So I was having trouble with my 3.71 custom release, and I realized I had a 3.52 M33 installer sitting on my memory stick. I decided to give it a whirl, and everything validated, etc. however after the installation apparently completed, I tried to restart and gota problem. The light turns on for about 30 secs, and I get a black screen before it turns off. No attempt to read the MS, etc.
Am I committing a user error in getting back into my FW, or did I actually brick it?
