4.1 to 3.1.3 on 3g stuck on pineapple

[BarcaMagic]

Well hello everyone, its been a while since last time i posted and i need some help. I have a 3g i upgraded to 4.1 since i didint need it , spare phone. Its baseband which couldnt be unlocked on 4.1 and now i need to unlock it. So what i did is downgraded to 3.1.3 jailbroke and everytime i go into cydia to install blacks0w it installs and it says 'enjoy your unlocked iphone' and when cydia reloads my iphone freezes. It gets stuck on pineapple/apple logo and well thats it.
If anyone could offer any help, advice i would appreciate it.

You cannot downgrade your baseband so cannot unlock again until a new unlock comes out (which should be sometime this month). Your one hope would be to restore and jailbreak again and search for fuzzyband in cydia and see if it tells you whether or not you have a iPhone 3G that can have its baseband downgraded, however they are very rare.

You might as well restore to your preferred firmware and do the jailbreak to use it as an Ipod touch for now. No tools will unlock your baseband.

Thank you guys for advices. I think ill just leave it alone for now. Its a spare phone i was just bored and decided to mess with it.
Thanks again.

It's worth checking for fuzzyband as x98car suggests. But you might as well go back to 4.1 first and try it from there. Jailbreak it with limerain and then search for fuzzyband in cydia.

I helped someone this week who was lucky enough for fuzzyband to work for them and it worked a treat. You might be lucky.

Limera1n doesn't work on iPhone 3G, he would have to use redsn0w.

Sure,not thinking.
