As I’ve already shared here, your GSI eOS ROM works first class. Thank you Sir!
Your eOS Q-GSI build works equally well on a Xiaomi Redmi Note 6 Pro ‘twolip’ - installed via fastboot.
On first start-up, the SIM card is immediately recognised and the PIN is requested. Incoming and outgoing calls and text messages work as well as surfing via Wi-Fi.
It is worth noting that the installation does not work with ROM ARM64 A - 
as stated in the Device support list (Project Treble) but works with ARM64 A/B -
