Reading the old bios worked but writing failed as verification did not pass.
It would be interesting to see the output from verification.
Writing was going very slowly. I flashed the backup bios immediately which verified fine and everything worked after reboot. I'm guessing something is suspicious about the new bios.
The problem is quite likely that a GPIO pin of some chip is connected to the two write protect pins on the flash chip.
You can run flashrom -V to show their status of them. Please send that output also. (Or combine and run flashrom -V -v so we can get the verify output in one go.)
As the MCP51 flashrom status is marked with a question mark I thought this could be interesting.
Any flashrom failure is interesting! Thanks for the report.
