Q1. Why does this MediaTek tablet use QGDP instead of the normal SP Flash Tool?

For some models, manufacturers like Advan package the official firmware in a compressed .cpb format instead of the standard scatter file format. This .cpb file is not compatible with SP Flash Tool and requires the specific factory tool it was designed for, which in this case is QGDP.

Q2. This firmware is for the 1GB RAM model. Will it work on a 2GB RAM variant?

It is not recommended. While the core chipset is the same, using firmware designed for a different RAM configuration can lead to instability, boot failures, or other unexpected issues. It is always safest to use firmware that exactly matches your device's hardware specifications.

Q3. What is the difference between the Advan i7U and i7K?

Both are very similar 7-inch tablets with the same MT8321 chipset. The i7U is a slightly different or newer revision. Despite their similarities, their firmwares are not interchangeable. You must use the specific firmware for your model to avoid bricking the device.

Advan i7U Stock Firmware (.cpb for QGDP Tool)

The Advan i7U is a 7-inch budget tablet from Indonesian manufacturer Advan, offering 3G connectivity and running Android 7.0 Nougat. It’s a capable device for basic media and communication tasks. If your tablet has become bricked, is stuck on the Advan logo, or is suffering from other critical software failures, flashing the official stock firmware is the most effective solution to restore it to its original state.

Important Note: This firmware is provided in the `.cpb` format and must be installed using the QGDP Assembly Tool, not the more common SP Flash Tool. This process will completely erase all data from your device.

🔧 Device-Specific Troubleshooting

QGDP Tool Fails to Detect the Tablet: This is the most common problem and is almost always related to drivers. Ensure the MediaTek VCOM drivers are correctly installed. Follow the connection sequence precisely: power off the tablet, click “Start” in the tool, press and hold Volume Down, then connect the USB cable.
“Invalid CPB File” Error in QGDP: If the tool reports that the file is invalid, your download may have been corrupted. Download the firmware file again. If the problem persists, you may need a different version of the QGDP tool that is compatible with this specific firmware package.
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 on the back of a desktop PC). If it consistently fails at the same percentage, it could indicate a failing eMMC (storage) chip on the tablet, which is a hardware issue.
Stuck on Advan Logo After Flashing: If the flash completes successfully but the tablet won’t boot, a factory reset is necessary. Power off the device, then boot into recovery mode (usually by holding Power + Volume Up). In the recovery menu, select “wipe data/factory reset” to clear any old data and allow the new system to boot.
