How to install INTELLIGENT INVERTER PUMP v4.2.7 on Android API 17+
Takes about 2 minutes. You'll need roughly 2.3 MB of free storage.
- Grab com.dafeng.prodn_47.apk — hit the Download button above (2.3 MB). 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 764676fe2cd7e9ee…. Any difference means the file is corrupted or tampered — delete and re-download.
- Open the APK — tap the download notification, or find com.dafeng.prodn_47.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=Liu Wei, OU=dafeng, O=DaFeng, L=HangZhou, ST=Zhejiang, C=China. 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 TRUSTED).
- Done — open INTELLIGENT INVERTER PUMP — tap Open on the install screen, or find the INTELLIGENT INVERTER PUMP icon in your app drawer.
