Hey thanks. I will try installing LineageOS. I was having double mind about going back to Cyanogenmode or Lineage but now I will try installing LineageOS.

I installed Ubuntu touch in my one plus one device and now I am not able to dual boot android in it. I want to wipe out ubuntu and re install cyanogen mode Android in it. Can some one guide me through the process or lead me to some blog or portal where I can get right guidance.

Thanks.
