Just follow the steps in the guide and you should be able to downgrade and be jailbroken at the same time. The was a user that posted that you need to point redsnow to 4.2.6 instead of 4.2.8...
 
Unless I'm reading it wrong, that doesn't help you downgrade your phone, just fixes the recovery loop afterwords. iTunes won't downgrade, just gives the error when it tries to verify with apple.

I've included my hosts file just in case theres a problem there. I can't think of what else could be going wrong.

I've made the guide as simple as I can. If your still struggling create a thread explaining the part(s) your having difficulty with...

Did you save the SHSH's for the device your trying to downgrade? Did you save via tunyumbrella or cydia? What firmware are you on and what firmware are you trying to downgrade to...?
 
Nope in purchased the phone 2nd hand and it already had 4.2.10 on it so I'm just SOL.
 
Hi have a replacement device that has 4.3.3

How can I 'save' this just incase I upgrade?
 
Since apple use no longer signing 4.3.3 SHSH's you can only use iFaith (windows only) to save them...

Thanks. My iPhone has been configured to a Mac. Does it matter if I use iFaith on a pc?
 
The Iphone ios 8.4 is unstable, I would go for the downgrading. thank you
iOS 8.4 cannot be downgraded as no earlier iOS version is still being signed.

Also, this thread is almost 4 years old and the original participants are no longer active.

With that, this thread is now closed.
