    Starting from LineageOS 15.1, LineageOS team has made stringent device support norms, which ensures that almost every important piece of hardware present on a phone MUST be in a working state on an OFFICIAL LineageOS 15.1 build.

    Upgrading from earlier version of OFFICIAL LineageOS 14.1 or Lineage OS 15.1 for Nexus 4 (mako):

    If you are on an OFFICIAL LineageOS 14.1 (yes, I mean the Android Nougat based OFFICIAL LineageOS 14.1) then you don’t need to wipe the data and you can upgrade to the OFFICIAL LineageOS 15.1 on Nexus 4 just by cleaning the system partition.

    • Copy the latest Nexus 4 Lineage OS 15.1 ZIP file, Oreo 8.1 GApps and/or supersu ROOT package to the phone or use the updater app to download the LineageOS 15.1 on Nexus 4.

      NOTE:
      – If you are on an OFFICIAL LineageOS 14.1 then you will be allowed to download the latest OFFICIAL LineageOS 15.1 using the updater app but you won’t be allowed to upgrade to LineageOS 15.1 on top of LineageOS 14.1
      – So, you need to export the downloaded LineageOS 15.1 ROM build file to the SD card or phone memory from the updater app:
      You can export the downloaded package to the sdcard/phone memory from the Updater app by long-pressing the downloaded file and then selecting “Export” on the top menu

    • Boot into Recovery.

      – Make sure you have a latest custom Recovery that should be able to flash the LineageOS 15.1 on Nexus 4.
