Thank you but your link seems to be wrong..give me the right one pls

So far I tried
Downgrading itunes to 7.4.3.1
Using downloaded 1.1.2 firmware instead of online update
Unistalled firewall in my laptop
Updated Java

only to get the same result.
What more can I try? any idea pls..

It just stops at this point..
So if I click cancel after a while..then the black Dos screen shows following screen..



any input pls?

Download the jailbreak again, just to be sure you don't have a damaged .jar file.

Also, are you running the latest java runtime environment (JRE) ?

You're getting a null-point-exception but you SHOULDN'T as the program works flawlessly, probably a java issue or incompatibility with your environemnt.

Try it on another machine, with another java, and it must work

(If I were you I would install a clean windows on another machine (english one), a clean itunes 7.4.x, and a clean JRE (latest one). That SURELY would fix your problem Forget itunes 7.5.x.

duwde

thanks, but I already downloaded jailbreak.jar about 10 times..
and also updated java several times..I think I should try this on someone's Mac..

2 hints for you:

1. Mine succeed jailbreaked and activated with tutorial of: http://iphone4.tw/blog/2007/11/29/165/, the screenshots may helpful to you.

2. Similiar problems were reported with non-ASCII directory where tools resides in. I notice you are using Korean OS with Korean Login name. So just create a pure ASCII login name with admin rights, and place all the tools in pure ASCII directory name, like c:\iphack.

Try it and it may help you out of your problem.

I changed my Korean login ID and directory names....and it worked!! after 3 days of failure!

And many thanks to others,too.
