For creating backup of bios you can use attached utility. Extract attached archive directly on the Desktop and run utility as Administrator (right click mouse, choice "Run as Administrator"). Utility will create archive "results" directly on the Desktop. Post here this archive "results", or upload it into any fileserver and send me the link.

Disregard, I figured out the 104 error on my own. 

 

For those getting the Error 104, you will have 2 devices mentioned in the error output. All you need to do is go into the fparts.txt file for the two corresponding device rows and make the chip erase command match for both devices. Try 0x60 or Oxc7 for both affected rows. I changed both affected rows to 0x60 in my case and the flash process worked from there while also running prr.exe first to get past an additional error 28. I'm now running svl7's bios and can put in my own WLAN cards
