Bricked my motherboard in BIOS update

TD;LR I updated the BIOS on my MSI b350 gaming pro, and got no video output or keyboard LEDS afterwards.

I went to go update my BIOS from the version a year ago, however when updating, it just does nothing. No debug LED lights, fans spin and motherboard LEDS go on but no video output. Pretty sure I have a corrupted BIOS, but not sure. It could possibly be that I had the BIOS file in a sub-folder of a Ubuntu live boot drive, not in an empty USB, but not sure. Should I RMA, buy a replacement BIOS chip and re solder, or do something else? Is my motherboard permanently bricked?

Kill power, pull the plug, hit / hold the reset cmos button if there is one, pull the cmos battery. Let it sit a while and see if you get anything. If not you'll probably have to replace stuff unless MSI has a better idea for you.

Since motherboards in the recent years have an absurd number of layers to the PCB you will more than likely not be able to get a new BIOS chip. If you want a challenge you can try, but I wouldn't recommend it. There are some tools that you can use like this to reflash a BIOS that isn't getting a signal, but they can be iffy as well and they might not work given we aren't entirely sure the problem here.

The easiest method is going to be is try to RMA it. Since it is a B350 board it is more than likely over a year old, so it might not be covered under warranty. I would still give it a shot and if you can't get an RMA, then snag a new board off your favorite site.

I was conside ruograding to x370 anyways, however if can’t get any recovery options to work that will likely be what I’m doing. I also did not take PCB layers into mind with a replacement chip. I would expect 8-12 layers, which might be beyond my abilities. Also on a side note, I cut off the barcode on the box for a MIR of $20, is my motherboard still eligible for warranty without the label?

If you explain that it might be. They should have that on file and associated with your card. Do you need the extra features of the X series over the B series boards? If not then you can probably get a B board cheaper.
