This guide is for how to upgrade a 1.1.4 or previous 1st generation EDGE iPhone NOT 3G to the iPhone 2.0 firmware using PwnageTool 2.0.1 by the iPhone Dev Team.
Required Downloads:
Make sure you are using the latest iTunes and connect your 1.1.4 1st gen iPhone to iTunes. You should get a pop-up asking if you’d like to download the 2.0 firmware. Click Download Only – you don’t want to Restore just yet.
If for some odd reason iTunes doesn’t prompt you, we have a iPhone Firmware 2.0 for download. If you use this method, place the downloaded .ipsw file in ~/Library/Itunes/Iphone. Use Firefox to download the .ipsw, not Safari.
iTunes will then ask you a couple questions about downloading the firmware. Click Next, then Agree.
You will see the Download coming down in iTunes.
It is recommended to now sync in order to backup contacts, photos, mail, etc…
Alright, once you’ve downloaded the 2.0 firmware it’s time to launch PwnageTool by double-clicking the icon you extracted from the PwnageTool Download.
Click OK when the Copyright screen pops up.
Click the left image of the iPhone labeled ‘iPhone’. Then click the arrow button located in the bottom right corner.
On the next screen, PwnageTool will look for the 2.0 .ipsw file. If you let iTunes download it, or correctly placed it where I told you earlier (~/Library/Itunes/Iphone Software Updates), after about 30 seconds PwnageTool should find the .ipsw file and list it in the window. Click it then click the arrow in the bottom right to move on.
Click Yes on the dialog window below.
If you wish to unlock your phone click No if you are a valid AT&T user and simply wish to jailbreak your iPhone click Yes.
When it asks for the Bootloader v3.9 file, click No to the web searching, and instead then click Yes to browse on your comptuer to where you downloaded it earlier.
Do the same thing for the v4.6 bootloader file.
PwnageTool will now ask you where you want to save your custom .ipsw file to. Default is fine, but if you’d like to rename it and save elsewhere that’s fine.
PwnageTool will then begin to create your custom iPhone firmware. You’ll see the Building IPSW screen for a good 2-3 minutes.
Around halfway through the creation process you will see a window pop up, followed by OS X prompting for your password. This is necessary for PwnageTool to build the custom firmware, go ahead and input your password and click OK.
PwnageTool will ask if your iPhone has been previously pwned (and still is). If you aren’t sure, just click No, that is fine. If you know for sure its been Pwned and still is, click Yes.
Now we need to enter DFU mode to continue.
Simply follow the on-screen instructions to do so. Please do these EXACTLY WHAT THEY SAY, and WHEN THEY SAY. Timing is very important on this step.
Note: If you have any errors with entering DFU mode, open Terminal on your Mac (Applications/Utilities>Terminal.app) and run the following commands (You can just copy/paste straight from here, with a Return/Enter after each line):
cd ~/
mkdir “Library/iTunes/Device Support”
then try again.
Assuming you did it right, you will see the success message. Click OK.
Exit PwnageTool with Apple+Q or use the Exit button in the top right corner.
Now, pull up iTunes. You should see the following message:
Click OK. Now, hold down the option key on your keyboard and click ‘Restore’ in iTunes while holding it down.
Note: It is important you hold down the option key while clicking ‘Restore’.
Assuming you did that correctly, a window should pop up asking you which .ipsw file you’d like to restore from. Select the one we just created with PwnageTool. If you left it default, it should be sitting on your desktop and be named iPhone1,1_2.0_5A347_Custom_Restore.ipsw or something similar. Click Open.
iTunes will now run through its typical flurry of windows and notifications while updating the firmware.
You should now see the window stating your iPhone was restored to factory settings you can then click OK.
Wait for iTunes to see the iPhone before disconnecting.
Once the iPhone starts up for the first time, you might see BootNeuter 2.0 start up and let you know its going to flash the baseband and unlock your iPhone. When this is done it will return you to the new 2.0 homescreen.
Note: If you didn’t choose to unlock your iPhone, you won’t see BootNeuter.
You should now see this beautiful fully hacked iPhone 2.0 home screen.
I’m trying to do this with a 4GB iPhone 1st Gen. I’m unsure of the firmware. It’s never been activated or pwned. I’m running itunes 8 on a Leopard machine. I got all the way to the DFU mode, then itunes says it doesn’t recognize it, I never get to the screen with the option to restore, it just acts like it’s not there.
Thanks for any help you can give.
