The Advan X7 Pro is a 7-inch 4G LTE tablet released in 2019 as part of Advan’s popular X7 series. It is powered by a UNISOC SC9850 processor and runs on Android 8.1 Oreo (Go Edition), optimized for its 1GB of RAM. 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 the specific YGDP (or QGDP) Tool for flashing. This process is the most reliable solution for fixing major software issues, such as a completely dead tablet (mati total), a device stuck on the Advan boot logo, or other critical system errors.
Disclaimer: Flashing this stock ROM will completely erase all data from your tablet’s internal storage, including your apps, contacts, photos, and files. Please ensure you have backed up any important data before you begin.

How to Flash Stock Firmware
To restore your Advan X7 Pro, you must use the YGDP Tool. First, install the UNISOC/Spreadtrum drivers on your PC. Open the YGDP Tool, enter the password (e.g., ‘9527’ or ‘369’), and use the “Config” menu to load the .cpb firmware file. Click “Start” on the main screen. Power off your tablet completely. Press and hold the Volume Down key while connecting the tablet to your PC with a USB cable to begin the flashing process.

Device-Specific Troubleshooting for Advan X7 Pro
- CRITICAL – For X7 Pro ONLY: This firmware is exclusively for the Advan X7 Pro (UNISOC SC9850). It is NOT compatible with the older Advan X7 (MT8382) or Advan X7 Plus (MT6580), which use MediaTek chipsets and different flashing tools. 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.
- 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 Android Go Performance: The Advan X7 Pro runs the lightweight Android Go Edition. If the tablet has become slow or unresponsive, a full firmware flash is the best way to restore its original performance by removing all software clutter and providing a clean installation of the OS.
FAQs
- Q1. My Advan X7 Pro is dead (mati total). Will this firmware fix it?
- Yes. If the cause of the dead device is corrupted software (a “hard brick”), then flashing this official
.cpbfirmware is the standard procedure to unbrick it and restore it to working condition. - Q2. Can I use this firmware on my old Advan X7 or X7 Plus?
- No, absolutely not. The X7 Pro uses a completely different chipset and software package from its predecessors. This firmware will brick the older models.
- Q3. The flash tool asks for a password. What do I enter?
- The most common default passwords for the YGDP Tool are ‘9527’ and ‘369’. Try one of those to log in.
- Q4. 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.
