[Q] CM7 Nook Kernel

I'm sorry if this is has been answered before but i'm a noob, but an actively learning noob =) There is so much information in these forums but it can be highly overwhelming with so much info out there and hundreds of pages, it's like finding a needle in a hay stack.
1. I'm unsure exactly what a kernel is.
2. I am currently running CWR 3.0.0.5 w/ (Nookie Froyo Custom 0.6.8). Can I / Should I update to CWR 3.0.1.0 even if I stick w/ Froyo? Will the update overwrite my system forcing me to reinstall everything?
3. I saw something about Tablet tools (or something similar in name). Does that get installed in CWR just like Google Apps? Do I install before or after the ROM (Froyo Custom / CM7)?
I would like to go to CM7. But am curious about different Kernels such as Darlingtons OC. Any other recommendations? I currently use SetCPU at 1.1 in Froyo w/ no problems.
Thank you for your help in advanced and to all the amazing devlopers out there!

First off, read more before attempting anything. I cannot stress enough that you should always be sure you understand exactly what you are doing, even if you're unsure how the process works, otherwise if something goes wrong and you weren't sure what exactly was happening you'll be kicking yourself later.
The kernel is the part of an operating system that actually makes the software and hardware talk to eachother in a sane manner, read: it makes everyone play nice hopefully. CM7 does include one in the image but if you read further on how to flash stuff you can replace the stock one with an overclockable version if you'd like.
Some of the documentation I've found can be a touch confusing if you're new to Android to be sure, I'd reccommend reading thinkgs a few more times and asking questions about specific tutorials, it will help get you started in the direction you'd like to go.

Kernel, in OS terms I answered above, in Android terms it's basically the same except how it is updated vs on say a Linux PC is different, isnted of just installing it normally you have to "Flash" a separate file, more on that in response to #4.

I have CWR 3.0.1.0 and it works great, I am not aware of it overwriting previously installed ROMs but I'm not a CWR dev so take that with a large grain of salt.

Link to the thread in question, I'm not sure what you're asking about on this one.

CM7 comes with its own kernel but Darlington's OC kernel works amazingly well, he has packages that you can flash via CMR just like you would GApps, just make sure you grab the one that is right for your install of CM7 (SD or EMMC depending).
Hope that helps

[Q] New Nook user with a few questions!!

Hi All,
Just joined the forums today after a few weeks browsing. I must say I am very impressed with the level of knowledge here and how helpful people are to others, especially noobs like me
Anyway, I got a nook color, but I am in Ireland, so I can't register it, that didn't worry me too much, because I wanted to root it, and after much reading on these forums I decided to use CM7.
My build at the moment is as follows, built with Clockwork,
CM7 RC4,
Dalingrins's OC kernel emmc 0413A,
Alsa 041411
First thanks to all the people who made the mods/ kernels etc Your work is really appreciated I am loving the nook color now with the mods.
I just have a few very basic questions, lol and I am still getting to grips with the right terminology
1. Does it matter which way I install mods/kernels etc? I understood that you had to install the CM7 mod first, but, for Dalingrin's OC kernel and Alsa, I installed the kernel first than Alsa, or does it matter?
2. If a new kernel comes out, or an update to Alsa, do I have to uninstall the old one? Or can I just boot into recovery mode wipe the caches and install the updates?
3. Same question for the CM7 mod, If I want to try some of the nightlies, can I just put the nightly on an SD card, wipe caches and install it the same way I did the RC4 version? will I have to reinstall the other kernels if I do this?
4. What happens my data and apps if I do update CM7?
5. I made a backup on the SD card using clockwork. Is this just a backup of the system files? or is it a backup of data and apps as well?
6. I am trying to learn more about this, in performance settings there is a thing called VM heapsize. Is there a recommended value for this?
7. And in the CPU settings there are a number of options available under "available governors" what are govenors? and which one is best? Is there an explaination available for each one?
That's all the questions I have for now. Very sorry if these have been answered a million times already!!

You should be able to upgrade with CWR. I have CM7 on a SD card and just add the new kernel and boot into recovery mode.
3. Same question for the CM7 mod, If I want to try some of the nightlies, can I just put the nightly on an SD card, wipe caches and install it the same way I did the RC4 version? will I have to reinstall the other kernels if I do this?

Since the nightly has its own kernel, you will need to reinstall the OC kernel.
4. What happens my data and apps if I do update CM7?

They shouldn't be affected.
I'll leave your other questions to someone else, since I haven't dealt with these issues.

thanks for tthe reply Bob.
Can anyone add anything for the last few questions?

Dalingrin Kernels for NC

I am very much new on Rooting the NC. I finally updated to the 1.3 and then used the manual nooter to root it again. However, after doing quite a bit of research, I have been seeing people posting about flashing the
" Dalingrin Kernels" ??
What are these?? and if it would help my NC to be a little more stable, or faster, could I use these?? and if so, how would I do this??
Thanks!!

They are customized kernels that allow for overclocking, and some other "unlocked" features. They are actually included in the CM7 nightlies now, so you don't have to flash them separately. You can go into the Cyanogenmod Settings to change the CPU clock in the Performance section to overclock. Other stuff that's working include bluetooth and usb host mode.
I would highly recommend just using one of the latest nightly CM7 releases. If you want to stick with rooted stock, then you should still be able to flash the kernel, I believe.

Add on to what pony said,
+ it created by Dalingrin, that's why it gets the name.
+ Dalingrin recently release new set of kernels in September, but I have no clue what news, enhancements or any advanced features added. I hope he will post the log some days.

Find the Dalingrin post in the Development section that contains the link to kernals. Use the 090111 kernal (there are two so pick the one that is to be flashed from the SD card). You can use the same CWM SD card that was used to install Manualnooter. Put the zip on the card, the card in the Nook, boot to CWM and flash. Following a reboot, you will be in business.
I did this when I installed Manualnooter 4.6.16 but you should be able to do it at any time. I coud not tell you if it makes any difference as I did not run rooted 1.3 without it.

Best option for NC 1.4.3 unrooted

I apologize in advance if this has been asked before, but I searched and couldn't find anything.
I never rooted my Nook Color (firmware 1.4.3) because I like the simplicity of it and I only really wanted to read books on it.
However now I wanted to install other readers so that I could read other formats without having to convert to epub or pdf.
I tried downgrading to 1.2.0 but it still doesn't let me install other apps.
What would be my best option?
Is there any way to do this without rooting?
I'm not afraid of tweaking, I just prefer the stock firmware to use as an ebook reader.
Best regards,
Rita

Best Option According to me
Rita,
Sincerely the best option for you right now is to run CyanogenMod 7 off an SD Card, a port of Android 2.3 for your device. I have a Nook Color too. I used to love stock but the lack of functionality made me install CM7. There are many easy to follow guides available on the internet. If you would like I can tell you how to install CM7 on an SD Card. That way you can enjoy both stock and CM7. Cheers!

You can do what the prior user recommended (CM7 on SD) and also go back to the latest stock software on internal memory and root it. Then you can decide which you want to use. If you look in my tips thread linked in my signature you will see how to flash the lastest unrooted stock software with CWM recovery. Look at my item A12. Then you can root it with Manual Nooter 5.08.20. You can add other apps with unrooted stock but only from the B&N app store. If you want more apps than that, you must root.

@satya-1998: I've already tried installing CM7 on a sd card and I liked it, just not for reading. As an ebook reader I really enjoy the simplicity of the stock firmware.
@leapinlar: I've already put the latest firmware on the nook (1.4.3) and I think rooting will be my best option. Will rooting and using manual nooter 5.8.20 keep the B&N functions and allow me to install other apps?
Do you think following this thread (http://forum.xda-developers.com/showthread.php?t=1494901) would be the way to go?
Thank you both for your help, Rita

And as far as I can tell everythig is working great.
Now I just have to learn how to work with the android part of it.
Thank you very much for the help, Rita

What did you do? Bootable uSD or root?

I followed the instructions in this thread (http://forum.xda-developers.com/showthread.php?p=22480277), so rooted and used manual nooter 5.8.20.

Ok, now that you have rooted your nook, you can keep it at stock and also keep CM7 on the SD card. If you like the B&N reading, download the Nook app for android onto cm7. Cheers...

do you have a link for loading cm7 on a sd card so you could boot between stock and cm7. my firmware is 1.4.3

Use this simplified guide.
http://taosaur.blogspot.com/2011/09/running-cyanogenmod-7-from-sd-nook.html

You can try a dual boot from
http://forum.xda-developers.com/showthread.php?t=959461&page=1
But I recommend going with booting off an SD card. Much easier, and although it can be a PITA swapping SD cards, you dont run the risk of losing partition space, or having a problem if you have to go to BN for whatever reason.

v1.3 to 4-6-16

I installed manualnooter-4-5-18 with no problem. But when I install manualnooter-4-6-16 device gets stuck on colorful Nook Color logo show.
My version is 1.3.
I also need some advice:
1. Isn't it better to use cm-7.2.0-encore instead of original OS? I can't decide.
2. Shouldn't I update to more recent versions of nook software (higher than 1.3) then mod it?
Thank you for software and support

It depends on what you want.
If you are invested in the nook store with lots of purchased apps or want to read interactive kids books, stay with stock. If you stay with stock, upgrade to 1.4.3 (you can get a CWM flashable version by looking in my tips thread linked in my signature) and root with Manual Nooter. I think it is up to 5.08.20.
If you are not invested in stock, definitely go to CM7.2. It is smooth and very stable.

So I decided to go with CM7.2 but
http://wiki.cyanogenmod.com/wiki/Barnes_&_Noble_Nook_Color:_Full_Update_Guide
says it only works with 1.2. I got the link to wiki from here.
And one technical question, does CM7.2 remove original Nook Color OS completely? If so why its version matters?

Yes, if you install CMx on EMMC it will replace B&N ROM on the device.
That is an old instruction... The reason that method only works with 1.2 is because they have you rooting it and installing CWM on EMMC. By making a bootable SD and installing CMx from there, there is no reason to root the B&N ROM before installation... so you can install it regardless of ROM on you NookColor.

So I just copy the CM into the flash (that I had made it bootable with CWM) and install CM from there. I create a backup using CWM.
