back in 2016 i saved the old URL link for the 3.60 firmwire for Asia Model VitaTVs to my bookmarks, and it seems that the URL is still active to this day so i went ahead and downloaded the file to my computer. right now i would like to update my asia model VitaTV with the old 3.60 update file that i just downloaded, but i'm worried that the file could infact be a 3.63 update in disguise and thus i'm too terrified to even put it in my vita. so what should i do now? how do i know that the 3.60 update file i have is indeed a 3.60 update, and not the newer 3.63 one? please help and many thanks!
