like, it was displaying "erase flash block 2072" with the number at the end increasing slowly, and i immediately pattern matched it to "device in weird state, shrug and restart it" and hit the power button before registering what "erase flash block" meant

okay yeah apparently this is just the firmware updater and it decided to jump to it for no particular reason
scrolling through `strings elegoo_lcd.bin |less` while i wait for stuff, as one does, and found this neat bit
wait, is this firmware just a hacked up *Marlin*?
