ISP SuddenLink Won't Update Firmware C6300 AC1750

Just for fun, thought I'd chime in with a different but equally frustrating issue with this whole Suddenlink firmware business.

I have a CM600 running 1.01.14 that was on Spectrum.  It was purchased brand new a year and a half ago and always online with no issues.  I moved an hour away where only Suddenlink is offered and the CM600 wouldn't connect to their network.  They could see it but couldn't get it online.  They told me to call Netgear (sound familiar?).

Netgear said that the CM600 firmware for Suddenlink needs to be 1.01.12.  I asked Netgear to load it they said they couldn't.  I asked how I can do it and they said I can't.  We conference called into Suddenlink customer support and got "we can't touch customer's personal modems sir, it's encrypted data"(!!!).  

Long story short, I had to buy a new $100 modem to get stock firmware.  Bought the CM700 and out of the box it went on their network no problem.  I pity everyone who switches from Spectrum to Suddenlink with their own personal modems...
