loaded firmware 1.2.6 today. Got a series of tones after 12-13 minutes so I thought it was complete. I was wrong. .txt message indicated "synchronizing" thus I infer it was not complete. checked a few youtube posts and a few guys warned that you'd get a few more warbles, whistles, bleeps etc. on this download. Sooo, I figured okay load it again. Now getting a steady loud beep beep unlike any of the previous firmware updates and camera setting cocked down and left and acting kinda twitchy. Quietly, (can be heard just beneath the louder beeping) I can hear a sound like the normal cadence of firmware being updated, unfortunately I noticed the battery is low so I chickened out and de-energized to recharge the battery. Will try again this evening with full battery. Anyone else done this? Secured system before firmware was complete?
