If/when you can sync with PSN, by whatever means, it’ll likely put you at risk of getting banned. Play honest. Don’t be a dick.
Inside the trophy collection section on your XMB, there are games represented by thier TROPUSR.DAT(s) respectively, where you can view the % of a game, what have you unlocked, etc. TROPUSR.DAT stores all of that information. Basically to get everything unlocked on a game, you will need to edit that game’s TROPUSR.DAT.
Manually editting TROPUSR.DAT can take a while to get used to. But after learning where and which byte to change, you will be able to platinum a game in no time.
