@mutahharbashir lineage-18.1-20210713-UNOFFICIAL-treble_arm64_bvS is booting fine but has the same 4G/LTE Volte issues. Reflashing led to the issue with storage again not being accessible to the camera app. Booting and running faster than 16.
I was not able to flash Resurrection Remix RR-P-v7.0.2-20200202-ravel-Unofficial. The device check during install throws an error mentioning the device is "charlotte" and not "ravel". How did you manage to install?
