Hi, I am brand new to the scene and as a resuly have been googling like crazy but I'm keep getting conflicting information. I bought a Iphone 3g JB/UL on os4, but it ran too slowly so I wanted to downgrade. I did a right-click restore from itunes to a 3.1.2 firmware. I got the 1015 error when it was done and used RecBoot to kick it out of recovery mode. When I turn it on, I expected to lose my unlock and jailbreak, but I'm stuck at a "connect to itunes/emergency calls only mode" I tried to run redsn0w 0.9.5b5-5 to hacktivate it, but when I direct redsn0w to my 3.1.2 firmware it gives me an error that says "unable to recognize specified ipsw" am I overlooking something simple? will I need to find an AT&T sim to move forward? I would truly appreciate any help thanks ------------------double post merged------------------of course, 5 minutes after I finished my post I came across some useful information. I tried using redsn0w 0.9.4, and it accepted my ipsw file and let me in. In case anyone else was having a similar problem, that is what worked for me.
