A simple OTA REST Server for LineageOS OTA Updater System Application


Got a question? Not sure where it should be made? See CONTRIBUTING.


  • Apache mod_rewrite enabled
  • PHP >= 5.3.0
  • PHP ZIP Extension
  • Composer ( if installing via CLI )

How to use


$ cd /var/www/html # Default Apache WWW directory, feel free to choose your own
$ composer create-project julianxhokaxhiu/lineage-ota LineageOTA

then finally visit http://localhost/LineageOTA to see the REST Server up and running. Please note that this is only for a quick test, when you plan to use that type of setup for production (your users), make sure to also provide HTTPS support.

If you get anything else then a list of files, contained inside the builds directory, this means something is wrong in your environment. Double check it, before creating an issue report here.


$ docker run \
    --restart=always \
    -d \
    -p 80:80 \
    -v "/home/user/builds:/var/www/html/builds/full" \

then finally visit http://localhost/ to see the REST Server up and running.

Where to move built ROM ZIPs

  • Full builds should be uploaded into builds/full directory.
  • Delta builds should be uploaded into builds/delta directory.

ONLY for LineageOS 15.x and newer

If you are willing to use this project on top of your LineageOS 15.x ( or newer ) ROM builds, you may have noticed that the file named build.prop have been removed inside your ZIP file, and has been instead integrated within your file, which is basically an ext4 image ( you can find out more here: ).

In order to make use of this Server from now on, you MAY copy the build.prop file from your build directory ( where your ROM is being built ), inside the same directory of your ZIP and name it like your ZIP file name + the .prop extension.

For example, feel free to check this structure:

$ cd builds/full
$ tree
├── # the full ROM zip file
└── # the ROM build.prop file

What happens if no build.prop file is found

The Server is able to serve the ZIP file via the API, also when a build.prop file is not given, by fetching those missing informations elsewhere ( related always to that ZIP file ). Although, as it's a trial way, it may be incorrect so don't rely too much on it.

I am not sure how much this may help anyway, but this must be used as an extreme fallback scenario where you are not able to provide a build.prop for any reason. Instead, please always consider to find a way to obtain the prop file, in order to deliver a proper API response.

REST Server Unit Testing

Feel free to use this simple script made with NodeJS. Instructions are included.

How to integrate within your ROM

In order to integrate this REST Server within your ROM you have two possibilities: you can make use of the build.prop ( highly suggested ), or you can patch directly the android_packages_apps_CMUpdater package ( not suggested ).

Before integrating, make sure your OTA Server answers from a public URL. Also, make sure to know which is your path.

For eg. if your URL is http://my.ota.uri/LineageOTA, then your API URL will be http://my.ota.uri/LineageOTA/api


CyanogenMod / LineageOS ( <= 14.x )

In order to integrate this in your CyanogenMod based ROM, you need to add the cm.updater.uri property ( for CyanogenMod or Lineage ) in your build.prop file. See this example:

# ...
# ...

As of e930cf7:
Optional placeholders replaced at runtime:
{device} - Device name
{type} - Build type
{incr} - Incremental version

LineageOS ( >= 15.x)

In order to integrate this in your LineageOS based ROM, you need to add the lineage.updater.uri property in your build.prop file. See this example:

# ...
# ...

Make always sure to provide a HTTPS based uri, otherwise the updater will reject to connect with your server! This is caused by the security policies newer versions of Android (at least 10+) include, as any app wanting to use non-secured connections must explicitly enable this during the compilation. The LineageOS Updater does not support that.

Since is merged, the property cm.updater.uri is renamed to lineage.updater.uri. Make sure to update your entry.

As of 5252d60:
Optional placeholders replaced at runtime:
{device} - Device name
{type} - Build type
{incr} - Incremental version


In order to integrate this in your CyanogenMod or LineageOS based ROM, you can patch the relative line inside the package.

Although this works ( and the position may change from release to release ), I personally do not suggest to use this practice as it will always require to override this through the manifest, or maintain the commits from the official repo to your fork.

Using the build.prop instead offers an easy and smooth integration, which could potentially be used even in local builds that make use fully of the official repos, but only updates through a local OTA REST Server. For example, by using the docker-lineage-cicd project.



  • Add PHP 7.4 compatibility: Prevent null array access on isValid() ( thanks to @McNutnut )
  • Update RegEx pattern to match more roms than just CM/LineageOS ( thanks to @toolstack )
  • Use Forwarded HTTP Extension to determine protocol and host ( thanks to @TpmKranz )
  • Add detection of HTTP_X_FORWARDED_* headers ( thanks to @ionphractal )


  • Use md5sum files if available ( thanks to @jplitza )
  • Abort commandExists early if shell_exec is disabled ( thanks to @timschumi )
  • Update docs to match new uri formatting ( thanks to @twouters )
  • Add size field to JSON ( thanks to @syphyr )


  • Add support for missing build.prop file in LineageOS 15.x builds ( see #36 )
  • Provide a proper fallback for values if build.prop is missing, making the JSON response acting similar as if it was there


  • Add support for the new filename that UNOFFICIAL builds of LineageOS may get from now ( eg. ( thanks to @brianjmurrell )



  • Add support for the new id field for LineageOS ( see #32 )
  • Mention the need of the PHP ZIP extension in the README in order to run correctly this software ( see #27 )


  • Fix for "Fix for the timestamp value. Now it inherits the one from the ROM". The order to read this value was before the OTA server was aware of the content of the build.prop. ( thanks to @syphyr )


  • Added support for latest LineageOS ROMs that are using the version field ( see #29 )
  • Fix for the timestamp value. Now it inherits the one from the ROM ( see #30 )


  • Honor if present ( thanks to @ontherunvaro )
  • Add support for recursive subdirectories for full builds ( thanks to @corna )
  • Fix changelog URL generation ( thanks to @corna )
  • Add support for HTTPS OTA Url ( thanks to @corna )
  • Fix tutorial URL inside the ( thanks to @visi0nary )


  • Extend the legacy updater channel support to any Lineage ROM < 14.1


  • Add support for LineageOS unofficial keyword on API requests
  • Drop memcached in favor of APCu. Nothing to configure, it just works :)



  • Adding support for LineageOS CMUpdater ( this should not break current CM ROMs support, if yes please create an issue! )


  • Renamed the whole project from CyanogenMod to LineageOS
  • Added support for LineageOS ( and kept support for current CyanogenMod ROMs, until they will transition to LineageOS)


  • Loop only between .ZIP files! Before even .TXT files were "parsed" which wasted some memory. Avoid this and make the REST server memory friendly :)
  • HTML Changelogs! If you will now create a changelog file next to your ZIP file with an HTML extension ( eg. lineage-14.0-20161230-NIGHTLY-hammerhead.html ) this will be preferred over .TXT ones! Otherwise fallback to the classic TXT extension ( eg. lineage-14.0-20161230-NIGHTLY-hammerhead.txt )


  • Fix the parsing of SNAPSHOT builds


  • Final Fix for TXT and ZIP files in the same directory
  • Automatic URL detection for basePath ( no real need to touch it again )
  • Delta builds array is now returned correctly


  • Memcached support
  • UNOFFICIAL builds support ( they will be set as channel = NIGHTLY )
  • Fix Delta Builds path
  • Fix internal crash when *.txt files were present inside /builds/full path


  • Fix some breaking changes that will not enable the REST server to work correctly.


  • Excluded hiddens files and autogenerated ones by the OS (for example .something or Thumbs.db).


  • Refactored the whole code.
  • Now everything is PSR4 compliant.
  • Introduced composer.json to make easier the installation of the project.



Enjoy :)
