If you're here, I'm assuming you've bootstrapped before, installed a custom rom, etc, and now wish to return to stock motoblur and remove bootstrap, whether it be for an update, or another reason.
I will also assume you have a capable root explorer app, such as the aptly named Root Explorer, or one of several alternatives, such as File Expert (this is a root explorer! Just check its settings). I am using Root Explorer for this de-bootstrapping.
To begin, open Root Explorer and immediately hit the "Mount as R/W" button whenever you see it-it is imperative that you do, or else it won't work properly.
Immediately, whether under the immediate view or "/system/", scroll down to the preinstall folder.
Inside there will be a folder named Recovery, with 4 files, 1 of which is important to us: Hijack. You may delete it OR move it to your sd card.
Second, open the /system/ directory, scroll down to bin. Open it.
Again, R/W button as needed.
Scroll down until you see a file named Hijack (yes, there's two of them). Delete or move it.
Scroll down again until you see two files:
Either move or delete the first logwrapper.
Then, rename the logwrapper.bin to logwrapper
Reboot, battery pull a couple times, and if the bootstrap app is still around, hit reboot recovery a few times. If android boots up normally without clockwork popping up when you hit reboot recovery from the bootstrap app, you're all done!
Note: I notice there is a logwrapper present in the system/preinstall/recovery folder. DO NOT DELETE THIS.
I AM NOT RESPONSIBLE FOR WHAT HAPPENS TO YOUR PHONE WHILE FOLLOWING THESE INSTRUCTIONS! THESE ARE WHAT DEBOOTSTRAPPED MY D2G.
