Hi. I managed to flash wrong/damaged bios on my r710. Its dead, only thing that works is dvd drive that actually spins and maybe looking for bios image? Memory stick inserted into any usb port flashes a bit when powering up. I tried all the methods from bios recovery thread but it doesn't seem to work. I don't think any of that fn+b, fn+f, fn+esc work on Samsung R710 At this point I'm really desperate for help. If u have any informations about r series bios recovery please let me know. Thanks.
