For people who are too lazy to click on the thread that is literally at the top of the website....
Hello again,
Since Apple changed app's location again, some hacks won't install properly on your iOS 9.3, 9.3.1, 9.3.2, 9.3.3 device. In order to fix this and make the hacks work, you will need to follow these simple instructions for the hacks which aren't 9.3+ updated yet.
Step 1: Using iFile or Filza (Filza is suggested), navigate to /var/mobile/Containers/
Step 2: Tap on the 'Edit' button, then on the 'Create New' section, tap on 'Symbolic Link'.
Step 3: Then on the new window, you will need to select the folder located in /var/containers/Bundle/
Step 4: Once you've selected the Bundle folder, tap on the 'Select' option and the new symlink will be created.
Step 5: Now simply install the old .deb hack and everything should install and work properly.
