You may use this APC Resource Link to download the latest 7.2.0 Symmetra firmware release:
If you still require v7.1.2 firmware you’ll need to contact APC Technical Support to obtain the same if available to them.

Hello, the product page you provided is missing firmware for the 3 phase symmetra. this is my whole issue. only single phase is listed under firmware and the file would have SY3P in it.

It appears APC has removed all previous links / reference to the 3 phase firmware. Using the NMC Support links also goes to a dead link.
Suggest you contact APC Technical Support to obtain the needed firmware. Please do share the same as I’m sure it will help the next person asking the same.
