After 2 years I am finally exploring my Priva Px-5s. I tried to download the firmware update . Right now I am at 1.00 and I believe I want to update to 1.11. I tried 3 different brand new USB drives. I formatted each one. I placed the downloaded file into Music data on my PC.& then loaded onto my thumb drive. The message I continue to get is No -File ---No -Media. So i am still at 1.00. I tried placing the thumb drive in & powering up. Is there something else I can try? I am able to do other things with the thumb drive like audio files. Thank you .
