This is the most important update for all users of Global Unlocker Pro.

🌍 Carrier ReLock (2026) – NOT SUPPORTED

Devices that are updated to 2026 firmware are NOT supported for Carrier ReLock.


🔷 Important Instructions

  • Devices that have been Carrier Relocked must stay on 2025 firmware
After completing the ReLock process, the tool will:
  • Automatically disable system updates
  • Prevent upgrading to 2026 firmware

This is done to protect the device from losing network access.


🔧 What Happens if Device Updates to 2026 Firmware?

If your device is updated accidentally, follow these steps:

✅ Downgrade the device back to 2025 firmware
✅ Flash the firmware properly
✅ Network service will start working again

⚠️ Very Important:
After flashing, always disable system updates again.


⚠️ Important Note

🚫 Carrier ReLock does NOT work on 2026 firmware
📌 This is a firmware limitation, not a problem with the tool


Why This Notice is Important
