ERROR 2005 when downgrading from ios 5!! Any solutions??

[Dogg77]

I wanted to downgrade one of my iphones from ios 5 to 4.3.3, just for the untethered jailbreak solution.

itunes 10.5, unpacking files for firmware etc, after the server check, the error 2005 comes up.
Looking for answers on the internet, gave me: Change USB cabel or port..
Well that didnt work out...

Anyone having this problem??? Or a solution would be awesome !!

Downgrade iTunes to anything other than 10.5.

As Labman said. Without blobs you can't downgrade to 4.3.3. The only way you can do is to install the latest firmware Apple is currently signing.

I didn't have to downgrade my iTunes in order to go from iOS5 to 4.3.3 on my ip4 .

Okay, tried again, deleted all apple applications on my pc, bonjour-apple mobile device helper-quicktime-itunes.
Then installed itunes 10.4.1 again fresh, restarted, back again:
Runned iReb DFU because of errors, then tinyumbrella, then shift-restore itunes.
Restore was working until it stopped at 75%, then I tried several fixrecovery apps, including redsn0ws new one included in redsn0w. But nothing worked well, it turns on, black screen, shows a lot of white letters and turns off again after.

The only thing that could manage to boot up was the "tethered-boot" from redsn0w, voila on 4.3.3! BUT Now it goes into DFU everytime i turn it off, and have to boot tethered! Now what should I do?

I had to... Wouldn't work w/ being pawned DFU and on iTunes 10.5. But worked fine on 10.4.

I've read people on Windows are having to downgrade iTunes to downgrade to 4.3.3. So who cared what you have to do as long as it works huh

If that the case,then it is something wrong then. 4.3.3 suppose to have untethered jailbreak.
