Hello all, I'm new to the forums & new to iphone world. Device: iphone 3GS. Firmware: 4.2.1 Problem: Reset data- now stuck in recovery screen with itune logo & usb calbe' I bought used iphone & thought to reset all data & upgrade the software. Since I want to make a fresh start & dont want previous owners records I reset it. Once I reset all content & data, I was stuck in blank screen with apple logo (& danger/ghost-skeloton-like logo) It appears that its a jailbroken iphone. After reading loads of stuff online (& MacRumors forums of course) I could bring it in recovery mode. & now in itunes I only can see summary tab & name & firmware details all wipe-out. except serial no. Still in recovery mode: itunes suggested to restore & upgrade (which is what I want to do) but it failed to restore, I sometimes get error 1055 or 3194. I know it's jailbreak so... yeah shoot me. but is the any workaround? How can I restore or install and make it functional? I dont mind wiping /formating all data or apps if there any. Pleeeeeeeeeeeeeeeeessssssssssssse help me out here. I read lot of similar discussions here. Thank you.
