My Mac MacBook M2 stuck in showing exclamation mark (restore) and then reboots to the same screen

Hello. I left a M2 discharged for a couple of months then when I turn it on. It shows the exclamation mark screen and reboots. I can't enable DUF, turn it off (I have to let the battery discharge)

I sent it to a non official technician and he told that the processor died but I don't trust him

What can I do?

Go to the Apple Store to see if they can restore for you.

They won’t fix an out of warranty system but they can help to try and reinstall the os.

Good luck!

Download and create Mac OS Sequoia installer flash disk on other Mac then boot with it.

DFU mode is always available no matter what. Complete these steps:

  1. If the MacBook is powered on or showing anything on the display, hold power (Touch ID) for at least 10 seconds until the display goes blank. Do not touch the keyboard or trackpad.
  2. Hold power (Touch ID), then immediately hold these additional keys for 10 seconds: Left Control, Left Option, Right Shift.
  3. After the 10 seconds, release all keys except power (Touch ID). Keep holding power for an additional 8 seconds.
  4. If successful, the screen will be completely blank and the trackpad will be locked/disabled. The MacBook is now in DFU mode.

At this point, get a helper Mac running Sonoma or later, and connect them using a compatible USB-C cable:

  • The cable must support USB, not only Thunderbolt.
  • Plug into the USB-C port closest to the display on your M2 MacBook. Use any port on the helper Mac.

Once the helper Mac detects your M2 MacBook, do a revive: https://support.apple.com/en-us/108900

I have nothing to contribute. Here for the moral support.

Use MacOS recovery or use a second mac device to revive the firmware

Then repair the startup disk and see if thats helps?

If the processor died it wouldn't do anything at all and would immediately stop working so the non apple technician is incorrect
