Repair IMEI Sony XZ3 Report

Introduction

The Sony XZ3 is a high-end smartphone released in 2018, known for its impressive camera and sleek design. However, like any electronic device, it can be prone to issues, including problems with its IMEI (International Mobile Equipment Identity) number. This report aims to provide an overview of the process and methods used to repair an IMEI on a Sony XZ3 device.

What is IMEI and why does it need repair? repair imei sony xz3

The IMEI is a unique 15-digit serial number assigned to each mobile device, used to identify and authenticate the device on a cellular network. If the IMEI is damaged, corrupted, or altered, the device may not be able to connect to the network, make calls, or send texts. IMEI repair is necessary in cases where the IMEI is:

  1. Null or Unknown: The IMEI is empty or displayed as "Unknown" on the device.
  2. Changed or Altered: The IMEI has been intentionally or unintentionally modified, causing network connectivity issues.
  3. Corrupted: The IMEI is damaged due to software or hardware issues, preventing the device from functioning properly.

Step 2: Enable Diag Mode on Sony XZ3

Qualcomm-based Xperias hide a diagnostic port. To write a repair, you need access to Diag Mode.

  1. Enable Developer Options (tap build number 7 times).
  2. Enable USB Debugging.
  3. On your PC, open a command prompt and type: 
    adb shell
su
setprop sys.usb.config diag,adb
    (If you don’t have root, you’ll need to temporarily boot a patched kernel. Use Magisk-patched boot image for XZ3.)
  4. After running the command, your PC will detect a new “Qualcomm HS-USB Diagnostics” port. Note the COM port number (e.g., COM5).

No root? You can try using a custom recovery like TWRP with the diag_enable script, but root is strongly preferred for IMEI repair.

Method B: Restore from a Clean QCN File

If manual writing fails, find a clean QCN from a working XZ3 of the exact same model (e.g., H8416 to H8416, not cross-model). Using a hex editor (HxD), paste your original IMEI into the QCN at offset 0x34A00 (varies by firmware). Then, restore that modified QCN using QPST Software Download → Restore tab. Null or Unknown : The IMEI is empty

If You Need to Restore the Original IMEI After Software Corruption

If your XZ3 shows "Invalid IMEI," "Null IMEI," or no signal after flashing or a failed update, here are legitimate steps:

Method A: Direct Write (For dual-IMEI models – XZ3 Dual)

The XZ3 Dual (model H9436, H9493) has two IMEIs.

How to convert your IMEI:
Take your 15-digit IMEI: 123456789012345
Remove the last digit (checksum): 12345678901234
Split it into hex pairs: 12 34 56 78 90 12 34 then reverse the order. On QXDM, you input it reversed.
Better yet: Use IMEI Converter tool (search online) to get the correct hex string.

In NV Browser:

  1. Double-click 550 (or 1943 for second IMEI).
  2. Select Hex input.
  3. Type the converted hex value.
  4. Click Write.
