lately, I've got a second-hand iPad pro and its like 3 years old. I jailbroke it soon after with unc0ver and now some functions do not function properly. The screen light out won't work for some time. If I turn off it and on the alarms are going insane. Sometimes images are not previewing and just exit it. I don't know if these issues are with it before I jailbreak it. Any suggestion to fix it? Thanks.
