Confirming the BGA (Ball Grid Array) surface-mount connections are working properly after using a hot-air rework station to replace a damaged chip. Step-by-Step Installation Guide for Windows 10 & 11
Windows 10 and 11 users should disable signature enforcement before installation to prevent the "Driver could not start" error. Use the Device Manager: Instead of just running an .exe, manually point the Device Manager to the extracted driver folder (usually containing sci_usb_serial.inf Select the UMS9117 Profile: When using service tools, specifically select the UMS9117 (Nokia line)

Finding official drivers for a specific legacy chip like the UMS9117 can be challenging. However, due to the widespread use of Unisoc (formerly Spreadtrum) chipsets, a few reliable methods exist:
Use a high-quality data cable; plug directly into a motherboard port (avoid USB hubs). Normal behavior for UMS9117 bootloader.
This comprehensive guide explores why your Unisoc UMS9117 device is running hot, how drivers impact thermal performance, and the exact steps you can take to cool down your device. Understanding the Unisoc UMS9117 Architecture : Requires explicit low-level USB drivers to translate
If you are encountering this issue, follow these steps in order to diagnose and resolve the problem. 1. Perform a Forced Restart Sometimes a temporary process glitch causes the heat.
The thermistor divider network had a cracked resistor (47kΩ pull-up). After replacing R621 (near battery connector), the driver reported normal 38°C.
