Hi everyone, My MSI PRO B660M-A DDR4 motherboard got bricked after a power cut during a BIOS update. Local repair technicians are asking around 1/3 the price of the motherboard just to fix it, so I'm deciding to try repairing it myself. I ordered a CH341A programmer along with a 1.8V adapter because the BIOS chip on this board is an MXIC MX25U25673G. I do NOT have a WSON8 probe because those are too expensive for me right now, and I also have zero experience with desoldering SMD chips, so removing the BIOS chip is basically out of the question. I heard that the JTPM1 header on MSI boards may provide direct access to the BIOS SPI lines, and some people supposedly flash the BIOS through those pins using jumper wires. So I wanted to ask where each of those pin connect to which in CH341A. Are there any risk of damaging the board if I wire it wrong? I don’t really have access to other proper electronics repair tools, so I’m trying to learn and do this carefully. If anyone could show an example diagram or advice for this exact board, I would seriously appreciate the help.
