Not Solved - Quest 3 stuck in firmware update loop
A few days ago my Quest 3 rebooted by itself, showed an icon of a chip with an arrow pointing to it and a green progress bar, which most probably means it's trying to update the firmware. Since then I've tried literally everything, multiple reboots, factory reset, sideloading an update via the Meta web page (error connecting to device), got several firmware versions from cocaine.trade/Quest_3_firmware and sideloaded them with adb (which at least _appeared_ to do something), but the problem persists: After every reboot the device goes into that firmware update mode and after it, it's a black screen.
Meta let me down... refusing any meaningful support and also the replacement of the device on the grounds that it's half a year out of warranty. I loved the Quest 3, but this horrible attitude towards the customer is shocking.
