Pros:
Cons:
Q1: Can I use the 2021 SC7715 tool on SC7700 or SC9820?
No. It is strictly for SC7715. Attempting may corrupt the modem firmware.
Q2: Does the tool work on 64-bit Windows 11?
Yes, with proper administration rights and legacy driver mode enabled.
Q3: My antivirus flags it as a virus. Is it safe?
Some security software detects IMEI writers as "riskware" because they modify device identifiers. The genuine 2021 top version is safe, but always download from trusted GSM forums.
Q4: Can I write IMEI without root?
Yes. The tool uses low-level DIAG port communication, independent of Android OS.
Q5: Why does it show "IMEI write success" but still null on the phone?
Reboot the phone twice. If still null, the NVRAM partition is bad—use the tool’s “Format NVRAM” option (warning: erases calibration data).
