Hi everyone, My wife has a 3Gs running 3.1.2 it is an untethered jailbreak. This morning she turned it on and the apple logo came up then the phone shut off. It keeps doing this. The logo stays up for a shorter time than it normally does when booting properly. I got it in DFU mode and ran blackra1n and got geohots face to come up but it too only stayed up for a few seconds then the phone shut off. When I hit the power, all I got is the apple logo, then it shuts down again. Any thoughts?
