Yoga 900 - BIOS and EC version discrepancy and INVALID serial / MTM info

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".

So questions:

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.

ok, my experience with Lenovos to date has shown them to be the same. I didn't know they could happily be different. It's strange I can't backflash though. thanks.
