(How To) CM7 Bootable SD

[LostWish]

Hey, Great instructions I found them very easy to follow. However I have run into a giant problem. Everything seems to work fine, I put the card in it boots the linux I shut it off, I turn it back on and the internal books not the android. I have a nook color, not a tablet. And am getting extensivly frustrated about this. I have already restored it to factory once tried again and it still didn't work...

any thought?

Thanks!

you know... after reading everyones problems on this it almost sounds like the latest update is making it so you can no longer root your nook color. I may have to go take mine back and get a kindle fire if that the case. The only reason I got the color was so I could root it..

What problems did you run into? And what did you do to remedy said problems?
Thanks in advance.

I had a myriad of issues getting it to boot in Android. But what ultimately worked was to format my SD card with the Panasonic formatter 2.0. Then increase the partion to 150 with the eausus (sp?) Program. The use the imaging program (win32?) to image the SD card. Then copy the gapps and update zip files to the card. Finally insert card into nook and power on.

Short version:

1. Reformat to a perfectly clean card.
2. Increase partition
3. Follow steps on page 1
4. Bask in glory

THANKS for the instructions! A couple of quick notes from complete rooting noob (mentioned in the thread, but not on the updated instructions). If your Nook will not boot into CM7 (who knows why????), burn the image file and copy CM7 to your SD card FIRST. Turn on the Nook, let CM7 install. Make sure you have wifi, then turn off and take out SD card. Put into computer, THEN copy google apps file onto SD card. Put SD card into nook SD card slot, turn on. Once ON, hit the power button, this will give you the choice to reboot. Pick reboot then pick recovery mode. This will add google apps.​

It is best to update your Nook color to the 1.4.1 stock update and register your device prior to doing any modifications to the device.

This is driving me nuts! I've tried numerous times to make the boot disk. And it always shows 107 mb left on my card! What am I doing wrong?

When you make a boot disk that is all you are supposed to see. The rest of the card is formatted in a way that only the android OS will see. This is the correct result.

I'm sure its posted already but you need to resize the partition to get enough room for the other files to fit. Search here or read trough the threads to find which program you want to use to resize the partition. Hope this helpsa little.

Cool, now I understand. I'll continue with this tomorrow. Thanks for the help.

I followed the excellent instructions on the previous page but there is now a problem. When I boot, I get up to the blue android cyanogen (mod) 7 screen with a revolving arrow and no further. I have tried multiple times turning NC off and on but always get stuck at that step. What to do ?

How long did it stay there. It can take quite a long time to load for the first boot.

About 10-15 minutes. I will try to not look or poke and leave it for longer.

 

[J515OP]

Shouldn't be too much longer than that though. More than 20-25 there is surely an issue.

 

[Weebee]

Well, I'm rooted! FINALLY!!! Now I seem to have trouble loading the NC up with my books. I have it connected to my computer. It shows the two folder icons. One for the NC and one for removable card. I click on it and and tells me to insert media? Whats's up with that?

You have to boot into CM7 to connect and move things to CM7 internal memory and CM7 SD card memory. If you try and boot into regular Nook and then access the SD card it won't see it right (only the boot partition) since it is formatted for CM7 now.

Popular ways to move files into CM7 running on the SD card include dropbox and samba so you can do it wirelessly.
