This is just another post that builds up hopes but doesn't actually work as the title suggest.
The original post presumes SHSH is already saved and you're on 4.1 firmware then tells you to upgrade before you downgrade. Complete rubbish.

There's some posters on here who don't help anybody at all and if I wasn't so cynical, I'd probably suggest Apple personnel have infiltrated the forum. If you believe this will actually work and go ahead and try it, you may very well end up being forced to update to the latest firmware because it's the only one that Apple are signing.

Follow this at your peril.

mr underdog as you can see in this thread many people succeeded, then why you always try to get an error from every body ? this is a forum for the people who want to learn n teach. this forum is not for the people whom just laughing always on other.... and you man never say thank any one even once so take your overconfidence with you mr underdog:eek:

not work dear and other link

which link is not working? and what do you want to do?

Hmmm Looks good but its a mistake by Apple servers..These servers still signing old 4.1 firmware so we can still restore to this version...I did too many phones without the need of tinyumbrela or green poison...Just put phone in special dfu mode with redsnow and after that just restore with 4.1 custom firmware!...Enjoy!

yes you can, first clean you hosts file (leave as normal) then connect to tinyumberellah and save shsh then you will see in the list select 4.2.1 and do according to my first post.

But if you don’t have any backup saved then no problem at least you can downgrade from 4.3.1 4.3 to 4.1 old boot or new, no problem just follow up the step by step guide.

100% DISAGREE . . .
