping, I appreciate your effort.

I'm using v6.0.2.8, this is what you recommended installing earlier.

As far as wipe vs format. There are two options one in mounts and storage menu there is a format cache option.

In the main menu area there's a wipe cache partition option.
[Nook HD, HD+ Android Development] digixmax:
Did you format the SD card as a Primary FAT32 partition with partition ID type 0x0C FAT32 LBA?

You might also want to try a different SD card if available.

[Nook HD, HD+ Android Development] tossici:
I was looking for a quick way to update my nook HD without writing to the emmc. This was perfect. Instructions were great (easy to follow). I found a link to the kitkat gapps download from the CM wiki and I'm up and running off the SD card already. Fast and smooth, and I can download some apps that were no longer available on the stock rom. Thanks for all of your work, much appreciated!
[Nook HD, HD+ Android Development] ieatabiscuit:
Glad that worked out for you, but I'm curious, why not write it to the emmc? Finding a hummingbird or ovation with any warranty to void isn't an issue at this point, there's an extremely stable MM release available that way, and the responsiveness would be faster. Don't get me wrong, there's absolutely no harm in just trying to be safe, but I can't help but be curious.
[Nook HD, HD+ Android Development] ST Dog:
Larger storage? I can install on a 32GB SD card v/s the 8 or 16GB emmc (and still use the internal data partition too).

I can easily make a image of the SD card as a backup. No need for TWRP or other solutions.

I can plug the SD card into another device and it rolls on like nothing changed (unless I was using internal storage).

I'l love to see the SD install updated for MM.
[Nook HD, HD+ Android Development] ieatabiscuit:
I can see your point, the storage being right there in front of you instead of on a "separate" partition. TWRP is handy in that you can use F2FS instead of ext4 though. As for a MM install for an SD card, that would be tricky. They changed SOOO much about how the partitions are set up, and added external storage adoption, pulling your larger storage option into the native setup (I use it on my daughter's HD, though it's useless on my HD+ saddly). I don't think the newer setup would do well with the primary and secondary storage reversed. Also, if you adopt the external storage it encrypts the SD card so you can NOT plug it into other devices, in face unplugging it after the bulk of the /data partition is moved to it makes bad things happen. I was just curious because I had to make that decision back when I got my hummingbird, and later ovation. I chose to take the full plunge, curious of the use of taking the SC option that I ignored back then.
[Nook HD, HD+ Android Development] tossici:
I just wanted to get up and running quickly. I always ran from the SD card on my nook color so it was just more familiar for me to get going this way. I would like to read through a few threads before installing to emmc. I got my nook HD from groupon for next to nothing. It came with a big sticker on the back that said demo unit: not for resale not for inventory :)
[Nook HD, HD+ Android Development] ST Dog:
It would just treat that partition like the external card. Just don't select adopted storage (or better still, disable it in the build).

I'm sure a TWRP was made for the SD install, and if not could be.

I just don't have the time to figure it all out. I tried to get some help from the originators of the hummingbird/ovation SD installs, but no responses.

Which is why I finall indtalled to EMMC to get current with KK and prep for MM.
[Nook HD, HD+ Android Development] ieatabiscuit:
The adopted storage feature is pointless unless you have maybe an 8gb device, or less. But you're right, just pick the portable storage choice. The MM build that amaces had going is pretty amazing. When you get the time, you should definitely look into it. If you do screen casting his aosp build is the way to go. If you just love CM, then he has a CM build that's nice too. I use them as daily drivers aosp on my ovation, and CM on my daughters hummingbird. Only downside some people see is that you are limited to a small GApps option. I use a small one anyway, so it does not affect me at all.
