Hi, I'm not sure this is the right section but anyways, I've updated my iPhone 3GS to 5.1.1 baseband 6.15 using a custom ipsw made with ultrasn0w. So I am now stuck with a DFU loop, my iPhone won't come out of dfu doesn't matter what I do, Restoring in iTunes gives me error 28. After some research I found out that the only solution for this error is to open my iPhone and remove the battery or let the battery drain So I have two questions; Is there a way to drain my battery fast? Is it possible to see my iPhone's battery percentage on my PC since it's stuck in DFU? Thanks a lot!
