My DR750S started telling me it was reformatting and to not disconnect the power. Did this for many days so I reformatted the SD card, loaded the latest firmware, reinserted into the camera. The camera then told me ' Upgrade in process, do not power off". It said this twice and then nothing. The white LED at the fornt of the camera is slowly flashing but thats all. I've reformatted and reloaded the card a second time but now the white LED just flashes. No voice messages and no other LED's light up.
Any ideas how to reset the camera or try something else.
