Hi, I am now the proud owner of a Pentax K100d - which I absolutely love!!! Download Profiles On Iphone more. That is except 1 thing! - I can't seem to update the firmware!!! V 1.0 is on the camera at the minute and I have downloaded the new firmware from Pentax's website, but when I put the.bin file on the root of the SD card and start the camera holding the menu button, I only see the firmware version on the screen and the camera won't update. I have tried the bin file in several different locations with 2 different cards. Any one any idea what could be wrong?
