Strange…with all these files.
You have here another one and read lfb6 content that will lead you to a “quick” guide showing you what kind of operations we need to perform, for trying to rebuild a current system dump with original update files, this is what you ask previously.
You will notice the EC part and a 2nd IC mention… and as lfb6 states, i also concur that its very unlikely that they got corrupted by a failed bios update.
That’s it from me regarding your issue, all the best, good luck.
