Won't boot after system update "invalid bootloader file"

SDK Get Help

@Mr.Mitternacht Looks like your device has recovery firmware available, so try this:

  • Boot the device and let it reach the "your playdate has crashed" screen
  • Hold down A + B + Menu + Lock for a little over 5 seconds
  • After it reboots, release A + B but keep holding Menu + Lock to confirm entering recovery mode

This will get you back to 1.11.1 and hopefully you should be able to download and install the 1.12.2 update as normal from there. Your games and save data should remain intact. Let me know how it goes!
