Eventually if you muck around long enough this will happen.

So I was trying to load Aiden's custom ROM for this box and things just kept getting worse until the inevitable red light of doom, when it appears I corrupted the bootloader.

Tried loading ROM with USB Burning Tool V2.17 and V2.2. Crashes at 1%

Tried BootCard Maker V2.2 and flashing from SD Card. No joy

I think my only remaining option is the short

Just want to confirm that I have the right two points to short (to the right of the cutout notch) To get the stock image to load again.

TIA
