Let’s break down the name:
In essence, the SPRD U2S Diag Driver is an unsigned, third-party driver that enables Windows to interface with Spreadtrum phones in “Diag” (or “Download”) mode. Unlike standard ADB or MTP drivers, this one bypasses normal Android security layers and gives direct access to the phone’s raw flash memory, NVRAM (where IMEI and radio calibration data lives), and boot partitions.
The 64-bit requirement is key. Since around 2017, Microsoft has strictly enforced driver signature enforcement on 64-bit versions of Windows. Any driver without a valid digital signature from Microsoft cannot be installed by default. The SPRD U2S Diag Driver is almost never properly signed.
Therefore, to install it on Windows 10 64-bit, users must:
