So you’ve jailbroken your iPhone running iOS 7 with Evasi0n but are running into problems getting any of the tweaks installed through Cydia to work. Well, here’s how to fix it.

  1. Open Cydia.
  2. Go to Manage. Then Sources. Click Edit at the top right, then tap on Add at the top left.
  3. Enter this source in the URL field: http://repo.cydiahacks.com
  4. Click on Search, and look for ‘Bootstrap’. Install.
  5. Search for ‘Mobile Substrate’ and re-install (you most likely already have this installed, just click re-install).
  6. Respring.
  7. Install Cydia tweaks as necessary and everything will work just fine.

Hope this works! Comment below if you still can’t get it going.
