Samsung Galaxy M12: How to Find and Use the Test Point for EDL Mode

Understanding the Test Point

• 💡 The test point on a Samsung Galaxy M12 is a service point used for direct communication between a computer and the phone's CPU, bypassing the operating system.
• 🎯 This direct CPU communication is essential for various service functions, including FRP bypass.

Tools and Preparation

• 🛠️ To access the test point, you will need to disassemble the phone. Required tools include a Phillips #00 screwdriver, plastic prying tools (thin and thick), and potentially pliers.
• ⚠️ It is crucial to power off the phone before starting any disassembly.

Disassembling the Samsung Galaxy M12

• 🔓 The process begins with removing the SIM card tray.
• 📱 Next, carefully pry off the back cover using thin plastic tools, starting near the SIM card slot. No heat is required as there is no glue.
• ⚠️ Be cautious around the side buttons, as there is a tape connecting them to the phone; remove this tape carefully.
• 🔩 Unscrew the top plastic shield using a Phillips #00 screwdriver, keeping the screws organized.
• 🔋 Disconnect the battery before proceeding to locate the test point.

Locating and Using the Test Point

• 📍 The test point consists of two small pads located on the motherboard.
• 🔌 To enter EDL (EUB/EUM) mode, disconnect the battery, wait 5 seconds, reconnect it, then short the two test point pads together while simultaneously plugging in the USB cable connected to your computer.
• 🚀 This action establishes direct CPU communication, enabling advanced service operations like FRP bypass.
