The Advan G-Tab (model 8001) is an 8-inch 4G LTE tablet from 2019, offering a large display for media and browsing. It is powered by the UNISOC SC9863A octa-core processor and runs on Android 8.0 Oreo. This guide provides the official stock firmware package to restore your device to its original factory software.
This firmware comes in the .cpb format, which requires a specific flashing utility called the YGDP (or QGDP) Tool. This process is the most effective solution for fixing major software issues, such as a bricked or dead tablet (mati total), a device stuck on the Advan logo, or other critical system errors.
Disclaimer: Flashing this stock ROM will completely erase all personal data from the tablet’s internal storage, including your apps, photos, contacts, and files. Please ensure you have backed up any important data before you begin.

Device-Specific Troubleshooting for Advan G-Tab (8001)
- YGDP Tool Does Not Detect Tablet: This is a driver issue. Ensure the Spreadtrum/UNISOC SCI drivers are installed correctly. Open the Windows Device Manager before connecting your tablet; when you connect it in flash mode, a “Spreadtrum” or “SCI” device should appear briefly under the “Ports (COM & LPT)” section.
- “Invalid CPB File” Error: This error in the YGDP tool means your downloaded firmware file is incomplete or corrupted. Download the file again and ensure you are loading the
.cpbfile, not the.ziparchive. - YGDP Tool Password: The flashing tool is password-protected. The most common default passwords are 9527 or 369. You will need to enter one of these to log in and use the tool.
- Restoring Performance: If your tablet has become slow or laggy over time, a full firmware flash is the best way to restore it to its original performance by installing a clean, factory-fresh version of Android.
FAQs
- Q1. My Advan G-Tab is stuck on the startup logo. Will this fix it?
- Yes. A “bootloop” is a classic sign of software corruption. Flashing this official
.cpbfirmware will completely overwrite the system and resolve the issue. - Q2. What is a
.cpbfile and why can’t I use the normal SPD Upgrade Tool? - A
.cpbfile is a different type of firmware package used by some manufacturers. It requires the YGDP Tool for installation and is not compatible with the standard SPD Upgrade Tool which uses.pacfiles. - Q3. Will this process remove the Google Account lock (FRP)?
- No. Flashing the stock firmware restores the OS but does not bypass Factory Reset Protection (FRP). After flashing, you will still be prompted to enter the login details of the last Google account synced to the tablet.
- Q4. The tool gives an error and fails to flash. What should I do?
- First, confirm your drivers are installed correctly. Second, use a high-quality USB cable and a main USB port on your computer (not a hub). Third, ensure the tablet’s battery has a sufficient charge before starting the process.
