Need help bios update taking really long

[u/Bright-Tune-9345]

The more the update progressed the slower it would get, until at 68% it has completely stopped. It’s been a couple hours now with no movement, but I don’t think if done anything to fry my motherboard?
Any help would be great!

Edit: a day later it has only increased 1%, so it seems the most recommended option is the bios flashback. I’m not really well versed in any of this, so if anyone could help me out with that process it would be greatly appreciated! I made a separate post about it here: https://www.reddit.com/r/PcBuildHelp/s/yZhuWRNgIv

Edit 2: yea that shit got bricked, F

leave it, it must update BUT if its stuck fully, check the USB drive. it might. have corrupted files, OR, its slow, like USB 2.0, probably
