Question How to diagnose brick?

I got my hands on a "broken" KV that does not boot but only displays a battery with an "!".

Connected to a PC it shows up as "SE Blank MEGREZ" and no drive. I want to fix it.
To find out what is broken I want to boot into diagnostic mode.
I tried MfgTool from KindleSelectBoot.zip but it does not detect the KV. According to some post here the MfgTool in KindleSelectBoot is too old for the KV. So I searched for a newer version but only found uuu.
uuu detects the KV:
Code:
Connected Known USB Devices
        Path     Chip    Pro     Vid     Pid     BcdVersion
        ==================================================
        1:3      MX6SL   SDP:    0x15A2 0x0063   0x0001
How can I boot into diagnostics mode without MfgTool? And does the diagnostics mode help to figure out why the KV does not work? Any suggestion for what I could try?
My goal is a working KV, jailbreaking is not my goal.

I have orderd a USB->TTL stick but it will not arrive for another month.

Thank you for your help
