    Take a look here. Its a simple process. However you cannot downgrade or load iOS 8.1 now. Apple is no longer signing. So not sure why you need DFU as opposed to just a restore but you can download 8.1.1 ispw file and and use it still for now (probably til tomorrow if I were to guess). But not 8.1.
