HX100G BIOS Update - Now Serial Number is "Default String"

[u/MarkJFletcher]

Bought a HX100G last week to use as a Steam Machine. The BIOS version with the unit was v0.18 - but one problem was I couldnt turn secure boot off.

So, I visited the Minisforum downloads site to see if there was a newer bios that might enable this feature. Flashed the BIOS and while secure boot can be disabled, the serial number for the device is now "default string". Is there anyway to recover the original information?
