Hello,

I have Veriton N4640G with BIOS version R01-B1. I tried few times to upgrade it to R02-A4 version, but during upgrade process it gave me error "ROM File size does not match existing BIOS size". How to fix it?

    You are not supposed to upgrade to R02-A4, as it is for N4640G with the next gen CPU. R01 BIOSes can't be upgraded to R02 and vise versa.
    Always post the following characterisitcs of the device:
    -Model number
    -Part number(not required, but helpful)
    -CPU
    -GPU
    -Operating system

    Helios 300 and Nitro 5 users DO NOT update the BIOS to version 1.22 if you don't want the keyboard's backlight to turn off after 30 seconds even when the device is plugged in.
