ForceScreencast

ForceScreencast is a utility toolkit designed to help users recover control of an Android phone with a dead or broken screen (black screen), even if "USB Debugging" is initially disabled.

Features

• OTG Control: Use your computer's keyboard and mouse to control the phone blindly (imitating a physical keyboard/mouse connection).
• Automated Enablement: Script (macro_enable_adb.ps1) to automatically navigate to Settings and enable USB Debugging.
• Blind Navigation Guide: Detailed tips on how to navigate Android without seeing the screen.
• Full Screencast: Once enabled, fully mirror and control the device using scrcpy.

Prerequisites

• Windows PC.
• USB Cable to connect the phone.
• Zadig: Tool for replacing USB drivers (Required for OTG mode).
• scrcpy: The scripts are configured for C:\Users\User\Desktop\scrcpy\scrcpy-win64-v3.3.4. If you have it elsewhere, edit strict paths in the .ps1 files.

Recovery Guide

Phase 1: Driver Setup (Crucial)

You must change your phone's USB driver for the "Blind" generic mouse/keyboard tool to work. Standard ADB drivers do not work for this mode.

1. Download Zadig (https://zadig.akeo.ie/).
2. Connect your phone via USB.
3. Open Zadig.
4. Click Options -> List All Devices.
5. Select your phone in the dropdown. (Name might be "Samsung", "Pixel", "Gadget Serial", or "Android").
6. Look at the Driver box on the right.
   • Goal: Change it to WinUSB.
   • Click Replace Driver (or Install Driver).
   • Wait for it to finish.

Status Check: Now your computer can "talk" to the phone as a Keyboard/Mouse. It CANNOT do normal ADB/File Transfer yet.

Phase 2: Run the Automation

You can either manually control the phone or use the included macro script.

Option A: Automated Script (Recommended)

1. Double-click run_macro.bat.
2. Manual Part: The script will launch a black window and PAUSE.
   • Unlock your phone manually (Spacebar to wake, Swipe Up with mouse, Type Password/PIN).
   • Open Settings manually (or ensure you are on the Home Screen).
3. Automated Part:
   • Once enabled, click the script window and Press ENTER.
   • Hands Off! The script will attempt to:
     • Swipe up and find Settings.
     • Enable Developer Mode (build number clicks).
     • Find Developer Options.
     • Enable USB Debugging.
     • Accept the "Allow USB Debugging?" popup (Right Arrow -> Enter).

Option B: Manual OTG Control

1. Double-click run_OTG.bat.
2. Use your keyboard and mouse to navigate blindly.
   • Wake: Spacebar.
   • Unlock: Click and Drag mouse UP. Type PIN.
   • Navigate: Arrow keys, Enter, Esc (Back).

Phase 3: Reset Drivers (Required for Screencast)

Now that USB Debugging is ON, you must switch the driver BACK so the Screencast app (ADB) can see the screen.

1. Close any running script windows.
2. Open Device Manager on your PC.
3. Locate your device (likely under "Universal Serial Bus devices" because we made it WinUSB).
4. Right-Click your device -> Uninstall Device.
   • Check the box "Attempt to remove the driver for this device".
   • Click Uninstall.
5. Unplug your phone.
6. Replug your phone. Windows should automatically reinstall the "Original" driver (MTP/ADB).

Phase 4: Start Screencast

1. Double-click run_screencast.bat.
2. You should now see your phone screen mirrored on your PC.

Blind Navigation Tips

Navigating a phone with a dead screen is difficult. Here are tricks to help you find your way.

The "Golden Ticket": TalkBack

If you can enable TalkBack (Screen Reader), the phone will tell you what you are selecting.

• Shortcut: Press Win+Alt+Enter (sometimes Ctrl+Alt+Enter or Hold Volume Up + Volume Down for 3 seconds).
• If enabled: You will hear "TalkBack On".
• Navigation changes:
  • Use Alt+Right / Alt+Left to move focus.
  • Use Alt+Enter to click.

Common Keyboard Shortcuts

• Wake Up: Press Space or Power Key.
• Unlock:
  • Swipe Up: Drag mouse up OR press Space then Tab then Enter.
  • PIN: Type numbers on Numpad. Enter.
• Go Home: Win+Enter or Esc multiple times.
• Notifications: Win+N.
• Settings: Win+N, then Right Arrow until you hit the gear icon.

Use Sound

Turn your volume UP.

• Lock/Unlock sounds indicate if the phone is awake.
• Charging sound confirms USB connection.
• Screenshot sound (PrintScreen) confirms the phone is on.

Navigating Settings Blindly (Generic Android)

1. Open Settings: Trigger Assistant (Win) and type "Open Developer Options" or "Open Settings".
2. Scroll to Bottom: Press End key. ("About Phone" is usually at the bottom).
3. Enter "About Phone": Press Up Arrow once or twice, then Enter.
4. Find Build Number: Press End (bottom), then Enter 7 times to enable Developer Mode.
5. Go Back: Esc.
6. Find Developer Options: It is often above "About Phone" or inside "System". Try Up Arrow -> Enter.
7. Enable USB Debugging:
   • Scroll down (Down Arrow x5-10).
   • One of the items is the toggle. Press Enter.
   • The Trap: A popup appears "Allow USB Debugging?".
   • Press Tab (or Right Arrow) to move focus to "Allow/OK".
   • Press Enter.

Troubleshooting

• Script types PIN but phone doesn't unlock? Timing might be off. Try manually unlocking before running the script.
• "USB Device not found"? You likely didn't perform Phase 1 (Zadig Driver Switch) or the driver reverted.
• "Device Unauthorized"? The automation failed to click "Allow" on the popup. Retry the process (Remember to switch drivers back and forth!).
