Don't forget to make a packup user.
A few minutes ago, something happened to me that made my heart stop. I had my jailbroken PS4 for a long time and had so many games and save files. And I was using Vue after free to jailbreak my console. A few minutes ago, Vue after free stopped working and the only way to fix it was to copy a custom save file to make it work again. I tried to copy the file and it didn't work, it kept showing me errors. I tried every solution and none worked. The only option I had left is to restore the data and that will obviously delete all my games and save files. Until I remembered that I had other three packup users. So what I'm trying to say is: always remember to make a packup user. ALWAYS. Because you'll never know when will this error happens to you. I know this is too much sentence for an advice, but I hope people would listen to it. Because a lot of people only use one main user.
