Prerequisites: Your Pre-Flash Checklist ✅

To ensure a smooth and successful flashing process, please complete these essential steps first.

1. Backup Your Data: Flashing will completely erase all personal data (photos, apps, contacts). Back up everything important to a computer or cloud storage.
2. Charge the Tablet: Make sure your Digma Citi 10 E402 has at least 60% battery to prevent it from shutting down unexpectedly.
3. Install UNISOC/SPD Drivers: For your computer to detect the tablet correctly, you must install the right drivers. You can download the generic SPD Driver package and install it on your Windows PC.
4. Download SPD Upgrade Tool: This is the software used to flash .pac firmware files. Download the latest version from a trusted source.

Frequently Asked Questions (FAQ)

What is a .pac file?
A .pac file is a packed firmware file that contains all the necessary partitions (system, boot, recovery, etc.) for a UNISOC/Spreadtrum device. The SPD Upgrade Tool reads this single file to flash the entire system.

Will this update my Android version?
This firmware package will install Android 10. It is a clean installation, not an OTA update. If you are already on a newer version, this will be a downgrade.

The tool is not detecting my tablet. What should I do?
This is almost always a driver issue. Ensure you have installed the SPD drivers correctly. Try uninstalling and reinstalling them, restarting your PC, and using a different USB port and a high-quality USB cable.
