Prepare your device

Step 1 First and foremost, ensure your device is in jailbreak mode. If it isn’t, re-jailbreak your device by following this guide.

Transfer the uninstall script to your device

Step 5 Launch CyberDuck SSH utility and click on Open Connection.

We will demonstrate this process using macOS Mojave but you can perform all steps on Windows as well.

Step 6 Select SFTP (SSH File Transfer Protocol) from the protocol dropdown list. If you set it to any other option, you will not be able to establish an SFTP connection.

Step 7 Enter the following details to establish an SFTP session –

  • Server – Your Wifi network’s IP address you noted in step 4 above.
  • Username – root
  • Password – alpine (default password)
  • SSH Private Key – None (default)

Step 8 Cyberduck will now warn you about an “unknown fingerprint”. Click Allow to move on to the next step.

Step 9 Transfer the shell script to the /private/var/root folder by dragging it onto Cyberduck’s window.

Remember, this is the default folder and contains only two sub-folders (Application Support and Library) and a file (files.list).

Execute Delectra script

Step 10 On your Mac, close Cyberduck and go to Go > Utilities. If you are on Windows, you must use PuTTY telnet client that you can download from this link.

Step 11 Open the Terminal app.

Step 12 You would now want to log in to your device as root. Enter the following commands –

ssh root@<IP Address noted in step 4>

Step 13 Terminal will now warn you about the authenticity of the host and will ask you to continue or abort the session. Type in yes to continue.

Step 14 Type alpine in the “password:” field and wait for it to log you in. Remember, you must use your custom password if you modified it before.

Step 15 Type the following command and hit enter/return key to execute it.

bash ./

Jailbreak your device

Step 16 Once the script removes jailbreak from your device, it will go back to its original stock firmware version. Restart and jailbreak your iPhone/iPad using Electra1131.

That’s all there’s to it! You will now be able to install your favorite Cydia tweaks without DPKG_LOCKED and cydo returned an error code messages pestering you.
