[CyBorg82]

hey I am new to this

I have an Iphone with FW 1.1.4 jailbroked, Unlock and Activate.
Then I wanted to upgrade to FW 2.0.1, With Winpwn 2.0.4 and installer 4, BUT that didn't turn out so well, I got an Error 6, that i removed using a new Custom FW with Cydia
my iphone starting up it then begins to Flash the Bootloader and then it Crashes now i got an error 1604.
I attempted to recreate it using Itunes restore. But I STILL recieve the Error 1604

I've tried Recovery Mode and (DFU-mode Black Screen) But I still recieve the Error 1604
Every time I've run a Restore, I get an Error 1604, My Phone get's the Apple Logo it remains there with a wheel at the bottom for hours.

i try to partition sizer 500 - 1000
i try to reinstall iTunes 7.7.1
i try reinstall Winpwn 2.0.4 - 2.0.3 - 2.0.2
i try other computers XP, Vista

Now I get the Error (1604) every thing I try, what do I do?

Make sure after you create the custom .ipsw, you pawn Itunes (iPwner button), if you dont you will get that error.

make sure you are in DFU mode and not connect to itunes screen.

Ok i jailbroke my 3G on the first try with winpwn 2.0.0.4. i followed the bigboss tutorial, i would post link but cant find it. this is what i did different then the time i tried about a week ago and got the error from itunes.
when i clicked on IPSW Builder and clicked on the propper firmware. the IPSW builder window poppep up.
on APPLICATIONS i checked Cydia, and Installer 2.0. on CUSTOM IMAGES you check what you want. on CUSTOM PAYLOAD i left it unchecked and did nothing to that.
on ADVANCED i unchecked Activate Phone and left everything Unchecked (if you are activated with AT&T then you have to leave everything unchecked)
now on PARTITION RESIZER i set it to 550MB..
then i clicked on Build .ipsw--
after it finished building it i clicked on iPwner and iTunes shut off then you get a message saying pwn successful.. or something like that. then i Set my phone on DFU mode.
pressed Shift+Restore and clicked on the propper CUSTOM FIRMWARE that i just made.
and i let iTunes do its thing.
came back about 20 minutes and BAMN!!!!!!!! 3G pwned.

Hope this helps. and good luck!!
