Q1. Why is the flashing tool stuck on "Checking Baudrate"?

This is the most common issue when using the SPD Upgrade Tool and it indicates a communication failure. This is almost always caused by an incorrect driver installation or not using the correct boot key sequence. Re-install the SPD drivers and ensure you are pressing and holding the Volume Down key *before* connecting the USB cable.

Q2. Can I use this firmware to upgrade my tablet to a newer Android version?

No. This is the official Android 5.1 Lollipop firmware, which was the final OS version officially released for the BQ-9011G Vision.

Q3. My tablet's IMEI is null after flashing. How do I fix it?

Losing the IMEI is a risk when flashing Spreadtrum devices. This firmware will not restore it. You will need a separate SPD IMEI repair tool to write your original IMEI numbers back to the device. The original numbers are printed on the tablet's retail box or on a sticker in the SIM card slot area.

🔧 Device-Specific Troubleshooting

Tablet Not Detected by PC: If drivers are properly installed, the problem is likely the connection method. Ensure the tablet is completely powered off. Hold the boot key (Volume Down is standard, but some devices use Volume Up) firmly *before* you plug in the USB cable. You should see a new device appear in your Windows Device Manager.
“Operation Failed” Error During Flashing: If the process starts but then fails, try using a different USB port (USB 2.0 is often more reliable) and a known-good data cable. The .pac file could also be corrupted, so downloading the firmware again is a good step.
Display or Touchscreen Issues After Flashing: If the flash is successful but the screen has wrong colors or the touchscreen doesn’t respond, it indicates a hardware revision mismatch. The BQ-9011G may have been produced with different display components. This firmware is the standard version, but in rare cases, a different build might be needed if you face such issues.
Stuck on BQ Logo After a “Passed” Message: If the flash completes successfully but the tablet won’t boot, a factory reset is necessary. Boot into recovery mode (usually by holding Power + Volume Up), and in the menu, select “wipe data/factory reset.” This will clear old data conflicts and allow the new system to boot.
