Reply To: X2 pro : SD card mounts and unmounts endlessly

Sometimes when I have experienced this type of problem, it is not always software/hardware that is at fault, but physics.

Try the following:

Rub the card contacts very gently with a pencil rubber/eraser or you can use a spirit cleaner like the type for cleaning glasses, surgical wipes work as well. Don’t use any wipes containing soap or other residue forming solutions. When installing the card, make sure you do not touch any of the contacts on the card.

Use a can of compressed air and blow this into the Card slot. If you simply blow into the hole yourself, you will be putting as much moisture as air inside the device which can lead to corrosion.

What both of these solutions provide is to remove any microscopic dust particles and or oxidization that forms on electrical contacts, through the natural process of having electrical molecules passing through conductive surfaces (see your car battery terminals for an extreme example).
