I’ve had some power issues over the past few weeks with power to appliances being cut off mid operation. In the past 24 hours I’ve had my two 3rd gets 128GB 4K units get stuck in a boot cycle with the white light flashing. Our iStore’s aren’t official Apple stores, just premium resellers. When i took the two units to the closets iStore they told me the white flashing light was indication of hardware failure and since both where out of warrentee I had to replace both units. I replaced the one so at least the family had one working unit. Question, if I had a proper Apple iStore look at the units, would they not maybe be able to restored the software? Not buying it’s a hardware fault on both. Travelling to the USA in a few months. Thinking of bringing the two units to a proper Apple for their opinion. Any thoughts?
