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...

If the tv works well some minutes, you can do the upgrade procedure in the menu of tv.
