I've tired to download and flash this image via usb but it doesn't flash, other releases may also be affected.

The problem is the fastboot.bin file, the one included in the zip is 382,464

If I replace this both on the root and in the h9 folder to an older one that is size 787,968 the box then flashes.

Now once the box is flashed and I try to flash a newer image online say version 20190703 it goes through the process of downloading and unzipping but it doesn't flash and an error saying "image to install is invalid"

This may be because the online download image also has a non working fastboot.bin??

I'm not entirely sure but can both these issues be fixed?
