There is no higher firmware than the 8.0.2 that's already installed. I tried to upgrade to 8.0.3 beta, but the device says it's not a valid firmware and automatically aborted the installation. That beta version is only hosted on a non-official site so it's not sure if it's fake. I'll sell my R10 asap.
man is that bad, why don't u try to erase all your songs, and try adding only few albums and see what happens, maybe its the sdcard, or something. I had high hopes for the hdp but not anymore after reading your experience
