Before using advanced tools, verify if the IMEI is actually missing or if there is just a network glitch.

Check IMEI: Dial *#06# in the Phone app to see if the number displays correctly.

Software Repair: Use the Sony Xperia Companion tool on a PC. Select "Software Repair" to reinstall the official firmware, which can sometimes restore corrupted baseband files.

Forced Restart: Simultaneously hold the Power and Volume Up buttons until the device vibrates to clear temporary system glitches. 2. Specialized Repair Tools (Technical)

If the IMEI is null or invalid after a custom ROM installation or a failed flash, technicians often use specific service tools. These usually require a Windows PC and a USB cable. repair imei sony xz3

Sony Mobile Flasher (Flashtool): Used to manually flash the official .ftf firmware files. Reflashing the specific "Baseband" or "Modem" files can sometimes fix IMEI issues.

QFIL (Qualcomm Flash Image Loader): Since the XZ3 uses a Qualcomm Snapdragon 845 chipset, QFIL can be used to restore the QCN file (Qualcomm Calibration Network). This file contains the device's unique network and IMEI parameters.

Paid Service Tools: Professional tools like Chimera Tool or Octoplus Box support IMEI repair for specific Sony models, though these typically require a paid license or hardware dongle. 3. Check for Network Blacklisting

If the IMEI is visible but you have no service, the device might be blacklisted by carriers rather than having a "broken" IMEI.

Check the status of your device on a public IMEI Checker to see if it has been reported lost or stolen.

If the device was purchased second-hand and is blacklisted, you must contact the original carrier to resolve the billing or ownership issue.

Note: If your mobile data is simply not working but the IMEI is present, you may just need to update your APN settings for your specific carrier.

If the EFS partition is physically damaged (bad NAND blocks), no software repair will work. A replacement motherboard for XZ3 costs around $80–120 on eBay. After swapping, the IMEI will match the new board—so re-solder the old SIM slot’s chip if needed to retain legality.

It is crucial to note the line between repair and fraud. Restoring a phone’s original IMEI is a legitimate repair, often saving a device from the landfill. However, "Repairing" an IMEI by changing it to a different number (often stolen from another device) is illegal in most jurisdictions. A true repair aims to restore the factory identity, not fabricate a new one.

A common pitfall in the XZ3 repair community is the "Null IMEI" fix. Many users attempt to use generic Qualcomm tools (like QFIL) to flash the prog_emmc_firehose_Sdm845 programmer.

While this can successfully unbrick the phone, it often fails to rewrite the security partitions (EFS/Modemst1/Modemst2) if the device is in a "secure boot" state. This results in a phone that boots perfectly but still cannot register on a network. The challenge isn't making the phone turn on; it's convincing the modem that it has a license to broadcast.
