GLD-112 corrupted firmware

Trying to update firmware on the 112 to the latest version from V1.42, but every time i go and update it reports that i have a corrupted firmware…

i have tried multiple different USB sticks, I have watched a video and followed the video to a T, I have read the file that is online and followed that to a T and still getting a Corrupted firmware.

is there something i am missing that i dont know about??

Have you tried re-downloading the Firmware?

I have tried downloading it multiple times with multiple types of USB sticks. still no luck.

Have you tried updating to v1.51 first, then going to 1.61?
