1. Why Does Pixel 6 Series IMEI Become 0?

The Google Pixel 6 series (oriole, bluejay, raven) runs on the Google Tensor chipset (first-generation Tensor G1), which handles baseband and IMEI data differently than Qualcomm devices. When you perform certain operations, the CPID (Chipset Persistent ID) and NV data partitions can become corrupted or overwritten.

Common triggers for IMEI 0:

Symptoms of IMEI 0 / null IMEI on Pixel 6, 6A, and 6 Pro:

• IMEI 0 or Null IMEI when dialing *#06#
• No Signal or Emergency Calls Only in status bar
• Baseband Unknown in Settings → About Phone
• Network registration failures (cannot connect to any carrier)
• Persistent “No Service” even in areas with strong signal

Temporary fixes exist, but they break the moment you update your phone or flash new firmware. The method below fixes the root cause permanently on all three Pixel 6 series models.

2. What Makes This Fix Permanent?

Unlike traditional IMEI repair tools that write the IMEI to a volatile partition (which gets overwritten during OTA updates), this method uses the Google Pixel Technicians Toolkit V3 to:

Once done, you can safely:

• Relock your bootloader
• Use banking apps (Google Pay, WhatsApp, etc.)
• Install any OTA update without losing IMEI
• Flash full factory firmware without fear

3. Supported Devices (oriole, bluejay, raven) & Android Versions

Supported Devices (Pixel 6 Series):

How to identify your device codename:

• Settings → About Phone → Regulatory Labels
• Look for model number: GR1YH (oriole), GX7AS (bluejay), or GF5KQ (raven)
• Or check the sticker on your phone’s original box

Supported Software Versions:

This Fix Resolves (All Three Models):

• Pixel 6 (oriole) IMEI 0 / null IMEI
• Pixel 6A (bluejay) no signal after OTA update
• Pixel 6 Pro (raven) lost IMEI after firmware flash
• No baseband after rooting attempt on any Pixel 6 series device
• Network unlock failures caused by CPID corruption
• “Invalid IMEI” error in modem logs

4. Prerequisites: What You Need

Before starting, gather these files and tools:

⛔ CRITICAL WARNING: Unlocking the bootloader (required for this fix) will wipe ALL data on your phone regardless of whether you have an oriole, bluejay, or raven. Back up everything important (photos, contacts, documents, app data) before you begin.

5. Step-by-Step: Permanent Pixel 6 Series IMEI 0 Fix

Follow these steps carefully. Do not skip any step. These steps work identically for Pixel 6 (oriole), Pixel 6A (bluejay), and Pixel 6 Pro (raven).

Step 1: Download All Required Files

Before touching your phone, download:

• Stock firmware for your exact model: oriole (Pixel 6), bluejay (Pixel 6A), or raven (Pixel 6 Pro)
• Magisk APK (latest version)
• Google Pixel Technicians Toolkit V3 installer
• Android USB Drivers

Verify the stock firmware matches your device codename. Flashing oriole firmware on a bluejay or raven will brick your phone.

Step 2: Extract and Patch Boot Image

On your PC:

• Extract the downloaded stock firmware ZIP file
• Locate the boot.img file inside the extracted folder
• Copy boot.img to your phone’s internal storage

On your phone (oriole, bluejay, or raven):

• Install Magisk APK (you may need to enable “Install from unknown sources”)
• Open Magisk app
• Click Install → Select and Patch a File
• Navigate to the boot.img file you copied
• Wait for Magisk to patch the file
• Copy the generated magisk_patched.img back to your PC

The patched image will be saved in the Download folder on your phone.

Step 3: Install and Activate Google Pixel Technicians Toolkit V3

• Run the toolkit installer as Administrator
• Launch the toolkit from desktop or Start Menu
• Visit the toolkit download page for the daily activation token
• Copy and paste the token into the toolkit
• Click VERIFY to activate

The toolkit will show the main interface with all tabs (Device Management, Flash, Tensor CPID, Repair, etc.).

Step 4: Flash Stock Firmware (First Time)

Put your Pixel 6 series phone in bootloader mode:

• Power off your phone completely
• Press and hold Volume Down + Power buttons simultaneously
• Release when you see the fastboot screen (green start arrow)

This works the same on oriole, bluejay, and raven.

Connect and flash:

• Connect phone to PC using original USB cable
• In the toolkit, go to the Flash Tab
• Click Flash Factory Firmware
• Select the stock firmware folder you downloaded (must match your device codename)
• Click Execute

The flashing process takes 5-10 minutes. Do not disconnect the phone.

Note: If your bootloader is locked, the toolkit will offer to unlock it. Click Yes. This will wipe your data. This is necessary for the fix on all Pixel 6 series devices.

Step 5: Root with Magisk (Temporary)

After stock firmware flash completes, the phone may reboot. Put it back in bootloader mode.

Flash the patched boot image:

• In the toolkit, go to Flash Tab → Custom Partition
• Select Boot partition
• Click Flash Image
• Select the magisk_patched.img file on your PC
• Wait for flash to complete

Reboot and verify root:

• Type: fastboot reboot
• After phone boots, open Magisk app
• Verify Magisk shows as installed (green checkmark)

This root is temporary. We will remove it at the end.

Step 6: The Permanent CPID Fix (Critical Step)

Open the CPID tool:

• In the toolkit main window, click on the Tensor CPID Tab
• Click Fix CPID button
• The toolkit will prepare your device and communicate with the modem

This step works identically on oriole (Pixel 6), bluejay (Pixel 6A), and raven (Pixel 6 Pro).

When the IMEI dialog box appears:

This is the most important decision in the entire process.

Option A (Recommended for all three models): Dial *#06# on your phone now. If your original IMEI is already visible (not zeros), click SKIP on the dialog box. The toolkit will lock that existing IMEI permanently to the NV data partition. Do not re-enter it manually.

Option B: If the IMEI is still showing 0 or null, type your original 15-digit IMEI number into the dialog box and click Apply. The toolkit will write it to the device and then lock it permanently.

How to find your original IMEI if you do not know it:

• Check the sticker on your phone’s original box (look for “IMEI 1” and “IMEI 2”)
• Look on the SIM card tray (some Pixel 6A bluejay models have it printed there)
• Check your Google account purchase history
• Contact your carrier for the original IMEI

Wait for success confirmation: The toolkit will show a green success message. Do not disconnect or reboot until you see this message.

Step 7: Reflash Stock Firmware (Remove Root)

After CPID fix is confirmed:

• Reboot phone to bootloader mode
• In the toolkit, go to Flash Tab again
• Flash the same stock firmware you used in Step 4 (must match your oriole/bluejay/raven)
• Wait for completion

This step completely removes Magisk root and restores the original boot image. Your IMEI fix remains untouched underneath. You now have a clean, secure, unrooted system with a permanently fixed IMEI.

Step 8: Relock the Bootloader

For full security and to pass SafetyNet checks:

Why relock the bootloader? Banking apps, Google Pay, WhatsApp, Netflix, and many other apps refuse to run on devices with unlocked bootloaders. Relocking restores full security. This applies to oriole, bluejay, and raven equally.

Lock the bootloader:

• Keep phone in bootloader mode
• In the toolkit, go to Repair Tab → Fastboot Functions
• Click Lock Bootloader
• Confirm the warning on your phone (use volume keys to select YES, power to confirm)

The phone will relock the bootloader and perform a factory reset. This is normal. All data will be wiped one final time.

Step 9: Verify the Fix Permanently

After the phone reboots:

• Complete the Android setup wizard
• Go to Settings → About Phone → IMEI
• Dial *#06# on the phone dialer

Your original IMEI should be visible.

Now for the ultimate test on your device:

• Go to Settings → System → System Update
• Download and install the latest OTA update available
• After the update completes, check IMEI again using *#06#

Your IMEI is still there. The fix worked permanently on your Pixel 6 (oriole), Pixel 6A (bluejay), or Pixel 6 Pro (raven).

7. Important Notes & Warnings

• ⛔ Do NOT enter a fake or incorrect IMEI. Only use your device’s original 15-digit IMEI. Entering a non-matching IMEI is illegal in many countries and will cause network registration failures. This applies to all three models.

• 🔑 The “Skip” button is not a bug. If your IMEI already shows correctly when the dialog appears, click Skip. Do not re-enter it. The toolkit has already restored it automatically. This works the same on oriole, bluejay, and raven.

• 📱 Root is temporary. We root only to apply the CPID fix. Step 7 (reflashing stock firmware) completely removes root. Your final system is 100% stock and unrooted.

• 🔒 Relocking bootloader is safe after this fix. Unlike temporary IMEI fixes that break when the bootloader is locked, this permanent fix survives relocking. You will have full SafetyNet pass on your oriole, bluejay, or raven.

• 💾 Back up before starting. Bootloader unlock wipes data. Step 1 (unlock) and Step 8 (relock) both wipe data. There is no way to avoid this. Back up everything.

• 📦 Use stable firmware only for your exact model. Beta firmware may have different partition layouts that break the CPID fix. Always use the latest stable build from Google’s official factory images page. Double-check you downloaded firmware for oriole (Pixel 6), bluejay (Pixel 6A), or raven (Pixel 6 Pro).

• 🌐 OTA updates are safe after this fix. Once the CPID is locked to NV data, future OTA updates cannot overwrite it. You can update normally without fear of losing IMEI again.

• ⚙️ Do not disconnect during CPID fix. The CPID repair process writes to critical NV partitions. Interrupting this process can hard-brick your phone regardless of model. Wait for the green success message.
