No display/ No Signal after switching display settings in BIOS. Help!?

HP dv7 6b78us Entertainment
Microsoft Windows 10 (64-bit)

Long story short I flashed a custom BIOS (which worked fine until my genius idea). I changed something in the display settings (in BIOS) and when I reboot the notebook all I get is the wifi key (F12) lighting up along with the power button and the outline of the trackpad, no capslock blink or anything. I've tried recovery via usb with no results. After searching online for MONTHS it's like no one else even has this model. is 017FC.bin the right filename? Any suggestions?

Have you tried a hard reset to see if BIOS defaults will be reset? Not sure if it will even work with a custom flash but only thing I can think to try.

 

Disconnect all external devices first.

1-remove power cord and battery

2-press power button for 30 seconds

3-reinstall only power cord for first startup.

4-power on

You may be able to force BIOS to load Default settings if you remove the RTC battery on motherboard for about 5 minutes.

Probably should've mentioned it, but I've left it out for days at a time with no luck. If you're familiar with flashing the original bios, I do have a question: is 017FC.bin the correct bios file to flash or is there another/another filename out there somewhere? I got the 3 in 1 diagnostics usb file and inside was a file called BIOSCopy.csv, which named all the different models, but i combed the list and didn't find my particular model or system board id (1800, apparently) anywhere.

Sorry, I do not have a lot of knowledge as far as flashing manually. Only from reading many of the posts on here I do know that it is not easy and you need  .bin and a signature file.
