[Q] Does the HD+ sd boot require rooting?

(caveat: I am new to android and have done searches within xda and general online searches and while I think I have the answer, I'd love input from those who know for certain).
As the title states: does the HD+ CM10 sd card boot require rooting the HD+? Optimally, I would love it if it doesn't so that I, in my utter newbishness, could jump into android without voiding my warranty.
Thanks!

No it doesn't need rooting. It is independent from the system in internal flash.
You insert the card, it boots CM10, you remove it, you have old untouched original system

Thank you! That's what I thought, but wanted to verify that what held true for the nook color/tablet was still true for the HD+ (and hopefully HD in the future).

Please post links for instructions, root files, CM 10

Just look in dev forum for CM10. There are not that many threads there. And for root look at someone0's all-in-one thread in general.

[Q] Full Android HD+ As Yet???

As an original Nook Color owner from its first day availability, I am now ready to make the leap to the HD+. My primary reason for this is the 8.9 inch screen which emulates "trade paperback" size which has always been my reading goal along with enhanced video.
I have put my NC through numerous iterations over the last two years plus and finally did a full conversion to Android 4.1 a few months ago bidding a permanent farewell to any remaining vestige of the BN software. As the final remaining issue for me was "reading in store" which I no longer need, it was not a difficult decision.
In perusing this forum, I appear to have run afoul of trying to determine if there is a currently viable track for complete conversion of the HD+ eMMc as I simply do not need or want the BN interface. I know full well there are rooted, sdcard, and "hybrid" variations well explained in this forum but simply cannot find or continue to overlook any mention/instruction for full internal conversion as an option.
Am I simply overlooking that info or are we not yet there? If that goal has not yet been obtained, what would be my closest non sdcard option?
I have nothing but accolades and praise for those providing us with the fruits of their efforts. My multiple and varied experiences with my NC provided a truly fascinating experinece and learning curve starting with basic rooting up through several dual boot variations and now in eMMc Jelly Bean and all of its remarkably functional glory! It is clearly continuing with the HD and the "+" and I wish to express my deepest thanks for those continuing efforts in advance.
Any reasoned advice, suggestions, and/or direction would be appreciated.

As yet there is no full replacement of the emmc. The boot loader lock that even checks system makes it very hard.

Verygreenhas said he believes it is possible but not on his priority list, see his CM10 thread. We don't have many developers working it yet. And being CM working properly, kernels, etc are priorities now.

I too came from the Nook Color and have enjoyed the versatility of that device. Unfortunately B&N has locked down this device to make it more difficult to modify it. Your only two choices now is to modify stock with my CWM zips or opt for running CM10/CM10.1 from SD. You can get my CWM zips from my HD/HD+ CWM thread linked in my signature.

Get the HD+ and put cm10 via sdcard on it. If you use the right sdcsard (class 4? someone will correct me if I'm wrong) and dont look back. I came from the nook color 10.1 emmc myself. I know how soul crushing it was on there. Lag, reboots, lag, poor display, lag. Did I mention lag? I'd like an emmc too, but seriously you won't notice any difference. Its an amazing tablet with cm10 on it.

I have also had the Nook Color and the Nook Tablet.. the Nook HD/HD+ are awesome. I have always choose to ditch the stock B&N expereince. Currently booting CM10.1 from mircoSD on my NookHD, thanks to some awesome work by others, and its honestly great! maybe a few tiny little lags every now and then, but nothing close to a deal breaker. And its still early... so it can only get better from here. Going HD or HD+, you won't be dissapointed.

Actually this is strange that we dont have still bootloader lock hack. All tech things that i seen on xda forum are ulocked. And now some BN can lock it
I want help but i dont have knowledge for this stage. And with other words i need it too (run custom rom from emmc)..

Verygreen says he thinks it can eventually be done, but his priority is perfecting CM on SD. He says no real need to run it internally when running on SD works so well.

Thanks to all for your comments, updates, and suggestions. I opted to take the "easy way out" this time around and d/l n2a's $19.99 version for the HD+ and installed it on a 32 GB card. Oddly enough, could not get it to run on a new Sandisk Class 10 but it ran on an older class 4 or 6 card that I had used for converted film storage with my NC. Any idea why that happened?
BTW, when formatting a card for the HD+ should we use FAT32 or NTSC?
It is great to have a full JB interface back!
Not at all enamored of the current BN interface which I hope now to leave alone and eventually replace when full eMMc access is achieved. If JB could be made "ready for prime time" on the NC, then I am sure that it is just a matter of time until one of you has a full blown "Eureka" moment and shows the way to a full and total conversion of the HD+.
Will keep you all up-to-date regarding my experiences with the N2A setup.

Actually i need run it internally because i have 12 Nook HD+ and clients who use these just may pull out SD (maybe steal SD too). All restrictions which one i made on ROm for user side is not working anymore.
Seems i need directly constact with Verygreen.
Thanks about sharing information.

Not sure what the above direction has to do with which format (FAT32/NTSC) is best for SDcard use in the HD+ for either simple storage or alternate OS.
Did I miss something or was I unclear?

This quote at this thread is about SD card formating:
For first time install only (you will need 4G or bigger sdcard, smaller ones are not supported and not tested):
gunzip cwm image and write it to your sdcard (entire sdcard not just one partition of it), use either dd on Linux/MacOS or Win32 Image Writer for those impaired by Windows.

And when you follow this guide step by step, you dont need worry about formating your SD to wrong format.

Not all cards are created equal. The recommended card for running a ROM is SanDisk class 4. Others may or may not work well.
And it does not matter what format you had on the card originally before you burned the image to the card. It gets overwritten.
But for using an SD with stock, the card should be formatted Fat32 or ExFat. NTSC does not work.

[Q] Nook HD, CM 10.1 w/ CWM earlyaccessv4 - How to diagnose mysterious reboot(s)

Hi All,
I have a Nook HD, recently purchased and then updated to BN 2.0.6 firmware during the BN registration process. I used the sdcard-cwm-early5.img.gz as referenced in Verygreen's post here to create a bootable CWM SD. I then installed the CM 10.1 build posted in thread by Bokbokban here. Finally, I installed latest gapps from goo.im. All seems to be pretty good, excepting that sometimes, seemingly randomly, the device will reboot itself, at which time it bypasses the SD during boot and goes straight for the stock BN rom on the emmc.
Any ideas on how to proceed? I haven't seen a pattern in the reboots yet, so I am not sure what may or may not be causing them. While I'm not exactly a newb with all that is involved with rooting/flashing various android devices (I own 5 of them), I could use some guidance on how to troubleshoot or diagnose problems like this.

I am confused. You used an HD+ image from verygreen and an HD ROM from bokbokan. How did you make that work? They should not have worked.
But if you really only used HD files, the reboot problem is probably the brand and class of the SD you used. It needs to be SanDisk class 4. We have that problem a lot on the HD+. It is cause by a kernel panic when trying to write to SD.
The solution is to get a better SD or use bokbokan's new Hybrid SD setup that puts /data on internal memory so SD speed does not matter.

Thanks for your prompt reply. To be clearer, I did not use the HD+ image, but I did use the CWM image Verygreen posted, 'sdcard-cwm-early5.img.gz', as that version supported using CWM to read .zip's from /emmc (in other words, those that were downloaded via BN stock browser).
At the risk of sounding like I am second-guessing you, I think it's worth noting that I had no trouble with many things related to writing to the SD card: writing the CWM image, booting into CWM from the SD, writing the CM10.1 image onto the card, booting from the 10.1 rom, etc... So if it is, as you say, the card having write issues and causing a kernel panic, I'm wondering how I can prove that. I will check the kernel logs when I get home.
I'm using a Sandisk 'ultra' class 10 16gb... I get that 'class 10' generally means 'crappy for small random write requests', but I've had good luck with this particular card on other platforms that are sensitive to consistency of write speeds (G2, Nook Color). However, I'll try a class-4 Sandisk per your suggestion.
Follow-up question: I can't seem to find a solid guide that shows how to install to emmc... is that a new frontier for this device? Is it just that nobody has bothered, or is there a problem with original bootloader supporting that?

The internal bootloader is locked down pretty good. Some day someone will be able to break it, but for now no one has.

[Q] **HELP** New Nook HD questions...

I've just recently purchased the Nook HD and I did not know I was going to dislike the B&N system it runs on. I just want to run the Android system off of it and it is very difficult. I researched plenty of ways to do it, but they are all very complicated. I have an SD card. Is there an easier way to put the Android system onto my Nook?

No, if you want something besides stock you must use an SD.
I have a simple description on how to install the hybrid on the HD+ linked in my signature. I know you have an HD, so you need to follow my guide but use the files from the HD Hybrid thread. Also on the HD, the converter zip is not necessary. Just skip that step.

[Q] Confused with SD Install of CM10 on Nook HD

:crying: My brain hurts.
I'm trying to figure out how to install CM10 onto an SD card so I can dual boot my nook HD, but each time I read the instructions I get lost in more and more threads to the extent I'm totally and utterly confused.
In the thread http://forum.xda-developers.com/showthread.php?t=2063968 is
CM10 sdcard Installer (For CM10.1 installation additional step in the instructions should be followed)
Due to many problems/issues encountered by users with regards to adb and sdcard not working in Windows, I have combined the two files below and written a short script to automate the installation process. Just insert the sdcard to your device and it will be installed with CM10 automatically. No user intervention is needed.
Instructions
Download the compressed image file cm10-sdcard-installer.img. Posted: 12/28
Unpack and write the image to your sdcard. For more info on how to do it, see this post.
(optional) To install CM10.1 instead of CM10, replace 'CM-10-hummingbird.zip' of the SD card boot folder with any CM10.1 image file you can download here in this page (you need to rename the file exactly as above).
Insert into the device and boot (cold)/reboot (warm).
Wait for it to finish installation.
Enjoy your HD with CM10 (CM10.1)

which is simple, but does this "install" to the SD Card, or to the nook's internal? All the instructions I've read for making a dual boot say you need to install CM onto the SD card, which I understand, but how do I *know* I'm about to install to the SD card rather than overwrite the Nook?
Helllpppp!!

Two things tell you. First the CWM itself will say for SD and second, the name of the zip file says for SD.

Just bout a Nook HD from the pawn shop. Turn it on and it wants me to register. I have 2 Nook Colors. I registered them. rooted and added Cyanogenmod. Seems as I recall back that it was best to register them right away. I was just thinking, why? Why not just update it with no registration. Pros and cons please. Thank

The only advantage to registering a new nook is it starts your warranty. But since this is used from a pawn shop, it is probably registered to someone else and you can't register it anyway.
