The Instructions

omg omg really simple here we go here we go:

2. download this old quickpwn file:

http://www.mediafire.com/file/3zzmt5znnkm/QuickPwn.zip

3. extract it and run quickpwn. You should get a box saying something like 'your phone needs to be powered on, please hold the home button and sleep\wake button for 15 seconds'. Just do what it says- EXACTLY. When you see the apple logo, press OK. A blue box will appear after, just press OK to that as well.

4. Your phone should now boot normally. when it does,CLOSE QUICKPWN, IT IS NOT USED TO JAILBREAK.

5. Use redsn0w 0.8 to jailbreak!

NOTE: If you ever want to downgrade to 3.0 again (say a another restore or something) you'll have to follow these instructions AGAIN.

Your set! huzzah!

does this quickpwn work for windows i cant unzip the file

[bondkt]

Yes it does, you just need a better unzipped, go HERE.

download the 32 or 64 bit (whichever you have) and try again, should work =)

if not post again and I'll send it one unzipped.

nice....i ran into this error.

they say 2G and 3G is safe to restore back to 3.0 or 3.0.1 but its not the case. restoration will finish half way but with an error. but i believe it is fully restored...but not verified through itunes.

[bondkt]

It is (you don't To edit the host file). Bit if you downgrade from 3.1 to 3.0 on any phone you will get error 1015, and this will fix it, no matter if your a 2g, 3g or 3g[s].

Hi bondkt, I've followed your instructions, but when I browse for the IPSW file and click on it, it says it doesn't recognise it?!? I've downloaded 3.0 & 3.1 IPSW file and it won't open any of them. Any advice or pointers?

Thanks in advance

i'm not downgrading...i am simply restoring to 3.0.1. my 3g came with 3.0 so i'm restoring to 3.0.1 and jailbreaking it. but it doesn't finish restoring. it gets half way on my phone then error. then my phone is stuck in DFU mode. so i use quickpwn to get it out of it.

so i end up with the "slide for emergency" screen. i'm guessing its back to the fresh restore...so i jailbreak it with redsn0w.

is this similar to your problem?

Ello! Are you meaning in itunes or quickpwn?

If your meaning itunes: try uninstalling then re-installing, and re-downloading 3.0 FW again.

Quickpwn: after you phone boots to the lock screen, you don't need quickpwn (it wont jailbreak your phone).

To jailbreak it, download redsn0w 0.8 from the dev-team here:

Ah i gotcha. Saurik saved 3.0, not 3.0.1. So if you have your ECID on file with Saurik, it'll restore to 3.0, not 3.0.1.

I also tried to restore to 3.0.1 but it failed. Did 3.0 and worked fine, try 3.0. If you you didn't upgrade to 3.1, you shouldn't even get an error message =P

[krascal2323]

After the second restore do not USE red snów , use purple rain. Purple rain will roboot your phone without using irecover or quickpwn. after jailbreak is complete youll be stuck in recovery modę simply disconnect open iTunes and reconnect. iTunes should rocognize your device and activate your service with atnt.

[bondkt]

This method is a lot simpler, and gives you the opition if you wan to jailbreak or not ( most do though ).
