I tried to install CM12.1 based Sailfish OS on my Nexus 5 but I am stuck in bootloop. I can see the Google logo only. I have latest TWRP 3.2.3 and I also tried with 3.1.0 and 3.0.2 but same result. I can't install the pure CM12.1 Android either. However, I am able to install CM13 based Sailfish OS just fine with latest TWRP. Any idea how I could install CM12.1 Sailfish OS?
