• Device not detected by fastboot: Reinstall drivers, use different USB port/cable, ensure fastboot mode active.
• “Waiting for device” in fastboot: Check USB, drivers; use sudo on Linux if permission issues.
• QFIL fails to communicate: Reinstall Qualcomm drivers; ensure device in EDL and appears as QDLoader 9008.
• Stuck in bootloop after flashing: Re-flash full ROM, perform factory reset, ensure vendor and firmware images match ROM.
• Partition size mismatch errors: Use full stock factory images designed for OnePlus 3T; some custom ROMs require modified partitions.

Step 3: Prepare the Phone and Launch the Tool

1. Power off your phone completely. If it’s hard bricked, it is already off, but hold the power button for 15 seconds to discharge any residual current.
2. Extract the unbrick tool folder to your desktop (avoid long file paths or spaces).
3. Run MsmDownloadTool.exe as Administrator (Right-click → Run as Administrator).

• If EDL flashing via software tools fails or device does not show QDLoader 9008, consider a repair shop experienced with Qualcomm programming or send to manufacturer service if under warranty (note: unlocking or third-party repairs may void warranty).
