How To Install iOS 7 beta 4 Free, Security Flaw Demonstration – Education Purposes Only
Today, after fully restoring all aspects of their iOS Developer center and three weeks after issuing the third beta version of iOS 7, Apple seeded iOS 7 beta 4 to registered Developers. In Apple’s continuous effort to prepare iOS 7 for a public release this fall, the latest iOS 7 beta is the most responsive yet. After running a number of tests, the staff here at Jailbreak Evasi0n have reported reductions in overall lag and the correction of some obscure glitches present in the past three 7.0 betas. Unfortunately, although iOS 7 offers new features and significant visual enhancements, similar to iOS 6.1.3, the new firmware isn’t able to be jailbroken. Additionally, individuals who update their newer devices from a jailbreakable firmware (iOS 6.0 through iOS 6.1.2) will regrettably forfeit their jailbreak because devices on iOS 7 can only revert to the latest public firmware being signed, which is currently iOS 6.1.3 or 6.1.4 for the iPhone 5.
In spite of the obvious limitations, we know some will decide to upgrade to iOS 7 months before its upcoming release this fall. Therefore, in this article, we’ll discuss an iTunes update security flaw that bypasses Apple’s UDID developer registration check, which allows any user to easily upgrade their device to iOS 7.0 beta 4.
Before highlighting the method to upgrade to iOS 7 though, it’s important to mention that this article is simply an educational exposé (along with the sample video below) to showcase a flaw in iTunes’ method for handling update requests. Although it may seem obvious, we will not provide any direct download links to iOS 7 beta 4, as that would be a direct infringement of Apple’s copyright. When undertaking a feat such as this, know that you assume full legal responsibly if you decide to update without registering an iOS device’s UDID through Apple’s Developer program.
Step 1: Ensure that your iPhone, iPad or iPod touch is on the latest public firmware, which is either iOS 6.1.3 or iOS 6.1.4 in the case of iPhone 5 owners. If your iDevice happens to be on an older version of iOS 6, or if it’s jailbroken, proceed to the second step – those users with devices on either iOS 6.1.3 or 6.1.4 can skip to the third step.
Step 2: Create a full backup of your iDevice inside iTunes, restore to either 6.1.3 or 6.1.4 and, finally, restore from the backup that was previously created through iTunes.
Step 3: Launch the latest version of iTunes – if you’re uncertain as to whether the program is up-to-date or if your computer happens to have an older iteration of iTunes installed, take the time to upgrade now.
Step 4: Navigate to the device tab inside iTunes, hold down either the option (alt) key on OS X or the shift key on a Windows-based computer and left click “Check for Update”. At this point, you should browse for your device’s corresponding iOS 7 beta 4 IPSW – again, for legal reasons, we cannon provide direct download links to our readers.
Step 5: Once the firmware has been selected and the device completes the automated update process, follow the straightforward iOS setup process on the device itself.
Hypothetically speaking, following the instructions listed above will successfully install iOS 7 beta 4 on an iPhone, iPod touch or an iPad. If you find yourself at all confused by the detailed steps outlined in this article, we strongly advice following along with the instructions given in the video embedded above.
