Q1. Why does this MediaTek phone use QGDP instead of SP Flash Tool?

For certain models, manufacturers like Advan chose to package the official factory firmware in the compressed .cpb format. This file type is not compatible with the standard SP Flash Tool (which uses scatter files) and requires the specific software it was designed for, which is the QGDP tool.

Q2. Can I use firmware from the regular Advan i5C or i5C Duo on this phone?

No. The i5C, i5C Duo, and i5C Lite are all different models. They may have different chipsets or other internal hardware. Using firmware from another model, even if the name is similar, will almost certainly brick your device. You must use the firmware that exactly matches your model name.

Q3. I lost my phone's IMEI number after flashing. How can I fix it?

Losing the IMEI is a risk if the flashing process is interrupted or done incorrectly. The QGDP process is generally safe for the IMEI, but if it is lost, it will need to be restored using a separate, advanced tool for MediaTek devices like Maui META. Your original IMEI can be found on the phone's box or under the battery.

Advan i5C Lite Stock Firmware (.cpb for QGDP)

The Advan i5C Lite is a 5.0-inch budget 4G LTE smartphone from the Indonesian brand Advan, released around 2017. Running on Android 7.0 Nougat, it was designed as an affordable device for everyday use. If your Advan i5C Lite is bricked, stuck in a bootloop, 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 firmware is packaged in the `.cpb` file format and must be installed using the QGDP Assembly Tool. This process is different from the more common SP Flash Tool and will completely erase all data on your device.

🔧 Device-Specific Troubleshooting

QGDP Tool Fails to Detect the Phone: This is the most common issue and is almost always driver-related. First, reinstall the MediaTek VCOM drivers. Second, follow the connection sequence precisely: power off the phone, click “Start” in the tool, press and hold Volume Down, and only then connect the USB cable.
“Invalid CPB File” Error in QGDP: This error means the firmware file is either corrupted or not compatible with your version of the QGDP tool. Try to download the firmware file again. If the problem persists, you may need a different version of the QGDP tool.
Flashing Fails Before Reaching 100%: A flash that stops midway can be caused by a faulty USB port or cable. Always use a high-quality cable and a reliable USB port (preferably a USB 2.0 port). If it consistently fails at the same percentage, it could indicate a failing eMMC (storage) chip on the phone, which is a hardware issue.
Stuck on Advan Logo After a Successful Flash: If the tool shows 100% but the device 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.
