Try to begin the phone as traditional, however when 1-2 seconds, hold the facility and residential button at identical time for some seconds, the screen ought to return on when some seconds. My S5 had this issue and it worked for it, therefore hopefully this may work for you. 

If you are doing manage to induce that shodden up this fashion for you similarly, you'll wish to see out golf stroke your device into Safe Mode. this is often attending to rule out if any third party apps area unit the foundation cause behind this. that might be one among the variables that differs between your device and your wife's.

If that happens once more, enter recovery mode by holding the facility button, home button, and volume up button.  From the menu, use the quantity keys to pick up or down, and wipe the cache partition. try and boot.  If that does not work, return into the recovery menu victimisation the steps i discussed, and now, wipe all knowledge. that's essentially a tough manufacturing plant reset.  Yes, it's a pain within the rear to line up the phone once more, however a minimum of it ought to work. 

Once you've got it reloaded, and every one of your apps area unit put in, boot to safe mode and check out to work out if one among your apps is inflicting it.  If it's not associate degree app, then there's a setting that's being set either by intent or unintentionally.

That would be.  If the LED case quit operating attributable to associate degree electrical short, the management app for it should have thrown a kernel panic and threw the phone into a boot loop as a result of it thought there was an interior error.  At that time, the error was set once there very was no error. 

I still suppose long pressing the facility, home, and volume up keys to induce into recovery and doing a manufacturing plant reset can work if you are doing try and use the case and it happens once more. i'm basing this theory off of the approach that a UNIX based mostly kernel (the design that robot operates on) can panic if there's even a small electrical drawback within the internal hardware or any peripheral hardware that may create itself boot over and over agin in an endeavor to resolve the problem.
