IPTV STRONG PRO CAN BE FUN FOR ANYONE

I made use of your application to up grade my strong 4669x and soon after booting I observed lock within the display.I attempted to unlock it by dialing 0000 and I afterwards saw the decoder was frozen Even though the lock wasn't there and the many channels was vanished.The decoder is now frozen.What should really I do?New strong models like 4950,
