I'm using darkera13's 6.0.1 s7 edge port. Works very well on my sprint note 3. Very minor bugs. It did break 3g/lte. Manually setting the APN used to work, and can work for other generic note 3 roms, but in this case, it wouldn't work anymore. It would either work shortly before automatically choosing another apn, or not work at all. Then I found this great app called mvnoslayer. It sets the apn to sprint or any of its mvno's(i'm on ringplus). Even then, I only connected at 3G. I had to edit the apns-conf.xml from the app myself and delete every reference to the number "13" from it (13 refers to 3g and 14 refers to lte). In the end, it connects at LTE(4G icon), and only goes to 3G when LTE is not available.
Here's the link to mvnobuzbee, a modified mvnoslayer, and will still need to edit out the 13, or you'll be stuck at 3G
