[Q] difference between root, cm7 and cm9 - Barnes & Noble Nook Tablet

i'm newbie
after rooting the nook tablet, i can install apps from apk files, and i also have google play store, i have new launcher, ....
i think that's good.
but what is cm7 or cm9 about?
i found that cm7 is "android 2.3", but the nook tablet running android 2.3 already.
so what's the difference?

Hi.
Rooting stock (the original firmware/ROM from Barnes & Noble) gives you only root permissions and perhaps some tools. Everything else stays and you need to do (uninstall/update/install) by yourself. Many things can be achieved, but not everything. It's simply still their customization of Android 2.3 gingerbread.
Cyanogenmod 7 is on the other hand completely clean installation of Android 2.3, without any Barnes & Noble changes, just with some Cyanogenmod team's improvements. This gives you all android possibilities, esp. compared to b&n's android, which was never meant to be a full tablet. To be more specific, with latest Cm7 on nook you get accelerated video playback, more configuration options, themes, chainfire 3D driver, stock android applications, etc.
Cyanogenmod 9 has the same idea behind, it's just on top of Android 4 Ice Cream Sandwich. It is not yet as mature as CM7 on nook yet.

What to do

I am running Vegan 5.1 with almost no issues. I want to upgrade to a newer OS but not sure which one I should try. Any suggestions??
My question to you is "Why?". If you're current install on your gTab is stable and it lets you run what you want to run why do you want to "upgrade" to another ROM. If a different ROM will give you something more than what you currently have like maybe let you run a cool video game (Shadowgun) which can't run VEGAn 5.1 then that would be understandable. I was a happy user of VEGAn 5.1.1 for a good part of a year and decided to move to Mountain Laurel 3.1.0 only for the fact that games like Shadowgun will run on it.
So, if that is the case and you feel you will get more out of your gTab by moving to a different ROM then I would suggest you do a full backup via ClockworkMod of your current install so if you choose to revert back to it after you've tried some other ROMs you will be able to do so easily.
Also, it is VERY important for you to figure out what version of the bootloader your gTab is currently running. You can save yourself a lot of wasted time if you figure that out first and then plan your path to a different ROM.
I have some apps that will not run on it. I am not sure if its the OS but I cant even download them from the market. I was hoping another OS would fix that. I also thought the newer versions of OS run faster? I am not sure but I am a newbie to all of this.

Since you like Vegan 5.1 then why not try VeganTAB 7.1, it is very stable.
I ran it using clemsyn's 1.6 kernal and it is fast.

Also the new CM7 7.2 which is also based on Gingerbread is another one I recommend.
I am currently using it. It comes with a 1.4ghz OC kernel already.
BTW to make thing runs better, change the VM stack size to 64M.

There could be a few reasons why an app will not run on your gTab or will not show up in the Market for you. It may be that you are trying to run apps that are for Gingerbread or Honeycomb. It may also be that your LCD density is keeping some of the apps from appearing in the Market.
As for newer OS versions running faster, I've tried about five different ROMs and VEGAn 5.1.1 is by far the fastest (you can overclock it if you want to run at 1.4 ghz or higher with custom kernels). So when I switched ROMs away from VEGAn 5.1.1 it wasn't about speed but rather better video driver support.
On more note, VEGAn Ginger and most other ROMs will take what seems like forever to boot up compared to VEGAn 5.1.1. Keep that in mind if do make the switch so you won't think your gTab is stuck during bootup when trying other ROMs.

How do ROMs work? (n00b question, I know)

Ok...I am really REALLY new to all of this. IF you put a custom Honeycomb ROM (CM7 is Honeycomb right?) onto a tablet, will it then run apps that are designed for Honeycomb tablets?

Cm7 is 2.3.7 gingerbread and apps working anyway.
Most.

The ROM is the same android OS but customized regardless of the android version (honeycomb, gingerbread, etc).
Different ROMs could have the same Android version. Major ROMs like CM are updated by their Developers when a new android OS is available.
Apps work mostly on any ROM, unless a certain app doesn't work on a certain Android OS version.
I hope I could answer your question.

Sort of....I guess I should break it down a little. There is a Words With Friends App that is made specifically for Honeycomb and because of that I can't even put it on my tablet which runs Froyo (parsing error). If I install a custom ROM or ported ROM like CM9, will it allow me to be able to install it?
CM9 is Ice Cream Sandwich I believe... It might run your app.
Go to the app page on the market and see if anyone is complaining about it not working with ICS... If not, you're good to go.
CM8 was supposed to be Honeycomb, but didn't happen because Google didn't release the source code for Honeycomb. If you find a Honeycomb ROM specific for your tablet, then that answers your question. Otherwise you might have to wait till an ICS ROM is developed for your tablet.

Any other way to get 2.3 on mini than CyanogenMod?

Yeah, title says it all. I have a XPERIA X10 Mini running android 2.1
BTW i want to go back to 1.6 just to try it out again, but i dont know how, is there any official way or do i need to mod etc ?!
Short answer: No.
Longer answer: Not yet.
Even longer answer:By the looks of things, all the Gingerbread roms available here have CyanogenMod inside them. Sony Ericsson haven't released 2.3 onto this phone and they're not likely to either, so the only way to get a 'pure' version of it would be to hope that somebody makes one...or make it yourself.
Why do you want GB without CM though? The reason so many people put it in their rom's is that it's very good. You get all sorts of improvements to the phone's functionality and performance.
As for going back to 1.6, there's no official way as SE will only give you the latest firmware. But you can use Flashtool to do it instead.
stock FTW!
I think the OP is like me and they actually prefer using the stock launcher. I've been looking for the same thing myself, a pure stock rom just updated 2.3.3.
I appreciate all of the cool tweaks and mods that CM adds to the rom but for me those tweaks usually end up borking another feature i'd rather use. I am also not a big fan of the customizations that some rom authors do like alternative launchers, heavily modified notification trays, weird fonts and color schemes. i'd prefer a just straight vanilla stock rom w/the sony launcher and camera; works nicely w/the screen realestate that we have w/the x10 mini. Again, i appreciate all the hardwork by all the rom authors/devs.
The big killer for me on the CM roms is the camera, still not up to the sony stock camera in my experience and again no stock launcher; some are close.
My solution was the following:
1. repair phone back to stock using PC Companion
2. reroot phone (bootloader already was unlocked)
3. reinstall CWM recovery
4. remove bloatware from stock rom (sony sync crap, game trials, quickoffice, etc)
5. update /etc/hosts file w/ad blocking version
6. create nand backup in CWM. (also made one after setting up miniCM7 in case i wanted to go back at anytime by restoring the nand)
if we could just get 2.3.3 in a pure stock form.. i'd be in heaven.. however, i may give the new ICS roms a try once they get to everyday-use-stable.
btw, the x10 minis have been the hardest to get root, recovery and kernels on of all of the android devices i've used yet. (Nexus one, HTC G2, LG G2x, Lenovo TPT, Galaxy Tab). mad props to the devs that got us to where we are now.

[Q] Purest Android experience?

I'm loving my newly-rooted Nook (Albert Wertz SD card method).
I'm not really into the Barnes and Nobel ecosystem, and have no need to maintain compatibility with it.
I know the NT is still fairly recent but, at the moment, what is the closest ROM to pure Android? ICS would be wonderful, of course, but I like Gingerbread and Honeycomb as well.
Thanks in advance!
CM7 (gingerbread) alpha is out, head on over to android development to find it. There is also a soft modded version of it and an MIUI (gingerbread based as well). CM9 will be ICS (android 4.0) but its still in development (no public release yet). There won't be any honeycomb rom as ICS is basically honeycomb without the **** and support for tablets/phones and a few added features.
tl;dr check out CM7
Thanks! I had good luck with CM7 on my G-Tab, so I figured that's where I'd end up.

[Q] Question about CM9

Do you have to load all the updates in a series or can you just load the lastest update on its own??
Install the latest. Make sure to wipe data/cache if coming from a different rom.
And for future updates (like chrmhoffmann's new .04 or eyeballer's new nightly) just wipe cache and dalvik. It is a good idea to to do a complete wipe and a fresh install every once in a while with experimental builds. It cuts down on errors.
Guys,
At currently stage, what are the pros and cons on using CM9 vs CM7.
CM9 is a proper tablet optimized experience as it is based on Android 4.0, Ice Cream Sandwich, the version of android that is built for tablets and phones. CM7 is based on Android 2.3, Gingerbread, the version of android that was designed for phones, so its appearance is that of a bloated phone.
Downside of CM9, is that hardware acceleration is not working yet, so netflix does not work, HD youtube does not work and most higher end games do not work properly. Downside of CM7 is that you don't get the "true" tablet experience and any Honeycomb/ICS only apps will not be available to you.
The nice part is that its quite easy to try each. Make a backup of whatever you're running, flash the rom, test it out and see if it works for you. If not, move on to the next rom or restore your backup.
That was the most complete answer i've received.
Thank You!
