Extra-Tools SPD Diag Tool v1.0 Free Download | Read IMEI, Factory Reset, AT Command Tool
Extra-Tools SPD Diag Tool v1.0 is a free and lightweight Windows tool made for Spreadtrum and some MediaTek Android devices. This tool is mainly useful for mobile repairing work like reading IMEI, sending AT commands, rebooting devices, factory reset, power off, and turning on device backlight. The software is portable, simple to use, and works offline without activation.
Many mobile technicians need small tools for quick repair work because large flashing tools take too much time. This SPD Diag Tool helps in simple jobs where users only need basic repair options. The interface is clean and easy, so even beginners can understand the functions without confusion.
I personally tested this tool inside my repair shop on different SPD devices. One customer came with a phone that had no display light after flashing firmware. Another customer had missing VoLTE service after software repair. This tool helped me fix both issues easily using the backlight option and AT commands. Because of this, I always keep this tool inside my repair toolkit.
Why This Tool is Useful
Sometimes Android phones lose network settings after flashing or formatting. In many cases VoLTE stops working, the display light becomes black, or the device gets stuck. Using this tool, technicians can quickly send commands and repair some common software problems without using expensive professional tools.
The tool also supports sending custom AT commands. This is very helpful for IMS and VoLTE repair work on supported devices. Users can directly paste commands and send them to the device from the software window.

Personally Tested Repair Experience
Last week one customer came with a Spreadtrum phone after local flashing work. The phone was turning ON but the display light was not working properly. I connected the phone in Diag mode and used the “Turn On Backlight” option from this tool. Within seconds the display light started working normally again.
Another customer had a Jio SIM issue where VoLTE was completely missing after firmware flashing. Calls were switching to 2G and IMS registration was not active. I connected the phone using Diag mode and sent IMS related AT commands using this tool. After rebooting the phone, VoLTE icon started showing again.
Because the tool is small and portable, it becomes very useful for quick repair jobs in daily mobile service work.
