i apologize ahead of time for this really noob question. I have looked everywhere for answer and I am just getting more confused. I currently have the official firmware version 1.52. Can I install M33 3.52 directly? or do I have to upgrade to 2.0, then downgrade to 1.5 and then upgrade to M33 3.52? or should I upgrade to Sony's official 3.52 then to M33 3.52? Also if I have to do the first step where can I find 2.0 firmware since sony only has 3.52 available right now as upgrade. any help would be appreciated.
