ESC ORI 4 in 1 - Only two motors spin ok out of 4

#1

ESC ORI 4 in 1 = Only two motors spin ok out of 4. I checked it in BLhelix and the 4th ESC has some strange chars in it ŸŸŸŸŸŸŸŸŸŸŸŸŸŸ. Only two motors spin normally and the other two spin with stuttering until they stop completely . I swapped the motors to check if they’re faulty but motors work great. Any ideas? Do I have to upgrade de firmware on the ORI? I’m currently running 16.43.

Cheers

Check the signal wires aren’t shorting. I had similar issue recently and that was problem

I’ve tried already, it did not help. I connected the ESC to the BLheli Suite and the 4th ESC is unknown. I’ve tried to upgrade it to the latest but is always skipping the 4th ESC. Do you think it’s still shorting?
