My Lenovo Z410 came with v37 BIOS dated 2013.
I went to Lenovo website and downloaded and ran 8DCN40WW.exe
Instead of taking normal time to flash, Windows started rebooting after only a couple sec.
No bootup. No beep. No Lenovo logo. Power light comes on. Blank screen (no backlight).
After 50+ bootup attempts I sometimes get the blue error message at bootup:
InsydeH20 invalid firmware image.
After changing RAM positions, and trying the Lenovo "rescue" bootup button, I got a bootup.
CPU-Z still shows the BIOS is V37 (ie it didn't flash). I know I have Secure Boot enabled.
So, to fix this I believe I need to force flash the old v37 BIOS image.

So, after some research, I see there are only 2 (reasonable) options:
Try flashing from DOS using USB flash drive:
De-solder BIOS chip and reprogram:

You did not call Technical Support it seems and if you're out of warranty. This should have been updated well within the first year. I always check for update within the first week or two of any new machine and onwards as changes are released.
Updating the bios is a propriotory process developed by each manufactures tools. Generic methods may not work.
