Some models seem to have the firmware installed already. There is a chance that different region might used different firmware.It is best for you to wait for the final to officially be released. The firmware they have emailed me is not officially released yet , I rather not share it with anyone in case that it might not be for the right region.
It has been incredibly hard for me to go back to other gears ever since I spend more time with ckr10.
I am still confused on whether ckr9LTD is going to offer any substantial upgrade from ckr10. Over all ckr10 with the right tip is one of the greatest purchases I have made this year.
