Updating APIM Firmware (Calibration Files)

I’ve got the flickering issue on the Sync screen with post-19101 versions of Sync 3.4. I recall there being a potential fix for that by changing the illumination strategy in the asbuilt, but I think to get an option for C1MCA I need 3.3 or 3.4? Maybe I’m misunderstanding this post of yours: Sync 3.4.21194 - Feedback & Issues - #256 by F150Chief

I have no idea if it will even work to get rid of the flicker–I know a lot of Focus/Kuga/C-Max people are plagued with it. I could of course go back to 3.4.19101, but wanted to try this.

Let me know what you think! Thank you.
