Help Me In Downgrading Please!V3.0 to V2.2(2g)

[indianapple]

Hello There!
My 2g iphone was on V2.2 (already Jailbroken&Unlocked)
I used Redsn0w to upgrade V3.0.
Now i simply want to go back to V2.2 ...
Iphone 2G
Version :3.0 (7A341)
My Baseband shows: 04.05.04_G

Please guide me on to Downgrade
I also get the ERROR CODE 1600 in Itunes,when i try to Restore.
Please Help!!
Thank you

PS:I need to Downgrade ,because it seems the TV AV CABLE,Which was working Great in V2.2 is simply Not working in V3.0
I also did some search and found that There is NO TV AV CABLE is available&Apple has simply Kept aloof on saying whether their AV Component Cable for TV works in 2g Version3.0
Apple simply is not DEFINITIVE on saying that their Product works!Apple seems to be shy.
Thank you Folks for the Help i Will get from you.

i have similar problems...
I'm getting really frustrated here.
I am annoyed with myself as I had my 2G down at 1.1.4 with a spoofed IMEI and i foolishly upgraded it to FW3.01... now I can't get itunes 7.5 to see as I get the "this needs itunes 8.2" message. Also if i try downgrade to anything other than 3.0, then i get errors using itunes 8.2.

any ideas what i should do next?... I have on my phone now, v3.0 jailbroken, it says modem firmware is 04.05.04_G...... is this the issue?

i have tried everything on the forums but just need a bit of guidance.
thanks

Are you guys putting your phones into DFU mode before trying to load the 2.2 firmware? Not sure with the phone (I can't get my 2G to boot), but with the 2G ipod touch, DFU mode was required for going from 3.0 to 2.2.1

1st downgrade itunes to 8.2 the downgrade your ipod/iphone in dfu mode shift and left click on restore and click the firmware again and !!!GOODLUCK!!!!
