If with spi flash memory dump not work you can try do USB upgrade with firmware update provided by Samsung: https://www.samsung.com/levant/tvs/uhd-4k-tv/tu8500-55-inch-crystal-uhd-smart-tv-ua55tu8500uxtw/

But the issue is very strange. Working 5 minutes before fail, normaly the software bug take effect in the starting proccess...
