Hitron Modem firmware

I have a Hitron CODA56 on a Next-Gen mid-split node. My upstream power is perfect at 43.7 dBmV, but my upload is stuck at 70 Mbps because the OFDMA channel is showing 'Disabled' in my modem log. Can you completely de-provision my modem from my account and re-provision it with the correct Next-Gen Gigabit boot file?
