As I was trying to get the hang of this new to me, receiver, disaster has struck. Boot files may have been corrupted. The box does not start up at all. At start up, it displays... checking... checking... and does not go any further than that. The remote control functions or commands are not working. Re-flashed it using TM-500-600-500S boot load-3-1-11 via null modem but nothing happened. Can no longer be able to connect it to the net but the null modem is working. Is there any firmware or boot loader out there to restore the life of this receiver? Give me a shout. Thanx
