What are you looking to spend?

Use Taig. It gives better results. Let me know how it goes, if you get stuck notate the percentage you got stuck at.

try to turn on AirPlane mode, and also disable Location Services (Settings > Privacy > Location Services) via the Settings app. That is assuming you've turned off your passcode and also your find my iphone functions.

Are you using a Virtual Machine?

Yeah I tried to explain it to him but he went ahead and updated anyway lol. Pretty sure he had another thread that @Alyce merged with this one. It was a big jumbled mess.

He updated from iOS 8.2 to 8.4 lol.

1929?

Just backup your stuff periodically and if something doesn't work ALWAYS boot into safe mode first. If it starts working after you do that then it's a tweak you installed. Look at your installed section and sort it by recent and you'll be able to see what you installed last. After that it's just trial and error till you find it.

You could've also redownloaded Cydia through iFile if you had it. Oh well.

Like did you put your device into safe mode by restarting your device and holding the volume up button while it boots back up.

Did you boot into safe mode? This would disable the tweaks you have. You didn't delete Cydia, it disappeared.

What iOS version are you guys on? Maybe it's apple subliminally attacking other media providers to force people into using apple music.

Still have to download from a third party host and it's usually appcake, appaddict, or a hosting site.

Maybe it's just a really shitty update lol.

I like to also just because of compatibility issues and also because it gives me a chance to get rid of tweaks I installed and forgot about lol. Which is a surprising amount. But generally people are hesitant to update because they don't want to go through the hassel of re downloading everything.

I don't think running HD is his issue. From what it sounds he is having trouble even keeping the app open. Topic was a little scarce on info. You're 100% sure that you were on safe mode? Post how you booted into safe mode to make sure you did it right.

Use PkgBackup to save your jailbreak when updating. You can find it here.

Use PkgBackup and back up all your tweaks then restore your phone and rejailbreak. It'll prob be the easiest fix then trying to troubleshoot it and you won't lose all of your stuff.

Was there something you did just prior to this happening? Like installed something or changed some kind of font or maybe the status bar?

I know what you mean though. Spotify makes me log in every single time I open the app because of Xcon. It sucks lol. But beggars can't be choosers, ya know?

Was going to say the same thing. It's to exploitable and they know it so they phased it out.

Nope, doesn't have flipswitches to blacklist apps.

Have you tried booting into safe mode. This would be the next step.

I need an Enema.
