Not using it as a daily driver yet, but I was able to install onto a XQ-DC72 successfully. Needed to edit the flash-config.sh in the installer to accept XQ-DC72 as a VALID_PRODUCTS, and update the MD5s to allow that install to proceed (can provide literal steps, if helpful) 
For anyone that’s interested, in Australia, it seems that VoLTE doesn’t work with Telstra (tried via Boost), but does seem to work with Optus
