Follow the directions from any 5.x model -
only changes are the version number of the firmware being flashed that are model specific.
But you will most likely not need to do that (re-flash to a blank eMMC - there is firmware in there already, that is running).
It should be fixable, but get the serial port interface working before you decide HOW you are going to fix it or WHAT it is you are going to fix.
The step you should skip for now is the predefining what repairs the device needs before you have seen the messages being produced during its start up.
PS: Leave device on wall charger while thinking, planning, getting ready.
A few days on the wall charger might fix it.
