The SC7715 IMEI Tool is a Windows-based utility that communicates directly with the SC7715 chipset via the phone’s diagnostic (Diag) port. It allows users to read, write, and repair IMEI numbers without needing to reflash the entire firmware.
In the world of Android smartphone repair, few things are as frustrating as a device losing its network connectivity. For technicians and advanced hobbyists working with entry-level Android devices—often powered by the Spreadtrum (SPRD) SC7715 chipset—the "Invalid IMEI" or "Null IMEI" error is a common hurdle.
This is where the SC7715 IMEI Tool comes into play. Unlike the automated "one-click" tools available for popular brands like Samsung or Xiaomi, repairing the IMEI on legacy Spreadtrum chipsets often requires a specific, file-based approach.
Here is a breakdown of the tool, the risks involved, and the general procedure for restoration.
The SC7715 is a legacy ARM11 chipset found in many budget smartphones and feature phones running Android 4.x to Android 6.0. Because these devices utilize older partition structures, they do not always support modern NV (Non-Volatile) repair methods used on newer SPRD chipsets like the SC9832 or Unisoc T606.

Instead, the SC7715 IMEI Tool typically functions by writing Bin/Modem files directly to the device’s flash memory.
In the sprawling ecosystem of mobile devices, Spreadtrum (now UNISOC) processors power millions of affordable smartphones and feature phones globally. Among these, the SC7715 chipset is a common workhorse found in entry-level 3G and 4G devices from brands like itel, Tecno, Spice, and various white-label manufacturers.
However, a common nightmare for repair technicians and hobbyists alike is the sudden loss of IMEI numbers after a firmware flash, factory reset, or software glitch. Without a valid IMEI, your phone becomes a glorified Wi-Fi tablet—unable to make calls, send texts, or use mobile data.
Enter the SC7715 IMEI Tool. This specialized piece of software is the industry standard for rewriting, repairing, and backing up IMEI numbers on devices powered by the Spreadtrum SC7715 chipset. The SC7715 IMEI Tool is a Windows-based utility

The SC7715 is a baseband processor developed by Spreadtrum Communications (now UNISOC). It is a highly integrated 3G/4G modem that handles all radio frequency (RF) communications on a device. Unlike Qualcomm or MediaTek chips, Spreadtrum processors have a unique method of storing critical device data, including IMEI numbers, calibration data, and Wi-Fi MAC addresses in a dedicated partition called NVRAM (Non-Volatile Random Access Memory).
