Upload & Sell: On
I upgraded the first day as well, with no apparent issues. The camera has been fine. I put in a fresh battery yesterday, and the LCD displays "battery not recognized, do you want to continue?". When I hit yes, everything functions normally, but there is no battery charge or life indicator on the top LCD display.
Initially I thought it was because a 3rd party battery, but when I replaced that with a canon battery, the issue continued.
Maybe I'll reload the firmware tomorrow.
