iPhone 3G 2.2.1 Custom Restore Firmware
iphone 3g 2.2.1 firmware
By coderetard
The newest iPhone 3G 2.2.1 firmware update from Apple was released earlier this week and iPhone Dev Team’s Pwnage Tool has just been released yesterday. With PwnageTool, you can create your own custom iPhone 3G firmware from Apple’s official IPSW file so that you can continue to run the yellowsn0w software unlock. The 2.2.1 firmware update contains a baseband firmware update (02.30.03) which is not compatible with yellowsn0w.
This is a major problem for iPhone 3G users who wish to update to 2.2.1 firmware but still want to keep their iPhones unlocked to use outside of AT&T. This is only possible with a custom firmware created with Pwnage Tool that strips out the baseband update from the upgrade. This is great… if you have a Mac. Windows users are left in the dark for now, at least until QuickPwn for Windows gets released.
But if you don’t want to wait, we’re actually providing the custom IPSW firmware as a free direct download created with Pwnage Tool for you to update your firmware without needing to wait for QuickPwn for Windows to come out. This only works, however, if you’ve previously pwned your iPhone before.
With this firmware update, you simply need to put your iPhone in DFU recovery mode, launch iTunes and shift-click (Mac users option-click) on restore and browse to this custom firmware and use it to update your iPhone’s firmware. And that’s it. Since you’ve previously pwned your iPhone before, QuickPwn isn’t necessary for you and you won’t need to wait for QuickPwn Windows to be release. If it hasn’t been pwned before, then you’re out of luck and you’ll need to wait.
- Download the iPhone 3G iPhone1,2_2.2.1_5H11_Custom_Restore.ipsw from us (MD5 sum = 93c379cb80b573c41580bfb56619ff34). This excludes the baseband upgrade so you can be sure 2.2.1 will be compatible with yellowsn0w unlock. It also contains Cydia and Installer. The custom boot logos were excluded.
- Connect your iPhone via USB cable and put it in DFU mode. To put it in DFU mode, turn the phone off. Hold power and home together for precisely 10 seconds. Release power but keep holding home until the pc beeps as a USB device is recognized. At no point will the display come on. If this doesn’t work, try to press and hold power only. Keep holding power. As soon as you see any display on the screen of any sort press and hold the home button. Hold power and home together for precisely 10 seconds. Release power but keep holding home until the pc beeps as a USB device is recognized.
- Launch iTunes and shift-click on the Restore button (option click for Mac users). Then browse to the custom restore 2.2.1 firmware you downloaded from us and let iTunes do the rest.
- Once your iPhone has been jailbroken to 2.2.1 firmware, follow our yellowsn0w soft unlock guide to unlock your 3G iPhone if so desired, starting from step 9.
Remember, this shortcut is for previously pwned iPhones only. You don’t need QuickPwn to upgrade to 2.2.1 if you can get your hands on a custom restore firmware like ours.
