YunuUSBNet is an ultra-lightweight, portable Windows GUI wrapper built in AutoIt for Gnirehtet and ADB. It shares your PC/Laptop's internet connection (Ethernet or Wi-Fi) with an Android smartphone via USB reverse-tethering — no root, no complicated CMD commands, no driver hell.
It's purpose-built for budget and low-spec PCs (2GB RAM) — the kind of "potato PC" that chokes on heavier tethering tools. YunuUSBNet strips away the bloat and gives you a clean, one-click GUI on top of the proven Gnirehtet engine.
Perfect for:
- 💻 Old laptops / budget PCs with 2GB RAM
- 🏢 Office or campus computers with strict spec limits
- 📶 Areas with no Wi-Fi but a spare Android phone with mobile data (or vice versa)
- 🙅 Anyone tired of fiddling with raw
adbandgnirehtetCMD commands
- 🚪 Smart Startup Gatekeeper & GDI+ Engine: Introduced an intelligent startup splash gate with high-quality bicubic image rendering (
yunu00.png/yunu01.png). Scans Windows PnP hardware for official Android Vendor IDs (Google, Xiaomi, Samsung, Oppo, Realme, MediaTek, Transsion/Infinix) and opens automatically upon cable insertion. Includes an instant Dev Bypass for testing without physical devices. - 🛠️ Protected Developer Mode & Dynamic UI: Unlock real-time raw telemetry logs via password authentication (
yunu). Features dynamic window geometry resizing (490px compact mode vs. 625px extended telemetry mode) with nativeGUIResizeModeprotection to prevent button stretching. - ⚡ Isolated ADB Engine (0ms Anti-Deadlock): Complete overhaul of the ADB execution pipeline. Goodbye hanging processes and Stdout pipe buffer freezes! ADB commands now run via isolated temp stream redirection backed by a strict 2,500ms timeout watchdog kill.
- 📶 Adaptive 75% Smart Data Tier Pipeline: Integrated an unlimited data quota tracker driven purely by physical network octets. The progress bar automatically doubles target capacity (1 GB -> 2 GB -> 4 GB ...) whenever 75% of the current tier is reached.
- 🛡️ Continuous Explorer Popup Guard: Say goodbye to annoying Windows AutoPlay / MTP File Explorer popups every time you plug in your phone! Automatically intercepts, detects, and closes newly spawned
CabinetWClasswindows in the background within a 4-second window. - 🤖 Deep Android System Tuning: Automatically injects shell optimizations before establishing the tunnel: disables conflicting phone Wi-Fi, wipes stubborn HTTP proxy settings, wakes up the screen (
keyevent 224), dismisses keyguard, and whitelists Gnirehtet from Android battery Doze Mode. - 🪟 Taskbar Crash Guard & 3-Way Exit Modal: Handled Win32
TaskbarCreatedmessages so the notification tray icon automatically re-registers ifexplorer.execrashes. Added an elegant close confirmation modal allowing users to choose between Full Exit, Minimize to Tray, or Cancel. - 📜 Smart 3-Session Rolling Logger: Replaced infinite log file bloat with a smart rolling parser that cleanly retains only the last 3 active sessions, complemented by millisecond-precise developer telemetry logs (
filelogdeveloper.txt). - 🔄 Dual-Track Jitter Recovery: Added a 1.5-second debounce cooldown filter to handle physical USB cable shakes/jitters seamlessly without triggering destructive ADB resets.
This is the first official release of YunuUSBNet. Here's everything packed into it:
- Real-time network speed display showing both
KB/s(orMB/s) andMbpssimultaneously — e.g.768.0 KB/s (6.1 Mbps). - Powered by a WMI Raw Performance Engine (
Win32_PerfRawData_Tcpip_NetworkInterface) with a 2-sample Moving Average smoothing filter to eliminate false0 KB/sdips. - Dynamic 4-State Color Matrix: switches between Theme Blue (
#00AAFF) when active and Gray (#666666) when disconnected/idle — with zero flicker. - Flat visual progress meter bars rendered via native Windows
uxtheme.dllcalls. - WMI Warm-Up on launch: instantly detects PC internet status at startup via ping and octet checks.
- Non-Destructive Instant Re-Attach (~100ms): automatically re-injects Gnirehtet without killing the ADB daemon or corrupting the phone's ADB session when physical micro-jitters occur.
- Soft Hysteresis Retry Loop: 3x soft retries before escalating, making the connection immune to continuous cable shaking/vibration ("Rage-Gamer Proof").
- Windows PnP Auto-Heal (
WM_DEVICECHANGE0x8000/0x8004): listens directly to Windows OS PnP kernel hardware messages for near-instant reconnection on USB insertion — fixes the classic "ding-dong" USB sound lockup. - Offline Device Auto-Recovery: automatically issues
adb reconnect offlineif ADB desyncs. - Graceful Android VPN Teardown: sends
gnirehtet stopandam force-stopto the phone before closing PC-side processes on manual disconnect.
- Single-Instance Enforcer (
_Singleton): prevents multiple instances from fighting over USB sockets. - Explicit System Path Resolution (
@SystemDir): protects against Windows%PATH%corruption or DLL side-loading. - Memory & Handle Leak Prevention: explicit
StdioClose()handle cleanup and 15,000-character log buffer auto-purge. - High Priority Elevation (
ProcessSetPriority(4)): elevates Gnirehtet to High Priority to prevent ping spikes during heavy gaming or 100% CPU load. - 0% CPU Idle Footprint: non-blocking single-loop execution with
Sleep(10)yield.
- Minimize (
_): minimizes normally to the Windows Taskbar. - Close (
X): hides to the System Tray near the clock only when a connection is active. Exits completely when stopped. - Left-Click Tray Icon: instantly restores and activates the main window.
- Headless Mode (
--background): command-line argument support for silent execution without a GUI.
- 📊 Dual-Unit Live Speedometer — See real-time speed in

💡 Tip for First-Time Users: If your phone isn't detected, install the correct USB/ADB driver for your device model first, then reconnect the cable.
Reads live traffic counters straight from Windows' WMI performance layer and applies a 2-sample moving average, so the number you see is smooth and accurate instead of jumping to 0 KB/s between polling intervals. Both KB/s/MB/s and Mbps are shown together so you don't have to do the math yourself.
USB reverse-tethering is notoriously fragile — a loose cable or a bump on the desk usually kills the whole session and forces a full restart. YunuUSBNet listens directly to Windows' PnP hardware events and re-injects the Gnirehtet tunnel in roughly 100ms, without tearing down the underlying ADB session. Combined with the soft hysteresis retry loop, this makes the connection resilient enough to survive continuous cable movement.
Because the tool is meant to run for hours in the background on low-spec machines, every part of the codebase is written to avoid leaks: handles are explicitly closed, the log buffer is capped and auto-purged, and only a single instance is ever allowed to run — preventing two copies from fighting over the same USB socket.
YunuUSBNet only occupies your taskbar or tray depending on connection state — it disappears completely once you've stopped tethering, so it never lingers as background clutter.
Tested on a potato PC — Intel i3 2nd Gen + 2GB RAM:
| Tool | RAM | CPU (Idle) | CPU (Active) | Setup Time |
|---|---|---|---|---|
| YunuUSBNet | 3–8 MB | 0–1% | 1–2% | ~10 sec |
| Official Gnirehtet CMD | 30MB+ | 1–3% | 3–5% | ~2–5 min |
| Commercial Tethering Tool | 150MB+ | 3–5% | 5–10% | ~1–3 min |
YunuUSBNet uses up to 4–5x less RAM than a typical commercial tethering tool, while staying just as fast — because it's just a thin, well-optimized GUI shell around Gnirehtet, not a reinvented network stack.
Q: My phone isn't detected at all? A: Make sure USB Debugging is enabled and you've accepted the "Allow USB Debugging" prompt on the phone. Reinstall the correct ADB driver for your device if needed.
Q: The connection drops when I move the cable slightly? A: This is exactly what the Hardware Resilience system is built to fix — update to the latest version. If it still happens, try a different USB cable (some cheap cables have poor shielding).
Q: The speedometer shows 0 KB/s even though internet is working?
A: Wait a few seconds for the WMI Warm-Up to finish detecting your active network adapter, or check that your PC's internet connection itself is active.
Q: ADB says "device offline"?
A: YunuUSBNet automatically issues adb reconnect offline in the background. If it persists, unplug and replug the USB cable once.
Q: The app won't close from the tray icon? A: By design, YunuUSBNet only fully exits when the connection is stopped — this prevents an abrupt VPN teardown on the phone. Click Stop first, then close.
Q: Can I run it without a visible window?
A: Yes — launch it with the --background argument for headless/silent mode.
