I'm an idiot, I didn't do the reboot marked IMPORTANT before trying to flash the UEFI firmware.  I tried to be so careful checking everything character by character and still screwed up royally.

Now I'm afraid to go any further, since I fear I probably screwed up the firmware and will be unable to successfully reboot the Chromebook to continue the flash.

I also probably messed up even more when I retried doing the flash and let the script backup the firmware a second time.  I didn't change the backup file name and probably overwrote the first good firmware backup file with a second file with garbage in it.

Can you please give me a hint on how to best proceed?

Thank you,

Dave

Subject: Full UEFI firmware install error on AKEMI
 
I received the following errors when attempting to install full UEFI firmware.  The statements about rebooting conflict with each other too.  The first says that a reboot can be done, the second says do not reboot in CAPS.

I believe I followed the instructions correctly, all of the checks matched the instructions.

Thank you in advance for help with what to do next.  Please note that I am not including the many lines that preceded the error lines below.

Good, writing to the flash chip apparently didn't do anything.
