hi PosixCompatible,

thanks for the detailed instruction. sadly it didn't show any light :(.

I'm including the output from cmd below:

; nothing happened on the phone, so I skipped the turning off command

I'm guessing something might have accidentally deleted my parameter folder for the light.

any way to find this or fix it?

thanks a lot!
