This custom ROM is created to provide a totally new experience to Low end Mediatek devices.

• It is focused on stability while upgrading the android version so we can test new One Ui releases and adding new features such as Galaxy AI✨

What it does?

It downloads the firmware from Samsung servers using samloader, or custom firmware downloader, merges OTA patches, extracts the partition images and then applies all the features implemented in the repository - Galaxy AI, heavy debloat, Knox patches, performance tweaks and QoL improvements - so the device can be used again with a fresh and modern experience.

The whole process can run either on GitHub Actions or locally on your machine (requires Ubuntu/Debian distro or WSL).

Changelogs

Refer to changelogs folder to know more about releases and useful information.

How to Use

Method 1: GitHub Actions

1. Fork the Repository

Give a ⭐ star to the repository. Fork the repository to your GitHub account.

2. Run the Workflow:

Open your forked repository.

• Go to the Actions tab.
• Select LumiROM Tools.
• Click Run workflow.

3. Set Your Device Model:

Update your device model in the STOCK_DEVICE_MODEL option.

• If your model is available in /LumiROM/Devices folder of this repository, the tool will work for your device.
• If your model is not present, it will not work.

I recommend for forks, to use the Specific Device workflow instead of the All Devices workflow if you building it via GitHub Actions.

4. Kernel BPF Version Option:

Set this option to True if your kernel BPF version is 5.4 (lower than 5.10).

• Otherwise, set it to False.

5. Output Filesystem:

My tool can only build images in erofs because:

• It is recommended if your device partition size is small.
• Saves storage space.
• Can add more things as it gets compressed

Only downside is: Your kernel must support EROFS.

But all of the devices I support got EROFS kernel so there isn't a problem

6. Upload (only on GH Actions)

The ROM will be auto uploaded to Hugging Face servers, but you need to create an account and generate a token to be able to upload the file.

Tip

• Create a Hugging Face account.
• Go to settings and then to Access Tokens. Create a new token with write permissions and copy it.
• Create a bucket.
• Go back to the repository and go to repository settings and add the token as a secret with the name HF_TOKEN.

Method 2: Local Build

You can also build LumiROM directly on your Linux machine using the local build script. This method includes a firmware cache system so you only need to download the firmware once.

1. Clone the repository:

git clone https://github.com/Luminous418/LumiROM.git
cd LumiROM

2. Configure your build:

You will find these variables on build_local.sh:

STOCK_DEVICE="$1"               # Your device model
TARGET_DEVICE="$2"              # The phone you want to port
TARGET_CSC="$3"                 # The region from the target device
TARGET_IMEI="$4"                # The IMEI from target device
USE_MODS="Yes"                  # Include mods (Vulkan fix, VoLTE fix, tweaks, wallpapers)
USE_GALAXY_AI="Yes"             # Include Galaxy AI features
USE_UI_8_TETHERING_APEX="False" # Set to True if kernel BPF < 5.10

3. Run the build:

The use for this is:

bash build_local.sh <STOCK_MODEL> <TARGET_MODEL> <CSC> <IMEI>

Change accordingly to your needs but dont touch the $1, $2 etc.
The script will install dependencies, download firmware (if not cached), apply all patches and build the ROM. The output ZIP will be in the ROM/ folder.

4. Manage firmware cache:

Use the cache manager to check, list or clear your cached firmware images:

bash scripts/cache_manager.sh status    # Show cache status
bash scripts/cache_manager.sh check     # Verify required images
bash scripts/cache_manager.sh size      # Show cache size
bash scripts/cache_manager.sh list      # List all images with sizes
bash scripts/cache_manager.sh clear     # Clear cached images

Important

If you're building locally, script will log all actions that is happening, if something fails, report the error to me via GitHub issues or on my Telegram channel by uploading the LOGS folder.

Note

If you dont wanna mess with the repo or dont know how to do any of this things, I will continue releasing updates of my rom on my Telegram channel, that you can join clicking on the link on the repository bio. Also I accept suggestions aswell as im still learning from it, so if you see a bug, or wanna make the code a bit more easy to understand, you can always create a pull request!
