An Android app that resolves Android 16 downloadCheck links into their final direct download URLs.
This tool is designed for developers, testers, and enthusiasts who need to analyze or inspect OTA redirect links in a simple and clean way.
The app takes a downloadCheck URL as input, follows all HTTP redirects using proper request headers, and returns the final resolved download link.
It does not download firmware — it only resolves publicly accessible redirect URLs.
- Resolves shortened or redirected OTA URLs
- Handles multiple redirect chains
- Verifies whether the final result is a direct download link
- Clean and minimal Jetpack Compose UI
- Fast and lightweight
- No tracking, no ads
- Open the app
- Paste your
downloadChecklink - Tap Resolve
- Copy or share the final resolved URL
