i want to downgrade back to firmware 3.0 but i cant seem to find a solution with ireb any help please?
 
i could never unlock it as my bootloader upgraded to 6.02 and ultrasnow 9.3 could not do it either with my 5.12 baseband i just managed to jailbreak with spirit. so im downgrading to 3.0 but im stuck since ireb only supports up to firmware 3.1.2
 
my iphone is 3gs 3.1.3 BB 5.12.1 bootloader 6.0.4 an it has been jailbroken with spirit and unlocked with ultrasnow

you try to unlock with wifi or??
 
yes u tried to unlock with ultrasn0w through cydia yes with wifi on, does it have to be turned off??
 
well i dont get errors it just never unlocks the sim card its weird because i use an original att sim card and it still shows "no service" all the time.

i just install blacksn0w from the 666repo in cydia but with no errors...
 
Are you sure the SIM card is working? Have you tried it in another phone? Usually prepaid SIM cards expire if not used for some months.
 
you could be right there i will do that and post back when i try a working sim card.
 
omg!! i must be the stupidiest person lol yeah it turned out my problem was my deactivated sim card no wonder it never gave me signals once i put my working mexican telcel sim card it quickly worked thanks https and kings121
