Understanding the Redmi 5A Test Point
A test point is a small spot on your phone’s circuit board. It lets you directly access the phone’s system. It’s like a secret door to fix software problems.
What is a Test Point?
Test points let you put your phone into EDL mode. This is also called Emergency Download mode. It helps bypass the usual boot process. You might wonder if you could just use ADB or fastboot, but these needs the phone to be partly working. A test point works even when your phone is totally bricked!
Why Use a Test Point on the Redmi 5A?
You might need a test point when your Redmi 5A is bricked, has failed updates, or is locked with FRP. Test points can bypass the lock. They let you flash new software. Think of it as a bypass to fix severe software issues.

- Remove the SIM card tray.
- Carefully open the phone using plastic opening tools. Start from the back cover.
- Unscrew the screws covering the motherboard.
- Locate the test point near the processor. It’s a small, exposed metal pad. The image below shows the location.
- Use tweezers to short this test point to ground. (The metal shield counts as ground.)
Performing the Flash: A Practical Guide
Flashing is like reinstalling the operating system. It fixes software problems. You’ll need specific software and drivers.
Software and Driver Requirements
You’ll need the MiFlash Tool. Also, grab the Qualcomm drivers. Use reliable sources for downloads. These will interface between your PC and the Redmi 5A’s chipset.
Connecting the Test Point and Flashing the Firmware

- Browse and select the firmware file.
- Short the test point to ground with tweezers.
- Connect your phone to the computer via USB.
- Click “Refresh” in MiFlash Tool. Your phone should show up as a COM port.
- Click “Flash” to start the flashing process.
- Wait until the process finishes. Don’t disconnect during flashing!
Troubleshooting Common Issues
Sometimes things go wrong. Here are some fixes.
Device Not Detected
- Check your drivers. Reinstall them if needed.
- Try a different USB cable. Some cables don’t carry data well.
- Make sure you’re shorting the correct test point.
- Restart your computer.
Flashing Errors
- Check your firmware version. Is it right for your phone model?
- Make sure the firmware file isn’t corrupted. Redownload it if needed.
- Try flashing in “Download” mode instead of “Clean all” mode.

- If all else fails, seek professional help.
Advanced Techniques: Jumper Ways
Jumper ways are like detours for broken circuits. You’ll need soldering skills. Consider calling an expert.
Understanding Jumper Ways
A jumper way is a wire connecting two points on a circuit board. This is how you bypass broken or damaged traces. Only use this if a trace is damaged.
Redmi 5A Jumper Way Solutions
Here are some common jumper way diagrams. Be very careful!
- Power Button: If the power button isn’t working, connect a wire from the button’s contact to the motherboard’s power line.
- Charging Port: If your phone isn’t charging, connect a wire from the charging port’s VCC pin to the battery’s positive terminal.
Disclaimer: These solutions are advanced. Wrong jumper connections can damage your phone. If you don’t know what you’re doing, seek professional help!
