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

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.

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?
