Here is a method to re-install Cydia if you have too many bugs, without any restore or re-jailbreak.

Required :
  • A jailbroken iPhone
  • Cydia.deb
  • Mobile terminal installed from Cydia




Connect to your iPhone with SSH and transfer Cydia.deb into root/User/
And then, start Mobile terminal.





Type « su » then your password (alpine by default)
And then type « dpkg -i /User/Cydia.deb  »

If you still have some issues, Restore + Jailbreak are the only way to solve them !
