    • The SC7715 IMEI Tool is a lightweight, portable application designed specifically for Spreadtrum SC7715-based devices (e.g., ZTE, Infinix, Tecno, and various Chinese OEM models). Unlike generic IMEI writers, this tool communicates directly with the SC7715’s engineering firmware via the Diag (Diagnostic) port.

    Before presenting the fixed solution, it is essential to catalog typical failure modes:

    | Error Message / Symptom | Underlying Cause | |-------------------------|------------------| | Device not found | Driver not installed, device in wrong mode (normal boot vs. download) | | Download failed – timeout | Windows USB selective suspend, poor cable, or unstable COM port | | IMEI write failed – NAK | NV region locked; need to unlock using AT+SPNVM command first | | Checksum error | Tool version mismatch with firmware version on SC7715 | | Port open error | Another application (e.g., modemu, SPD Upgrade Tool) holds COM port |

    Q: Does this tool work on SC7731, SC9832, or SC9850?
    A: Partially. The fixed version was patched specifically for SC7715. For other chips, use the Unisoc IMEI Writer (separate tool).

    Q: My phone doesn't enter diagnostic mode. What do I do?
    A: Dial *#*#3646633#*#* (Engineer Mode) → Log and Debugging → USB Port Settings → Set to "AT+ADB+LOG". Then reconnect.

    Q: Can I generate a completely new IMEI?
    A: Technically yes, but only if you own the device. Use an IMEI generator responsibly – but restoring the original IMEI is always safest and most legal.

    Q: I downloaded the tool but the EXE is flagged as virus.
    A: Spreadtrum tools often trigger false positives because they modify low-level system partitions. Add an exception in Windows Defender. However, always verify the SHA-256 hash we provided.
