I have loaded the openvision image Atevio 7500 on to the box off of usb and it loads and runs. ( https://images.openvision.dedyn.io/7.6/Vision/SH4/) ...there are issues with that image but it loads and runs...so there is still something going with the image here that it will not load past 6...hope you find a solution as I am sure your image solves a lot of problems the other images have. Please let me know if I can help...thank you for all your work!
