Hi, I updated the bios on a replacement board which I fitted in my Yoga 900 13ISK. The replacement board was originally: Bios: C6CN35WW and EC: C6EC32WW. I ran the bios update and it is now C6CN39WW, but the EC version remains stuck at C6EC32WW. I have since tried everything to get these to sync, including updating the platform.ini, attempting to install older bios versions, but after upgrading to C6CN39WW, the only message I get after the machine reboots to try to flash the bios is "InsydeH20 - Secure Flash\n Error: Firmware update failed !! \n Please press any key to reset system".
1/ How to update the bios to get the EC to be correct?
2/ How to flash the serial and MTM?
3/ Could this be the reason an SSD is not detected? I have tried with an Intel SSDSCKKF256H6, but the bios doesn't see it. It is a 16GB US board which I believe should take SATA SSDs. I'm slightly worried that the different EC version and missing serial/MTM info could somehow be causing the machine to not see this SDD (or any other which is my worst fear!!)
4 Is there a hardware maintenance diskette for this model? (or similar)
Thank you all

What makes you think the EC version should match the BIOS version? They are not one-to-one.
Maintenance utilities are normally available to dealers and warranty servicers.
