Is that the miner with a Beaglebone board? it should have an SD card slot inside what I heard before is that you need to reimage the Beaglebone board in order to do that you will need the SD card firmware from Bitmain which is still available on their download page.
Here's the direct link
https://file12.bitmain.com/shop-product/firmware/Tools%20and%20Instructions%20to%20Image%20SD%20card.zipThe tools and the firmware is already on that file just extract them you will need an SD card reader to burn the img file to your SD card use the diskimager to burn it to your SD card.
You can follow the guide here
