Mobile Substrate has yet to receive the update that will bring full iOS 7 and 64-bit support to it. Due to incompatibility of this very important Cydia component many users are facing problems with their jailbreak. Users are reporting frequent crashes and Cydia tweaks not working on their devices.
The issues include tweaks not working at all or not showing up in their settings.app where they can configure them. Good news is that there’s a simple fix to this problem. All you have to do is reinstall the Mobile Substrate. While it is not fully compatible with the iOS 7 jailbreak reinstalling it does helps.
Here’s how to fix the tweaks not working problem.
- Open Cydia and tap on the ‘Manage’ tab.
- Now tap on ‘Packages’. On the next page look for ‘Mobile Substrate’ from the list.
- Now from the details page tap on the ‘Modify’ button and then on ‘Reinstall’ option from the menu.
- After installation is complete simply respiring your device.
Tweaks should start working on your iPhone, iPad or iPod touch.
