A lot of people have managed to jailbreak their iDevices, but still Cydia continues to throw errors at them, right and left. This article reveals a solution for the DPKG LOCKED cydo and Cydia returned an error code issue on iOS 11.3.1 – 11.0 jailbreak.

Cydia gives the “DPKG_LOCKED” & “cydo returned an error code” messages on several occasions, when –

  • Cydia installation is corrupted.
  • Cydia isn’t properly installed on an iDevice.
  • There’s an error on part of the user.
  • Jailbreak is using an outdated or bogus version of the package manager of Cydia.

Fortunately, though, the old tested Delectra script still functions for Electra1131 even though it hasn’t been updated by the developer.

The script can be easily used to clean Cydia installations and jailbreak the device from ground up again.

What You’ll Need

  • WiFi connection.
  • iOS 11.2-11.3.1 firmware.
  • iDevice (iPod, iPad, or iPhone).
  • Uninstall script for Delectra.
  • WiFi network.
  • PC running macOS or Windows.
