[Resolved] iPhone 3G 3.1.3/6.15 - Can't downgrade baseband

PsstGreek · 05:00 PM

A friend of mine gave me is iPhone 3G which was stuck on the Apple logo. So I restored it to 4.2.1, lo and behold I got an error 1015. It has the iPad baseband I know of on it. How would I get this thing into Pwned DFU mode so I can use the custom firmware I made. When I try redsn0w stops the countdown because the phone is in recovery mode.

You need to persevere with DFU mode. Ignore the recovery mode logo on the phone (the USB cable) and hold the buttons down as instructed. It *will* go into DFU mode.

I got it. Downgraded it to 3.1.3 then used Tinyumbrella to kick it out of recovery.

Now I'm getting a "usb connection problem"

Alrighty, I have this phone on 3.1.3 with the iPad baseband. Now for some reason this one doesn't seem to want to downgrade or do anything.

I did another 3G, I have, same circumstances and it worked perfect. Right now, I'm just baffled. Any help would be nice.

Sometimes it takes more than 1 try

I've tried almost a dozen times, even on a Windows machine. Still no joy.

Finally, I got. Downloaded PwnageTool 4.2, created a new custom firmware, restored to 4.2.1 and downgraded the baseband. Bought an unlock from unlock_fusion
