Want to root but don't have a microsd card reader? Is the 8 failed boot trick leaving you tired and bloated? Have you had nightmares of Winimage drinking all your beer and stealing your car?

Help is on the way.

This pile of utilities, images, and scripts will boot your Nook into CWM recovery entirely over USB. Your eMMC can be trashed and SD card missing, but you can still get into recovery. This is kinda rough, and Linux only for now, but a Windows version is in the works.

Need:
-PC running Linux (x86 or x86-64 with 32 bit compatibility libs)
-Nook Color plugged in w/ USB
-this archive unpacked: nc-usb-recovery-0.1.tar.bz2

Do:
-turn off NC
-sudo ./booty
-turn on NC
-wait

Awesome work!

I would love to make something like unrEVOed's GUI for simple rooting/cm7 installations.

Does this just grab a kernel + ramdisk from usb? Any chance of any larger storage? (or use adb + /media?)

It doesn't really matter what you send since after the kernel gets booted it doesn't matter how it and the initrd got loaded into memory. Ultimately we're running almost the same u-boot as we do off of mmc media and booting using almost the same boot scripts.

In this case, I'm sending CWM as my payload. CWM lets you share out /sdcard over usb, which isn't the most convenient way to make a "one click" solution. You could pretty easily hack up CWM to look to the initrd for one or more update files. Or like you said, use adb. You could even replace the kernel/ramdisk payload with one of the *nooters for a simple stock root.

Any chance of this getting updated to a newer cwm/twrp version?

Any ideas?
Not much has been added to this thread lately, but I am hoping someone may have some ideas about my problem with this method. Pasted below is as far as I get and it hangs at < waiting for device >:

waiting for OMAP3/OMAP4 device...
sending get asic id message to target...

The error seems to be "unexpected 2ndstage response". A few things about my Nook; first tried it registered and than I did the reset.., same thing. Version 1.4.2. Thanks ahead of time for any assistance!

You have to have it off and plugged in and then hit power about 3 seconds after it says "waiting for device." I also have never tried it with the stock boot loader so that might be the problem.

Thanks for the input, will try that later on. When you say stock boot loader, you mean from the factory as is? It was my impression this was intended to avoid using a SD to root. Is there something else that I need to do before this method?
