Q1. What is the difference between the "BSE" and "Standard" firmware?

The "BSE" (Buku Sekolah Elektronik) version is a special build for the Indonesian educational market, likely preloaded with digital textbooks and learning applications. The "Standard" version is the regular consumer software. For general use, the Standard version is recommended, but both should work on the device.

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

This is the most common issue with 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. 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.

Advan S7C (S716) Stock Firmware (All Versions) .pac File

Running on Android 5.1 Lollipop and featuring 3G connectivity, it’s designed for basic learning and browsing tasks. If your Advan S7C is bricked, stuck on the startup logo, or has become unusable due to software errors, flashing the official stock firmware is the definitive method to restore it to its original factory condition.

Important Note: This device is powered by a Spreadtrum (now UNISOC) chipset. The flashing process requires the SPD Upgrade Tool and a `.pac` firmware file. Following this guide will completely erase all your personal data.

🔧 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 could indicate a hardware revision mismatch. The Advan S7C may have been produced with different display components. If one firmware version causes issues, try flashing the other version provided in this guide.
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.
