Nookie Froyo EMMC vs SD... which is better?

I have a brand new Nook, freshly Rooted. As Im getting into the meat of hacking this thing I see that Froyo can be installed via SD or on the EMMC. Which would be the better direction and why?
I should note that if installed on SD I would be installing it on a 32gb Class 10 MicroSD.

If you put it on the EMMC then you will loose all B&N functionality that the NookColor came with. No NookKids and no magazines. You can use the Nook android app in Froyo but I personally like the NookColor's applications. Once we can port these apps to the Froyo build I would switch. Froyo seems to run better with Jit and other optimizations

So does this mean that if it is installed via sd that the NC wont lose the B&N stuff it came with? Or are you saying it's all gone either way and to wait if we don't to lose the things?

It doesn't "install" via SD, it's booting from there(bypassing the internal memory entirely). That way you can just pop out the SD card and voila, the nook boots whatever is on the internal memory.
The SD method is good because you don't risk leaving some trace on the device if you have to return it under the warranty (or for being able to access B&N apps and boot froyo).

As it sits right now, Nookie Froyo on the internal memory(emmc) is a bit of a pain to do. Heed the giant red FOR DEVELOPERS ONLY warnings. If you want to get a taste of what it will be like, just install it to a SD card.
Work is progressing on an "update.zip" which will completely flash the internal memory with NF, in a sane and safe manner(no bricks!), via Clockworkmod Recovery. This is the same way that all Android devices get flashed.
The B&N apps are not available in NF, and I would not expect them to be - they seem to rely on quite a few incompatible framework changes, in much the same way that Sense UI's widgets can't be used on a Cyanogenmod phone. If it means THAT much to you, just stay with stock.

Thanks for the replies. Looks like SD is the way to go... for now.

[Q] root/rom question

now I realize I'll prolly get the lynch mob soon after i post this... being that all the research is over in the dev section, but my question is fairly complicated and i cant seem to find a direct answer from my own reading.
now i have root on my NC and i would love to put a custom recovery/rom on my NC. could any one point me in the right direction to get me started loading a custom recovery? i dont want to run froyo off of an SD card i would love to have it just be a giant version of my phone(I'm sorry if that's asking to much)
i learned and pushed myself to do it a while back on my EVO 4g when i saw there was a rom with wimax capability's and that was my first time rooting anything. I do on the other hand work as a sprint instore service and repair tech. so all of this reading isnt completely lost on me.
and my second question. when i booted my nook back up after i let the battery die, all my setting and apps were gone. any one know anything about it?
thank you for any answer, and I'm very sorry about my spelling and grammar, i know it sucks >.<

i think my biggest confusion/hangup so far has been the custom recovery not sure if i have this right or not but. these are the steps (i think) i need to take.
1. aquire root. [check]
2.custom recovery.[?]
3.custom kernel.[?]
4. custom rom.[?]

So what you want to do is flash a custom rom? You would just download a CWM sd card image. Burn that image to your SD card. Then, grab the rom you want, such as nookie-froyo, or whatever. Copy that zip to the SD card.
Put the SD card into your nook, then reboot. It should boot into CWR and from there you can just flash the zip. The same thing with a custom kernel, just copy the zip onto your CWM sd card, reboot, and flash the zip.
I'm not sure if that is what you are asking, though.

I've actually figured it all out finally. is there any way to see what my CPU is running at?

The speed of your NC can be done by downloading 2 free apps in the market:
Linpack for Android
Quadrant Standard
The Linpack app will tell you how many MFLOPS (Millions of Floating Point Operations Per Second) and Quadrant will give you a score to benchmark for CPU, I/O, and graphics. They will also give you as a reference how you compare to other devices.

So I'm new to Nook. In fact it's still being shipped for the wife, lol. Little that she knows, it's getting nootered before it even gets in her hands.
I've rooted phones and flashed custom ROMs.
From what you're saying above, does CWM reside solely on the SD card? That's different than a mobile phone. So any time we need to install a custom ROM (even the first time), we'd have to boot using the SD Card that has CWM, right? Of course I'd have to root the nook first.
following should really go into a different thread:
So whats the best ROM? So many out there. I just want to be able to use all google apps and market (for kindle app).
Thanks in advance.

You can still install Clockwork from the market and it'll run of the NC without an SD card. I've done it. But for the installation of CM7 (something to do with EXT4? I don't even know what that means...) CWM on an SD was necessary.
On what the best ROM is. Well, looking in the general section subsection here it looks like a lot of people are on rooted stock 1.1. I tried Froyo and it was cool and all, but I missed having the full 8GB of storage on the nook. I haven't tried Honeycomb yet, so no idea on that one. I currently have CM7 nightly 8 on my NC and really like it. I may not have all the storage space still (they're working on it) but it's snappy and sleek.

[Q] Newbie Nook Color owner needs guidance :-)

Hi all,
After reading all the great stuff about the NC recently, CM7, Phiremod and the honeycomb releases Ive convinced a mate of mine in California who's visting the UK to bring me one over to tinker with..
Now.. After doing some research Im overwhelmed with info and thought Id ask for "up to date" pointers..
1. Is there a straightforward guide to rooting and installing the NC, as I live in the UK Im not fussed about the original NC rom. I've seen Cyanogenmods wiki entry http://wiki.cyanogenmod.com/wiki/Barnes_&_Noble_Nook_Color:_Full_Update_Guide is this the best approach?
2. Which rom is best? Plain CM7, Phiremod or Honeycomb as posted by deeper blue?
3. Any other pointers?
Sorry for such basic questions, im just overloaded and not 100% sure which is the best process to take.
thanks all in advance
Angelo

Take a look in the stickies, there are comprehensive guides to root....just make sure you're using the correct version. If your mate is buying a brand new one for you, you'll most likely need the version for rooting with partitions. I have used all 3 of the roms you mentioned and my personal preference is CM. Phiremod is just a heavily themed version of CM and the honeycomb build is ok, but it lacks some features and is still a bit buggy because the source code has not been released for honeycomb

If you decide on CM7 (which I personally recommend), I would look for "How to Install CynaogenMod 7 on the Nook Color" (can't post links) on YouTube. I personally found it very useful. If something seems off, make sure you look at the description and read some user comments. With the way this guy explains it it's practically idiot proof and it's unlikely you'll mess anything up.

thanks
Thanks Guys,
I've been doing more reading and yeah looks straightforward..
Considering Im not interested in the core B&N OS, I was thinking of installing CM7 to the internal memory and then perhaps installing Honeycomb (deeperblue version) on a memory stick to "play with".
From what I can tell the HC port is nice as a toy but not robust enough considering HC hasnt been released to AOSP.
Makes sense?

If you are looking to 'play with' honeycomb on a MicroSD install, check out http://forum.xda-developers.com/showthread.php?t=1045018
You get Honeycomb and Phiremod in a dual-boot image tailored for a MicroSD install.
Read through the thread and see if it's to your taste.

For the most usable ROM, go with CM7. Just follow this guide in this post. Very simple.
http://forum.xda-developers.com/showthread.php?t=1030227
The only issue is if you have a "blue dot" with the newer partition. Just read the RED text at the beginning of that post.
After you get this running, you can read up a little more and create a SD card w/ Honeycomb or Phiremod to play around with. But CM7 is the most stable out there (well, I guess Phiremod is good to, because it is a customized CM7).
Good Luck.

Use CM7, it's the best for now.
HC is beauty but still a lot of work to be done.

+1 for this guide!

"The only issue is if you have a "blue dot" with the newer partition. Just read the RED text at the beginning of that post."
For some reason I thought that statement was obsoleted, am I wrong?
It was valid if you have v1.2 NC and flashing with CwM Recovery prior to v3.2.xx.
But since the instructions do indicate using v3.2.0.1 CwM, then why care about blue-dot or not since it has been taken care off unless v3.2.x.x not properly does the job.

Maybe because you have a choice in partition schemes?

You really will want to repartition the new nook. 1 gb is a very small partition for your programs. 5gb works much better and the change is fairly painless.

That's a reasonable reason but again, it shouldn't be highlighted in RED, ORANGE at best
In fact, since it's a choice of good, it should be in GREEN.

thanks guys
Thanks guys, Im in awe with all the feedback and comments this thread is getting..
yes, Ive received the NC today and its charging Also doing loads and loads of reading
My nook does have a bluedot so my partitions are 5gb Data/1Gb Media.
I'll probably leave it like so, considering CWM supports this now its ok, and put most of my media on an external 16gb microsd card..
If Im right I can still install apps into the 5gb partition right?
Also , if I understand it correctly I can actually install CM7 onto a microSD and simply boot from this right ,without rooting/installing CWM... ?

You can still install apps into the /data partition but pls note: if your NC isn't rooted, you can only install apps that offered by B&N. You do not have full access of Android Market.
About CM7, yes, you can run CM7 off uSD and not touching the eMMC (aka internal memory) at all. Be considered getting a Sandisk (class 2 or class 4)

B-i-g thanks
All,
BIG Thanks to everyone,
I've successfully (actually flawlessly), repartitioned my nook to the old standard and installed CM7 into the internal memory..
All flawlessly. Also ordered a sandisk 16gb memory card from amazon.co.uk, so that will hold most of the media..
I was considering making the main partition >1Gb (1.9Gb) but decided to leave it as it is for now.. It was so easy yo tweak I thought Id try it vanilla and then grow if I need to..
Awesome-ness

ok wheres my 5gb?
ok got one question now..
/media is supposed to have 5gb available..
CM7 doesnt appear to allow me to use it as a SD card.. but ive found it mounted as /mnt/emmc
How does one use it ??? I tried downloading pdfs and I was told that an SD card was required for this... :-( when i get home I was going to try mounting it via usb to a computer but is that the only way?

There are 2 things you need to know
1. If you're running CM7, you MUST have a uSD. "MUST" does seem to be a strong word but for some reason, that I still try to figure out, an external uSD is required. W/o it, you can still using it but there's some apps won't run if no uSD plugged. It means the NC works 99.9% w/o uSD. I guess I should take the "MUST" back, ehhh
2. If you're running the recently nightly-build CM7, the USB storage utitlity should already be implemented within the ROM. All you need to do is
1. Connect NC and PC via USB cable
2. by this time, the usb indicator should be appeared on the NC, tab on it
3. Tab on Connect USB to transfer .......
4. Turn USB Mass Storage on
5. by this time, PC should recognize the /media on the NOOK
6. do what you want to do

Hey Angelo, I just wanted to share my experience.
I love gadgets, and tinkering with gadgets. I am an IT manager/minor programmer/webmaster, etc. etc... so no surprise that I feel right at home here BUT, I also love to read and I think that the Nook app for Android is bunk (e.g. "poor") compared to the stock NC experience.
I decided pretty early on that I wanted to keep the NC stock (partially due to warranty) and have a dual boot option for CM7. I had initially installed CM7 on my NC, replacing the stock rom all together. I ended up putting the stock ROM back on.
Here is a post from another thread where I outline that experience...and the guides that I use.
I talk about partitions in that post, since you have a new NC, don't even bother yourself with that...just note the guides there that will get you where you want to go, either way....

Many (older) apps in on Android are designed to ONLY look for storage called "sdcard". So your 5gb of internal (emmc) called "Media" will not be able to be utilized by those Apps.
Apps that are better programmed and designed can access the memory called "Media".

[Q] Putting rooted CM7 OS and Apps on bootable SD card?

Ok, first off let me say that I am a new member and love the site. There is a ton of great information on the site, but I seem to be having trouble finding an answer to my specific situation.
After hearing about honeycomb and gingerbread being installed on the NC, I decided to give it a shot. After reviewing each OS, I decided on going with gingerbread. I followed a youtube video and a few threads on XDA and eventually installed the gingerbread OS, Gapps, and Netflix.apk files on my Nook. Everything worked fairly well and I was happy.
My question to you all is, would there be a way to take all the apps, OS, etc. that I currently have on my Rooted NC and make an image of it to then put on a bootable SD card?
My ideal end result would be to have:
1. a Bootable SD card with my current apps, OS, etc. on it.
2. a freshly restored nook color.
3. the ability to either remove the SD card to switch between the GB/NC OS, or have a boot option when booting up the Nook.
Any help with this process would be greatly appreciated!
Thanks in advance,
Nick (Nudarkshadowl)

Help, several NOOB questions

THANK YOU IN ADVANCE FOR ANY HELP! I'm dead new with android and just got a Nook HD+ 32gb (groupon deal $130)
anyway, I've done a ton of reading on here and watched a bunch of youtube vids- i don't know if people use overlapping terminology that means the same things or what.. and also seems like theres a lot of opinions in the forums.
I want basically the full android experience and root access- like i said, never used any android, but i like toying around with these things. BUT i also really want a fully stable platform- don't want constant crashing or it reseting on me.
questions i have-
1)the CWM is the "program" (don't know the correct terminology) that basically gives me the access to back up and install new roms, root, etc? TWRP does the same thing- but i understand you don't use that?
2)If i have a BRAND NEW nook HD+ do i need to back it up before messing with it OR are the "stock rom" zips you provided just that?
2) with the SD card image, do i need to put a specific image on the specified sd card. i.e. 4gb SD gets a 4gb image? or is the image universal to whatever size SD card i get?
2a) What problems am i going to run into using my mac to make the SD card, if any? what program do i need to use?
4) when you back up through CWM where does it save it? to the SD card?
4a) this is where i was confused about the image, reading into some of the posts it led me to think the image file took up the entirety of the
SD card.
4b)So in the future i could just boot from the SD card and would have the option to flash the stock rom back on the HD+ if desired? and/or
go back to CM?
5) what is DUALBOOTING? and NANDROID? how do they tie into CWM and CM10. very confused about this.
6) any disadvantage to flashing the EMMC vs booting from SD card every time? I THINK i want to flash the emmc, i don't want to be tied to booting from the SD card everytime- if I'm understanding that correctly.
7)what is this "trim" lag problem? couldn't really figure out what people were talking about.
thanks a ton for any help you can give me- I'm sure you receive a lot of questions!

CWM (ClockworkMod) is a recovery program that allows you to do just what you said. TWRP is also a recovery, but uses the touch screen instead of hardware keys to control it.

You can either use the CWM backup tool to return your device to stock (including any data you have already created, like registration) or the plain stock zips I have will also return you to stock, but the way it was when you got it new before registering.
3) with the SD card image, do i need to put a specific image on the specified sd card. i.e. 4gb SD gets a 4gb image? or is the image universal to whatever size SD card i get?

Since you have a Mac, the best way to do it is the new procedure without burning an image. Since I don't have a Mac, I don't know the exact programs to use. I think SDFormatter comes in a Mac version. And I know there are lots of mac partitioning programs to set the first partition active. And using the procedure does use all of the SD, so it is best to use a relatively small one, 2-4GB.
4) when you back up through CWM where does it save it? to the SD card?

It saves it either to the SD card or internal memory, you choose.
Yes it uses all of the SD if you use the new procedure. But you need that if you choose to backup to SD. A backup takes about 1.5GB.
And yes, save the SD for future use, like restoring backups or installing new ROMs.
5) what is DUALBOOTING? and NANDROID? how do they tie into CWM and CM10. very confused about this.

Dual booting means having one operating system on internal memory (also called emmc for Embedded MultiMedia Card) and one installed to a bootable SD. Most people that dual boot have stock on internal and CM on SD. They are separate and independent from each other.
Nandroid just means internal memory. So a nandroid backup means backing up whatever you have on internal memory.

The only advantage to booting to CM on SD is it leaves internal memory untouched for warranty reasons. The disadvantage is it runs slower and is less stable.

LAG is a complex issue to explain. If you are used to hard drives getting fragmented and slowing down your system, LAG is similar but a different mechanism with solid state flash drives. TRIM is a process to undo what causes LAG. But some of the solid state chips in these devices have a bug and when TRIM is run, it bricks the chip, making it unusable.
