Hello all, I am helping my disabled Vetarin fix his Ph3 standard. It flys fine, has telemetry, but no live video signal. The software version is 1.4 and I have figured out that version had a bug that would cause the video feed to fail. I would like to roll back the firmware to an earlier version. I dont seem to be able to find a version to roll back too? Is there a list or link somewhere still? I tried the latest version, but the bin file wont initiate the upgrade. Is it possible for me to connect direct to the main controller usb and not the camera usb to upgrade firmware? I know a bunch of questions and sadly he never did firmware updates. I am unable to recognize the SD card using the usb on the camera to my computer. I am also open to any and all ideas. I know it is an old bird, I was just hoping to get him going on it.
