  1. Would I need to follow this process when a new version of the ROM is available? Also, after my phone boots and everything is done loading, if I reboot the phone (simple reboot, just a restart) it gets stuck in a bootloop, just showing the model number of the phone screen… I have to go through the whole wipe+install process again. what could be wrong?

    • You should always clean flash the new ROM.But the ROM is a update of older one.You can just flash it via the latest Recovery.

      • Do I download the RR file or the LineageOS file or both as well as the incr file? This $*%# is not very user friendly and I’m no noob… Thanks in advance chum.
