I have read suggestions for various problems that a factory reset should be tried. I can get into tsst ode by holding down quick and left arrow while pressing home. Once in that mode I can press menu and be presented with a laundry list of test options. Which is used to execute a factory reset? I thought perhaps it would be ROM option which presents a EEPROM check option with options READ and WRITE. If I select write it says “are you sure?” I am not sure. Is this a refresh of the boot settings? Help!
