iPhone4 iOS 5.1 downgrade

[D0MI.]

I, i have an iPhone 4 iOS 5.1 and I jailbreaked thetered and restarting with redsn0w sucks, so i tried to downgrade to 5.0.1 or 4.3.3 with Sn0wbreeze, Redsn0w, Tiny Umberella and iPhone restore, but After extracting iOS Software iTunes just gives out Error Codes( 2005, 11, 3194, etc) Now I restored without Pressing Shift normally to 5.1, but I can't downgrade!
Help!!!

Ok After i did all this He returned an Error, but then I selected a downloaded 5.0.1 IPSW and He createt a New signed Version with the Blobs. Now i just opened iTunes and did Shift + Restore and selected the signed. Now i have an iOS 5.0.1 iPhone 4 downgraded from 5.1 :P and Sorry for my Bad english i'm German.

Ok to Save the SHSH Blobs I opened Tiny Umberella As Admin, Next Plugin your Device or better do that before. Now tap on "Advanced" and Select a Folder Euere you want to Save your Blobs. After that tap on your Device in the Top Left Hand Corner and tap on Save Blobs in the Top right Corner. That's it. I saved them on 5.1 and He created 2 Blobs 1 in whitch's Name is 5.1 and 1 with 5.0.1 in the Name xD

Ok it didn't really work. Remember: I used the Blobs from my iPhone 4 v5.1, so now I can't Jailbreak. I Need the Blobs of an iPhone 4 v5.0.1! Can someone give me His to Download?

No can do.

They need to be from your device, as they're tied into your UDID.
