A dozen 2018 Airs all overheat and reboot attempting internet recovery
Hey All!
So this is a weird one -- recently acquired from recycler a dozen 2018 Airs. All great shape, all power on, all wiped. However, when they attempt Internet Recovery, they sit there forever, and after an hour they overheat and reboot. I have also tried connecting to ethernet, and multiple Internet sources, so I know weak connection is not the problem.
These are not locked, but they have the default security utility setting for a 2018 which disallows booting from an external drive, so that is not an option. I have tried wiping in DFU mode, and that did not change anything.
Anyone have ideas? I keep thinking GPU issue, but very odd that a dozen machine would have exact same symptoms.
Also, look at this picture -- the progress bar looks weird. Never seen it like that, and they all look like that.
Thanks!
John

Can you post pictures of the front and back of the board please?

@guardian10 I don't have any of them open. They are just 2018 Airs. What would you be able to identify from seeing the boards?

@rdklinc Broken traces, components, etc. Maybe I'm barking up the wrong tree, though.

When you wiped using DFU mode, you did a restore? Or a Revive?

@flannelist Interesting! I did restore, so I just tried revive, and after 20 minutes it says "system cannot be restored on this device, gave up waiting for device to transition from DFU state to DFU state". What does revive do exactly? Thanks!
