I have an iPhone 5S stuck in restore loop, due to cydia being corrupt. I did attempt to restore, and jailbreak again. I have an appointment at the apple store at 7:20 EST TOMMOROW. F.lux will tint the logo and bar, and they may be able to identify it as jailbroken. iFunBox sees the phone as jailed due to the restore process. Help?
Hey there! I know what you are facing so I'll try to help you the best I can. Firstly try to put it into DFU mode.
Steps:
1) Power the device down
2) Start holding Power button for 3 seconds
3) Hold Home button but don't let go of the Power button, 10 seconds
4) Keep holding Home and let go of Power. About 15 seconds just to be sure
Make sure that your device is in full blank screen without any apple logo or anything. Connect your device to your computer and now iTunes should detect it in recovery mode/your computer will first detect it in DFU mode.
Just restore and voila! Hope i helped!
