Never heard of the bios trick, but if you flashed the bios and then it won't turn on it's probably the bios that's the issue. Older rog laptops have issues flashing the bios from an NTFS partition. I don't know if this is what you did, but if you did it's not booting because of the corrupted bios.
If you didn't flash the bios then obviously it's not the problem.
If I were you I would disassemble the laptop, take out the board and see if you damaged anything. Also try to bench test it on a glass or wood table, just make sure the keyboard/palmrest doesn't touch the board when you're testing it.
Let us know what you find.
