I just received a new NC last night and have been playing around with modding it. I started with 7.0.2, then realized 7.0.3 is better and installed it. I couldn't get overclocking working on the updated build and was limited to 925MHz. I then came across this thread and through I would try it.

So far I have done the following...installed cm-encore-full-86.zip and also grabbed the 2.6.32 kernel from May 13th. After reloading everything on my NC I can see the Android version is now 2.3.4, the kernel is 2.6.32.9 and the mod version is listed as CyanogenMod-7-05252011-NIGHTLY-encore.

When I check the CM settings for Performance I am still limited to 925 MHz as the maximum. Any ideas why it won't let me overclock?? From what I can see, everything has been downloaded properly.

Thanks...
[Nook Color General] greenmky:
So the steps to upgrade to a nightly say:

Install zip from sdcard, flash the new nightly .zip and/or then the OC kernel .zip if you're using it. (If it's the first time you are using a new nightly from 80 onwards you'll need the uBoot .zip (see post2))

But I don't see anything on post 2.

I've been following development threads but I'm pretty new to this...so just checking.

I'm on the stock 1.2 uboot. Do I need to also flash the new uboot? Or no? From the development conversation I've seen, stock 1.2 is fine - just checking? Or are there instructions on flashing the new uboot I'm not seeing?
[Nook Color General] GSUBass05:
nightlies 86 and higher have a new uboot included. If you install one of those you won't have to worry about messing with uboot.

They changed the image it's a small green background that says cyanogenmod when you first boot up instead of "read forever" or "touch the future of reading"
[Nook Color General] I Am Marino:
I noticed this, I was confused at first.

I realized what it was after a 2nd reboot.
[Nook Color General] eyeballer:
Sorry about that, I thought I'd caught all the uboot stuff, fixed now.

Thanks for posting.
[Nook Color General] GSUBass05:
eyeballer,

I just want to thank you for the guide that you've put together. I've been updating nightlies about once a week now after going from AutoNootered 1.1 to CM7 Nightly 72. Before I started doing this I was paranoid about installing new roms or seriously tinkering with a device.

Up to Nightly 87 w/ Dalingrin's latest kernel. This thing flies. Your guide is stupid simple to follow and the work of all the dev's have made this tablet a steal at $250.

So I guess thank you to all the dev's that work hard on getting everything running smoothly as well.
[Nook Color General] greenmky:
Your guide is awesome and super useful for those of us fairly new to Android ROMs. :D

I'm going to go to the new nightly as soon as they post it tonight ;)
[Nook Color General] delosh:
Working wonderfully

Flashed nightly 86 + the 5/23 OC kernel earlier today. Wonderfully snappy and stable at 1200 MHz, wifi is working well, not a single freeze-up or force close, and video works as well as or better than it ever has in Opera, YouTube, and Netflix.

Really sweet how things have come along.
[Nook Color General] nolook:
great guide...i I flashed build 87 today with latest OC kernel but can only see Max 1.2 ghz? is this the max limit currently?
[Nook Color General] I Am Marino:
Yes it is.
[Nook Color General] angomy:
It was an absolute breeze to install n87 on EMMC thanks to your guide. I've got that post and the recovery -> stock 1.2 unrooted linked post archived for future reference.
[Nook Color General] butler360:
Is there anywhere we can keep track of the work being done to get this working on the new partition layout?
[Nook Color General] capidamonte:
Awesome guide

Just saying thanks, bought a used Nook that had some sort of NookieFroyo on it, that was pretty stuttery.

CM7 Nightly 87 and the OC Kernel, and this is a fine little machine.

Your guide was a huge help.

Aloha!

Can you confirm if the kernel you flashed was the 23/5 one? The one named 'update-CM7-dalingrin-OC-emmc-052311.zip'.
[Nook Color General] nolook:
yes thats the one i flashed...
[Nook Color General] eyeballer:
1200MHz is the max OC on the .32 kernels AFAIK. It runs very smoothly so don't worry about the numbers.
[Nook Color General] Hosermage:
Hey eyeballer, would you mind updating the OP to point the new partition (blue sticker) owners to the thread that teaches them how to repartition the NC?

http://xdaforums.com/showthread.php?t=1094371

I just recently got a NC with the blue sticker and I was able to repartition and install CM7 perfectly, so the big bold red text on the top of the OP no longer applies.

Just wanted to save any future NC owners from the confusions that I had.

Thanks!
[Nook Color General] eyeballer:
You read my mind. Updated the OP, however soon with the new CWM this will be a non-issue.

Nook Color not booting from SD!!

Hi I can't get my Nook Color to boot off the SD. I made a bootable clockwork SD from a class-4 Sandisk SDHC card. Is the class-4 a problem? I did read somewhere that you need a class-6 or higher? What SD cards are you guys using?
[Nook Color General] Jimbo67:
The card you are using should be fine, as that is what is recommended.

Are you sure that you burned the .img file to your card?
[Nook Color General] hungryTux:
I did. But I burnt the 4 gig image instead, since I'm using a 4 gig card. Should I try a different image?
[Nook Color General] Jimbo67:
Try the 1gb size CWM image.
[Nook Color General] TubeShaped:
What tool should I use on ubuntu linux to 'burn' the image to the sd card?
[Nook Color General] hungryTux:
Yea will try that! Don't have the card-writer with me at the moment..will let you know how it goes. Just hope my NC doesn't turn out to be one of those odd-balls which dont boot of the SD card. Is there a way we can verify that the image burnt correctly on the SD card, before we actually plug it into the NC?
[Nook Color General] hungryTux:
On the command line run the following command:

dd if=<clockwork.img path> of=/dev/<sdcard> bs=1M

run the 'df' command to find your SD card partition.
[Nook Color General] Jimbo67:
I asked this very question when I burnt mine:

Hey guys,

When I extracted the .img file for clockworkmod, it was in the neighborhood of 900mb. When I burned the .img to my sd card, it burned 4 relatively small files.

mlo 15kb

u-boot 281kb

uImage 2,174kb

uRamdisk 1,258kb

And this is what it should be on your card.
[Nook Color General] hungryTux:
Ahh just what i wanted..alright will check this with the 1 gig image. Thanks!
[Nook Color General] capidamonte:
I did precisely that, but it turns out that you want to burn the image to the whole device, not the partition.

ie: /dev/mmcblk0 not /dev/mmcblk0p1

(The above assumes that path for your sd card -- check it yourself with df!)

Won't boot otherwise.

Aloha,

[Nook Color General] rog152:
Okay, I need help

I have CM7 7.0.2 installed on eMMC all is good OC at 925

I use Rom Manager to update to CM7 7.0.3, then CWR to install gapps, then the OC kernal

All is good untill I try to overclock to 1200 or 1300, nook looks up.

I have install the OC kernal through CWR and the kernal updater app

Any ideas?
[Nook Color General] Jimbo67:
Be sure that you are using the ext4 kernel for the stable version of CM7

Some folks have had issues overclocking their NC's to that range--research around the forum and you will find threads about this. It seems that due to variations in the NC cpu's, that some can't handle the overclock set that high.

Hope this helps :)
[Nook Color General] rog152:
Thanks but I am using the one in the OP thread, isn't that the one I should be using? Also, why do I need to reflash the gapps?
[Nook Color General] Jimbo67:
Yep, I checked the link, and that is the ext4 one for cm7 stable.
[Nook Color General] eyeballer:
I think your nook just can't handle the higher clock speeds. Stick to 1.1ghz and you'll be fine.
[Nook Color General] rog152:
I understand and do not understand, why can some nook's OC to 1.3 and others cannot. I bought this one first day of release.

And which one has the 1.1 clock speed for CM7 7.0.3?
[Nook Color General] I Am Marino:
I've read it before, don't remember where though.

For whatever reason, some are just different than others, so slightly that some can handle it, some can't.
[Nook Color General] hungryTux:
No still no luck! Not with the 1GB image either! I dont know what I'm doing wrong here. My NC just wouldn't boot from the SD card. I was on 1.2. I even went back to 1.1 with the 8 failed reboots method to see if that worked. But no that didn't help either. I'm using a Ubuntu (Natty Narwhal) machine to burn the sd card. Here's the details:

[Nook Color General] greenmky:
All CPU overclocking is variable. Not all chips can do the same speeds on the same voltage.
[Nook Color General] hungryTux:
Now booting from uSD!!

Never mind, I got it to work after burning the image using Win32DiskImager on a Windows machine. Pheww..what a relief, i thought I had one of those defective NCs. But this is weird, the NC seems to have a liking for images burnt with the Win32DiskImager than the ones made on other OS'. See this post - http://xdaforums.com/showthread.php?t=1096865

Alright..time to taste some CM7 goodness :D
[Nook Color General] pdagenius:
Awesome guide and the most thorough I have seen in my reading round in advance of my Nook arriving in a day or so and zapping it with CM7.
[Nook Color General] RoboRay:
Random variation in quality of the chips. Google "overclocking" and "chip binning" for details.
[Nook Color General] ruggles531:
I have been encountering difficulty in getting my NC to overclock. I originally installed 7.0.3 and the OC kernel from 0424. I used CWM to install the core file, then gapps, then the OC kernel. Upon booting up I could only OC to 925MHz and the kernel still seemed to be listed as the original.

I then installed cm-encore-full-86.zip and also grabbed the 2.6.32 kernel from May 13th. After reloading everything on my NC I can see the Android version is now 2.3.4, the kernel is 2.6.32.9 and the mod version is listed as CyanogenMod-7-05252011-NIGHTLY-encore.

When I check the CM settings for Performance I am still limited to 925 MHz as the maximum.

Any ideas why it won't let me overclock?? From what I can see, everything has been downloaded properly, but I don't think it's installing the OC kernel properly...even though CWM gives a successful installation message.
[Nook Color General] ruggles531:
Still trying to sort my issue out with the kernel install...

I've tried a couple more times today, copying the new kernel to an SD card...booting CWM on the SD card and selecting install from ZIP. The on screen messages indicate the kernel was updated successfully, but upon booting the system the kernel is still listed as (2.6.32.9 erik).

Is there a different way to get the kernel installed on the system? I have seen some people mention extracting some files from the kernel ZIP file and overwriting files in the CM installer ZIP file, but I'm unsure which files need to be extracted and overwritten.

Any suggestions??
[Nook Color General] stolenmoment:
There's the problem. .img files should get dd'd onto the drive, not the partition. Use /dev/sdb without the number. The 'b' might be different next time.

Also, umount the drive after you insert it.
[Nook Color General] flu13:
Can anyone help me? I have tried to read up as much as possible before attempting this, and today, I got everything in place and decided to start this process.

Step 1, download CWR and write it to my SD card using WinImageWriter. Well, the img file is 14.9 GB, and my 16 GB SD card claims to have 14.8 GB free space. So when I try to write the image, I get an error that there is not enough free disk space.

What do I do?
[Nook Color General] flu13:
Ohhh, wait a sec. I think I might have solved the problem by using WinImager instead.
[Nook Color General] flu13:
Nope. :/

Failed to boot into recovery, and just started up normally. I would love any and all advice.
[Nook Color General] LongbowFoSho:
I'm perplexed about how you could possibly get an image file that's anywhere close to 15GB.

I'm no expert, but are you running WinImager or WinImage as an administrator?

To the OP, many thanks for this guide. I haven't been tweaking with mine for the past month or so because it was running so well on CM7 stable that I'd forgotten how to do everything once I decided to try the new battery-friendly nightlies. This guide totally saved my ass.
[Nook Color General] flu13:
Well, the thread here has files for 128 MB and 1, 2, 4, and 8 GB. It states that there is a 16 GB version on RapidShare, but that it was too large to post here. I got that file, because it's my understanding that I should choose the file whose size matches my SD card. Is that not the case?

And yes, I ran as Administrator, or so I believe.
[Nook Color General] tiffanydawnn:
You can use the 1gb image on any card. I believe it says that in the OP. I used the 1gb image on an 8gb card with no problems.

Well, I seem to either have a bad SD card or a bad version of Windows (more likely). My only PC I have access to right now with an SD reader has Vista. I can't get Win32DiskImager or WinImage to properly write the recovery to my card. The former, no matter the size of my image, tells me that the disk doesn't have enough space. The latter appears to sort of work, but only takes like 2 seconds and I actually see files on the card, but the Nook won't boot into recovery. I've made sure that for both, I'm running as Administrator.

Anyone have any advice?
[Nook Color General] flu13:
Found info on a bug here that seems to be exactly what I'm running into. I'm trying to get myself to a point where I can rebuild the source with the patch added.

I also tried using flashnul to write the image from the command prompt, but I get a message saying: "DeviceControl() / IOCTL_STORAGE_QUERY_PROPERTY (adapter) failed: Incorrect function." Below, under adapter and device properties, it says Command Queue: Unsupported. I don't know if that last part matters or not.
[Nook Color General] RoboRay:
Try a USB card reader. Built-in SD readers often have problems writing bootable images.
[Nook Color General] flu13:
Doh. I don't have a card reader. But at least that gives me some hope. Thanks.
[Nook Color General] flu13:
Woohoo! Quick trip to Walmart later, and I'm finally burning this darn image. Thanks again for the pointer, RoboRay. And in honor of your avatar, "I'd buy THAT for a dollar!"
[Nook Color General] flu13:
Argh! I can't get anything to work properly.

Now, I'm in recovery, and things seem cool. But when I go to apply zip from sdcard, and select "choose zip from sdcard," it just tells me, "E:Can't mount /sdcard."
[Nook Color General] flu13:
Not sure what I did, but it's better now.
[Nook Color General] flu13:
*sigh*

I thought I was finally doing well. Flashed everything, and after I did the factory wipe/reset, CWR sort of froze up on me. I couldn't navigate at all. I went ahead and popped out my SD card and reformatted it in my PC. I then booted the Nook, and saw the Cyanogen logo, then, in landscape view, saw A N D R O I D in the lower-left. After a few seconds of that, I get what appears to be a cursor in the upper-left, and it just sits there.

Help?
[Nook Color General] christoophat:
I just "un-rooted" my NC (1.2.0) to stock (the 8 reboot method). Notice that it is now reverted back to 1.0.0 FW.

Do I need to update the B&N fw to 1.2.0 FIRST before installing CM7 as in the OP?

update: Went ahead & installed the 1.2.0 update then installed CM7 87 nightly, gapps, & the 052311 dalingrin OC kernel

Everything when as described in the OP. Many thanks for the guidance here!
[Nook Color General] christoophat:
Seems now that I have lost USB connectivity after the CM7 install. Cannot see unit/SDcard nor transfer over any files when connected to my Win7 PC.

I've read elsewhere that an OC kernel can be a cause?

Any way to fix this?

update: Saw last night where the recent nightlies all have the same USB issue.

Can I reflash to the Stable 7.0.3 build and matching 0423 OC kernel over it, or do I need to do a full wipe first?

Anyone?
[Nook Color General] Jiggity Janx:
If I could recommend, under the "Updating to a newer nightly build or kernel" section adjust number 3 to add wipe dalvik cache along with "wipe cache". Your first section talks about installing one of the stable builds and a dalvik wipe would be needed to go to a nightly and/or back.

Thanks for pulling this together.
[Nook Color General] akenis:

Need some OC info

I followed the OP guide and installed the 87 nightly to take advantage of the fixed sleep issue. Everything works great.

I wasn't sure, however, which dalingrin's OC kernel to use. Do I need the OC kernel to OC? Which one should I use? Will it break the sleep fix?

Can I just overclock the the CM7 .32 kernel directly in CM7? Any recommended settings?

Thanks.
[Nook Color General] johansolo:
Similar story here, except I get to the blue Cyanogenmod Android... but the thing just sits there with an arrow spinning around it to eternity.
[Nook Color General] flu13:
Well, I figured out that my problem was that I had an incompatible CM build and OC kernel combo. When I retried with nightly 87 and the 5-23-11 OC build, it worked.
[Nook Color General] akenis:
Been pulling some hair out here. Boot into CWM fine and flash latest nightly and dalingrin. CM7 starts up with android.process.media fc repeatedly. I don't see a status bar or notifications, so I'm having a hard time moving around here.

I used the ROM manager in the nightly build to install CWM to EEMC. I've booted into that several times to factory reset and clear dalvik. CWM freezes, and holding power button down for a while will eventually power off. My data persists somehow?

Tried booting from the SD again, skipping dalingrin. Freeze with dalvik clear. Same thing start.. fc on android.process.media, and my data is still there?

Just bought this yesterday. She offered me a blue dot, and then said we've got some of the old ones they just found in a stack. I think it said 1.2 for the brief time I had stock running. How can I tell if I've got the old partitions? Storage settings read:

Internal storage total 5.09 GB

Additional /mnt/eemc 1 GB

... guess I'll go check that first post!
[Nook Color General] martian21:
Sounds like you need to format /data /system and /cache in Clockworkmod (advanced menu I blieve) then re-install CM7, gapps, and overclock kernel (if you desire).

NOTE: THIS WILL WIPE ALL YOUR DATA - YOU HAVE BEEN WARNED!

Also,

Do NOT format the /boot partition
[Nook Color General] flu13:
I was getting the same. Never solved it. Loaded Phiremod instead, and I'm a happier man.
[Nook Color General] akenis:
Post two talks of data and media partitions, so I'm not sure which is which?
[Nook Color General] akenis:
Tried that (with the same images, which did checksum). Doesn't seem right that CWM freezes after the wipe. And I've seen CWM say data/cache formated, and yet it still knows my Google account stuff... haven't seen the welcome to Android screen in a while...
[Nook Color General] akenis:
Actually didn't try format from advanced. Restored stock from tho and had "error formatting data" msg.

Booted with "read forever".. and new setup. But the keyboard doesn't work right.

Did someone forget the blue dot here???
[Nook Color General] akenis:
Well thanks for the noob help!

Some idiot forgot the blue dot I guess. Did repartition:

Internal storage total .92 GB

Additional /mnt/eemc 5.23 GB

So Data = Internal

Media = /mnt/eemc

CM7 makes a bunch more sense with the status bar and menu available!

Great guide, but don't rely on the blue dot!

And AVG flagged that hash checker as malware...

Still have to repartition blue dot

I'm getting errors when I try to format /data with 3.2.0.0. I also get an error at the /data partition when I try to restore a backup.

It does seem to delete something from the /data partition. Restoring /system gives me a working CM7. (I have to setup/sign in to Android again and my apps are gone.) But space isn't being reclaimed from the /data partition. Reinstalling my 200 megs of apps from the market results in 400 megs of used space on the 5gb /data partition.

I can't post in the dev forums since I'm a new user, so I hope Nemeth sees this.
