Hello all, I'm new to the forums & new to iphone world. Device: iphone 3GS. Firmware: 4.2.1 Problem: Done reset content/data- now stuck in recovery screen with itune logo & usb cable' 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 tried tiny-umbrella to get out of recovery mode. But as I said there's no saved records either. Also tiny umbrella could not recognise device serial no. or name. I know it's jailbreak so... yeah shoot me. but is the any workaround? How can I restore or install and make it functional? Would downloading ipsw/firmware files from apple help? I dont mind wiping /formating all data as there's nothing mine saved. wanna make a fresh start. Also I dont mind getting out of jailbreak version.. In fact it would be great if I could cleanse iphone & come out clean. Please help me out! I read lot of similar discussions here. Thank you.
