On Qualcomm devices, the IMEI is stored in the EFS partition (/dev/block/bootdevice/by-name/efs). On MediaTek, it's in /dev/nvram. On Exynos (Samsung), it’s in /efs.
Magisk doesn’t overwrite these partitions. Instead, it intercepts requests for the IMEI at the RIL (Radio Interface Layer) level. The RIL is the software bridge between Android’s telephony service and the modem firmware.
A Magisk module for IMEI spoofing works by:
The most popular and practical approach for modern Android (10-14) is using a dedicated Magisk module called "IMEI Changer" (by Magisk-Modules-Repo) or the more robust "MagiskHide Props Config" combined with custom boot scripts.
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. change imei with magisk
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.
Here’s an interesting, critical, and practical review of changing IMEI with Magisk — written in a style suitable for a tech blog or forum post.
Because Magisk works systemlessly:
If you used LSposed, simply deactivate the module in LSposed Manager and reboot. On Qualcomm devices, the IMEI is stored in
No permanent change is made – that’s the beauty of Magisk.
After rebooting with your spoofed IMEI:
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."
For devices where property override doesn’t work, you need to hook Java methods inside TelephonyManager. The most popular and practical approach for modern
This method is more reliable but also easier for malware to intercept – use only trusted open-source LSposed modules.

If your goal is privacy or bypassing carrier tracking, consider these instead:
| 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 |
