Just got a brand new gma3 onPC 2Port Node 2k out of a box. It has version 126.96.36.199 in it and I am trying to update to 188.8.131.52 following these orders: https://help2.malighting.com/Page/grandMA3/update_xports/en/1.1
However when I turn on the node with the usb, it the screen just goes full white, not prompting anything about the update. On a smaller flashdrive of 1 GB it boots normally after a while, on larger (32GB) it just stays full white.
So far I've tried with different drives and formatting them again (FAT32 as it is told) and copying the files and 2 directories both from mac OS and PC but with no success.
Does this sound familiar? Is there any other way to update the software?
