You'll have to take it to a service shop. They'll probably need to swap something inside the phone which costs over $90.

iGameGuardian is the most maintained and the best so far. Only downside is that it isn't free. GameGem is a great free alternative. GamePlayer is also really good & free, but it usually takes them 3+ months to update when a new iOS version comes and renders GamePlayer useless. Although, lately they're speeding up updates quite a bit. Hope it stays this way.

Droid4x or MEMu

I like iGameGuardian more.

Free Store feature is currently broken. It might get fixed on the next update. Until then, enjoy the other features.

Nice way to get started. Keep it up and welcome!

How easy was it?

Add a virustotal asap.

Seems complicated. There might be, but there might not be for 9.3.3 or lower. Jailbreak teams are shifting their focus to iOS 10 now.

Sbhacker for iOS has been discontinued. Look at GamePlayer, GameGem, iGameGuardian.

@ Has made a nice tutorial about this.

Try a different usb port?

No, just tell them the problem and see what they say. It's probably a hardware problem.

Reintall iTunes.

I prefer to use Droid4X. Quite faster.

Even though the installation gets stuck, does the tweak actually install or does it fail?

Probably the postinst that AppSync has might have changed something it shouldn't on newer iOS versions. Do you have a .deb to download the 3.1 AppSync?

Springtomize?

Uninstall Cydia Substrate and reinstall it. Then see if your home button is fixed.

I don't think you can without a tweak. Search through Cydia.

Did you install PPSync or something? What's that package? What if you install AppSync from AngelXWind's official repo?
