Reverted back to 19.07.7 successfully.

I have created a devicepage and added this information.

Would be great if you could upload a picture of the PCB and the serial port.

J4 is the serial port. PCB photo failed to upload (3.3MB/4MB limit).

Does the same happen when you shrink the image?

I can shrink the image. Charging the old camera's flat lithium battery, instead of cellphone photo.

Ifranview shrunk the image to 517KB.
