I do have what I believe is Trinity, matt finish, mfg date of 2010-08-07, and power cord that is 10.83a. This is a 4gb model, that will need to be upgraded for use but, it looks like a good starting point.

This should be on a current or a few steps behind dashboard, not sure if that will effect things.

I saw this, an ACE v3, I assume this is what your referring to.

I grabbed this flasher...It appears it will do what I need..

Unless I am wrong ?

Never modded a 360 before. I did a few RROD fixes so I have been inside them but, not modded.

Thanks !
