Performance issues are a real shame. I'm also on class 10 and hybrid is working pretty great for me. I really want to be able to use Play Books now that they allow for uploading of your own books... Not sure what to do... If OP came out with EMMC install for this build (love the extra features) I might try that out...

Thanks anyway for checking it out for me, really appreciate it.
[Nook HD, HD+ Android Development] bokbokan:
can you post a logcat so that I can look at the issue?
[Nook HD, HD+ Android Development] SouthernGeorge:
I've been having the same issue but I've been using leapinlars hybrid setup, so I don't think its isolated to your system.

Also, it worked before Google sent out the update that allowed for personal PDFs and epubs.

Let me know if that works and is what you're looking for from me. Thanks!

Well.. this is new. installed google play music, booted it up and got a notification to add a backup account. Tapped it, and immediately rebooted into EMMC install, and now it wouldnt boot from SD install.

Re-flashing now. :/
[Nook HD, HD+ Android Development] mikelav456:
FWIW I just tested it based on your comment and I did not have this issue on the Hybrid build. Just downloaded app, ran it, started pinning music, playing music, etc... All running great, and actually looks wonderful on this screen! Playa Magazines is also working perfectly. Will try Play Movies and TV later. If Play Books was working properly without crashing I would be in heaven. I love everything else about the ROM and my setup. Hybrid is running smooth, additional features are wonderful.... Hope bokbokan can come up with a fix for us based on the logcat!

Edit: Just tried Play Movies & TV. Same problem as I had on lepinar's Hybrid build. It downloads, opens and runs fine, but does not sync with my account at all. It shows in the sync menu under settings and I have it checked off, but it doesn't actually sync. My movies and TV shows don't show up at all. Not a deal breaker like Books is for me, but still pretty annoying that I can't access my stuff. Both Play Movies & TV and Play Books were functioning 100% fine on the stock B&N rom so I'm not sure why they're not working on an AOSP-based ROM....

Edit 2: Aaaaaaaand now I have an OS problem. I had this problem with lepinar's Hybrid buid as well, as well... Every time I try to unlock the device, it flashes unlocked for a split second, then relocks the device. There is nothing I can do to actually get it to stay unlocked. I try to use the tablet ui notification drawer shortcut to get into settings, but it relocks again there too. I'm forced to reboot the tablet. I think it's weird this happened after I installed Play Movies & TV. I wonder if that's why it happened there too. Maybe something about it having a broken sync???

Edit 3: After reboot, I uninstalled the app and now it's not letting me unlock it again. App may have caused the problem, but uninstalling did not solve it. Bokbokan, any plans to make a build for EMMC?
[Nook HD, HD+ Android Development] bokbokan:
If you are using a cover and opening it did not wake the device up, do not wake it up using the home button or it will not unlock. Close the cover and open it again. Do it until the device wakes up on its own by opening the cover. After this, unlock screen should now work.
[Nook HD, HD+ Android Development] mikelav456:
The problem I was having was that the screen was on the whole time, but the sliding to unlock wouldn't help, it would lock the screen, but keep it on... FWIW, since uninstalling Play Movies, while it didn't work right away, after a reboot, I don't seem to be having the unlock problem anymore.

Edit: Just saw your request on Drive, one sec and I'll give you access.

Thanks for all your work!
[Nook HD, HD+ Android Development] Delvien:
I get this problem too, I also had this issue with the emmc build as well. By chance, do you have the magnetic cover that sleeps the device? (if you do, and that's the common denominator from what I can gather)
[Nook HD, HD+ Android Development] mikelav456:
Yeah I do and that's what bokbokan seems to think it is too...
[Nook HD, HD+ Android Development] bokbokan:
can you try changing this property from build.prop

dalvik.vm.heapgrowthlimit=48m

to

dalvik.vm.heapgrowthlimit=96m

This may probably solve the book problem.
[Nook HD, HD+ Android Development] mikelav456:
Wow! That seems to have a fixed! Thank you!

I did get one force close but I was messing with it a lot, highlighting words, and swiping around in random directions. Normal use seems mostly stable. Epubs resize each page on a page turn, but I can live with that.

Thank you so much!!!

Now, any ideas about the Play Movies & TV app?
[Nook HD, HD+ Android Development] bokbokan:
Send me logcats and I'll try to check on them
[Nook HD, HD+ Android Development] mikelav456:
I would, but would logcats help? It's not crashing, it's just not syncing at all. When would I even capture the logcat? After download and when I open the app???
[Nook HD, HD+ Android Development] bokbokan:
Start capture when you start the app and up to closing it.
[Nook HD, HD+ Android Development] mikelav456:
Done. Shared it with you on Drive again.
[Nook HD, HD+ Android Development] Delvien:
Any suggestions on how to fix the lag? As an example, I tap chrome, and it takes 2-3 minutes for me to be able to do anything, it sits there loading chrome the entire time.

Edit: took the plunge, so far hybrid is working fine.
[Nook HD, HD+ Android Development] verygreen:
Does this come with the same uboot source as Nook HD references, or would you make us a new source drop (or perhaps even a github repo?)
[Nook HD, HD+ Android Development] bokbokan:
A new source drop in the OP.
[Nook HD, HD+ Android Development] BillBong:
I've installed the hybrid version and it's running nicely.

One thing I'm experiencing that I can't see anyone else has mentioned is with the keyboard selection. I've installed TouchPal which I always tend to use, but the system keeps defaulting back to the Android AOSP one every so often. I go back to system settings each time to change it which works fine until next time I use the keyboard and it's back to AOSP.

Any ideas why this is happening
[Nook HD, HD+ Android Development] mikelav456:
Can we just dirty flash this over existing ROM? Do we need to reflash gapps?

BTW, Play Movies and TV issue solved itself. Maybe just took a while to sync?
[Nook HD, HD+ Android Development] bokbokan:
yes, no need to reflash gapps. New update instructions added in the OP.
[Nook HD, HD+ Android Development] mikelav456:
Hi bokbokan,

Having major Play Store issues. It crashes very often, even when not messing with it. Also crashes often when I try to add the "Play Store - My Library" widget. The widget adds but crashes the play store. Furthermore, and a bit more frustrating, I can't get my Play Magazines to display in the Play Store - My Library widget no matter what I try. They don't even show in the when I choose for only the magazines to display alone. I have attached two logcat links below.

The first one the Play Store crashes randomly:

and second one I try adding the Play Store widget to display magazine covers, it doesn't work, I get rid of the empty widget, try to add it again, Play Store crashed:

SD storage?

For me, cm10.1 hybrid works well so far. I also implemented this change at

http://www.androidpolice.com/2011/0...-200-with-a-simple-tweak-hands-on-benchmarks/

to make the SD card speed faster (not sure if it works).

Now I have some newb questions involving this hybrid build.

1. I have an external microsd of 32gb. However, i cannot access the full partition unless I have it connected with the device. However, one problem with this is that the transfer speed via the device (instead of directly from the sd card) is very very slow. I was hoping the above sd cache method might alleviate this problem, but it doesn't seem so, and it also creates a problem, 2:

2. I noticed that when I try to copy files above 2 gb or so to the sd from the device, the device spits out an error in the middle of the transfer that it cannot connect to the device, and fails. This happens every time. Is there a way to fix this, or should I just assume that big files cannot be transferred?

3. I am just curious. I am thinking that since the cyanogenmod we have works quite well, why keep the actual nook os inside the nook itself and have another os installed to the sd and run off that? What about just installing the cyanogenmod inside the hd+ and run off that? Is there a disadvantage to this?

Thanks to your attention into my questions!

Really enjoying the hd+!

[Nook HD, HD+ Android Development] Taosaur:
Regarding #1 and #2, it sounds like you're talking about transferring data from a computer via a USB connection. If so, a lot of the problem is that newer Android devices can only connect to PCs using Media Transfer Protocol (MTP), which is ridiculously slow and buggy for simple data transfers. I've just stopped plugging my Android devices into my PC altogether. If I'm putting a lot of data on a single-partition SD card, I plug the card into the PC directly. Most of the time, though, I just use a file manager in Android (ES File Explorer is my favorite right now) to grab files over my wireless network. It's often faster than USB transfers.

For #3, there is an internal (EMMC) install thread. If you don't care about keeping the stock OS, it's definitely simpler not to dual boot. A lot of people like to take baby steps in replacing the original software, and some people are attached to aspects of the Nook ecosystem or HD+ software--I like the native magazine reader. I was running leapinlar's hybrid dual boot up until B&N added Google Play, then decided to give vanilla stock a try again and found it good enough, especially during a busy stint where I needed my tablet to just be a tablet rather than a hobby. I wouldn't go back to dual booting, but at some point I probably will migrate to CM10.1 on EMMC. I just wish Nook for Android or Google Play Magazines worked as well as the native HD+ magazine reader.
[Nook HD, HD+ Android Development] gomavs123:
Hey Taosaur, thanks for your reply.

Unfortunately, wifi at my house is quite slow and therefore transfer via wifi of big files such as mkvs (~15gb) will take simply too long.

I have actually tried connecting the SD card directly, but for some reason, the computer recognizes the boot partition only and not the card partition, which is less than 100mb.

Thanks for the info about EMMC. Thats what some users were commenting- I was wondering what EMMC meant. I will do some searching around to find a good EMMC thread. Meanwhile, can you point me to the right direction by directing me to one?

thanks in advance.
[Nook HD, HD+ Android Development] leapinlar:

[Nook HD, HD+ Android Development] mikelav456:
For anyone who has tried both EMMC and the Hybrid here (with a class 10 sandisk), which is snappier and runs better? Hybrid has been ok, but a bit laggy.

Also, I'm guessing the answer is no, but can I use the actual ROM from this thread and the recovery from the EMMC thread to install on EMMC? I like the SGT7 features a lot and would love to keep them!
[Nook HD, HD+ Android Development] leapinlar:
You are right, the answer is no. The ROM zip needs to be specifically taylored to run on emmc and the ROMs here are not.

And in general, running verygreen's ROMs, emmc is better than his ROM on my Hybrid SD, especially on a Class 10 SD.

Thanks leapinlar, really appreciate the feedback. Any way we can get bokbokan to work with verygreen to add these extra features into the EMMC build????
[Nook HD, HD+ Android Development] leapinlar:
The answer is to get bokbokan to develop an emmc version of his ROM. But I know for a fact he has other higher priority activities going on now.

Hello,

I just noticed that there was an update today that address some boot issues. I have been having some problems with my device not booting into CM10.1 as well as frequent random reboots. I was just wondering if these issues are the ones addressed with the new version?

Also, if these are the issues addressed, can i just download the new zip and run from recovery to update (i apologize if this is answered in the line below the update, im not very well versed in the terminology).

Many thanks,

David

Hi bokbokan,

The screen gets stuck at cyanoboot screen after replacing ramdisk.hybrid on v1.
[Nook HD, HD+ Android Development] bokbokan:
If you are using pure sd install, then you can simply do that.

This fixed the boot issue but not sure of the random reboots since I'm not encountering any reboot. Try changing your sd card.
[Nook HD, HD+ Android Development] bokbokan:
Have you tried turning off and on again? Is is always stopping at the cyanoboot screen?
[Nook HD, HD+ Android Development] Snakemanc6:
Im not using the pure sd install, im on the hybrid.I may try it with a spare class 4 16gb card i have laying around. I was really hoping to be able to use my 64gb class 10, but i new going in that the Sandisk class 4 was the preferred solution.

For some reason i just cant wrap my head around the hybrid installs, and various methods used with the Nook. Debating selling the Nook due to the restarts and issues staying in/getting to CM10.1.

Ill give the 16gb card a try later tonight probably.

I am getting random reboots...any ideas? It loads fine and I am able to maybe get 5 minutes from doing stuff like changing settings for the most part.

[Nook HD, HD+ Android Development] gomavs123:
Thanks for the help. I will look into the EMMC thread as leapinlar pointed out.

However, I am still in need for somebody to help me out with my first question in the post involving the two different partitions in the SD card.

taosaur pointed out the problem with my current setting is due to me using the MTP protocol method,

transferring my files via device connected to the computer via usb instead of the SD card itself. However, I have to resort to this method because

just inserting in the SD card separately to the computer results in the root partition(100mb) and NOT the sd partition that is ~27GB being detected.

And just like taosaur pointed out, the usb transfer method is awfully slow and most of the time just doesn't transfer large files.

Do I have to set something up in the initial flashing stages so that there is only one partition instead of two, or some method for the pc to pick up the Sd portion? Any help will be appreciated.

You guys have been great in helping me go through a satisfactory and successful transition to android from the overpriced ipad environment I was in before ;)
[Nook HD, HD+ Android Development] leapinlar:
No, it needs those separate partitions in order to operate. And there is no way for the PC to see the second partition while it is in the PC. You must use the cable or you can use wifi transfer with ES File Manager or Wifi File Explorer.
[Nook HD, HD+ Android Development] Taosaur:
One major reason I've given up on hybrid and SD installs is the difficulty of getting media on the card. As leap said, there's no way to point Windows to any but the first partition, and as you've discovered MTP transfers are a pain and often just don't work. If you end up doing a EMMC install, you can reformat your SD card and load the files directly. The other option is to manage your media files with a library/player type program, "syncing" rather than doing direct file transfers. It's what MTP was made for and seems to be less buggy, but I can't recommend any program in particular for giant MKV files.

Silly question, easy way to remove this hybrid if needed?

Hello,

This might sound like a silly question but if I want to remove the hybrid version of this install so that I can go back to an SD version a few weeks down the road, do I need to do a system restore or is there just a couple of files I can remove from the stock BN rom?

Thank you and keep up the great work!

---------- Post added at 10:59 AM ---------- Previous post was at 10:43 AM ----------

Hello,

I had been using the Pure SD version and just switched to Hybrid today. Upon boot back into Stock BN ROM after some time in CM10.1, an app GMD Gesture Control is reporting errors that could not gain root access. But seems that the SU app and another memory management app are working correctly, and this app is in the allowed root access(removed and readded but no luck nor does it re-request root from SU), not sure if anyone might have seen this.

Thanks
[Nook HD, HD+ Android Development] leapinlar:
The answer to the first question is to boot to your rooted stock and go to /data and delete the cm_data folder. That will remove your hybrid files from internal memory. Then re-burn your SD back to Pure SD.

On the second question, I doubt your stock root issue has anything to do with running hybrid. Have you tried uninstalling and re-installing the app?

I just want to add my request for bokoban to port this build to EMMC. I'm finding vanilla CM10.1 annoying in a lot of ways, though that may change once I take the time to dig in and set it up to my liking.

The file structure and handling of external storage is a hot mess--I'd swear Google is actively sabotaging SD storage in light of their conclusion that multiple drives hurt consumers' wittle bwains.

Quick question. I am planning on doing the Hybrid option soon.

Do I need to root my HD+ before starting? Or is that taken care of in the procedure? I saw comments about the Nook not booting from the SD card, requiring you to download an app that changes the OS. Is this still necessary?
[Nook HD, HD+ Android Development] leapinlar:
You do not need to root stock before starting. The comments were that some particular HD+ devices are hard to get to boot to SD. If you have one of those, sometimes it helps to root stock and add an app (quick boot) which requires root and have it help you boot to SD. If your device boots to SD easily, which most do, then you do not need to root stock.

With gapps, the installer is generic. So it gets the info for where /system is from the recovery itself. So if using a recovery for emmc, it will put it on emmc /system, if using a recovery for SD, it will put it on SD /system.
