Alright, So I swapped my HDD from a 160gb to a 500gb drive. I know how to reinstall the firmware from the safe mode and recovery mode thing. But every time I go to reinstall it either says "No Applicable Update Data Found" or "The Data is corrupt" Every flash drive I tried it gave the same results. And yes, they are all fat32 and set to mbr. The flash drives work too. I'm just trying to reinstall stock sony firmware so I can rejailbreak.
