Edl-1 inoperative after V3 update

Can’t seem to get my Edl-1 operational again after updating my black to V3. Ive tried multiple different SD cards (formatted fat32) that are listed under excellent in the manual. Its been updated to v1.21 a while ago. Green light stays on, blue light flashes. Shows time/date setting successful. Does the green wire for tx at edl need to be connected to rx at the ecu w/V3? Never connected that with V2. Edl-1 is selected for Serial com.

Version 3.049 27-05-2025 and later –>>>
