Does Dev Mode void my warranty?

uh does having stickers on my xbox void with my warranty please help?

Sometimes contacting the main customer service line and asking them can net some results. Depending on how the work order was made, whether through them or on your own, they can often see the work order notes. Depending on what's wrong though it may not
go all that in depth. It's enough to just have one of the seals be tampered with to void the warranty or if it shows significant signs of wear or abuse externally. But I'd start with giving customer service a call, 1-800-4-MY-XBOX.

Hi

You will need to contact the service center and request details on why the warranty was voided.

So does this mean only my associated account can use a dev mode or can I use one of my other Xbox profiles to use dev mode?

Actually, You ever heard of the Magnuson-Moss Warranty Act? Simply breaking the sticker does not void the warranty, you would have to cause damage to the xbox's hardware to void the warranty. The act also covers the use of an aftermarket hard drive. And
as for the proprietary encryption on that hard drive is covered by the Sherman Antitrust Act. So basically Microsoft cannot ban you or void your warranty for taking the 360 apart or for using aftermarket equipment. Hope this helps people.
