Gaming Really quick question regarding Gen A, B, C

[ShinraArmy]

Im updating a PSP Fat to 5.50

I installed Gen A succesfully, then Gen B, now im not sure if im supposed to move to B2 or D..and from D to D2 or D3...?

Just ignore whatever firmware you are on and just get the 5.50 GEN-D3 final, and install that. You do not need any prerequisite to install it except having an previous custom firmware.
I went from 5.00M33-6 to 5.50 GEN-D3 final. I say "final" because Gen re-released 5.50 GEN-D3 because their was a couple of bugs, nothing big though.
