If your Samsung J2 is stuck in a boot loop (it turns on but never loads the home screen), the only way to fix it is often by flashing the stock firmware using the Odin tool. Odin cannot "see" your phone without the specific Samsung drivers installed. This usually involves the device being in "Download Mode."

For developers or advanced users who want to use the Android Debug Bridge (ADB) to sideload apps, take logs, or modify the system, the ADB interface driver is required. The official Samsung driver package includes the necessary components to make adb devices recognize your J2.

Restart your PC. Hold while clicking Restart. Go to Troubleshoot > Advanced Options > Startup Settings > Restart > Press 7 (Disable driver signature enforcement). This prevents Windows from blocking the legacy J2 driver.

Once you have downloaded the driver file (usually named something like SAMSUNG_USB_Driver_for_Mobile_Phones.exe ), follow these steps to install it on your Windows computer.
