What it is

The SPRD U2S Diag Reset Tool is a Windows utility used to interact with Spreadtrum/Unisoc (SPRD/UNISOC) chipset-based Android devices. It provides functions such as entering diagnostic mode, reading/writing NV (non-volatile) items, removing FRP (Factory Reset Protection), IMEI repair, format/reset partitions, and other low-level maintenance and repair operations.

When a phone is connected in this mode, it appears as a COM port (often identified as SPRD U2S Diag COM3 or COM5) in the Windows Device Manager. This mode allows the computer to communicate directly with the device's diagnostic interface to perform low-level operations like firmware flashing, IMEI repair, or security resets.
