Won't Jailbreak? Stuck on white screen?

I'm attempting to jailbreak my iphone 3G on a Mac but am having no luck. When I get to the part when the phone goes into DFU mode my screen turns white and remains that way. The quickpwn app continues on as if there is no problem all the way through. The screen remains white for apprx. 10 minutes then shuts off. And my phone is back to normal after powering it on but not jailbroken.
I've read of other people having this problem in other forums but I haven't found a solution. Can anyone help?

if your mac is updated to OS X 10.5.6 the problem you are running into is that the mac will not recognize it in DFU mode and therefore cannot be rebooted in its jailbroken state. there is a fix for this somewhere on here, but if you have another computer to jailbreak with i would recommend doing that for the time being.

No I'm running 10.4.11 and my itunes and iphone are proper firmwares as well. My wife has a mac at work I may have to use.

ok we can figure this out, your screen turns white on what, your iphone or your computer? i would recommend uninstalling quickpwn and redownloading quickpwn from this link:

and redownload your firmware file from this link:

then try to rejailbreak. do this and let me know if it works.

My iphone screen turns white and remains that way. I've tried your suggestions and unfortunately no luck:frown: I have read online that other people are having this problem I just can't find a solution.

I have now tried to Jailbreak on a different Mac where my wife works and I am still getting the same problem! If anyone can help it would be greatly appreciated.

i had this problem on my macbookpro and a couple of other macs, tried it on a windows pc and it worked first time. it sucks though cause i much prefer mac!

When jailbreaking on a PC does it have to have iTunes and does my phone have to be synced with the PC or can I simply plug my iphone in download quickpwn and jailbreak?

the machine i used did not have itunes, goodluck!

i have a white iphone 3g 16 gb but i tried to jailbreak it and once it finished and it said done then it went to a white screen and i had to restore the whoooole phone. can u help me here please??
i used quickpwn to jailbreak it.

I wish I could but mine still isn't working. I'm gonna try and jailbreak it on a PC tomorrow at work. I have to be careful I don't get caught!

Finally success! The PC worked, I'm jailbroken! Anything I should be cautious about going forward?

Thanks everyone for all of your help!

iPhone white screen

When you guys took your iPhones to the store do they check warranties or serial numbers? I am gonna buy mine from ebay and I wanna take it in instead of paying 3x the amount it cost to buy the phone

Try this:

Set your phone to DFU-mode and then connect it to your computer. Open iTunes and restore. Now try to jailbreak it again.

I had some problems myself with jailbreaking a couple days ago (upgraded to 2.2.1), so i set i to DFU-mode and restored it again and it worked.

Not sure this will work, but it's worth a try i guess.
