🚀 Getting Started

Recommended Installation Method

The recommended way to install TreeFrogUI is with the official TreeFrogUI Installer.

The installer handles the required device-specific setup and is available for:

  • Windows

⚠️ Important

Do not install TreeFrogUI over the factory/preinstalled SD-card operating system.

TreeFrogUI should be installed on a freshly prepared SD card.

Installing it directly over the factory system may result in issues such as:

  • missing or broken audio;
  • incorrect controls;
  • display problems;
  • crashes;
  • boot failures.

Whenever possible, keep a backup of your original SD card and use a separate, good-quality SD card for TreeFrogUI.
