This is often caused by corrupted system files, failed updates, or software bugs within the operating system. When standard factory resets fail, the ultimate solution is to perform a clean install of the official Stock ROM (Firmware).
In this guide, we will provide a step-by-step tutorial on how to fix the auto-restart problem by flashing the latest firmware using Odin.
📥 Requirements Before You Start
To ensure a successful repair, prepare the following:
Official Firmware: Download the specific SM-J500FN firmware (ensure the PDA/CSC matches your region).
Samsung USB Drivers: Installed on your PC.
Odin Tool: Latest version of the Odin flashing tool.
Battery: At least 50% charge.
USB Cable: Use an original Samsung high-quality cable.
🔧 Step-by-Step Flashing Guide (The Fix)
Step 1: Enter Download Mode
Turn off your SM-J500FN. Press and hold the Volume Down + Home + Power buttons simultaneously. When the warning screen appears, press Volume Up to enter Download Mode.
Step 2: Prepare Odin on PC
Launch the Odin.exe file. Connect your phone to the PC via USB cable. You should see an "Added!!" message in the log box, indicating a successful connection.

Extract the downloaded firmware zip file. You will usually find 4 or 5 files starting with BL, AP, CP, and CSC. Click the corresponding buttons in Odin and select the files:
BL: Select the file starting with BL...
AP: Select the file starting with AP... (This is the largest file and may take a moment to load).
CP: Select the file starting with CP...
CSC: Select the file starting with CSC... (Use "HOME_CSC" to keep data, or "CSC" for a clean wipe—recommended for restart problems).
Step 4: Start the Flashing Process
Click the Start button. Wait for the process to complete. Once finished, Odin will display a green "PASS!" message, and your phone will reboot automatically.
