HI, I flashed a new image ,6.2 and wooshbuild infinity to one of these boxes yesterday. The problems I had were caused by not waiting long enough between key presses on the remote, or not giving the box a long time to respond . They are very slow and I thought that the box had froze and I kept restarting again. My box took 2mins 30 secs to read a usb stick and FLSH was shown for about 20 mins ,with the box giving no indication it was doing anything. Flashing online is still very slow and takes as long.
