820-01987-A - 20V - chime - shuts off - looping

[quasimodo]

Hey guys,

820-01987-A - no liquid damage.

Machine starts, chimes and shuts off directly. Looping.

What to do? Whats wrong here?

Does't it stay on in Recovery menu?

You should try DFU restore, if no important data.

 

[quasimodo]

Nop. Backlight is coming on and then the machine is turning off instantly. DFU at all possible at that state? Data would be nice...

 

[2informaticos]

Check at least if machine is detected in DFU.

 

[quasimodo]

yes, dfu is detected. running revive now.

 

[quasimodo]

revive did go trough, but again...looping...

 

[2informaticos]

Machine turns off completely, or just backlight?

 

[quasimodo]

completely, backlight is turning on

 

[quasimodo]

chimes every reboot...

 

[2informaticos]

If you was able to complete DFU revive, then the data can be recovered in DFU mode.
This can be done only by authorized service, as requires to connect online with Apple server.
After recovery, you can try DFU restore.

 

[quasimodo]

for the machine game over?

 

[2informaticos]

I don't understand...
