How to fix BloD (never ending bootloop) on a Jailbroken iPhone?

After installing Cydia Substrate (Of course I didn't know that tweek is causing problems) and trying to reboot my iPhone, I got into a never ending BootLoop. I have tried everything- the Volume up trick, every single software and any other thing that a really long google search could give me. IIm stuck.

Restore it using iTunes

  • Updated iphone 4 to iOS7 ending phone calls? I can do everything on my phone from receiving messages and sending, but i can't make phone calls. It does not ring it only says "call ended".

  • My contract is ending soon and I plan to buy an iPhone 5s but? There are media rumours that iPhone 6 is coming out very soon. Do I really have to buy the latest model? What if there's an iPhone 5s and there's a big difference between the two models? I can wait but still I would like to have the iPhone (either) soon.
  • Mobile contract ending soon? Okay so, my friend's contract on o2 ends in 11 days. She had the iPhone 4 and is wondering what happens when this contract is up. Does it just end or are you still charged for your bill? Please, no links and explain it simply. What would she have to do to just end it as she wants a new contract for the iPhone 5 but doesn't want to upgrade.
