Step-by-Step Fix for Android Pie (Realme 2 Pro):
- Manually Allow VPN Permission Open Gnirehtet app directly on your phone.
It should prompt you for VPN permission.
Tap Allow (even if you're using adb from PC).
ColorOS may silently block VPN permission if started from adb without manual approval.
- Turn Off Battery Optimization for Gnirehtet Go to Settings → Battery → App battery management
Find Gnirehtet
Set to "No Restrictions" or "Don't optimize"
- Check "Auto Launch" Settings (ColorOS Specific) Go to Settings → App Management → Gnirehtet → Auto Launch
Turn ON Auto Launch
Also allow background activity and secondary launch 4. Install Gnirehtet Manually (If Needed) In case installation failed:
Download the .apk from the official repo
Push manually:
adb install gnirehtet.apk Then start it:
adb shell am start -a com.genymobile.gnirehtet.START 5. Check USB Debugging Go to Developer Options
Make sure USB Debugging is ON
Try adb devices to confirm your phone is connected properly
Still Not Working? Some Realme/ColorOS devices block VPN apps launched via ADB, especially if you're not allowing VPN permissions manually.
