I am currently running a stock room for the Moto g7 power commonly refered to as the ocean model. I have an unlocked bootloader a rooted firmware and I am running a unofficial twrp custom recovery. I downloaded the official lineage os .zip file and when I flashed it using twrp it went through cleanly even getting past the zip verification but once the installation is done it still says that there is no OS on the phone. I also wiped my dalvick cache and system partitions before flashing this rom. Any solutions?
