is this how it should look?

solved! i used win32 disk imager and ran it as admin. make sure you put the image file in the same folder as win32 disk imager. doing this thru a virtualbox worked great.

Hey Verygreen, i'm having an odd issue all of the sudden.

Every time I turn on my nook it goes into the size-agnostic mode as if I want to flash a new nightly... yet I'm not pressing the N button, just power. Any ideas?

Edit: Just to check, I booted to the stock NC software... the N isn't stuck or anything, it's working fine there.

Edit2: and now when I boot to SD card, all works fine. so... disregard this post
[Nook Color Android Development] verygreen:
You must be running v1.2 or something like that.

bcb stuck (or deleted?) and causes eternal recovery.

typically teh recovery image would correct this, but did not for you for some reason.

boot into stock restored bcb to it's normal form. (after boot to stock recovery I would imagine)
[Nook Color Android Development] Rattor:
I'm currently running CM7.0.3 stable via SD card, which I used the 1.2.1 installer to flash. Is it possible to update to CM7.1 stable, or do I have to start from scratch using the 1.3 installer?

On a related note, what improvements does 7.1 bring to the NC in terms of performance and battery life?
[Nook Color Android Development] verygreen:
you can update installer to 1.3, and then install update to CM 7.1 from the updated installer.
[Nook Color Android Development] Rattor:
How would I update the installer without wiping the SD card?
[Nook Color Android Development] DizzyDen:
Use the update zip file in the OP

How to install a new CM7 nightly build with the microsd card in the nook

I followed the instructions using a Sandisk 32 GB Class 4 microsd card.

Worked like a charm. Thanks!

I would now like to install a new nightly build (132).

Do I need to do it using the card reader in my PC or can I download the new cm_encore_full*.zip directly in the first partition using the nook?

Can someone provide instructions on how to do it?

Thanks!
[Nook Color Android Development] cdaters:
Hey luigig, you could have just downloaded the nightly in place of the one listed in the guide and proceeded with that if this was your first time setting up the SD card.

But you can download it directly into the first partition and reboot into recovery mode, that should do it.
[Nook Color Android Development] cdaters:
Hey cybertimber2007, are you using a mutli-boot solution here, or are you just popping your CD card out to get back to stock NC?

I am looking for a way to do this without removing card, and I tried the (Multi)U-boot guide, but I cannot get that to work for me...though I have an idea...brb

Yeah, my idea did not work. I tried to change the boot order of the aforementioned guide to boot into CM7 and leave the alternate boot method for the stock NC ROM. <sigh>
[Nook Color Android Development] Character Zero:
I was able to get into the boot menu by holding the home button while booting.
[Nook Color Android Development] doncaruana:
I'm really getting into playing around with this and setting it up the way I like, etc, when it occurred to me that if I get to liking it enough, I'll want to flash it to the emmc. Is there any way to do that smoothly? Can I use the sdcard and push it across as it is or do I just need to start over on the emmc.

If I have to start over, can I save the CM7 settings and ADW settings using Titanium Backup? Or is there another way to do any of what I'm contemplating?
[Nook Color Android Development] cybertimber2007:
Nope, 1.3. Same could apply?

Nope. Keep meaning to look into that but so far what ain't boke... now once the semester starts back, I probably could use that quick switch between NC and CM.
[Nook Color Android Development] verygreen:
I guess if bcb was somehow erased, then the write I am doing to clear the "recovery" condition is not long enough.

Now the question is who removed the bcb and why
[Nook Color Android Development] pitguy3:
Noob issues....

I am using a PNY 8gig Class 4 uSD card. When I attempt to write the image to the uSD card using Winimage64, I get the following error message.

The current image format is not supported by the disk drive E:

It will be resized.

Disk is not empty, all data on your disk will be lost!

Do you want to continue?

I have continued and followed verygreen's instructions, but my Nook will not boot from the uSD card???

Just bought it today...

Suggestions??
[Nook Color Android Development] Sincitybronze:
I would really like to do this but I can't figure out how to find the location of the first partition on my phone. Is there a directory I should look for? There has to be a better way to flash nightlies than taking the SD card out of the nook, card reader, PC, etc. Or perhaps not :-)
[Nook Color Android Development] verygreen:
well, you need to mount /dev/block/mmcblk1p1 somewhere, this is the 1st partition and it's unmounted by default.
[Nook Color Android Development] doncaruana:
Had the exact same problem with winimage on a 64-bit machine.

Try using win32diskimager instead. Works perfect for me.
[Nook Color Android Development] Sincitybronze:
Thank you for the quick response. Is there an app I should use to mount that directory? Also I am really loving this SD card version of cm7. Is there any reason to install cm7 to the internal drive? Being able to access cwm recovery is the only thing I can think of.
[Nook Color Android Development] verygreen:
I don't know if there is an app, I just do it in adb shell or in terminal emulator once you become root.

The other reason and probably much more important one at that is the ability to actually remove the sd card to, you know, put some media on it or something like that ;)
[Nook Color Android Development] pitguy3:
Thanks Don! Now when I run it, it gets to "Looking for the install images... Initial install images not found. Please download it from nook.linuxhacker.ru and put on first partition of this SD card the name should start with updatei-cm and end with .zip"

Nook.linuxhacker.ru does not exist...

Again, sorry for the noob stuff!!
[Nook Color Android Development] dalingrin:
None of my SD cards are as fast as the eMMC. Its not a dramatic difference compared to my fastest SD card but there is still a difference.

Having an SD card for music storage and videos is nice also.
[Nook Color Android Development] doncaruana:
Uh oh...we're beyond my knowledge now. :) I just did this myself in the last week.

I saw where people were getting that with gapps early on. Are you getting it on the first boot? Otherwise, maybe you should try downloading another copy of the 1.3 image from the first post. Hopefully one of the others on here that's a lot smarter than me on this can chime in...
[Nook Color Android Development] pitguy3:
Getting it on the first boot...
[Nook Color Android Development] lschroeder:
Backing up with CWM nandroid is so much nicer with OS in eMMC and data, music, and video on SD card. Probably not a bad idea to keep nandroid backups on their own separate SD card.

Backing up with img file for SD card with OS, data, music, and video is not ideal or straight forward.
[Nook Color Android Development] verygreen:
ugh, nook.linuxhacker.ru is a misspelling of the url (should have been nook.handhelds.ru)

Anyway refer back to the first post about where to get the actual update-cm...zip file that contains the CM7 installation.

Then put it onto the first partition of your SD card (now that you have run it once, there are 4 partitions already and windows might not be very happy about it. Worst comes to worst you can just reimage it and then write the install image there.
[Nook Color Android Development] pitguy3:
Thanks verygreen! Does http://nook.handhelds.ru/sdimage exist also? Is that where the install images are?

I reformatted my SD card and removed all the partitions so that won't be an issue, I can reinstall it like it was the first time...
[Nook Color Android Development] verygreen:
Yes, this is the url for install images. Should be linked to from the first post.
[Nook Color Android Development] pitguy3:
Thanks verygreen! Link is working now!
[Nook Color Android Development] Sincitybronze:
To those of you who boot from the SD card, you can install the CM7 nightlies without having to remove the SD card every time. Here is what I did (thanks to verygreen for explaining that mounting is necessary):

Install samuelhalff's Nook Color UMS (http://xdaforums.com/showthread.php?t=952456)

Open Nook Color UMS (Select mount sd (1) first partition)

Click Confirm

Use USB cable to connect NC to PC

Your NC should show up as a hard drive with the boot directory visible

Download nightly and place the .zip file into the boot directory

Select unmount in Nook Color UMS

Click confirm

Remove NC from cable

Hold power button down and select reboot, then recovery

Nightly will install after reboot and then NC will shut down

Hold power button to reboot and nightly will be installed

I imagine there is an even easer way to do this but I am not ready to mess with ADB and I can't figure out another shortcut. At the very least, it's great not to have to remove the SD card from NC every time.
[Nook Color Android Development] Sincitybronze:
Has anyone been able to get adfree to work when booting from SD card? I get "unable to locate a partition to remount to write the hosts file to" when I attempt to update hosts.

Also, I know this has been asked before but I haven't seen (or might have missed) an answer. Is there a way to move the SD card files to emmc if I want to go from SD boot to booting from the internal drive or do I have to start from scratch?

EDIT: Adfree worked when I updated busybox to the latest version.
[Nook Color Android Development] nonpromqueen:
So I'm updating since it's been awhile. Has something changed with this?

I downloaded 1.3, opened winimage and clicked "restore virtual hard disk..." and clicked the 1.3 image.

It's turning my 8GB card into a 117mb card and I don't remember having this problem the last time. Hrm.
[Nook Color Android Development] dcharleyultra:
Windows only sees the first available partition, by default.

I think you just need to continue following the instructions.

[Nook Color Android Development] verygreen:
Well, by imaging the new image you effectively wiped the old contents.

If you wanted to update, you should have picked up the update.zip linked from the first post.
[Nook Color Android Development] nonpromqueen:
yeah, lesson learned. :P I usually like to do fresh installs.

Stuck at CM7 splashscreen

I tried going through all 100+ pages of this thread but I can't seem to find the correct answer. I think it may be my SD card (Wintec 16 class 4) but I though I would ask first. I followed the instructionns (generic image and the latest CM7 nightly (encore)) and reboot my week old Nook. It gets to the CM splashscreen but just loops there. I let it go for 10 minutes but no change.

Should I try another card or is there something else I could do. I really want 16GB as my other alternative is 8 (Sandisk class 4).

Thanks.
[Nook Color Android Development] slider2828:
Just wipe the card again and try again...
[Nook Color Android Development] oiler_head:
I swapped out the 16 for the 8. Success!

I guess the I/O errors really meant something. Too bad that SD card speeds are so important. Can I try to image the 8 and lay it on the 16 CB card? Curious...
[Nook Color Android Development] doncaruana:
Conventional wisdom around here is that Sandisk is about the only card that reliably works with CM7 because of the random r/w speeds. I had a 16GB class 4 (Patriot) and had FCs and other issues, switched to an 8GB Sandisk class 4 and smooth as silk. Beyond that, I think you can use something like easus partition manager to extend the card, but I don't know how.
[Nook Color Android Development] dcharleyultra:
My 16GB class 4 Sandisk works fine too.

[Nook Color Android Development] slider2828:
I mean you might be able to spring for a cheap 16gb class 10.... Remember you are running an OS off a floppy.... so it makes a huge difference.
[Nook Color Android Development] DizzyDen:
Yes... you can try just imaging it over and test it.

I had experienced initial install issues on a 16 gig uSD but it works (reasonably) well with an install imaged over to it... I keep a version on it just for playing around reasons.

SDCARD issues, nightly suggestions?

I have installed SDCARD image and setup on 3 nooks now, 2 sandisk 8gb class 4, and 1 sandisk 16gb class 4. Only problem I had was one of the sdcards had been previously setup with multiple partitions. I use Easeus partition program to delete all partitions before imaging the cards.

I have the RC7.1 installed,

anyone recommend a nightly to update to? So far all are working perfectly!
[Nook Color Android Development] zombieflanders:
What method did you use to image over? I'd like to avoid having to TiBackup and restore as much as possible.

[Nook Color Android Development] bweisholtz:
two things. first off, thanks for this. it was crazy easy and works beautifully.

next, i had a spare Sandisk Class 2 8GB card lying around and decided to give it a go on that before purchasing a new, higher class one.

to my surprise, it's running as smooth as butter on this class 2 card. i overclocked the NC and it's straight up awesome.

So if anybody wants to try it out with a lower class card, just know that 1 person around here has great results with it.
[Nook Color Android Development] cdaters:
So I'm hoping someone can direct me in the right direction...

I wasn't thinking when ROM Manager notified me of the 133 nightly update when it became available (I was then running 132). So I tapped on download, then install...

The update started, then my NC shut off. When I restarted it, it no longer boots into the Alternate bootup which was then CM7 (on the uSD). My primary was stock NC ROM (on the EMMC). I can still use the boot manager (pressing "n" just before "Loading...") to boot to either or, so I can still use my CM7 install no problem, it is just my alternate boot via both-volume-key-press that is broken.

I then updated to 133 when it became available "the right way" hoping that would fix my issue, but it has not. I still have to use the main boot manager to choose which way I want to boot (uSD or EMMC). I see that 136 is now available and I will update to that shortly, but I was wondering if someone can help me repair my primary or alternate boot...?

Before I broke it by trying to update from ROM Manager, I had used Nook Tweeks to set my boot scenario, but going back to use Nook Tweeks to fix it is not really fixing it :)

[Nook Color Android Development] Character Zero:
I am finding the boot partition to be almost too small. The newest CM7 nightly barely fit. How can I make it a little bigger? I am using OSX.
[Nook Color Android Development] verygreen:
I also posted a mirror of the installer files at http://crimea.edu/~green/nook

Should work for now while I am working on a more robust hosting solution.
[Nook Color Android Development] verygreen:
This is not all that easy and the boot partition is a dead weight when you are not installing updates, so I am thinking of perhaps allowing updates from the 4th partition (from a special dir or something).
[Nook Color Android Development] sdhotwn:
This should be the world's simplest install but I'm getting nowhere. I'm trying it with a Sandisk 8gb and 16gb class 4 cards. Putting the cards in my laptop, opening the 1.3 image in WinImage as an administrator. Selecting all files (4) and writing to the disk. I am getting the "current format is not supported... will be resized" error. I click okay and it quickly writes the files. I eject the sd, put it back in the laptop, move over the CM7encore_134 nightly (shows up in the same area as the 4 files that got burned on) in it's as downloaded form. Eject the disk... pop it in the nook, and power it on. I get the "read forever" splash and then it goes to the n splash and then right into the main OS. Every time... no idea what I'm missing.
[Nook Color Android Development] doncaruana:
Are you maybe running on Win7 or Win7x64? I had that issue where Winimage would burn, but not boot for me. Try win32diskimager instead.

Hi, y'all. Just wanted to confirm this: what does 'size-agnostic' exactly mean?
[Nook Color Android Development] doncaruana:
Some of the early images were specific, ie "this is a 2gb image", "this is a 4gb image", etc. This image can be used on any size sd card and will just automatically resize to work.
[Nook Color Android Development] lschroeder:
Special directory sounds good. Kind of the approach we used before automount of USB flash drive/fat 32 drives were available.

Could you use the same scheme as you have now. Deleting the update, gapp, and Dal's OC zips. This is two fold, we save the space plus we have visual proof that the install was executed.

Could you also keep Dal's OC install when you change the current version. I use your current version for the nightly, older phiremod's, and MIUI ROMs. I know the newer CM7 nighlty has the OC built in but for some of my use I still use the install of Dal's older OC's. It would also be necessary to reinstall any nightly before 132 if OC was desire.

This installer and Dal's OC are my two most used nook color items. A hugh thanks is in order to both of you.

Can I use this img to flash this: [ROMS]Dualboot Phiremod / Honeycomb Image for SDcard [UPDATE-6/22] (from http://xdaforums.com/showthread.php?t=1045018)

And also, does it mean that if I installed that, I would have 3 ROMS running in my nook? Since I have a Cm7 nightly 136 in the eMMC, then this install is on the microSD, right? Please confirm? Thanks!
[Nook Color Android Development] verygreen:
I cannot easily preserve older kernels because the installer has no way of knowing your intents.

the full nightly update is like any other update, and if the update supplies a kernel, it replaces the kernel, if the update does not, the installer does not.
[Nook Color Android Development] lschroeder:
Thanks for the clarification.

Edit: "If the update supplies a kernel, it replaces the kernel." This means for a new nightly the kernel will be replaced automatically. If a ROM such as phiremod's is based on a 132 or above it will automatically get the kernel updated. So I guess their is no problems with ROMs based on 132+ nightly automatically getting kernel updates.

Total N00b help needed

Hi Guys,

I used the image, followed all of the directions and have a very functional and pretty CM7 Install on my 1GB SD card. Now that I have made the changes that I wanted to and have decided to settle with this ROM, how do I take this working image of CM7 and copy it over to an 8GB card that I have available. Is this possible?

TIA for helping a girl out =)

[Nook Color Android Development] Crazydaddy:
Are you supposed to get a long list of I/O errors when its setting ups cm7?

8 gig class 4 card.

Well it must not like Dane Elec sdhc cards.....the script runs, says its installing stuff....has a ton of I/O errors....says its complete then shuts down. Reboot with the card in, I get Cyanogen loading....then the nook boots as usual.

This is a brand new 1.2.0 nook color.

Edit ......it now boots to the cyanogen boot animation but it will stay in a boot loop until I power it off. Grrrrr

Hi All,

I dunno if this question can be posed in this thread, but I think this is related to CM7.

I am unable to put any image, other than Cyanogen in-built, as wallpaper.

When I long press on the "desktop" and select, wallpapers, I try selecting a wp i downloadedn thru gallery. First a resize image box is shown. I straight away select save....and then.....nothing happens...

The screen again shifts to the same image. When i go back to the homescreen, my previous wallpaper is still there.

So, is it possible to put an image of our choice as wallpaper for CM7?
[Nook Color Android Development] sano614:
I'm not sure if it's me, or what... I haven't messed with the Nook in a while, and I'm trying to get CM7 on it on the SD card.. I apply the generic-sdcard-v1.1.img while the SD is in the Nook (also tried it in the PC) to the SD card by using win32diskimager, and that goes fine. I then try to add the CM7 file to it but I get a message from Windows (and the Nook if I plug it in there) that the card needs to be formatted...

I've tried several different SD cards, but nothing is working.. I was able to get the HC sdk port working when that first came out.. But I'm stumped with this.
[Nook Color Android Development] DizzyDen:
You cannot write the img files while the SD is in the nook... you have to use a card reader to place the SD in and write the image to the card... with it still in the PC you should see the partition called boot in windows explorer... copy the CM7 zip file to that partition.
[Nook Color Android Development] sano614:
Yeah I tried it in the PC as well.. Used the card reader built into my laptop with Windows 7. As soon as I write the image file, it tell's me windows needs to format it and I can't find the boot partition anywhere..

edit - got it now!
