Hi Les, The way to update your cam is:
1)Download the latest firmware version - today from the mini0806 web site location is:
http://www.mini0806.com/firmware/0806firmware-160507.zip
2) Inside the downloaded zip file is the file; Firmware.bin. Copy this file to the root of the microSD card and insert the card into a SWITCHED OFF camera.
3) Switch on the camera and (it should) power up and detect the firmware.bin file on the SD card and ask you if you want to update the camera.
4)Using the up / down buttons highlight the YES option and press the middle OK button. The camera SHOULD update itself and power down.
5) Ensure the camera is switched off and remove the SD card. Use your PC to delete the firmware.bin file BEFORE re-inserting it back in the camera - otherwise it will continually ask if you want to update.
You should be ok now but if you are not then repeat process but FIRSTLY REFORMAT THE SD CARD IN THE CAMERA - just in case it is a file corruption issue as some SD cards can give problems - I have used many different makes and sizes until I have one that works well - the more expensive the SD card the more reliable it seems.
