The problems are probably caused by this different hardware. I don't know why you have a different chipset in this equipment... I've never seen anything like this in this Asus/LG model...
The only hope is the modernized DosFlash V2.0 from this topic = you need a computer with Windows XP-32 bit / 7-32 bit.
DosFlash V2.0 patched to support BH16NS40/BH16NS55 drives
DosFlash V2.0

But first I would backup the firmware also DosFlashV2.0 -
I don't know how possible it is to install the VinPower firmware correctly in this case !!!!!!!!!!!!!!!!!!!!
