IPhone refusing to be locked?

I have an iPhone (c or s? I have no idea lmao, which ever one is with the gold on the back.) I've jailbroken my phone and it was fantastic, but now everytime i hit the lock button on the top right of the phone, it goes to the lockscreen but it won't go completely black. This is So annoying, if anyone could help me that'd be great!

Two things. Either soft reset the phone or remove the jailbreak.

  • YouTube refusing to download on new iPhone? Okay, I just got a new iPhone, and when I say new, I mean I literally just left the store and I typing this message out with it. I saw YouTube was having a hard time refreshing and it took a bit, so I thought "No biggie, I'll just uninstall then reinstall it" I hit the little cloud icon on the app store to redownload and it did nothing! Any ideas on how to fix this?

  • How to reboot an iPhone that's locked and has Find my iPhone mode turned on? I found an iPhone, and I want to reboot it. But I can't quite do that at the moment because "Find my iPhone" is on. And it says I need to turn it off before it can be rebooted. But since I found the phone… I don't know the password, so I'm not able to access anything. Please help me if you can, I'll really appreciate it.
