J'ai trouvé la solution et elle marche pour les gens qui sont interessés sur le forum bioware
Start by downloading Gibbed's Mass Effect 3 Save Editor.
Run the Editor. Press Open on the top bar, and select the appropriate career and save file.
Select the Raw tab and scroll down to Other. From here, find the category that says "Streaming Records" and click on it, then look to the far right of the table for the [...] looking button . Click on that.
Find the "Add" button at the bottom of the box, and create a new entry named "SS_HanarPlot" (no quotation marks!) and set the "Active" option to "True". Hit OK.
Don't forget to press the Save button at the top before closing the editor! Start ME3, load your file, and the terminal should be active again!
