3GS on firm ware 3.1.2 stuck in DFU Mode black screen please help!
Have similar prop execpt not on version 3.1.3 I Got a brand new 3.1.2/5.11.07 3GS the iPhone Dev Team blog states that Pwnage Tool is safe for 3.1.2/5.11.07 - so I went that route to get 3.1.2 back to stock.
Long story short - error 1600, stuck in DFU mode. Not amount of holding power, or power+home gets me out of if. My only option is a restore to 3.1.3, so I have a rather expensive paperweight until a 3.1.3 fix is put out but i have not done it yet any help would be much appreciated thanks in advance
