I was a bit amazed today when my I1 asked to do an "upgrade" for the battery. Well I downloaded the bin file again to the empty card and made the update like I did after the last firmware came up in late May. The battery reacts like always, green strobo etc. It took about 5 minutes and after I check the txt file it says: ========== 2014.01.01 00:00:10 unsynchronized ====== Packet: WM610_FW_V01.02.01.06.bin Upgrading ... What does this mean? No fail, no success, no abort but "unsynchronized". I could not find in the manual nor the video tutorial what this mean. But when I started the I1 again, then it did not claim any update nor upgrade any more. Is this familiar to anyone?
