: The IMEI is typically "hard-coded" in a protected partition of the device's storage (NVRAM or EFS).
Some users flash a patched boot image that disables signature checks, then write a new IMEI. This (e.g., on KaiOS 1.x on the JioPhone). However, on newer devices (KaiOS 3.x), this triggers a hard brick because the bootloader checks the entire system integrity. Moreover, changing your IMEI to any number other than the original is a crime in many countries.
IMEI corruption rarely happens during normal everyday use. It is almost always the result of low-level software modifications or hardware failures:

Modifying system files on a KaiOS device, particularly when attempting to gain root access, can damage IMEI data.
In many countries, modifying, replacing, or repairing an IMEI number is illegal, especially if done to bypass cellular restrictions or hide a stolen device. KaiOS IMEI repair work should only be performed on your own device to restore functionality due to a software crash.

If the dialer code is disabled, you can use the Android Debug Bridge (ADB). With USB Debugging on, send the command: adb shell setprop sys.usb.config diag,adb .
If you want, I can provide a step-by-step repair checklist for a KaiOS device model (assume common Qualcomm chipset) — tell me the exact model and whether you have firmware/QCN backups. However, on newer devices (KaiOS 3
To perform an IMEI repair, a technician must force the device into a state where its inner diagnostic interfaces are exposed to a computer. 1. Qualcomm-Based KaiOS Devices
Interrupting the process of unlocking the bootloader or installing custom recovery images can corrupt NVRAM blocks.
