Q1. What does "5G WIFI" in the firmware name mean? Does my tablet support 5G?

This refers to the tablet's ability to connect to 5GHz Wi-Fi networks, which are generally faster and less congested than the standard 2.4GHz band. It does not mean the tablet supports 5G cellular data networks.

Q2. Why is the flashing tool stuck at "Checking Baudrate"?

This is the most common issue when using the SPD Upgrade Tool. It indicates a communication failure, 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.

Q3. Can this firmware fix my tablet if it won't detect my SIM card?

If the issue is software-related, a full flash should restore the modem drivers and fix it. However, if the flash completes and the SIM card is still not detected, or if your IMEI shows as "Invalid," the NVRAM partition may be corrupted. This requires an advanced repair using a separate SPD IMEI tool.

Advan Tab 8 (8002) Stock Firmware (Android 9.0) .pac File

The Advan Tab 8 (model 8002) is an 8-inch 4G LTE tablet from the Indonesian brand Advan, released around 2020. Running Android 9.0 Pie and powered by a UNISOC octa-core processor, it serves as a capable budget device for media consumption and online learning. If your Advan Tab 8 is bricked, stuck on the startup logo, or experiencing severe software issues, flashing the official stock firmware is the definitive method to restore it to its original factory condition.

Important Note: This tablet uses a UNISOC (formerly Spreadtrum) chipset, and the firmware is a `.pac` file. The flashing process must be done using the SPD Upgrade Tool and will completely erase all your personal data.

Q2. Why is the flashing tool stuck at “Checking Baudrate”?: This is the most common issue when using the SPD Upgrade Tool. It indicates a communication failure, 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.

🔧 Device-Specific Troubleshooting

Device 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 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. For newer UNISOC chipsets, you may sometimes need a more recent version of the ResearchDownload tool.
Wi-Fi or Bluetooth Not Working After Flash: This firmware contains the correct drivers for the Advan Tab 8. If these features do not work after a successful flash and a factory reset, it could indicate a hardware failure with the tablet’s internal connectivity chip or antenna.
Stuck on Advan 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.
