does this quickpwn work for windows i cant unzip the file

**bondkt** · 09-17-2009, 12:23 AM

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** · 09-17-2009, 12:49 AM

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

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** · 09-17-2009, 12:42 PM

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

**greaseball75** · 09-17-2009, 02:17 PM

I finally jailbroke my iPhone 3GS and restored it to 3.0, but now I have no service, can someone tell how to get my service back? Please help!!!!

Finally got my serice back and successfully downgraded from 3.1 to 3.0 on Iphone 3GS!!!!! Thanks a million, this is the easist way to get it to work!!!!!!!! You rock!!! Cydia, welcome back baby!!!!!

**zguy916** · 09-17-2009, 02:53 PM

Ok guys sorry to be a newbie bug ....lol Soooo after I get the second error code 1015 just close out iTunes and open purplera1n.exe and do a normal jailbreak ........once jailbreak completes open iTunes and it should activate my AT&T to work after the 3.1 downgrade and purplera1n jailbreak ?!? Thanks a lots guys

**bondkt** · 09-17-2009, 03:33 PM

or a lot simpler way is to do what i first posted, then use redsn0w to jailbreak =p

just so you guys know what the error is it occurs when the baseband you are installing is older than the one currently on the phone. the phone completes its OS installation first and THEN proceeds to the baseband. so quickpwn is simply forcing the phone out of recovery mode. thats all. just forces it to boot with what it has. then you see the initial springboard status loader which then makes everything better for the next boot. then just jailbreak as usual
