Need Help Unrooting

1. It's a warranty issue, so please don't ask why I need to unroot.
2. Yes, I've search.

My phone (a Motorola Droid) is rooted: 2.1 Bugless Beast V1.1 running at 1.2GHz.

All the files I need are on my computer at work, at least I hope so. That said, I'm at home, won't return to work until Monday and this is somewhat of an emergency. I'm looking for the unroot.zip file. I've search just about everywhere. All the links I've tried are dead, expired, or simply not working. Any assistance you can provide would be greatly appreciated. Thanks in advance.

Edit: Found the file. Mod please delete.

 

Just look for the sbf file for 2.0.1 that will unroot you. Also, I think there is a 2.1 sbf file somewhere on the forums.

 

use my guide and just stop before the rooting step you may want to backup your apps and data before but since it sounds like you will be returning it you may not need to

Use the following link to unroot. I have used it when I had to turn my husbands phone into Verizon because it was not working. Verizon went through his phone trying to "fix" the problem before they would issue a refurbished and they did not see any indications of rooting. hehehehe
