KeyOne BBB100-1 Hard bricked , Black screen No boot menu or safemode

Alright so customer came with a KeyOne BBB100-1 and the phone is hard bricked, screen is black cant access bootmenu of safemode. White led is blinking when we press power button and blinking a bit faster when we hold power button. amp meter show 0.4 amp but thats all whats working on that phone. It is not recognized at all by computer.
Tried changing battery and port in case its hardware but its not.

I'd try letting it plugged in overnight to ensure battery has juice, then start an autoloader and try any amount of button press combinations to see if the autoloader will catch it.

Welcome to CrackBerry!!!! Post early and post often......

If it's a battery that's barely alive, it might require initially trickle charging with a 0.5 A charger instead of 1+ A charger, like the original charger that came with the KEYone.

tried with a tottaly charged battery from another keyone and it still do the same thing, with sugar or other it still the same
