I ended up having to get a new 360 Elite (79FL) because my DVD drive on my old unit (79FK) crapped out. It wouldn't read any type of media: DVDs, Games, Backups, etc. I just took apart my new 360 today and installed my NME 1.2 chip into it, but I can't get it to work.I've done the following things to verify my installation:
- Tweaked the POT to many different levels (3.15, 2.98, 2.8, 2.7) and still getting Unplayable Disc, and Open Tray errors.
- Verified solder points using multimeter.
- Have not tried the Open Tray Fix (eg. adding 1mm of plastic to switch point)
I found a post on xbox-scene from someone saying they have installed an NME 1.2 successfully on a 79FL so I need to do some more testing before I have a conclusive answer as to if it's compatible or what my issue is.
