Just a thought but maybe someone can make this working. Last month my brother got YLOD from his ps3 the first version JPN that came out, it lasted for 4 years then died I read that it's better to keep ps3 in non vertical mode to avoid YLOD hope it's true. Anyway this isn't the question. He gave me his HDD(60b) to put on my 40gb EU ps3 and i thought that i could take his savegames (most of them were mine) but the system forced me to format and then to update to the version i had on my EU ps3 it was 3.15 and my bro had 3.30 or something like that. Now i have 3.41. There is my question, if you change HDD it ask you to format and to update with the same version of your ps3, so i was thinking that MAYBE if you are able to modify files of debug version like we did with the CFW loader with debug setting through USB, and make a PUP of that: are we able to instal that "hybrid" firmware to a ps3?
