Cách Kích Hoạt Unlock App Brevent Bằng Gỡ Lỗi Không Dây Android 11 Trở Lên Không Cần PC

Brevent is a premier background process manager and app freezing utility for Android that operates entirely without root privileges. Starting with Android 11 and newer, you can unlock Brevent directly on your phone using Wireless Debugging without needing a computer or USB cables, unlocking an embedded ADB shell terminal to run system optimization commands on the go.

Prerequisites: Your smartphone must run Android 11, 12, 13, 14, or 15 and be connected to an active Wi-Fi network. Android's native Wireless Debugging subsystem cannot initialize over standard cellular data connections (4G/5G).

Step 1: Enable Developer Options by Phone Manufacturer

Android device makers locate Developer Options under varying menu paths. Use the reference table below to activate development privileges on your specific device:

Manufacturer / Skin Settings Navigation Path Unlock Trigger
Samsung (One UI) Settings > About phone > Software information Tap Build number 7 times consecutively.
Xiaomi, Redmi, POCO (MIUI / HyperOS) Settings > About phone Tap MIUI version / OS version 7 times.
Oppo, Realme, OnePlus (ColorOS / Realme UI) Settings > About device > Version Tap Build number 7 times.
Vivo, iQOO (Funtouch OS / OriginOS) Settings > More settings > About phone Tap Software version 7 times.

Step 2: Turn On Wireless Debugging in Developer Options

  1. Return to the main Settings screen on your smartphone.
  2. Scroll down to open Developer options (often found under System or Additional settings).
  3. Toggle on standard USB debugging.
  4. Scroll further down and locate Wireless debugging.
  5. Toggle the switch to ON and check "Always allow on this network" when prompted.

Step 3: Pair Brevent Using Split-Screen or Pop-up View

Android's security architecture automatically refreshes the pairing port and 6-digit PIN whenever full-screen app switching occurs. Using Split-Screen or Pop-Up View ensures continuous synchronization during pairing:

  1. Install Brevent from the Google Play Store or GitHub releases.
  2. Open Brevent, navigate through the introductory screens, and select Wireless Debugging Port.
  3. Open your phone's Recent Apps view, long-press the Brevent app icon, and select Open in split-screen view (or Pop-up view).
  4. In the secondary window pane, open Settings > Developer options > tap directly on Wireless debugging.
  5. Tap Pair device with pairing code.
  6. A popup displays the 6-digit Wi-Fi pairing code and the IP address & dynamic 5-digit port.
  7. Enter the 6-digit pairing code into Brevent's pairing input field, verify the corresponding port number, and tap Wireless Pair.
  8. Within 3 to 5 seconds, Brevent will indicate "Success" and transition to its active management dashboard.

Step 4: Execute ADB Shell Commands via Exec Command

Once Brevent is unlocked, you possess an interactive ADB shell terminal capable of executing elevated maintenance commands on-device:

  1. Inside Brevent, tap the hamburger menu (3 horizontal lines) in the top-left corner.
  2. Select Exec Command.
  3. Type your desired shell command and tap the Run button (green play icon).

Essential High-Performance Commands:

1. Grant secure system settings writing permissions to SetEdit:

bash
pm grant by4a.setedit22 android.permission.WRITE_SECURE_SETTINGS

2. Force continuous 120Hz display refresh rate:

bash
settings put system peak_refresh_rate 120.0settings put system min_refresh_rate 120.0

3. Trigger storage garbage collection and flash trim (fstrim):

bash
sm fstrim

4. Optimize all installed applications using Android Dexopt compilation:

bash
cmd package compile -m speed-profile -a

Step 5: Freeze Background Drainers with Brevent

Beyond running terminal commands, Brevent's primary capability is enforcing instant app hibernation:

  • In Brevent's app list, long-press apps prone to excessive background wakeups (e.g., social feeds, ecommerce apps, heavy games).
  • Tap the Brevent icon on the top action bar to mark them.
  • Whenever you exit marked applications, Brevent immediately suspends their background execution threads, preventing overnight standby battery drain and preserving RAM.

Comparison: Wireless Debugging vs. Traditional PC Activation

Evaluation Criteria Wireless Debugging (Recommended) USB Cable + Desktop PC
Hardware Needed Only your smartphone and a Wi-Fi connection. Requires a PC/laptop and a verified data cable.
Android Version Support Android 11, 12, 13, 14, 15. All legacy versions (Android 5.0 through 15).
Setup Duration 1 to 2 minutes directly on the device. 5 to 10 minutes including driver setup.
Portability Re-activatable anywhere with Wi-Fi availability. Tethered to a physical computer workstation.

Frequently Asked Questions (FAQ)

Does restarting my phone deactivate Brevent?

Yes. By Android system design, all active ADB shell processes (including Shizuku and LADB) terminate upon system reboot. When rebooted, simply connect to Wi-Fi and pair the 6-digit PIN again in under 30 seconds.

Why does Brevent throw "Wireless Debugging Port Failed"?

This occurs when full-screen switching causes Android to assign a newly randomized port before pairing finishes. Always utilize Split-Screen mode to keep Developer Options and Brevent simultaneously visible.

Can I activate Brevent without an external Wi-Fi router?

Yes, through a simple workaround: connect your phone to a temporary mobile hotspot hosted by a secondary smartphone. Once Brevent verifies activation, you can disconnect and return to mobile data freely.
