After rebooting with your spoofed IMEI:
*#06#adb shell
su
service call iphonesubinfo 4 # Query IMEI via RIL
Critical test: Place a call or use mobile data. If the IMEI is completely invalid (wrong checksum, TAC prefix that doesn’t match hardware), the network will reject your device. Your phone will say "Emergency Calls Only."
The International Mobile Equipment Identity (IMEI) is a 15-digit unique identifier assigned to every mobile phone. Think of it as a social security number for your device. Network carriers, law enforcement, and device manufacturers use it to track a phone’s legitimacy, blacklist stolen devices, and manage network access. change imei with magisk
There are legitimate reasons to modify or spoof an IMEI:
However, because IMEI manipulation is illegal in many jurisdictions (e.g., the UK under the Wireless Telegraphy Act, and many US states under anti-fraud statutes), this guide is strictly for educational purposes on rooted Android devices using Magisk. Do not use this to obscure a stolen device or evade law enforcement. The Definitive Guide to Changing IMEI with Magisk:
Let’s cut to the chase: changing your IMEI isn’t something you do for fun. It’s either a desperate measure (blacklisted phone), a privacy move, or something shadier. But with Magisk, the root method that’s become the gold standard for systemless modifications, the process is more elegant than the old, messy Xposed or firmware-hacking days.
| Problem | Likely Cause | Solution |
|---------|--------------|----------|
| IMEI reverts after reboot | persist. properties not saved; or late service override | Move script to late_start service in Magisk |
| *#06# shows old IMEI | RIL ignoring setprop | Use LSposed method or modify build.prop via MagiskHide Props with ro.ril.imei |
| No network registration | Spoofed IMEI is invalid or blacklisted elsewhere | Restore original IMEI via module disable |
| SafetyNet/Play Integrity fails | Google detects property tampering | Use MagiskHide + DenyList, exclude telephony apps |
| After module uninstall, phone shows "Invalid IMEI" | EFS corruption? Very unlikely with Magisk – but try restoring EFS backup from TWRP | Reflash stock firmware without wiping data | Check system dialog : *#06# Check via ADB
While Magisk provides the framework to spoof an IMEI to Android applications via systemless hooks, it cannot easily overwrite the hardware identifier recognized by cellular networks. The process of permanently altering an IMEI is complex, illegal in most jurisdictions, and carries a high probability of destroying the device's ability to make calls.
Recommendation: If your IMEI has been blacklisted incorrectly, contact your carrier or the manufacturer to resolve the issue through legal channels. Do not attempt to modify hardware identifiers.
