+==== Upgrad from CyanogenOS to Android ====
+<note important>Disable disk encryption first!</note>
+==== Change disk encryption PIN on Android 7.2.1 Nougat ====
+  adb shell
+  su
+  vdc cryptfs changepw pin <old> <new>
+==== Install F-Droid Privilege Extension systemless ====
+//(e.g. needed for system on //sqashfs// which can not be modified by TWRP)//
+  - Install Magisk
+  - Install Magisk Systemizer extension
+  - Download F-Droid Privilege Exteion APK. (downloading, not installing!)
+  - connect via USB from PC and run<code>adb shell
+su
+cd /sdcard/Download
+systemizer</code>
+  - Select "Install from APK"
+  - Enter filename of apk
+  - Choose destination ''/system/priv-app/''
+  - Reboot Phone
+==== Install LineageOS 14.1 ====
+//Installing the LineageOS 14.1 update.zip on Android 7.2.1 //Nougat// following the simple((i.e. TWRP -> Install from ZIP)) update process did not work for me.//
+Install everything (but System) from Cyanogen 13.1.2 via fastboot first:
+  unzip cm-13.1.2-ZNH2KAS3LG-crackling-signed-fastboot-84f0d5200b.zip \
+        NON-HLOS.bin hyp.mbn emmc_appsboot.mbn rpm.mbn tz.mbn sbl1.mbn \
+        splash.img flash-radio.sh cache.img userdata.img boot.img recovery.img \
+        android-info.txt filesmap
+  su -
+  for file in boot.img cache.img recovery.img userdata.img ; do fastboot flash "${file%.img}" "$file" ; sleep 1 ; done
+Depending where you came from (i.e. what has been the previous OS Revision on the phone) you might want to flash further firmware:
+  ./flash-radio.sh
+Then reboot the //Swift// into the new fastboot:
+  fastboot reboot-bootloader
+In fastboot, boot TWRP:
+  fastboot boot twrp-3.2.3-0-crackling.img
+  exit # finish su
+In TWRP select "Advanced", then "ADB Sideload".
+You might want to tick "Wipe Dalvik Cache" and "Wipe Cache" to avoid problems due to cache inconsistency. Then start the sideload mode by doing the "Swipe to Start Sideload"
+Then install Lineage from PC((Might finish with "(~47%)    * failed to read command: Success" on the PC while everything is reported OK in TWRP))
+  adb sideload lineage-14.1-20180905-nightly-crackling-signed.zip
+In TWRP select "Reboot System"
+After reboot, wait for the installation process to finish. (If you think, its stuck - keep waiting provided the animated LineageOS Logo is still running)
+If you want to have //root// for apps, you need to install [[https://download.lineageos.org/extras|addonsu-14.1-arm64-signed.zip]]
+If you want to use //f-droid// with privilege extension, you need to install [[https://f-droid.org/de/packages/org.fdroid.fdroid.privileged.ota/|org.fdroid.fdroid.privileged.ota_2070.zip]]((ZIP herunterladen))
+==== Install LineageOS 16.0 over Android 7.1.2 ====
+//Haven't done it exactly this way - but in the end, it should be the same//
+  - Unlock phone
+  - Install TWRP 3.2.3-0
+  - Flash emmc_appsboot.mbn from cm-13.1.2-ZNH2KAS3LG-crackling-signed-fastboot-84f0d5200b.zip to aboot\\ ''unzip cm-13.1.2-ZNH2KAS3LG-crackling-signed-fastboot-84f0d5200b.zip emmc_appsboot.mbn''\\ ''fastboot flash aboot emmc_appsboot.mbn''
+  - Boot into recovery (i.e. TWRP)
+  - Wipe all data partitions (Well ... archive all needed data before ...)
+  - Reformat /system with ext4
+  - Format data
+  - Reboot
