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

This is the most frequent issue with SPD flashing and it indicates a communication failure. It's almost always caused by incorrect drivers or an improper connection sequence. Re-install the SPD SCI drivers and ensure you press and hold the Volume Down key *before* connecting the USB cable.

Q2. Will this fix Face Unlock if it has stopped working?

If the Face Unlock feature stopped working due to a software glitch or corrupted system file, then a full firmware flash will restore the original software and should fix it. If the problem continues after a clean flash, it likely points to a hardware issue with the front-facing camera.

Q3. My IMEI is invalid after flashing. What can I do?

Losing the IMEI number is a risk when flashing UNISOC/Spreadtrum devices. This firmware will not restore it. You will need a dedicated SPD IMEI repair tool to write your original IMEI number back to the phone. The original number can usually be found on the phone's retail box or SIM tray.

Advan G5 Stock Firmware (UNISOC SC9863A) .pac File

The Advan G5 is a budget-friendly 6.2-inch smartphone from the Indonesian brand Advan, released in 2020. It was notable for bringing features like a triple camera system and Face Unlock to the entry-level market, running on Android 10. If your Advan G5 is bricked, stuck in a bootloop, or has been infected with malware, flashing the official stock firmware is the definitive method to restore the device to its original factory condition.

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

🔧 Device-Specific Troubleshooting

Phone Not Detected by PC: If drivers are installed correctly, the issue is likely the boot key sequence. Make sure the phone is completely powered off. Hold Volume Down (or, in some cases, Volume Up) firmly *before* you plug in the USB cable. A new device should briefly appear in your Windows Device Manager when connected correctly.
“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 high-quality data cable. A corrupted .pac file can also be the cause, so try downloading the firmware again. For newer chipsets like the SC9863A, you may sometimes need a more recent version of the ResearchDownload tool if the Upgrade Tool fails.
Camera Errors After Flashing: This firmware contains the correct drivers for the Advan G5’s triple camera system. If you receive “Cannot connect to camera” errors after a successful flash and a factory reset, it may indicate a hardware failure in one of the camera modules.
Stuck on Advan Logo After a “Passed” Message: If the flash completes successfully but the phone won’t boot, a factory reset is necessary. Boot into recovery mode (usually by holding Power + Volume Up), and from the menu, select “wipe data/factory reset.” This will clear old data and allow Android 10 to boot correctly.
