The SPD Upgrade Tool is a windows application that allows users to flash or install .pac firmware (ROM) on their devices. This tool supports various devices running on the Spreadtrum/Unisoc chipset, making it a popular choice among users who want to upgrade their firmware.
On this page, we provide access to the latest version of the SPD Upgrade Tool, along with the FactoryDownload, ResearchDownload, and UpgradeDownload versions. These tools have lots of upgrades and features that make easier and more efficient the firmware updating process.

One of the key improvements in the latest version of the SPD Upgrade Tool is the optimized DL framework logger (tracer), which is similar to the one used by MediaTek SPFT. This improvement ensures that the firmware upgrade process is more efficient and reliable.
Additionally, the new version of the tool comes with RSA AuthenticationLib, which supports devices that require FDL authorization. This feature secures the privacy of the firmware upgrade operation and defends for unauthorized device access.
MES login exists, and a thread worker has also been added to the software, ensuring that the firmware packets are loaded without freezing. This improvement ensures that the firmware upgrade process is fast and smooth, even for large firmware files.
