How to Start the Overwriting a Wrong Quest
To begin the Overwriting a Wrong side mission in Borderlands 4, speak with Terry in the Witness Construction Program area in the Carcadia District of Dominion.
How to Complete the Overwriting a Wrong Quest
Upload a virus into a prototype killer drone, and maybe you’ll make them significantly less homicidal.
Find complete drone
To enter the facility, use the grapple point behind Terry. Once in the facility, head left to find the complete drone and interact with it to start the virus upload to drone.
Reach first jammer
Once you’ve started the upload, the signals will jam. To reach the first jammer, head to the southern side of the building. When you arrive, interact with the console to hack it. To destroy the nodes floating above the console, shoot the red triangles.
Hack second jammer
In the same room as the above jammer, you’ll find the second console. Hack it then destroy the second jammer’s node by shooting the red triangles.
Hack third jammer
To find the third jammer, head south and use the grapple point. When you find the computer, hack it then shoot the red triangles.
Return to drone
Make your way all the way back to the drone. Once you arrive, use the drone then shoot the red triangles and wait for the code to compile. As it compiles, enemies will appear. Take them out then shoot the red triangles as needed. The mission will then end.
