  * As of 2018/02/26, this downloads around 12.6GB and 51,542 items for ''lineage-15.1'' ((not including LGE vendor files))
  * If pulling fresh sources, this command is good to leave running overnight, and then followed up with a [[#backup_sources | backup]]

  cd ~/'android/lineage-15.1' && repo sync --current-branch --network-only --jobs='4' --force-broken --force-sync && sync

=== Complete Sync ===

  * Performs both Network and Local file sync

  cd ~/'android/lineage-15.1' && repo sync --current-branch --network-only --jobs='4' --force-broken --force-sync && sync && repo sync --current-branch --local-only --jobs='16' && sync

==== Backup Sources ====

****

  cd ~/'android/lineage-15.1' && tar -c --use-compress-program='/usr/bin/pigz' -v -f ~/'Downloads/lineageos-lineage-15.1-'$(date +%Y-%m-%d)'.tar.gz' '.repo' && cd ~ && sync

==== Restore Sources ====

****

  mkdir -p ~/'android/lineage-15.1' && cd ~/'android/lineage-15.1' && tar -xvzf ~/'Downloads/lineageos-lineage-15.1-'*'.tar.gz' '.repo' && sync

====== Modifications ======

===== Allow Signature Spoofing =====

  * This allows **microG Services Core** and **FakeStore** to fake GApps properly

  * https://github.com/FreeMobileOS/android_packages_apps_GmsCore/blob/fmo-O-for-upstream/patches/android_frameworks_base-O.patch
  * Keep eyes on https://github.com/microg/android_packages_apps_GmsCore/pull/418 for when this is officially merged

  wget -O ~/'Downloads/GmsCore-android_frameworks_base-O.patch' 'https://raw.githubusercontent.com/FreeMobileOS/android_packages_apps_GmsCore/fmo-O-for-upstream/patches/android_frameworks_base-O.patch' && cd ~/'android/lineage-15.1' && patch --no-backup-if-mismatch --strip='1' --directory='frameworks/base' < ~/'Downloads/GmsCore-android_frameworks_base-O.patch' && rm -f ~/'Downloads/GmsCore-android_frameworks_base-O.patch' && sync

===== Allow Location Providers Outside /system =====

  * https://github.com/microg/android_packages_apps_UnifiedNlp/blob/master/patches/android_frameworks_base-N.patch
  * The ''N'' patch works on ''O'' ((Last tested: 2018/04/07))

  * This allows ** microG Services Core** to provide **UnifiedNlp** without having to be installed to ''/system/priv-app'' or having to have an outdated ''NetworkLocation.apk'' there

  wget -O ~/'Downloads/UnifiedNlp-android_frameworks_base-N.patch' 'https://raw.githubusercontent.com/microg/android_packages_apps_UnifiedNlp/master/patches/android_frameworks_base-N.patch' && cd ~/'android/lineage-15.1' && patch --no-backup-if-mismatch --strip='1' --directory='frameworks/base' < ~/'Downloads/UnifiedNlp-android_frameworks_base-N.patch' && rm -f ~/'Downloads/UnifiedNlp-android_frameworks_base-N.patch' && sync

===== Steven Black's Unified Hosts File =====

  * https://github.com/StevenBlack/hosts

  * Includes ''fakenews'' and ''gambling'' extensions

  rm -Rf '/tmp/unified-hosts' && git clone -b 'master' 'https://github.com/StevenBlack/hosts.git' '/tmp/unified-hosts' --depth '1' && python3 '/tmp/unified-hosts/updateHostsFile.py' --auto --extensions 'gambling' 'fakenews' --minimise --output ~/'android/lineage-15.1/system/core/rootdir/etc' && rm -Rf '/tmp/unified-hosts' && sync

====== Signed Build ======

===== Key Management =====

==== Generate ====

  * Change the ''x'' in ''emailAddress=''
  * If a backup exists and is being restored, **don't run this**

  subject='/C=US/ST=Pennsylvania/L=Charleroi/O=Realm of Espionage/OU=Android/CN=Sean Lynn Rhone/emailAddress=espionage724@x' && mkdir ~/'.android-certs' && for x in releasekey platform shared media; do ~/'android/lineage-15.1/development/tools/make_key' ~/'.android-certs'/$x "$subject"; done

==== Backup ====

****

  cd ~ && tar -cvzf ~/'Downloads/android-certs-'$(date +%Y-%m-%d)'.tar.gz' '.android-certs' && sync

==== Restore ====

****

  cd ~ && tar -xvzf ~/'Downloads/android-certs-'*'.tar.gz' '.android-certs' && rm -f ~/'Downloads/android-certs-'*'.tar.gz' && sync

===== Build =====

  * This takes around 2 hours to complete
  * If ''mka'' can't be found, make sure this is being ran from the Terminal window where previous commands took place

  cd ~/'android/lineage-15.1' && mka target-files-package dist && sync && jack-admin kill-server

===== Sign Build =====

****

  croot && ~/'android/lineage-15.1/build/tools/releasetools/sign_target_files_apks' -o -d ~/'.android-certs' ~/'android/lineage-15.1/out/dist/'*'-target_files-'*'.zip' ~/'android/lineage-15.1/signed-target_files.zip' && sync

===== Generate Zip =====

****

  ~/'android/lineage-15.1/build/tools/releasetools/ota_from_target_files' -k ~/'.android-certs/releasekey' --block --backup='true' ~/'android/lineage-15.1/signed-target_files.zip' ~/'Downloads/'$(date +%m-%d)'-oreo-los15.1-N5X-esp724.zip' && sync

==== brotli Fix ====

  * On 2018/02/26, LineageOS's ''common.py'' script expects the ''bro_cmd'' to call an executable called ''bro'', which doesn't exist since Fedora uses the full ''brotli'' name for the executable
  * The following ''cat'' command checks whether or not the above is true still
  * This copies the ''brotli'' executable from ''/usr/bin/brotli'' to the ''~/bin'' directory
  * Be aware of https://github.com/CopperheadOS/platform_build/commit/5c09ccfcd149784f92719fb32890b284164c427e in-case ''brotli'' still doesn't work

  cat ~/'android/lineage-15.1/build/make/tools/releasetools/common.py' | grep 'bro_cmd'

  cp '/usr/bin/brotli' ~/'bin/bro'

===== All-in-one =====

  * Builds the ROM, signs it, and generates a flashable zip
  * Includes the above brotli fix

  cd ~/'android/lineage-15.1' && mka target-files-package dist && sync && jack-admin kill-server && croot && ~/'android/lineage-15.1/build/tools/releasetools/sign_target_files_apks' -o -d ~/'.android-certs' ~/'android/lineage-15.1/out/dist/'*'-target_files-'*'.zip' ~/'android/lineage-15.1/signed-target_files.zip' && sync && cp '/usr/bin/brotli' ~/'bin/bro' && ~/'android/lineage-15.1/build/tools/releasetools/ota_from_target_files' -k ~/'.android-certs/releasekey' --block --backup='true' ~/'android/lineage-15.1/signed-target_files.zip' ~/'Downloads/'$(date +%m-%d)'-oreo-los15.1-N5X-esp724.zip' && sync
