Disk not detected with UEFI full rom firmware on TAEKO

I have an ideapad flex 5i chromebook (boardname taeko), I think it has an 128GB ssd. After i flash the full rom firmware the disk is not detected anywhere. I’m happy to provide any more debug or device info if needed.
Here are some screenshots for reference

kali live usb running in RW_LEGACY firmware, looks like the disk is detected

After flashing the full rom firmware i can’t detect the disk anywhere.


Thanks for the help.

cbmem log please

I am having the exact same problem, did you find a solution? @MrChromebox @85_czt

no, I did not

Can I help in any way?

could there be a solution if I tweak with the custom secure boot settings?

has nothing to do with secure boot

then, what does it have to do with?

This failure is related to Alderlake-N sometimes not detecting eMMc drive @MrChromebox ?
