Recommendations
I understand you're looking to repair or restore the IMEI on a Sony Xperia XZ3. However, I must provide important context first:
Legality & Ethics:
Modifying or repairing an IMEI number is illegal in most countries unless you are the manufacturer, a licensed service center, or performing a legitimate repair using the device's original IMEI (e.g., after a mainboard replacement or software corruption). Falsifying an IMEI can lead to criminal charges.
Commercial repair boxes like Octoplus Sony Tool can repair IMEI in seconds via a paid subscription (~€20 for 3-day license). These tools bypass manual hex conversion and work even with the bootloader locked. If you repair phones frequently, this is your best bet.

, IMEI issues (such as a "null" or "0" IMEI) are typically caused by corrupted modem or EFS data. Official repairs involve software reflashing, while advanced repairs require entering specific diagnostic modes to write to the device's NVRAM. Method 1: Official Software Repair (Recommended)
If the IMEI is missing due to a minor software glitch, Sony’s official recovery tool can often restore functionality by reinstalling clean firmware. Tools Required: Xperia Companion (PC or macOS). Procedure : Install and open Xperia Companion on your computer. Select Software repair under "Manage your Xperia".
Follow the on-screen prompts; you will need to power off your
and hold the Volume Down button while connecting it to the PC. Note: This will wipe all user data. Method 2: Advanced Repair via Diagnostics Mode
For "null" or broken IMEIs that persist after a reset, you must enable Diagnostics Mode to use Qualcomm-specific tools. Enabling Diag Mode: Dial *#*#7378423#*#* to access the Service Menu.
If the menu does not offer a direct USB config, some technicians use ADB commands (requires Root): setprop sys.usb.config diag,adb.
Tools: Professional boxes like Miracle Box or software like QFIL/QPST are used to restore .qcn (Qualcomm Calibration Network) files which contain calibration and IMEI data. Method 3: SIM/Network Lock Issues SIM Network Lock - How to Unlock Sony XPERIA Phone

Losing or corrupting your Sony Xperia XZ3's IMEI (International Mobile Equipment Identity) can be a major headache, often leaving you with "No Service" or a device that cannot register on any network. Whether the issue arose from a failed software flash, a botched root attempt, or a hardware repair, restoring your 15-digit identity is critical for mobile connectivity. Understanding the "Invalid IMEI" Issue
The IMEI is a unique identifier stored in the device's NVRAM (Non-Volatile Random Access Memory). If this partition becomes corrupted, your phone displays "Invalid IMEI" or "IMEI 0" when you dial

In many regions, changing an IMEI to a number other than the original is illegal. Always restore the device to its original factory IMEI.

, your device will naturally have a new IMEI. If your phone was repaired by an authorized Sony center and the IMEI no longer matches your box, they should provide official documentation of the change to ensure your warranty remains valid.
If you are seeing "IMEI 0" after trying to install a custom ROM like PostmarketOS or Sailfish X, you likely need to flash the original "Trim Area" (TA) backup if you made one before unlocking your bootloader. [Tama][XZ3] SDM845 PostmarketOS on mailine kernel #799
