[Moto G5S  Questions & Answers] Andrew Reeson:
Yes, Moto drivers are installed

Using the fastboot method I receive the error: "error: cannot load 'gpt.bin': No such file or directory"

gpt.bin is definitely in the folder, but fastboot can't find it

Using the .bat method I get much further before I receive: "(bootloader) Image size exeeded partition limits

(bootloader) Preflash validation failed"

Here is everything from that process:
