B&N on SD? CM7.0.2?

I apologize in advance because I know this has been answered before (heck, I've even seen the topic, but wasn't interested until now) but there are so many threads and searching didn't lead to anything conclusive, so I thought I'd just make a new thread...
Is it possible to boot the B&N OS from an SD card? If so, is it possible to get 1.2 on there or only the 1.1 right now? I just picked up an SD card and was thinking what am I going to do with my old one, and thought I really want to check out 1.2 or even have a copy of 1.1 that's bootable while still having CM7 on my internal. Preferably, it would be unrooted, but rooted would be fine too, if it was needed.
My second question is what is the difference between CM7.0.0 to 7.0.2? I don't need specifics exactly as I know I can get that from their website, but more is it worth updating right away or waiting for 7.0.3 or above?
Thanks

I have not seen anyone try to install the stock rom on the SD. I like the idea.

I know it's possible the other way around and not sure why it wouldn't be possible this way. I think I'll have to look around more if no one knows the answer.

Yes, it is possible to boot from an SD card

I had this working on both Stock 1.1 and 1.2 (after the upgrade). Got stuck with the upgrade because I had CWR installed, but once that got taken off, the update went fine. Put the card back in, and CM7 was back!
Don't use just any micro SDHC card...I highly suggest Sandisk 8 gig class 4. You can get class 6, but anything higher than that has been reported to have issues.
To boot the stock rom, you'll need a copy...I believe that's floating around. Just check the threads.
Both 7.0.0 and 7.0.2 are "stable" releases, and I suggest unless you want to live on the edge, you use only stable. Both worked for me; you can check out the changelogs, but the major difference is simply more bug fixes as well as more capabilities (hopefully).

he meant have the stock firmware on a sd card, and keep cm7 on eMMC. i am very interested in this as well

I canhas method to run b&n from sd card pwease?

Nope, no luck on the above method (the CM7 method). I'm sure someone with knowledge of how it's done can do it, but that's not me...I'll keep looking, though, and update if I find anything.

A Couple of Questions Please if I May :D

First of all, really big KUDOS MUCHACHOS to the CM7 Dev guys! I had already donated a pretty hefty amount due to using CM7 so much on my Evo but I donated again cuz this is awesome! I do have a couple of questions tho, which I can't fine answers to. I did search for them but really had no luck. The NC community is not yet as organized as the EVO one, I am getting conflicting information and in general having a really ***** of a time finding anything so sorry if some of this has been answered(Im sure that's likely the case at least for some of them).
I used the size-agnostic SD card thing to make the SD Card i had into a CM7 install. Running the latest stable(as of 2 days ago). But thing of moving it all to internal memory. So here are my questions.
1: If I do this, will I be able to still access the real NC OS that shipped with the device? The Nook for Android app sucks, it won't play several of the books I already got(says they are invalid format when I try to DL them) so it is imperative to me that I keep access to the NC OS i have now(but I wouldn't care if it were on the SD card as long as it worked for reading books).
2: What will CM7 be like if I do this? I am gonna assume it won't take so long to boot anymore? Will it basically be a giant phone? Full access to the SD card? Still able to use the internal memory as storage(I use it to store music now)? Work exactly like my Evo does now? Except that it won't make calls of course.
3: Rooting. It seems that so many people are running CM7 that the guides/walkthroughs on rooting are hard to find. So a simple question or two pls Which method should I use? What, if any, are the drawbacks? I would still run CM7 most of the time but while in NC OS to read or something it would be nice to have access to android market etc as long as it wont effect my install of CM7.
4: CM7 nightlies. Can I run them from the SD card as well? If so can I just flash them right over my current SD card install without losing everything?
5: Can i run the OC Kernal while running CM7 from the SD card or do I have to run on Internal Memory for that to be possible?
Thanks for taking the time to read this pls answer any questions that you can I'd appreciate it so much!

I'll answer what I can.
1: Nope, stock ROM is replaced when you install CM7 to emmc. No way around it.
2: I'll have to defer on this one, I've always run from SD card. BTW, you are running from a class 2 card, right? The "faster" cards have serious issues.
3: My understanding is that you have to use ManualNooter for B&N 1.2. I haven't gotten around to rooting it since I upgraded to 1.2, but it was painless on the earlier ROM. There were no drawbacks, besides the fact that it's not CM7. ;-)
4: Yup, they just flash right over just as long as your following verygreen's instructions.
5: Yup, OC from SD works fine.

I don't know the specs on my SD card, it's whatever came with my EVO. I upgraded to a 32gb on the EVO so I used the old one for the Nook. My Evo is only a couple months old if that helps ya.

[Q]How can I make my ROM self booting?

I've been a happy owner of a rooted Nook Color now for several weeks. I've played around with it and got it running the way I want and it is stable and speedy. If I wanted to pack up my current rom, clean off personal data and slap it onto a self-booting SD card, how would I do this? I've gotten a friend interested in this now and would like to generate a rom that would boot up that nook with the configuration I've setup.
Any information or pointers in the right direction would be great. I've done some research and seen existing roms that can be used for self booting but I'm hoping to find a way to put my own together.

But what you ask is the standard.
If you have ready card with rom and its inserted, it will start booting from there

Yes I personally have a nook that boots up from a card. What I would like to do is clone what I have and put it on another card so that somebody else can boot up a nook color from it.

I think I get what you're shooting for. You essentially want a base image you can load onto other NCs that contains everything on your current system, minus personal info.
I don't know if you could just remove the account associated to the NC, create a backup, then load it onto another card for restoring.
Additionally, if you are using the stock OS, but rooted, I think your B&N registration information will still be attached. I don't know if you can clear this from the ROM, or if there is any device specific information associated in the ROM elsewhere.
Pretty much you want a deployable image of what you have currently, similar to deployable images companies use on PC systems.

Yes that's basically it. I'd like clone what I have, boot it up, strip out any personal data like contacts, my netflix login, etc and give the card out so that the nook can be booted up. I'll try the method of backing up the rom, moving the back up to the new SD card and doing a restore.
The OS isn't a stock one. It was previously phiremod that I changed over to CM7 build 150.

[Q] NOOK COLOR Rooting......

I have a brand new Nook Color the Software Version (in about my Nook) says 1.2.0. what is the easyest way to go about rooting? is there a specific version of CM7 that I should use? What is the best rooting method or system to use? I am totally new to all this so some step by step instructions or detailed informatio would be great!!! Thanks for all you guys help!!!

There are several decisions you need to make before you start. Do you want to have dual boot (meaning that you can switch between stock rom and another rom of your choosing? In these case you would be running the non stock rom from the sd card. Or, do you want to go full non stock rom (emmc)? There are different methods for each.
After you decide this, you need to decide which custom rom you would like. The most used are CM7, phiremod and MIUI. CM7 is the most update one and has a lot of following and development.
If like you mention on your post you are looking at using cm7, then I suggest you start with the latest stable version 7.1 (which was released a couple of days ago). You can find the files and instructions in this post and the detail instructions here
Hopefully this can help you, you could also look around in the android development section in the forums for further info and/or wait for more detailed info from more experienced rooter than me

Thanks for the Advise/ information, so if I go dual is it very complicated to switch from one to the other? is there an advantage to being able to switch back and forth? I currently have a 2gb sd card that should be big enough right? Once again thnks for the help..........
Does anyone else have input or feedback???

Just last week I installed CM7 on an SD card in my Nook Color. It's been great so far. I figure I'll try it on the SD card for a while before I do anything more permanent like installing to the internal memory.
When you install to the SD card, you boot back into the "stock" OS by just removing the card.
As for the size of your SD card, I think 2GB is large enough, but that depends on how many apps, etc. you plan to have on it.

I would not recommend doing that. The Nook card slot is a little fragile and excessive swapping will likely damage it. Mine gave out and I rarely remove the card as I have CM7 on the eMMC and only use the card for backups and upgrades. I had a hell of a time restoring the stock ROM so I could return it under warranty. If you are going to run from the card, set it up for dual boot so that you just pick which ROM you want to use when you boot up.

[Q] Nook Color Rooting Issue.

New here, yes I did look around. Found lots of other good info, but not this. If I missed it, feel free to remove my man card. I just got a nook color for x-mas yay me. I have followed two guides:
Well I tried to post two links but that wont work. I understand. Anyway, one guide is called How to Install CyanogenMod 7 on the Nook Color (PC Version), found it on Youtube. Other is called How to: Root a Nook Color, install CyanogenMod 7, and overclock it off of icrontic.com Hope that helps.
I am using at 8gb version to write to SD card. I copy both files over without un-ziping them. Follow all directions. However nook will not boot into Cyanogen. I just get the normal nook boot up. I have tried several times. I am new to the whole rooting thing and have seen people post different versions of the same file. Not sure if that has anything to do with it.
Lastly,
Nook firmware: 1.3
Not using a Scan Disk SD card.

I assume you want to enjoy the beauty of CM7.
Before guiding you, a very first basic question needs to be asked: do you want/intend to run CM7 on eMMC or off the uSD?

I assume you want to enjoy the beauty of CM7.
Before guiding you, a very first basic question needs to be asked: do you want/intend to run CM7 on eMMC or off the uSD?
Well I didn't know there were other options other than CM7. I have also been told that is one is the best all around one out there. You will have to excuse my ignorance but what is eMMC and uSD?

Don't worry, we all learn something day to day.
CM7 is a custom ROM (or OS if you want to call it), which replaced the stock OS by many of us. It is one of the most used ROM out there for NC (short cut for NOOKcolor)
In order to run/use CM7 on the NC, there are 2 choices:
1. Installing and running it (CM7) from the internal memory (a.k.a. eMMC) or
2. Booting and running it (CM7) from the external uSD card
You can spend the whole day searching for the difference in details, here, I just give you some quick thinking of the 2.
Running from eMMC = more complicate installation process, smooth performance, a lot less FC's (Force Close = applications hung), easy to backup, more storage. But you will void the B&N warranty since you delete their original stock OS.
Booting off uSD is a quick way to explore the beauty of CM7 or any custom ROM WITHOUT effecting the stock OS, meaning still under warranty. Down side is you need to have a 8GB or 16GB Sandisk class 4, which probably costs about $20 (onsale for 16GB).

Ok does it have to be a Scandisk sd card? I thought loading CM7 via SD card removed the warranty also. A side question I have. I saw on youtube someone was able to "dual boot" the nook OS with the CM7 OS. They could swap back and forth, any idea what this is about? Sorry I don't have much more information on it than that.
If loading through SD card does not void warranty I would prefer that for the time being until I get the hang of this stuff more. Then again a fully rooted nook is basically a android tablet+nook. The only reason I would want the warranty is if something inside were to break.
Would the reason why my attempt didn't work be related to the fact that I didn't have a Scandisk SD card?

No, it does not have to be a Sandisk but Sandisk (class 4) is the best (have been tested) on the market. You can use any other brands, it might work and might not. Therefore, if you intend to run CM7 off uSD, Sandisk is strongly RECOMMENDED. If you use the uSD as an additional storage, any brand is OK.

No, it does not. Running off uSD has zero effect on stock OS.

A lot of people mistype or mis-use the term "dual-boot"
AFAIK, there is 2 kinds of "dual-boot" (one of them is incorrectedly used)
a. Leaving stock OS on eMMC and booting CM7 off uSD.
b. Installing 2 different ROMs on eMMC.
I personally choose to say b. should be called "dual-boot", not a. but a lot of people calling a. as "dual-boot". I don't mind.
What your question is for item a.
All you have to do is during powering up, press and hold the "N" button then select booting Normal, it will boot into whatever on the eMMC (i.e. stock OS) even having CM7 uSD plugged in.
If loading through SD card does not void warranty I would prefer that for the time being until I get the hang of this stuff more. Then again a fully rooted nook is basically a android tablet+nook. The only reason I would want the warranty is if something inside were to break.

A very good choice. Go for it.
Note: recommend getting the Sandisk class 4.

I don't know what you're doing so can't say.
What have you done?

Ok sorry it took me a little bit to get back to you guys. I work the night shift so it can be a pain and make you seem like a ghost.
So I downloaded a file called 8gb_clockwork-0.7. Used a program called Win32 Diskmanager to write that file to the SD card. I have an 8gb SD card. Not Scandisk.
I then copied over two file that are .zip files. I did not un-zip them. Files are gapps-gb-20110307-signed and update-cm-7.0.3-encore-signed.
I am using my phone as a micro SD card reader. Could that be causing issues?
Everything I read said to do what I just said/did. I then pop in the SD card into the nook. My nook then boots up normally, I.E. standard nook OS.
Any help would be greatly appreciated, thank you.

Again, it goes back to my question in post #2.
Before getting an answer from you, I cannot provide any more help.
In fact, I don't want to guide you through the wrong direction.

I would like to run it off of the USB drive until I get familiar with it. Just in case I do not like it. As this is my first time rooting something I would like to keep my options open.

I assume you meant to run CM7 off uSD (you said USB drive???)
Anyway, if that's the case, what you have done was incorrect.
Forget about it, start over again.
With your not Sandisk uSD card, I wouldn't recommend but if you have to use it, then go with it for now.
1. download "win32diskimager" (I hope you already it)
2. download the "Size-agnostic SD" v1.3 imager from this link: http://forum.xda-developers.com/showthread.php?t=1000957
3. try this ROM (build 12122011) as many others like it from this link: http://forum.xda-developers.com/showthread.php?t=1344873
4. download this GApp (20110828) for CM7 from this link: http://wiki.cyanogenmod.com/index.php?title=Latest_Version
5. try to follow verygreen's instructions from the link that I posted in step 2.
If you not able to or hitting issue, get back here for more help

Will do. Thanks again for all the help. Also yes I did mean uSD :/ I will try this Wednesday during the day and get back to you as I am about to start another shift.
