hey Lizards821. I'm using snowbreeze to update my iphone to ios 5.0.1. For some reason when I'm trying to update I get error 1602. I don't get any errors when I'm trying to downgrade from 4.3.3 to 4.3.X. so what can I do? I have shsh blobs, I use tinyumbrella with everything checked in the advance settings, use ireb, and before downgrading I edit my host file.

@Walgeo15 Restart your computer.

@ikathan26 I KNOW IT PISSES ME OFFF SOOOO MUCH lizards821 PLZ MAKE ONE SPECIFICALLY for IPAD 2

[lizards821]

@LikuidIze You can only downgrade the iPad 2 to 4.3.3 with SHSH blobs, which you shouldn't be getting any errors for.
