Without blobs, you can't restore to an iOS that's no longer being signed unless its iOS 4.1 on the 3G and 3GS. That's basically the universal law. Then you have downgrading restrictions like the the 4S and 5 where you can't downgrade without taking advantage of something.

As stated above... there's no way to downgrade the 4S or 5 on iOS 6.0+. My question is... what "error" are you refering too?ahh drain my battery fast and I have this error as well
Quite hazardous indeed...I'd take a hazardous guess that the error is that the battery usage isn't displaying.
Can the new version 6.1.2 be jail broken? I'm due for a replacement iPhone 5 next week off apple I mite get it fixed my self if not. Thanks
Yes, iOS 6.1.2's JB is untethered.
