I have an iPhone 7 jailbroken with match portal. I was using my phone and it randomly shut off and it is stuck on the white apple logo. I have tried restarting the phone multiple times holding the volume down and power button but it goes right back to the Apple logo. iTunes does detect the iPhone but it says I need to enter in my passcode to access it which I can't. I don't have money to go to workshop. Any help (ifixit guide/tutorial/video/tips) would be greatly appreciated.
