Is my console Trinity or Corona? You can see my xbox images at .
That is a good start but the only way to confirm is to open the system and look at the Nand points. Trinity is 2 sets in parallel while the corona is 2 sets with one of them turned 90 degrees.With that manufacture date it should be a Trinity motherboard.
According to WeekendModder:
Slim S:The nice thing about the Slim series is that there are only 2 possible motherboards within them:
- Trinity (Most consoles with a MFR date of 07-2011 and BEFORE)
- Corona (Most consoles with a MFR date of 8-2011 and AFTER)
