FX30 firmware for Bell Canada

Wondering what firmware to use for FX30 model 1104086 to connect to Bell Canada network?

Basically there are two questions:

  1. There is CatM firmware release 11 and release 14. Release 11 release notes say that this part number can be upgraded to 11. Release 14 is silent on that topic. So can I use release 14 or do I have to use release 11?

  2. What version of firmware to use- Generic GCF, Generic PTCRB, Sierra, AT&T or Verizon?

Thank you.

I guess you should try “Generic PTCRB” for Bell
