No it doesn’t work.
I tried that expreminent:
# save current ROM image to file
afuefix64.efi original-rom.bin /O
# try to re-flash by original rom-image
afuefix64.efi original-rom.bin /P /N /R /X /CAPSULE
And it well done! After reboot it autorunned flashing procedure in BIOS menu that successfuly ended.
Conclusion: Method of flashing and set of params by afuefix64.efi is probably right, but problem with MicroPC.4.13.bin firmware (may be it released for older MicroPC devices? I bought my recently…)
Fortune telling without clarification.
