I tried the Pie testing build on the latest StatiXOS ROM. At first it worked fine, then I noticed my phone was not encrypted, so I had to wipe and reinstall the ROM.
Now the phone is FBE-encypted but I tried both builds (statixos and aosip) and my phone gets stuck at the G loading splash screen. ADB doesn't even work.
Stock kernel from the ROM, Franco Kernel, ElementalX Kernel (Oreo), they all work fine.
