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)
- Downgrade the phone to an Android 15 firmware (factory image).
- Unlock the bootloader (required for flashing).
- Use the supplied Pixel IMEI repair tool (the ZIP contains
khan2.exe) to produce a modifieddeviceinfo.img. - Flash the modified
deviceinfo.imgusing fastboot. - 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.
- On the phone, go to Settings → About phone → Build number and tap it 7 times to enable Developer Options.
- Open Settings → System → Developer options and enable:
OEM unlockingUSB debugging
- Connect the phone to your PC with a USB cable.
- Open Command Prompt in your platform-tools folder and run:
adb reboot bootloader - Then run:
Use the phone's volume and power buttons to confirm the unlock. This will factory-reset the device.fastboot flashing unlock
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.
- Download the correct Android 15 factory image for your exact Pixel model from the official source.
- Extract the firmware zip on your PC.
- Boot the phone into Fastboot Mode (Power + Volume Down) and connect to PC.
- Run the provided flash script, for example:
flash-all.bat - 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.
- Extract the ZIP package anywhere on your PC.
- Open the extracted folder. You will find an executable named
khan2.exeand a folder namedmodel(or similar) containing subfolders forPixel 6,Pixel 6a, andPixel 6 Pro. - Double-click
khan2.exeto open the tool. - Choose the correct button for your device:
Process Pixel 6Process Pixel 6aProcess Pixel 6 Pro
- Enter your original IMEI values into the fields labeled New IMEI 1 and New IMEI 2 (if dual-SIM, provide both).
- Click Replace IMEIs. The tool will modify the
deviceinfo.imginside that model's folder.
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.
- Copy the modified
deviceinfo.imginto your platform-tools folder (or the folder where your ADB/Fastboot tools are). - Boot your phone into Fastboot Mode and connect it to the PC.
- Open Command Prompt in the same folder and run:
fastboot flash deviceinfo deviceinfo.img fastboot reboot - Wait for the device to reboot fully.
Step 5 — Verify IMEI and Network
- Open Settings → About phone → IMEI information and confirm your IMEI(s) are correct.
- Insert SIM card(s) if removed and check for signal. Toggle Airplane Mode on/off if needed.
- 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.
Summary — What to Expect
This method fixes IMEI and network issues caused by firmware corruption in many cases. The steps are:
- Backup data and prepare tools.
- Unlock bootloader (will wipe device).
- Downgrade to Android 15 factory image.
- Run
khan2.exeto produce a modifieddeviceinfo.imgwith your IMEI(s). - Flash
deviceinfo.imgvia 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.
