I have the P3A. I've updated firmware successfully before. This time,not as lucky. Did everything properly on the sd card. The only exception I noticed is that the "how to install firmware " file is for 1.2 which also wants me to upgrade the remote controller. I did that last week successfully. Now when I insert the sd card into the camera slot and power on the P3 the camera light flashes green for about 5 seconds then goes to solid green. No update is in progress as far as I can tell and there is no txt file on the card. Any insight would be appreciated.
