If your Google Pixel 6, 6A or 6 Pro shows IMEI 000000000000000 or you have lost cellular service after an update, this guide walks you through a safe, free method to recover IMEI and restore network connectivity. The process includes downgrading to Android 15 firmware, unlocking the bootloader, flashing a modified deviceinfo.img, and restoring the IMEI. Follow carefully — a wrong step can erase data or brick the device.

Why IMEI / Network Problems Happen

System updates can sometimes corrupt or overwrite the phone's IMEI storage area (often controlled by deviceinfo.img or similar partitions). When IMEI data becomes invalid or null, the phone will show "No Service", "Emergency Calls Only", or an IMEI of all zeros.

Overview of the Fix (What you'll do)

  1. Downgrade the phone to an Android 15 firmware (factory image).
  2. Unlock the bootloader (required for flashing).
  3. Use the supplied Pixel IMEI repair tool (the ZIP contains khan2.exe) to produce a modified deviceinfo.img.
  4. Flash the modified deviceinfo.img using fastboot.
  5. Reboot and verify IMEI / network.

Important Preparations

  • Backup your data. Unlocking the bootloader will wipe the device.
  • Use an official firmware image for your exact model (Pixel 6 / 6A / 6 Pro).
  • Have a working USB cable and a Windows PC (the provided tool includes an .exe).
  • Battery should be at least 50%.

Step 1 — Unlock Bootloader (Required)

Unlocking the bootloader is necessary to flash system partitions and custom images.

  1. On the phone, go to Settings → About phone → Build number and tap it 7 times to enable Developer Options.
  2. Open Settings → System → Developer options and enable:
    • OEM unlocking
    • USB debugging
  3. Connect the phone to your PC with a USB cable.
  4. Open Command Prompt in your platform-tools folder and run:
    adb reboot bootloader
  5. Then run:
    fastboot flashing unlock
    Use the phone's volume and power buttons to confirm the unlock. This will factory-reset the device.
Note: Unlocking the bootloader factory-resets the phone. Make sure you backed up contacts, photos, and any important files.

Step 2 — Flash Android 15 Factory Image (Downgrade)

Downgrading to Android 15 helps remove incompatibilities introduced by newer updates and increases the chance of successful IMEI repair.

  1. Download the correct Android 15 factory image for your exact Pixel model from the official source.
  2. Extract the firmware zip on your PC.
  3. Boot the phone into Fastboot Mode (Power + Volume Down) and connect to PC.
  4. Run the provided flash script, for example:
    flash-all.bat
  5. Wait for the flashing process to complete and for the device to reboot.

Tip: After flashing Android 15, about 50% of IMEI / network problems are often resolved immediately. If IMEI is still null or zeroed, continue to the next steps.

Step 3 — Use the Pixel IMEI Repair Tool (khan2.exe)

The ZIP you downloaded contains a tool that edits the deviceinfo.img for the specific Pixel model.

  1. Extract the ZIP package anywhere on your PC.
  2. Open the extracted folder. You will find an executable named khan2.exe and a folder named model (or similar) containing subfolders for Pixel 6, Pixel 6a, and Pixel 6 Pro.
  3. Double-click khan2.exe to open the tool.
  4. Choose the correct button for your device:
    • Process Pixel 6
    • Process Pixel 6a
    • Process Pixel 6 Pro
  5. Enter your original IMEI values into the fields labeled New IMEI 1 and New IMEI 2 (if dual-SIM, provide both).
  6. Click Replace IMEIs. The tool will modify the deviceinfo.img inside that model's folder.
Where to find your IMEI? IMEI is printed on the original box, SIM tray, or you can check old receipts. Never invent or use another device's IMEI — always use the correct original IMEI(s).

Step 4 — Flash Modified deviceinfo.img via Fastboot

After the tool creates the modified deviceinfo.img, use fastboot to flash it back to the phone.

  1. Copy the modified deviceinfo.img into your platform-tools folder (or the folder where your ADB/Fastboot tools are).
  2. Boot your phone into Fastboot Mode and connect it to the PC.
  3. Open Command Prompt in the same folder and run:
    fastboot flash deviceinfo deviceinfo.img
    fastboot reboot
  4. Wait for the device to reboot fully.

Step 5 — Verify IMEI and Network

  1. Open Settings → About phone → IMEI information and confirm your IMEI(s) are correct.
  2. Insert SIM card(s) if removed and check for signal. Toggle Airplane Mode on/off if needed.
  3. If the network does not return immediately, restart the phone once more and test.

Common Issues & Troubleshooting

  • Fastboot not detecting phone: Reinstall platform-tools, check USB drivers, try another USB port or cable.
  • Wrong firmware: Flashing the incorrect factory image will fail or cause problems — ensure model names match exactly.
  • Tool fails to run: Some antivirus may block the .exe — temporarily allow the file or run as Administrator (only if you trust the source).
  • IMEI still not visible: Re-check deviceinfo.img was correctly replaced and fastboot flash completed without errors.

Safety & Legality

Restoring your original IMEI on a phone you own is generally legal. Do not attempt to change IMEIs to numbers that do not belong to your device. Using someone else's IMEI or changing IMEIs for fraudulent purposes is illegal in many jurisdictions. Always use official or original IMEI values for the device.

Warning: This guide involves unlocking the bootloader and flashing system partitions. These actions may void warranty and will erase data. Proceed only if you understand the risks and have backups.

Summary — What to Expect

This method fixes IMEI and network issues caused by firmware corruption in many cases. The steps are:

  1. Backup data and prepare tools.
  2. Unlock bootloader (will wipe device).
  3. Downgrade to Android 15 factory image.
  4. Run khan2.exe to produce a modified deviceinfo.img with your IMEI(s).
  5. Flash deviceinfo.img via fastboot and reboot.

Approximately half of affected devices regain IMEI/network simply after the downgrade step. If not, using the IMEI repair tool + flashing modified deviceinfo.img typically restores IMEI and network connectivity.

Notes

If you follow each step carefully, most Pixel 6 series phones with IMEI 000000000000000 or "No Network" after an update will be recoverable. If the problem persists after these steps, the fault may be deeper (hardware/baseband chip damage) and you should consult an authorized service center.
