Hello all,
On eBay I bought a motherboard for my Thinkpad Yoga 260 (the old one died), but it turned out to be locked. I tried the trick with shorting pins 5 and 6 of the Winbond BIOS eeprom, but I never got it to work. I then reflashed the BIOS chip with the old, original image and with one I bought on the I'net. No luck. Tried shorting pins again, but it didn't work.
Now when booting, on screen I only get two small icons next to a lock icon plus 2 error messages:
    0271: real time clock error
    0183: Bad CRC of security settings in EFI variable.
I'm out of options. Does anyone have an idea?

Thanks Dudu2002. All is up and running again.
It was quite a job, but you really helped me out!
