i3 Origional firmware upgrade failed
I tried to file this with Prusa support, but that web form isn't actually working, the submit button does nothing.
So now not sure if I've bricked the controller board, certainly appears that way. So how do I get this 3D printer back on the road? Was flashing with PrusaSlicer-2.9.4 the firmware file prusa3d_fw_3_14_1_MK3.zip
Thanks for any help

The best way to contact support is via chat.
But you may find that one of these pages, probably the first, will help:
