God eater burst save file

[dolanpls]

Hello.
A few months back i was playing GE:B on a galaxy S3,but the phone started to get old and a lot of problems began showing so i switched to another phone, but i didn't want to lose my progress so i copied the entire psp file on an external storage card, and today i wanted to finish my progress, but i'm having a massive problem, i can't use my old save files,i do have the save states plus i'm able to load them, but the game crashes the moment i enter a special menu (the weapon crafting one for example) AND when i finish missions (i had a save state in-mission),PLUS whenever i try to load it normally (in-game save) i just get sent back the starting menu. I get these problems both on pc and phone,and performance is not a problem.
Anyone has had the same problems? Any ideas how to fix it? Are the save states corrupted or something? Thanks!
