Alright, before you reply going "OMG YOU CAN'T DO IT WITHOUT SHSH BLOBS", just "hear" me out. I've done a tethered jail break on my iPhone shortly before iOS 5 was released. I never had to download TinyUmbrella or need any SHSHs. I reverted to normal because I was very annoyed with tethered. Now, I decided I wanted to jail break again but do untethered. I have run into many problems. One is the requirement for SHSH blobs. I didn't even know they existed until now (I also figured they were some form of verification hash which I ended up being correct about). So I then proceeded to Google if there's a workaround. I have seen a few tutorials claiming you can without SHSHs but have proven unsuccessful. I have gotten Error 20 and Error 3194 from iTunes in the process. Here were the sites I was talking about (claiming no SHSH required). http://gdeluxe.com/downgrade-ios-5-0-to-4-3-3-without-shsh-blobs-saved/ (quite poorly written IMO. Very unclear in many areas). http://www.limera1n.cc/2011/08/downgrade-435-to-433-without-shsh-blobs.html So, from any of you here, is it possible to downgrade without SHSH blobs? Or am I screwed?
