until i get to open my own arc best best i can suggest is click on this link within your own arc browser look down the first post till you see the series of flash players build numbers and click on 11_11_1_115_34 and install it. this is the most recent update for flash and is running fine on my onex. this was an ota update via the google playstore. hope it helps
