Root [Guide] How to make a bootable CWM (ClockWorkMod) or TWRP bootable sd card (06-04-2013)

Actually this is a Windows guide. You can use dd to write the files to your sdcard. This guide might help with the "dd" command. I'd be happy to update all my guides to Mac friendly if someone can tell me what's needed.

It's pretty hard to brick your NC using this guide. Worst you can do is create a sdcard that won't boot. :D
 
I updated the original post to 3.2.0.1 versions, eliminating the extra steps of updating individual files from a downloaded zip. Let me know if you have any issues.

I'll add the TWRP images soon. :D
 
This seems to be working great. I am using a 2Gb card to do the boot and backup. The backup has been going now for over an hour. How long does it normally take?
 
ok I did everything in post 1, put sd card into nook, powered on, now it has the skull/crossbones and says loading. It has been stuck on this for 10 mins. help please
 
Time to start over. Skull and cross bones is ok, but something else isn't working.

What image did you use (size) and was it CWM or TWRP? I just updated this today so it's possible there's a problem with the image. The 3.2.0.8 image WILL work, but needs to be updated to 3.2.0.1 (post 3)
 
Which TWRP file do I download? When I click the link for the 4gb TWRP there are alot of different downloads, which one do I choose?
The first one I downloaded wouldn't extract, just kept saying error.

How could I tell? The file names are changing, albeit slowly. Maybe I'll kill it an throw in a 16gb card for just the backup.

Is this a new sdcard?

What brand/speed is it?

If they're changing, it sounds like it's still working but it sounds like a goofy/defective/failing card.

You can boot off this card, then swap cards, then create your backup.
 
magaupload was down when i tried to download the 4gb bootable cwm 3.2.0.1 sd card image ... can u please tell me where else i can find that ? thank you.
 
 
Any chance you have the stock 1.3 software? That isn't available either and my girlfriend's nook is currently a BRICK. :(
 
I have it, but it's going to take awhile and not sure if it resumes if interrupted.

You can do wonders with a bootable sdcard and wiping data, & caches. :D

You also have the 8 failed boots you can try if it's the stock rom.
 
I got my Nook Color (16GB) yesterday. The software version is 1.4.1.

I followed steps in post 1 to created a CWMR SD card and here's what I did:

1. Downloaded 2GB bootable cwm 3.2.0.1 SD card image;
2. Wrote the image to a 2GB Kingston MicroSD card with Win32DiskImage. I waited until the progress bar reached all the way to 100% and "Done" showed up at lower left corner.
3. Ejected SD card from PC, power off NC, insert SD card, power on, and my Nook booted right into the stock rom but not the CWM recovery menu.

Help please.

P.S. There are four files in the flashed SD card :
mlo
u-boot.bin
uImage
uRamdisk

The used space is only 4.5MB. This is weird since the image itself is about 1.8GB.

Sure. The bootable card still works. What you do with it may change tho. :D

What's your intent, installing a custom rom like CM7 or rooting?

If it has 16GB, you probably have a Nook Tablet,not a Nook Color. They look VERY similar, but are completely different pieces.
