Hi guys, new here.

I have an iPhone 3GS.

It was jailbroken, and unlocked.

I updated to IOS 5.1 by mistake the other day, and it removed cydia & the jailbreak etc., re-locking the whole thing.

So I downgraded down to IOS 4.1, where the jailbreak doesn't seem to be working.

Now I am currently trying to re-upgrade to 5.0.1, where there is an untethered jailbreak that works.

But I just can't.

I've tried everything, from restoring with the 5.0.1 .IPSW and even custom .IPSW.

Is there anything else I can do to get back to IOS 5.0.1?

My phone hasn't been receiving or sending signal/ data for the past two days...
