Hello, I have a question. Before I put my device into DFU mode, I saved SHSH blobs on Tinyumbrella. It is not getting out of DFU mode, so I was thinking, how to I just restore to a SHSH file I saved in TinyUmbrella? And if I don't have to, how do I get out of DFU mode? I tried the button method but it doesn't work. 
I really want my iPhone to work, and I want to get it out of DFU mode.
How do I know which one is for the 4.2.1 one? I have 4.2.1 but I tried to upgrade to 4.3.3 but failed with stupid errors and I'm tired of experimenting so can you please provide a quick how to, or an article or something? Thanks
