Broken DL mode, No recovery, Not booting

hey there.
I'm in a situation where i cant boot the phone beyond the LG logo and my download mode is broken because of the bootstack that messes up download mode.
Is there anyway for me to fix this or is my phone now officially dead? I have access to mac and linux (windows if really necessary).

I'm sure I've seen some ask for help in a similar situation, but I've not been able to find the thread.

Thanks
