1. Confirm which Firmware you’re having on your device
a. if it’s 3.0.x you can install from the Big Boss Repo
b. if it’s 3.1.x you have to install from our own Cydia Repository (see here how to add the repo)
2. If the App doesn’t start after the installation, it most likely is because of the missing Documents Folder within the //var/mobile/ Folder of the Device

So, then SSH into your device. As first create the missing Folder and then copy the file ‘myWeek.sqlite’ from the Applications Folder into this Documents Folder.

Afterwards restart the Device and launch myWeek, should work now.
