This section collects official and community-tested drivers for smartphones powered by Spreadtrum/Unisoc chipsets. You’ll find SPD USB VCOM (preloader) drivers for flashing tools, CDC/ADB drivers for file transfer and debugging, USB serial/modem drivers for network tethering, and specific INF packages used by ResearchDownload/UpgradeDownload utilities. Files include installers and standalone INF/ZIP archives.
Downloads are provided as direct links with checksums; each package includes a short install guide. Typical installation: extract the archive, connect the phone in the required mode (Preloader/Factory/ADB), open Device Manager, choose “Update driver” → “Browse” and point to the extracted INF. Windows XP through Windows 11 (32/64-bit) are supported; 64-bit systems may require temporarily disabling driver signature enforcement. If the device is not recognized, follow the included troubleshooting steps (reinstall, use correct USB mode, ensure proper cable/port). Use these drivers when flashing firmware, enabling ADB, or restoring connectivity on Spreadtrum-based handsets.
