LG H811 rooted and bootloader unlocked, I tried to relock the bootloader which succeeded, now when phone starts I get message

Secure booting error
Error 1003

I can still get to download and recovery, do I have to reflash the phone?

You can't reflash. Only emmc or qulacomm 9008 if diagboard(google it) have loader for this phone model.
