This is what's happened to my phone. I have it jailbroken and wanted to do a clean wipe. I tried to restore the phone via Itunes but then it came up with error 3192 or something like that. I looked on the internet and tried to fix that which didn't work. Don't know why…
Then i tried to do a restore within the phone directly from the settings function. Thats when the trouble hapens. It turns on apple symbol then jailbroken symbol then back to apple symbol then jailbroken symbol with circle turning. It does this all of the time until the battery runs out.
I can't put the phone into DFU mode at all.
I have looked on youtube and the net for answers but to no avail.
summarised restored jailbroken phone not through itunes now keeps trying to boot and doesn't work.
Please help I think i have properly bricked my phone.
