No, a BIOS programmer cannot unbrick a motherboard.

It fits on either side of the chip that connects to the pins. Are you certain it hasn't been permanently damaged? Did you verify it thoroughly?
You're referring to those awkward bios clips that seldom function? You'd rather skip them. Instead, try a Dupont female jumper with the SPI header on the motherboard, positioned above the PCIE X1 slot on the B450M Pro4. It's a 9-pin header—here are some pin configurations for SPI headers. It seems your board might be using the ASUS layout because the key pin aligns with the same spot as the ASUS board (diagonally opposite pin 1 marked by a grey right angle on the B450M Pro4). For the Ch341A side, check the underside of the board for the pinouts. Basically, it's just a tricky puzzle game—connect to the WPN pin on the SPI header, find that pin on the bios programmer, attach your jumper there, then match it with the corresponding pin on the SPI header of the motherboard.
The clip seems to connect all four pins on each side at once, rather than touching them individually. The motherboard isn’t damaged, but you might want a way to restore it if it gets bricked during future BIOS updates. Your comment was appreciated.
