I own a PSA multi-15 and have always used synthetic motor oil. After watching this I believe I will run a small amount of high temp grease on my bolt. I always have heard people discourage the use of grease but they never offer any reasons why. Have you heard any excuses not for using it?
I had that problem. Just do everything manually.. If your ROMing it, might as well learn it, so u can undo if anything goes wrong. Learning will be very hard if u start once u brick your phone. I'm more than happy to assist you. +Brian Reed
