Stuck at “critical software update is required” screen during startup

Hey guys,

I got similar problem on 06 -01-2021. My macbook pro is 15 inch with touchbar. after a lot of research I was disheartened by reading many blogs where the logic board replacement solution was provided by apple and for many they had replaced their laptops which were covered under warranty.

I changed the screen for a MBP 2017 with touchbar and afterward it get this problem, clean install and get this message at the end, solved by remove the screen cable from motherboard, since the t1 chip recognized the not original screen, then on the hdmi external, I got to the setup thing to finish my installation. Once done I plug back the cable lcd and now the Mac work normally, also I installed Sierra. Not latest osx

After exhausted all recovery method, I went to App Genius. Straight away they ask me to change logic board. I refused and I saw your post.
