Good morning all. I have reflashed my H7S box doing the couch upgrade. It worked fine flashing openvix-5.3.039.release-zgemmah7. The box completed the flash and auto rebooted. But - the box now stops during boot showing "49" on the front panel. It is entirely unresponsive and all i can do is restart it on the rear button. Flashing from USB does not work. The perocedure to power down, put the USB stick in, power on pressing the front under flap button doesn't work. The box simply reboots and stops showing 49 on the front panel. I fear I now have a bricked H7S. What can I do now please?

Thanks.
