iPhone 12 bricked overnight. Possibly due to unknown update.
Hello, my iPhone 12 appears to be bricked currently. This issue began at approximately 2:01 AM 9/7/2023 EDT. The device was working properly before going to bed, there was not even an alert of an automatic update, although according to Life360, at 2:01 AM the device appeared to have lost signal. The device was brought to apple today, they said they've "never seen this issue before" and could not help. I've tried putting the device into DFU mode, although the phone did not appear to iTunes or my desktop. I have seen an issue similar to this appear online which was solved by replacing a faulty earpiece speaker and I'm wondering if there is a component I can troubleshoot and replace myself as I own an iFixit Pro Tech Toolkit.
Is dit een goede vraag?
