(How To) CM7 Bootable SD

[J515OP]

im having trouble burning the first disk image to my SD card.

I open up win31 disk imager and go to the folder where I saved the file, but it wont show in the program.

When I navigate to there w/o being in the disk imager program it shows up fine.

What am I doing wrong?

The image file must be unzipped before it can be burned. The ROM and GApps should stay zipped though.

Ok, it worked. Just to try it out, I backed up Angry Birds- Regular, Seasons and Rio. Following your instructions, I was able to restore Seasons, about to restore the other 2 now. This is going to be quite time consuming to do my 100+ apps. Any tricks I'm missing to make this easier?

You can run the process as a batch instead of doing one at a time.

thank you I will try to unzip it (it didnt show up as a zipped file though so I was confused).
I probably did something wrong.


anyway last night after that didnt work I went to Barnes & Noble Nook Color: Full Update Guide - CyanogenMod Wikiand tried it that way...
got to the part where you add the cyanogenmod rom to your nook...and it didnt show up on the nook. then I tried to use the back up I had created and it didnt work, now im stuck in a boot loop.

Its weird though, because the unooter they had there, when I burned it to the SD, it made three partitions.
One with the Unooter thats only lie 39MB, another small one, and one thats unformatted or unusable.
so all I can do is add stuff to that 39MB partition. and whats crazy is it wont format the SD on my windows machine (it does work on my mac however)

any ideas whats going on there?

anyway im following this thread

http://theunlockr.com/2011/02/14/how-to-restore-the-nook-color-to-stock/

and ive downloaded the right size, extracted it. but when I try to write it to my SD card it always stops and gives me an error about not being able to find a file (error 2)

 

[jealousblues]

ok, with the 8 GB file it would never work.

I finally tried out of desperation the 1GB (on my 8GB card) and it eventually worked after erroring a couple times.


now take two on CM7

thanks for the help so far guys!

This is standard and how the size agnostic is supposed to work. You actually end up with 4 partitions, boot, system, internal memory and whatever is left over as the "sd" card. The first two are supposed to be small, the partition designated as internal memory (from the ROM on the SD card's point of view) is about 1GB and the remainder for the size of the card you are using is allocated to what the ROM on the card sees as the SD card.

Your PC will only see the boot partition and this is ok. Also the PC won't recognize the partitioning or formatting of the card unless you have a special partitioning program but this is ok too. All you need to do is place the CM7 zip file and Google apps zip file in the boot partition.

Once you insert the card and CM7 installs (installation is first time only) the partitions on the card will be visible to the Android system. If you connect the Nook to the PC while booted into CM7 (USB or Samba) the PC will see the internal memory partition as well as the the sd card partition so you can add or remove files via the pc (music, books, movies).

To J15OP,

This is actually my first time posting to a forum...I'm usually just lurking, searching for answers ;-)

Anyway, I have the NOOKcolor, and have been searching EVERYWHERE for some clearcut, step-by-step instructions that are at least somewhat easy to follow. I am an IT student (hense my forum name lol), but I AM new to rooting devices and things like that.

Getting to the point, I just felt a strong need to let you know that you've provided the BEST instructions thus far! Things worked perfectly, I was able to get to the links you provided, which were also right to the point...in other words, the downloads on your links were right there - no need to browse through a bunch of other forums to find exactly what I needed! That has been one downfall of my search until I found this one.

Also, the CM7 itself is REALLY nice!

Again, thanks so much for your awesome information!

Thank you ITs and welcome to the forum I am glad you found the instructions helpful. Be sure to browse around now that you are here. There are many other threads chalked full of good info and good people.

Ok, I followed the directions on page 1 with a freshly formatted (by Win7) 16 gb card. Setup seemed to run fine. When I restart, it just runs setup all over again. I can't get it to boot CM7. Any ideas what might be wrong? My Nook is a fresh refurb on 1.30, nothing has been done to it.

More info- I used the generic 1.3 img file, unzipped, along with CM 7.0.3 Encore and gapps (both zipped on the SD card). I used 7Zip to open the image file, Win32Image to write the card. I have tried 3 different cards (2 gb, 8gb and 16 gb), full formats on the SD cards using both Win7 to format and also using SDFormatter. I have also tried it with and without the gapps file on the SD card. I still get the setup program running each time I power it on, it does not boot CM7. This is really getting frustrating since the stock OS is so weak.

scottz, try the older version of the img file. Also with Win7 right click on your image burning program icon and slect "run as administrator."

Ok, I downloaded the 1.21 image, but it's still only running setup. It goes all the way through it, partitions, inflates files, removes install files, then shuts down. When I restart, it says "Loading" and goes right back into the same setup, penguin and all, but much shorter since the install files are no longer there. Everything was run as administrator when I created the boot disk.

This unit is a blue dot, and the only thing done prior was updating to BN 1.3.

Well, I played with button combos until I stumbled onto the recovery, wiped the device and reinstalled the os. It is now back to BN 1.2, so I tried to run the boot disk. Still no luck, it just re runs setup each time.

Sounds like there is a step you are missing somewhere. I think the image is 4G or larger for agnostic image.

Wipe card with SDFormatter to make sure it is cleaned. Then make sure you do each step in order.

The apps file will work just fine just do NOT unzip the two files you put on the card!!!

Now use this generic file because I did have a problem with the other one loading also so I used this one

http://myraroldan.com/wp/wp-content/...1.2.1.img_1.gz

use 7-zip and unzip this to it's own directory, then right click on the image file then paste it in explorer to the root directory

To do that I will assume you know how to right click on start and select explorer.

Navigate to directory that you unzipped file to, right click on it and select COPY

Then go to left pane navigate up to C:\ and highlight it then right click on it and paste.

Now close the window and open winimage and then browse to C:\ on left, then on right go all the way to bottom, and you should find
the generic-sdcard.img file, then click write

once done close win32image

Now copy gapps and update zip files DO NOT try to UNZIP, just copy the files to the card. use the stable one for Nook. eject card and place in nook color then boot.

Wait for the the Nook to go black, you can shut down and restart.

Hope this helps.

Well, I don't know what to say. I tried the new link, extracted the image with 7Zip, copied it to c:\, ran win32 image as admin to a freshly formatted SD card (SDFormatter), added the 2 UNZIPPED files, and still no luck. Is there any chance there's an issue with Win32image? I'm using release 0.2


Ran it again with 7.1, must have been a bad CM file, it's working now!
