I updated my Olympus Zuiko ED 70-300 mm 1:4,0-5,6 lens from 1.3 to 1.4 with my OM-D EM-1 + MFT 2 FT adapter over OM Workspace software. After the update the lens no longer works and not detect. I think the firmware is bricked...

Is there any way to fix the firmware?

Maybe with a Panasonic body und the firmware file?

Maybe direct over the lens pins with an Arduino?

Can anyone with a simular problem help me please?
