[Q] Dual Boot Nook HD+ with Rom Selection at startup? - Nook HD, HD+ Q&A, Help & Troubleshooting

Hello,
I have been doing some searching on the forums for the past few days and I have not come across this question or if the process exists.
I was wondering if it was possible to have a dual boot of the Stock Rom and Cyanogen where you would be given the option of selecting which one you wanted to boot into when powering on the Nook HD+ ?
I've seen some posts about having both and having to pull the SD card during the boot process to have the nook boot stock. I also recall reading about a method of having both the Stock and CM both loaded on the internal memory but i believe this was abandoned.
Mostly what I am looking for is a simple method to have the both without needing to pull the card.
Thanks in advance to any recommendations or suggestions.
EDIT: it looks like a similar question was asked that I missed:

It is possible to set up a boot menu to leave the card in and let you choose from a menu, but verygreen's stock SD does not use that. - Reply

Is there any links or tutorials showing how to do this?

Yes, this is possible if you have stock on internal memory and CM on SD. If you use bokbokan's version of CM10.1 or CM10.2 on SD it comes with a boot menu that allows you to choose. If you are using verygreen's version of CM10.1 or CM10.2 on SD, his does not have that menu. But if you look at my HD/HD+ CWM thread linked in my signature, I have made a zip to add that menu to his version. See item 9.

[Q] SD Card installation [CM10] - Nook HD

I bought a Nook HD and would like to try out CM10 via an SD card installation. I've read through a lot the android developer forum topics, but I am confused as to what the SD card installation actually does.
I am following the steps for "CM10 sdcard Installer" from this thread: http://forum.xda-developers.com/showthread.php?t=2063968
I used PlugPBX to format and write the IMG file to my SD card.
Before I plug it into my Nook HD, I like to know what it means in step 5: 'Wait for it to finish installation." Does this mean the package from the SD card will install CM10 to the internal memory? Or does that just set it up on the SD card? After doing it this way, am I still able to remove the SD card and reboot to go back to the stock Nook OS?
Sorry, for the noob questions, but I didn't want to do anything that might not be easily reversible, possibly void the warrant, or make it so I can't return the Nook HD within B&N's 14 day window.
Thanks in advance for the help!

What that is referring to is the SD needs to make more changes to prepare the SD for installing CM. It creates more partitions on the SD and formats them so a ROM can be installed to it later. No changes are being made to your internal memory or stock setup. Then you still need to install the actual CM ROM. And at any time, when powered off, you can remove the SD and boot to stock as if nothing were ever done to it.

Thanks for the reply!
To flash the ROM I just put cm-10-20130101-UNOFFICIAL-hummingbird.zip from the link in the OP on the root of the SD card and install via the CM recovery, right?
Then do I need to flash the Gapps separately?
The order doesn't matter and I don't need to wipe anything in between right?
The order does matter, ROM first and gapps second. But you don't have to wipe anything.
And why are you choosing that old CM10 ROM from January? Use the latest CM10.1 ROM, you will be happier. And if you do, you will need a newer gapps too. Gapps-20130301-jb-signed.zip. Get it from goo.im.
And no, you do not put the CM ROM on the root partition, since recovery will not see it there. Follow the directions in the OP to get it where recovery can see it.

[Q][NookHD+] CM10.1 native emmc install

Hi, guys, I am really new to my Nook HD+ coz I received it 2 days ago.
After reading lots of posts, I wanna try the CM10.1 native emmc which I used with other pad.
May I ask after installing it by the method given by verygreen(http://forum.xda-developers.com/showthread.php?t=2263553), is it possible to reset it to the original Nook system with the 8-restart method? Coz I note verygreen says "Note, this version totally overwrites your ROM, so back up everything important before proceeding".
Thanks very much!
If you replace the stock recovery with one of his recoveries (CWM or TWRP), the 8 failed restart no longer works. If you only install his ROM and not the recovery, the 8 failed restart still works.
But if you use his CWM SD to do a nandroid backup before you install his ROM, you can restore that one later so you get stock back.

No, don't use early4. If you want to install the CM to emmc, you must use the CWM that he has in the emmc thread (early 2.1). It should unzip to 1GB and can be burned to a 1GB or larger SD. Don't confuse it with the other cwm zip (that he calls CWM recovery) that is meant for flashing CWM to emmc.

I installed verygreen's CM10.1 native emmc install without replacing the internal recovery. It works well but I found sth wrong.
1. Sometimes the wallpaper cannot be full screen after changing from landscape mode to portrait mode.
2. For the lock screen sider shortcut, I cannot do any modification in the setting and for the phone and sms icon, when I move to them, it says error.

[Q] I have a rooted Nook HD and its running extremely slow

Hi All,
I have a Nook HD that I have rooted and was running on a SDcard CM10.1 install. After Barnes and Noble gave the device the option to use the play store, I returned to the stock installation because even on a Sandisk Class 4 SD card the CM10.1 was a little laggy for my tastes. However, the device feels even laggier now than it did on CM10.1. Things like the settings drop down often take 5-10 seconds to pop up. The brightness slider doesn't follow the finger at all and lags behind where I tell it to go. In addition, auto rotating causes some ugly behavior where the wallpaper will black out part of the screen and then fill in a second or two later.
I never had any of these problems before I started using the CM10.1 install when I was just running the device stock-rooted. I'm not sure what to do to fix this, other than a factory reset which would wipe all my apps and books and things and hope for the best. Any advice guys?
You did not say which HD you were running, 8GB or 16GB, and you did not say whether you were running the Hybrid CM10.1. In any case you are probably running out of space in your internal memory. Look at sdcard and see how much free space you have. If it is less than 3GB, delete or move some of your media files from there. See if that helps.

I've got the 16 GB edition, and I've returned to the stock OS. (No more CM). As for storage, I've got 53% available of the internal storage and 94% available on my SD card so I dopn't think that's the problem.

The reason I was asking about Hybrid is just getting rid of the SD does not remove the internal Hybrid files and they can take up a lot of unnecessary internal space. You need to remove those manually.

Ah, no I was simply running the SD Card installation of 10.1. I wasn't comfortable mucking around in the actual installation files, although I was interested in the hybrid install. The main reason I went back to stock was that CM10.1 was running pretty slow from the sd card and with the play store now available to anyone, I figured I had no reason to worry about flashing g-apps and all that jazz.
EMMC install, multi user, and adb
1] When I first got my Nook HD+ ( a Mother's day present for my wife) I installed CM 10.1 on a Kingston 16 Gb SD card and it was very slow to the the point of being unusable. So I installed via the EMMC method and now it runs really good. CM turns a mostly lame product into a totally awesome one.... Thanks verygreen. Thanks Thanks Thanks.
2] CM is the only way I have found to get true multi-user capability. The stock Android with any launcher I tried did not switch accounts(email accounts were for the other user)
3] One program (MightyText) installed perfectly on my wife's account, but Google Play reported that it is not compatible with my device when I tried to install it on my account. I am guessing this is not specific to CM or the Nook.
4] I enabled ADB wireless and I am able to ping my tablet, but both Windows 7 and Ubuntu report device offline wehn I "adb devices"
5] CM 10.1 runs sooo great for being an early build. I experience a little touchiness with the wallpaper and an occasional wallpaper stopped responding. Thanks verygreen. Thanks Thanks Thanks.
6] I really want to run TWRP recovery (installed without SD card) but no luck yet. I'm not sure i'm doing it right. I copied the .zip to my boot SD, selected install from the Clockworkod recovery menu, and it reported installed. But when I reboot without the SD card, it boots back into CM 10.1. How does recovery know how to install a recovery to the recovery location?
BTW Bonehead Experience:
Don't install the wrong GAPPS. GAPPS for CM10 (not 10.1) goes into a forever loop reporting the Setup Wizard stopped

There are two ways to boot to emmc installed TWRP.
First is to hold the power and n keys together when booting.
The second is to go to settings, about tablet and tap the build number several times. That will enable developer options. Go to that and check off Advanced reboot. Then when you use the power off menu it adds the recovery option to the reboot menu.

Hey thanks a bunch this works. Actually I think it worked all along. When I hold Nook+power, after the Nook screen, I get a black screen. I then tap the power button and then it reboots into TWRP. Is this normal to to have to tap the power button?
Also, I have tried the Quick Boot app (Quick Boot -> Recovery) but it just reboots. Anyway, I'll try the Advanced reboot stuff next maybe that will fix reboot apps.

I use CWM so don't know about TWRP and tapping power. But I did have that happen on an old CWM SD. Just had to touch power and it appeared after the blank screen.
Quick boot recovery has never worked.

[Q] Confused about Nook HD+ CM10 installaiton methods

I wondered if anyone could help me regarding the practical differences between the three types of CM10 install (EMMC, hybrid and SD card) - as in, does each method vary in speed, stability etc? I'd like to know which is the 'definitive' method for stable long, term CM10 use (as I was running cm-10-20130220-UNOFFICIAL-ovation using hybrid method, which was running perfectly for weeks, until one day it froze while I was playing a game, and now won't boot into CM10).
I'd also like to still be able to restore the original Nook OS in case I ever need to send it back under warranty; is this possible with an EMMC CM10 install?
Thanks in advance, guys.

I went ahead and installed the EMMC method. Runs smoother for me than either of the SD card options.
once you have recovery installed on your Nook HD+ you can make a nandroid backup and revert back to nook OS any time you want.

There is not one guide that pulls it all together. Verygreen's native emmc guide tells you how to make his bootable CWM SD and flash the ROM, but is kind of sketchy on how to backup stock and optionally install the internal recovery.
I suggest you go to my HD/HD+ CWM guide linked in my signature and follow the below steps:
1. Make a bootable CWM SD per my new procedure in section 1a.
2. Boot to the new CWM SD and backup your stock ROM per item 1d.
3. Use the CWM to flash verygreen's latest emmc version of CM10.1 from his native emmc thread.
4. Use CWM to flash gapps-jb-20130301-signed.zip downloaded from goo.im
5. Use the CWM to 'wipe data/factory reset'
6. If you want to put CWM on internal memory, flash my version of internal CWM per item 5 of my thread. (Optional)
7. Remove the SD and boot to your new CM10.1 ROM and register and set it up.
8. If you want to go back to original stock, use CWM to restore your original backup.

"No sd-ext found. Skipping backup of sd-ext."
Is this a problem, and should I be concerned?

Nook HD+: bootable SD after 2.1.1?

I have a new Nook HD+ on the way, I plan to register it and then install CM 10.1, but I'm concerned I saw in another thread that someone wasn't able to boot off an SD and the update automatically installed. Can anyone confirm they were able to still boot of an SD card after installing 2.1.1?
I was able to boot off a Transcend Class 10 SD card after installing the 2.1.1 update.
Some HD/HD+ units reportedly have difficulty booting off SD card, see http://forum.xda-developers.com/showthread.php?t=2288688. The problem has nothing do with the stock ROM, new or old.
Ok, thanks. Should have it today and will go ahead as planned. Just concerned me it was a brand new update and I'd only seen the negative response, but it sounds like it should be good.

My HD+ would not boot with a 4gb card or a 2gb card, I tried it at least 10 times apiece, however I did get it to boot with a SanDisk TransFlash 256 MB with just the boot image files and CWM.
It boots to the 256MB card first try everytime. So as soon as CWM loads I swapped the 256 for the 2gb and did a stock backup, rooted and installed CM.

but i forgot to copy universal root onto my sd card..............so can i root my nook later after installing cyanogenmod?

I am tempted to dispute this. I had a brand-new HD+ with stock firmware v2.0.4 which consistently (and always at first attempt) booted from sd card (Kingston 4GB, cl 4).
After upgrading to stock firmware v2.1.1, but with no other changes, it wouldn't boot once in 50+ attempts. The sd card was unchanged, the HD+ hardware was the same, so this behaviour would seem to point to the firmware change as the culprit, doesn't it?

It does, but booting is controlled by the hardware chip firmware. There is no way for b&n to change that remotely.
A way to test your theory is to do an 8 failed boot with stock recovery installed and go back to 2.0.4. Then see if your booting trouble goes away.
Edit: If that is really the case, the solution is to revert to 2.0.4 and immediately upgrade to CM. Then it should boot SDs ok.

I am tempted to dispute this. I had a brand-new HD+ with stock firmware v2.0.4 which consistently (and always at first attempt) booted from sd card (Kingston 4GB, cl 4).
After upgrading to stock firmware v2.1.1, but with no other changes, it wouldn't boot once in 50+ attempts. The sd card was unchanged, the HD+ hardware was the same, so this behaviour would seem to point to the firmware change as the culprit, doesn't it?

My HD+, which originally came with 2.0.4 and got immediately auto-updated to 2.1.0 and then later to 2.1.1, (luckily) has not had any problem booting off SD.
The boot-device selection process is controlled by the hardware configuration and bootstrap code in ROM (this is the device's real ROM, as opposed to the Android OS software that is commonly but incorrectly referred to as "ROM"); see http://omappedia.org/wiki/Bootloader_Project for an overview of the boot process, and more gory details can be found in http://www.ti.com/lit/ug/swpu270s/swpu270s.pdf.
Have you re-checked "bootability" of the boot partition of your SD card, or tried a freshly burned SD boot image? I have had a few instances of Recovery or ROM SD cards rendered un-bootable after the stock ROM created files/folders on them.

As I wrote in my first post, the sd card (which booted properly with v2.0.4) was unchanged. I deleted all stuff the HD+ had put on it (a bunch of empty directories, if I recall correctly) and it had only the 5 CWM boot files and 2 zips I wanted to install. To the best of my knowledge the sd card was unchanged.
Never mind, it's probably one of those things...

As he said earlier though, the fact that 2.1.1 wrote to it at all may have done something to the SD.
