Q1. Will this firmware 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.

Q2. 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.

Q3. My phone'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 a sticker found under the phone's removable battery.

If the problem continues after a clean flash, it likely points to a hardware issue with the front-facing camera.
Q2. 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.

🔧 Device-Specific Troubleshooting

Phone Not Detected by PC: The removable battery is helpful for troubleshooting. If the phone is not detected, the issue is almost always the SPD SCI drivers. Re-install them correctly on your PC. Then, click “Download” in the tool *before* connecting the phone without its battery while holding the boot key.
“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. For newer UNISOC chipsets like the SC9863A, you may sometimes need a more recent version of the ResearchDownload tool if the Upgrade Tool fails.
4G LTE / SIM Card Not Working: If your phone doesn’t detect the SIM card or has no network signal, the first thing to check is the IMEI by dialing *#06#. If it shows “Invalid” or is blank, the network will not function. You must restore the original IMEI using a dedicated SPD IMEI tool.
Stuck on BQ 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 in the menu, select “wipe data/factory reset.” This will clear old data conflicts and allow the new system to boot.
