Iphone 4 IOS 6.1.3 BB04.12.05 Downgrading problem
Hi, i got a iPhone 4 16gb running IOS 6.1.3 running tethered jailbreak, baseband 04.12.05.
locked to UK 3 hutchinson Network....(i paid for a carrier check and got this info through my IMEI)
i tried to get shsh blobs from tiny umbrella and it says there are only blobs for 6.1.3, i also tried iFaith and samething, its not on remote cydia server also...
i want to downgrade to firmware 5 or 6.1.3, so i can jailbreak untether and try to reduce the baseband so that ultrasnow can work. or even use a gevey or Rsim.
i cannot downgrade or restore firmware through itunes, first some 3149 error came i use tiny umbrella TTs server and no more 3149 error, but now 1600 error shows up after extracting ipsw on itunes.
Please help, and give me some steps i can do to get it atleast to use a untethered jailbreak,(evasion)

You can't downgrade the baseband on iPhone 4 just update to the latest one. As for as downgrading to a lower firmware if ya don't have the shsh blobs. That can't be done either
