Issues downgrading iphone 4

For some dumb reason I decided to give os 6 a shot despite all the negative reviews. I was late to the party so I got ios 6.1 which is what i currently have. I thought I had saved the SHSH of 5.1.1 but I guess not. Sigh.. Atleast I have 5.0.1 which is what I plan on going to.

I've tried every method with no luck. I initially tried using redsnow, but upon the software working its magic and telling my iphone to reboot it would fail as I'd get a "couldn't find recovery mode device" message. It is odd because once i plug my iphone in, it takes like 5 seconds for it to be recognized.

I then built several custom 5.0.1 GSM firmwares(I have an ATT phone) using my shsh. I ran the TU TSS server, put the iphone in DFU mode, and I cant ever get itunes to install the custom signed firmwares. I tried it with the 'request shsh from cydia' option both on and off in TU. I tried all the different built firmwares. If I run TU i usually get a 1646 or 1645 error which i have notreally been able to find fixes for.

By the way, when I say DFU mode assume pwnd DFU. I've used both redsnow and ireb to put it in the DFU mode and neither of them gave me a different result.

The things that stick out to me is that from the DFU mode things begin just fine, but then the iphone restarts, and I guess it's supposed go into the firmware update screen with the loading bar. Just something I recall from previous experiences of jail breaking, upgrading, etc. The iphone simply goes to the home page, with nothing exciting happening. After an unsually long time it will then get picked up by the computer. If I use redsn0w I will get the error while the apple loading screen is still up, just moments before the home screen shows up. When I try the itunes approach it just keeps saying 'prepairing iphone...' until the phone is picked up by the computer, at which point I usually get some kind of error message. Honestly I've gotten many different ones. But as of late the 1646/1645 are the persistent one. The other thing is that the iphone takes an unsually long amount of time getting picked up by the computer after a reboot from the DFU mode. If I were to just plug it in during normal use, it would get picked up in maybe 1/2 or even 1/3 of the time.

Anyways imopen to any inputs and I'd appriciate it!
