Maximum Hero IX - Unable to update BIOS

Hi,

I have a Maximus Hero IX (Revision 1.xx), Intel i7 7700k, 32Gb RAM. My BIOS is version 0505.

I have tried upgrading to the latest BIOS (1301) by using the EZE3 tool within the BIOS itself and via the BIOS flashback option. While it seems to update, my PC won't then boot afterwards. It comes on for about 10-20 seconds, no display output and then switches itself off.

I have also tried BIOS version 1203 - same issue, but BIOS 0701 works ok - any ideas?

When it shuts itself down the QCode goes through 60-61, then 00 and then it just goes off

So, I've tried updating one version at a time, and it's ok until I get to 1009. Once that is applied, my PC keeps shutting itself down during boot.

are you doing it assembled or stripped down?*
