2, make sure the system starts correctly without rx480
3. turn off the system, insert "dead" rx480, connect 1 and 8 pins on its bios somehow (soldering, paperclip or whatever, I used a paperclip), power on
4. if the system turns on, go to windows or dos, disconnect 1 and 8 pins on rx480 bios, check if "atiflash -i" sees the card then reflash it with proper bios file. Otherwise check if 1 and 8 are properly connected at startup.

I just registered a new account to THANK YOU, THANK YOU & THANK YOU
for your information.
I brick my Sapphire RX550 2GB PULSE by flashing a wrong VBIOS (RX560) to test, and it is brick, the card seems completely disappeared, no matter I use DOS, Windows or Linux. ATIWinflash -i said "Adapter not found".
I found your post and try to short pin 1 & 8, until windows 7 start,
windows try to search for a new device,
I remove the "1+8 pin short",
I use ATIWinflash to flash the original backup ROM,
and the card is alive
For those not sure which is 1& 8,
the pin with white dot / arrow is 1, and count clockwise, last one is 8, at the other end,
here is the picture, showing which 2 pins to short:
