Step 1: After Downloading the files above, extract the files from the Cydia Impactor 0.9.43 archive to a folder on your desktop and then open your iTunes and connect your device.
Step 2: Run Impactor and allow it to read your device. Log into your iTunes account in your Web browser via appleid.apple.com and your will have a 6 digit security pin sent to your device, punch that in at your login to access your security settings.
Step 3: Scroll down till you see "App Specific Password" and select generate, label the generated code "Impactor" and then copy that code using Ctrl+C on the keyboard.
Step 4: Navigate to your Cydia Impactor and take the Yalu112.IPA and drag and drop it into the Impactor, punch in your Email for your Apple ID and then paste the App Specific password in and hit continue and wait for Impactor to install the custom IPA.
Step 5: Unplug your device and scroll to your settings and go to General/Profiles and select your Email under Developer App, Select trust and then exit your settings.
Step 6: Scroll to the Yalu icon and open it, the top link will install Cydia Mirror, the other will install the TweekMo App one youve done that if you have a Developer account with Apple, you can now install the Cydia Extender to use the real Cydia.
NOTE: This is not a complete jailbreak!! If you do install the Cydia substraight via Impactor after installing the Mirror via Yalu, you better know what your doing.
