Install iOS 7 beta 3 – Security Flaw Demonstration
Yesterday, two weeks after issuing the second beta iteration of iOS 7, Apple seeded iOS 7 beta 3 to registered iOS Developers. Thankfully, Apple’s latest beta version of iOS 7 is the smoothest yet – numerous Developers, including those here at Jailbreak Evasi0n, noticed significant lag and several quirky glitches in the first two 7.0 betas. Unfortunately, while iOS 7 offers drastic visual and operational enhancements, as with iOS 6.1.3, the firmware isn’t able to be jailbroken. Moreover, those who update their newer devices from a jailbreakable firmware (iOS 6.0 through 6.1.2) will regrettably forfeit their jailbreak, considering devices on iOS 7 can only revert back to the latest public firmware that’s currently being signed – iOS 6.1.3 or 6.1.4. However, we’re fully aware that some will decide to upgrade to the firmware months ahead of its public release in fall. Therefore, in this tutorial, we’ll highlight an iTunes update security flaw that bypasses the required UDID Developer registration check so that any user can easily and effortlessly upgrade their device.
Prior to beginning though, it’s crucial to mention that this is simply an exposé article (along with the embedded sample video below) to showcase and demonstrate a flaw in the way iTunes handles update requests for educational purposes only. We will not provide any direct download links to iOS 7 beta 3, as that’s a direct infringement of Apple’s copyright. Although it almost goes without saying when undertaking a feat such as this, know that if deciding to update without registering an iOS device’s UDID with Apple, you assume full legal responsibility.
Step 1: Verify that your device is on the latest public firmware, which is either iOS 6.1.3 or 6.1.4 in the case of iPhone 5 owners. If your iPhone, iPad or iPod touch happens to be jailbroken, or its not on the latest version of iOS, proceed to the second step in this tutorial – those with devices on either iOS 6.1.3 or 6.1.4 can skip to the third step.
Step 2: Initiate a full backup of your device inside iTunes, restore to the latest firmware and then restore from the backup that was created through iTunes.
Step 3: Launch the latest version of iTunes – if your computer happens to have an older iteration of iTunes installed or you aren’t certain whether its up to date, take the time to upgrade now.
Step 4: With iTunes open, navigate to the devices tab, hold down either the option (alt) key if on OS X or the shift key if on a Windows-based computer and left click “Check for Update”.
Step 5: Browse for your device’s corresponding iOS 7 beta 3 firmware file – again, for legal reasons, we cannot provide our readers with direct download links.
Step 6: After the firmware has been selected and the device completes the update, follow the new simple and straightforward iOS setup process.
Theoretically, following the above steps would successfully install iOS 7 beta 3 on an iPhone, iPad or iPod touch. If you’re at all confused by the detailed procedure outlined in this article, we strongly recommend following the steps given in the video embedded above.
