Motorola SB6120/SB6121 - Firmware / CVC

After a recent RFGW install, we have a handful of Motorola SB6120/SB6121s that won't bond to wideband channels. We know it's a firmware problem because we have other modems on newer firmware that are working.

Would anyone be able to help me find firmware and the CVC for these?
