PS3 How does Hybrid FW modify the detection mechanism through the PS3 upgrade program?

That's the thing. If V1.90 sprx has no checks then it isn't signed. So how can unsigned exectuables run on OFW 4.84?

that's what i mean early hhhh cause OFW nowdays have checker if can't found a signature like it have 0000000000000 and that doesn't exist in the database of the checker so it will reject causing a softbrick and an update from recovery is needed

I'm not sure about that. Is that true @sandungas, You've told me once that files that were too old wouldn't work?

Replacing Original sprx files with a bit older one does work but I don't think getting the game_ext_plugin.sprx from v1.90 will suffice for 4.84. Has anyone tested this?

I think game_ext_plugin.sprx from 0.90 is going to have lot of problems to work on 4.84 because there was many game related functions implemented along time in PS3 firmwares, probably the 0.90 version was minimalistic, so some functions of game_ext_plugin.sprx could work (because modern firmwares trys to keep backward compatibility with older firmwares), but other functions dependant of it are going to be broken
