Cannot update to fw 20210715 (Phenom)

Not sure what I’m doing wrong; following instructions on

Current version is 4.3.4_lcdh

I have loaded all firmware onto usb at root and am attempting to “print” the “update.LCD” file per instructions, but get error message on machine: “Unknown file format!”

hi, it should be that the firmware is not in the root directory. When updating the firmware, it is best not to have other files in the USB flash drive. If you still can’t update the firmware, please contact us by email so that the peopoly technical team can help you in time.

Solution: turns out my apple machine was generating some different files with similar names, and trying to update with these was causing failures.
