A modern, open-source project designed to bring YouTube back to Java phones. It uses a proxy to bypass modern HTTPS and API requirements that old phones can't handle.

A 240x320 device often has less than 2MB of heap memory available for the app to run. Where to Find the Files

To get YouTube running in 240x320 now, developers use or J2METube . These are "new" clients designed to bypass the old API restrictions by routing traffic through a proxy server that handles the heavy lifting. Key Features of the 240x320 Version:

If you need a included for a specific trusted site. The desired tone (e.g., more technical, or nostalgic).

Modify the application properties to change the video endpoint from https:// to http:// . Alternatively, utilize a custom proxy server that strips the secure layer before reaching the local router. 3. "Video Not Supported" / "Playback Error"

It relies on your phone’s native media player (usually via RTSP streaming protocols or direct 3GP streams) to display the video. 2. Opera Mini + Proxy Video Downloader Web Services

Most YouTube videos are now in VP9 or AV1 formats. JAR players must request the 3GP or low-quality MP4 streams which are increasingly rare.

Cloud servers pre-compress metadata into tiny, text-only formats. Used basic RTSP 3GPP streaming links.

.jar (Java Archive) files are compressed packages containing the user interface, icons, and instructions needed to run software on a feature phone.

This is the most reliable solution disguised as one file.

The phone's built-in root certificates have expired, failing the secure handshake.

You will not get HD streaming. You will not get live chat. You will likely only get audio or 144p video at 5 frames per second. However, for a retro enthusiast or a user with a dirt-cheap dumbphone as a daily driver, successfully installing a patched YouTube jar is a victory of digital autonomy.

aimed at bringing modern video streaming to classic feature phones . In the early mobile era, Java ME (J2ME) powered billions of devices using small .jar files optimized for the standard 240x320 pixel resolution. Today, dedicated homebrew developers keep these vintage handsets functional by building custom YouTube clients that bypass outdated code and connect to modern servers.

Bring some modern entertainment to your classic hardware. Happy watching! If you'd like to , let me know:
