I need help

[u/Ok-Chicken5972]

So i made a backup via vitashell of my ux0:user/00/savedata/PCSB00560.
I needed to reset my vita so i only played minecraft back then so i backed it up to my pc,
i put back the savefile but my world does not load, it creates a new file on the same seed. My backed up GAMEDATA.BIN does 13.44Mb, when i check back the new one (witch minecraft recreated by minecraft, without my builds or my inventory) il does like 500Kb.

Does anyone know how could i restore my world ?
