The Advan I-Tab I7 Plus is a 7-inch 4G LTE tablet from 2017, offering voice calling and basic Android features. It is important to note that this model is powered by a Spreadtrum SC9832 processor, distinguishing it from other MediaTek-based tablets in Advan’s i7 series. This guide provides the official stock firmware 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 critical software issues such as a completely dead tablet (mati total), a device stuck on the Advan boot logo, or other system errors.
⚠️ Critical Warning: Data Erasure
Flashing this firmware is a complete reinstallation of the operating system. This process will permanently erase all of your personal information from the tablet, including:
- Photos, Videos, and Music
- Contacts and Call History
- SMS and App Messages
- All Installed Applications
Please back up your important files before proceeding. This action cannot be undone.

Device-Specific Troubleshooting for Advan I-Tab I7 Plus
- CRITICAL – Not for MediaTek i7 Models: The Advan i7 series is confusing, with many variants. This firmware is for the I-Tab I7 Plus which uses a Spreadtrum SC9832 chipset. It is NOT compatible with other models like the Advan i7 or i7A, which use MediaTek chipsets and require the SP Flash Tool. Flashing this firmware on the wrong model will brick it.
- YGDP Tool Does Not Detect Tablet: This is a driver issue. Ensure the 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.
FAQs
- Q1. My Advan tablet is dead, how do I know if this firmware is correct?
- This firmware is only for the I-Tab I7 Plus model with a Spreadtrum chipset. If you have an Advan i7A or i7, you likely have a MediaTek chipset and need a different firmware and the SP Flash Tool.
- 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 (FRP) lock?
- No. Flashing the stock firmware will restore the original operating system, but it does not bypass Factory Reset Protection (FRP). You will still need to enter the credentials of the last Google account that was synced to the device.
- 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.
