How to install USB Host Diagnostics v1.3 on Android API 9+
Takes about 2 minutes. You'll need roughly 67.5 KB of free storage.
- Grab eu.chainfire.usbhostdiagnostics_13.apk — hit the Download button above (67.5 KB). If your browser warns about APK files, choose Keep or Download anyway — that warning fires on every APK, not just this one.
- Trust your browser to install — on Android 8+ go to Settings → Apps → Special access → Install unknown apps, pick the app you downloaded with (Chrome, Firefox, Files, etc.), and flip Allow from this source. On older Android, toggle Unknown sources under Security.
- (Optional) Verify the file — compute the MD5 of the downloaded APK and make sure it matches 2d7ec8ae7a07c887…. Any difference means the file is corrupted or tampered — delete and re-download.
- Open the APK — tap the download notification, or find eu.chainfire.usbhostdiagnostics_13.apk in your Files app under Downloads, then tap it. Android's package installer will appear.
- Check the signer — the install screen will name the publisher. For this build it should read CN=Chainfire, OU=Unknown, O=Unknown, L=Unknown, ST=Unknown, C=NL. If it doesn't match, cancel — you have the wrong file.
- Review permissions & tap Install — scroll the permission list, then confirm. If Play Protect flags it, tap Install anyway (this APK was scanned as WARNING).
- Done — open USB Host Diagnostics — tap Open on the install screen, or find the USB Host Diagnostics icon in your app drawer (this build targets armeabi-v7a devices).
Common install errors for USB Host Diagnostics
- "App not installed" — usually means an older or differently-signed version is already on your device. Uninstall it first, then retry. Your data may be lost unless you back it up.
