I have recently upgraded my modem to the ARRIS SB8200 and the firmware will not update.
This happens every time it tries to update.
Hardware Version 6
Current Firmware: AB01.01.009.32.01_122319_183.0A.NSH
It indicates that the firmware you are getting is for a different model of 8200. I would verify that you actually have an SB8200. If you purchased a used or refurbished 8200 and it was re-flashed to the original code, it's ruined and won't be able to be updated, you will need to return it.
I have purchased another one, new out of the box and the same thing is happening. The only difference with this modem is that the out of box firmware is newer but it still won’t be update :/ …

What is the current COX provisioned firmware for this modem?
If you have a account over on DSLReports, you may want to take this subject over there. A thread very similar to this was made over there and resolved by Odog, a Cox employee there.
