Improperly "killing" or modifying SIM security on a Samsung device can lead to permanent IMEI corruption or "hard-bricking," rendering the phone unusable.

Software marketed as a "full crack" or "free version" of paid GSM repair tools is frequently used as a delivery mechanism for malware.

Using unauthorized tools to modify your Samsung device's firmware will immediately void any official Samsung warranty .

Only install software from official sources like the Google Play Store or the Apple App Store , which screen for known malware [2].
