How I solved the problem with completing "Feros: Data Recovery" AFTER you've completed the main Feros story and you lose access to the elevator. (PC only)

While standing in Zhu's Hope (after you've completed the main Feros story), and you've got the 'Data Recovery' mission active - type this into console "at BIOA_WAR00 Start_WAR50_10"

It will teleport you to the area with the computer that you have to access.

*Next, after accessing the computer, type this into the console "at BIOA_WAR00 Start_WAR40_11"

It will teleport you to the area where you first acquired the Mako on Feros. This is the BOTTOM of the elevator that leads up to Zhu's hope, which was (and is) closed at the top. Take the elevator up and complete the mission.

---- Important

**** DO NOT take it upon yourself to look up the code to teleport yourself back to Zhu's Hope directly, the code available takes you to the wrong instance of Zhu's Hope - a sort of 'halfway' between starting and finishing the Feros main story. You will not be able to complete the Data Recovery mission if you do this. You must teleport to the bottom of the elevator, where you first acquire the Mako.
