N950F U13 Repair IMEI Solution | Tested Samsung Fix

If your Samsung Galaxy Note 8 (N950F) is stuck with a damaged or invalid IMEI after update to U13 firmware, this guide will help you fix it step-by-step. Many users face IMEI null, no baseband, or network not registered issues after flashing the latest firmware. Don’t worry — this tested N950F U13 Repair IMEI Solution works safely without tripping Knox or damaging your EFS.

When you flash or upgrade to U13 (Android 9 or 10) firmware, the EFS or modem partitions can get corrupted, leading to an invalid or missing IMEI. In most cases, the baseband shows as “Unknown” or “No Service.”

This typically happens due to:

Flashing an incompatible modem or CSC file
Corrupted EFS partition
IMEI overwritten during full firmware flash
Downgrade attempt from higher U firmware
