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!!

Although I haven't installed Alsa, I doubt that the order matters.

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.

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?

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.
OP Modified question to be better suited, new response to match:

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.

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
I can't find a definite answer for upgrading from 7.0.2 to 7.0.3 stable. I did a tatanium and clockwork back up just in case. Have the latest clockwork recovery. But when you boot into recovery do you first wipe system then cache, installed built, then wipe dalvik then reinstall latest gapps then 4/24 OC kernel? Are those the steps? I just want to male sure that way my apps don't get erased. I'm installing to internal memory.

I would not even update to 7.0.3 to be honest. I'm assuming you are running 7.0.2, so I would download nightly 69, the fixed OC kernel (not the one you are used to using..it needs to be the ext4 one which is available by reading through the notes on the overclock kernel page over in android development...head towards the end of the pages), boot into recovery, flash nightly 69, flash gapps, flash OC kernel, Wipe Cache, Wipe Davlik, Hard reboot...and you're good to go

Why would you recommend against 7.0.3?

Well cm7.0.3 runs off of android 2.3.3. The newer nightlies run off of Android 2.3.4 which is going to be what CM7.1 is going to run off of. Both of my nook colors have run cm7.0.3 and one of them had issues (as have a few other people) while the other one ran okay, but the nightlies continued to out perform the cm7.0.3 hands down. Not only that, the newest nightlies getting incredible battery life compared to what cm7.0.3 had. In a test I ran, I got 2 hours and 6 minutes more battery life off of nightly 67 compared to cm7.0.3. It is just a personal preference, but if the option for a newer OS is available, why update to something that is older?
Well, because stable is...stable. I certainly haven't had any issues with 7.0.3 under very heavy and varied use, whereas the nightlies have their share of issues (not to mention an obvious absence of 'real' overclocking), some of which appear to not be common knowledge despite a great many attempts to make them so. =)
Certainly, if I were recommending to a daily user, I'd advocate 7.0.3 over even the latest nightlies, if for no other reason that (once properly installed) it 'just works'.
It's not even clear whether the 1.2 u-boot can be used with the newest kernel betas when booting directly from a SD card, which in and of itself is a major blocker for me (using verygreen's SD image).
I suppose it comes down to personal preference, but again, I'm unaware of any significant outstanding issues with 7.0.3. If someone's having issues, they should by all means ask for help if they don't want to dip their toe in the unstable pool.

The 1.2 u-boot has to do with the 2.6.32 beta, not the nightlies. I am and have been overclocked on all the nightlies since 59 when they first made the switch to 2.3.4...I have had no issues with any of the nightlies at all, but if you're an average user, then go with 7.0.3...like I said before I just don't see the point in flashing something that is already old compared to what is available and very stable. And why are you still using an SD card? Flash to stockkkk =) and for now, I think I will continue to swim in the stable pool.

I dont need the latest nightly i just want something stable since i use my nook everyday. Battery drain isnt an issue for me since i go the whole day with out having to charge it. So if i decide to use nightly (69) you have to use "ext4-CM7-dalingrin-OC-emmc-042411". Is that the same kernel i have to use if i decide to use 7.0.3? or should i just use "CM7-dalingrin-OC-emmc-042411"

If you use nightly 69 then yes you need to use the kernel you mentioned above. If you use cm7.0.3 then just use the regular overclock kernel. And nightly 69 is very stable. I have been running all of the 2.3.4 nightlies and they run smooth as butter for me.
im going to use nightly 69 heres the kernel for anyone else interested in upgrading

good choice and good luck
There is a misconception in this thread......Your kernel selection has to do with your version of Clockwork Recovery. The latest version of Clockwork Recovery will only boot with a kernel that has had an ext.4 script change. Older versions of Clockwork use the "original" kernels found in dalingrin's kernel page. To eliminate anymore problems or confusion. If you have not updated CWM please do so, then update your kernel to the one with the script change attached to this post. Both SD & EMMC versions are attached.....All will be right with your Nook
I upgraded from 7.0.2 to the nightly 69. Everything went fine, but I no longer have USB connectivity. Any advice on how I might get it working?
I use swiftp to transfer files over Wifi from computer use firezilla or any other ftp program to make a connection. I think it's a bug according to what I read on another post...
That works just fine. Thanks.
I have 7.0.3 running from SD card.
I tried putting the 0424 OC on and found it seemed to be causing a problem with at least one program, LCD Density after I increase to 1200. When I ran the app to increase my icon size it would freeze up the NC and only way out was a forced reboot.
Anyone else find problems like this and is this unusual.
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.
I will be getting a refurbished Nook Color this x-mas and had a couple questions i need to ask before i root and install cm7. My first question is should i update the stock firmware to 1.4 prior to rooting? Secondly, If i so update to 1.4 should i still follow Eyeballer's guide to root my NC or do i need to find another guide?
You do not need to worry about the 1.4 update. If you run CM7 off either a SD card or internally it doesn't matter. When you boot to a card it does not see the stock ROM. If you run CM7 from the internal eMMC you will be replacing the stock ROM anyway....
Thanks for the info!
I do have another question, i have seen tutorials talking about installing Dalgrins overclock kernel, do i need to install this with the newest CM7.1 mod?

Hey guys. I just rooted, flashed a new ROM ( newest CM7) onto my p970 last night, so yeah, I'm a total newb and so much confused about these things. Apparently I saw a thread about kernels and that they kinda improve performances and stuff, so I tried installing them. And now my phone is in boot loop state and I can't boot CWM to reflash the original kernel. I used Huexxx's kernel from this thread.
http://forum.xda-developers.com/showthread.php?t=1332311
So I'd be really grateful if someone could link a thread on how to fix this, or a step by step guide. And I'm totally new to this forum so I'd like to apologize beforehand if I break any forum rules and the likes. Thx.

* nvm, I somehow was able to boot into CWM from the boot screen and then I just reflashed the current ROM. Thx btw
What has happened to you device? Bootloop? DO this: http://forum.xda-developers.com/showthread.php?t=1275315 AND READ my NOOBGUIDE!
You have to flash a new software, root it, install CWM and then reflash CM7 WITHOUT KERNEL! There is none working at this time. Although Nova 12 is planed for it
-edit- woops read your edit too late...

| Thx for the reply, really appreciate it. Man there are a lot o' things I need to learn
| btw, if you don't mind answering, it seems that the phone gets real laggy after a an hour or so of turning it on. I've checked the apps and made sure that none are eating up the phone's memory. Is it just me or does it has something to do with CM7?
Hope you dont use any memory cleaner or other "tuning" software, since this mostly only messes the phones up... Mine runs fine, so I guess it is a problem on your side. I always recommend fix permission from within RomManager, cause it often solves/solved problems. I also always move all apps to SD card, inside of App Manager (the stock one, not anyone from market) cause it saves space and resources for the phone.
Did you mess around with cyanogen settings? Which governor do you use? Maybe use SetCPU or NoFrills or similar? If so, uninstall it.
Simply list all your apps, if none of the given tips helped And do a reboot all couple days, since it seems to be good for the phone
