My access to internet radios was no more working since a few days so i did the firmware update to 3.05 to solve the problem.
It was not my first update of my 500X and i never had problems in the past.
All seems to wok ok. I had the "install completed" message on TV screen. Then nothing happen. The 500X kept the start picture (blue white logo) on screen and now i can do nothing. All remote keys refuse to work and i can t power of the 500X.
After unplug the DC cable if i power on my 500X, it shows same picture. I did try new install (using other USB key) and all was the same.
Thanks for your help and advices
