Owners of Xiaomi Mi Play smartphones often face situations where the software stops responding, the device gets into an endless reboot or completely refuses to turn on. In such cases, standard recovery methods, such as resetting buttons or connecting to the Mi Flash Tool in normal mode, are powerless. The only right solution is to force the device to Emergency Download (EDL) mode, which allows you to perform low-level flashing.
To enter this diagnostic mode on devices with closed loader or blocked access to ADB requires the physical closure of special contacts on the motherboard, known as Test Point. Understanding their location and the correct technique of working with them are critical skills for successful recovery of Mi Play (daisy) without going to the service center.
In this article, we will discuss in detail where exactly the necessary contacts are on the board of your smartphone, what tools will be needed to safely conduct the procedure and how to avoid common errors. Close Test Point on a phone turned on can lead to short circuit and failure of the power controller, so strictly follow the instructions for de-energizing the device. We will look at the nuances of disassembling the case and the algorithm of actions that will ensure the maximum probability of successful entry into the 9008 mode.
What is Test Point and Why You Need It on Xiaomi Mi Play
Qualcomm’s technology, which underpins the Snapdragon 625 processor installed in Xiaomi Mi Play, provides a special boot protocol. Unlike the standard Fastboot mode, which is used for regular updates, the EDL mode (Qualcomm HS-USB QDLoader 9008) is the highest priority. It allows you to write data directly into memory, bypassing the bootloader and operating system. This is the only way to revive the phone if the bootloader or relays are damaged.
Many modern Xiaomi smartphones have a software-enabled entry that requires an authorized Mi Account with employee rights. However, physical closure of Test Point allows you to bypass these restrictions. When certain contacts are closed on the motherboard at the time of power supply, the processor receives a signal to ignore the standard boot sequence and go straight to firmware standby, which makes it possible to restore even the "bricks" that do not respond to the volume buttons.
This method requires caution and precision. Incorrectly closing adjacent elements can lead to irreversible consequences. It is important to understand that you are interfering with the hardware of the device. Before starting any manipulation, you need to make sure that the battery has at least a minimum charge, although in case of complete failure of the phone, power will still have to be supplied via USB after the circuit.

Tools and workplace preparation required
Before starting dismantling Xiaomi Mi Play, you need to prepare the workplace and tools. The process requires care, as the body of the smartphone is tightly assembled, and the internal components are compact.The lack of suitable tools can damage the plumes or chipped body, which will complicate further repairs.
- 🔧 Sets of screwdrivers: you will need a cross sized screwdriver PH000 or PH00 for twisting the screws of the motherboard and modules.
- 🎹 Plastic mediators: Use them to open the case and turn off the plumes so as not to damage the plastic and create static electricity.
- 🔌 Tweezers: necessary for accurate closure of contacts, it is better to use the antistatic version with thin legs.
- 💡 Light source: A good lamp or magnifier will help you clearly see the fine contacts on the board, as they can be hidden under a layer of dust or factory protection.
It is also crucial to ensure that there is no static electricity in the workplace, such as using an antistatic mat or at least touching a grounded metal object regularly before touching the insides of a smartphone, and a static discharge can instantly disable the sensitive electronics of the motherboard, turning a software problem into a hardware problem.
☑️ Preparation for the procedure
Use high-quality computer connection USB-cable, preferably original or certified, and port USB 2.0, as they are often more stable with firmware mode.Install the required Qualcomm drivers in advance HS-USB QDLoader and Mi Flash Tool to check device definition in Task Manager immediately after connection.
Xiaomi Mi Play Disassembly Process for Accessing the Board
Access to the Xiaomi Mi Play motherboard starts with the rear cover being removed. Unlike many modern models, the lid is removable, but requires careful handling. SIM-So you can use a thin plastic mediator or suction cup to gently flick the locks around the perimeter of the body.
Removing the back cover will open up the battery and a protective plastic lining covering the main plumes. On the Xiaomi Mi Play, the battery is not glued to the dead but can be fixed to double-sided tape. The first thing you need to do is to disconnect the battery plume from the motherboard. This is a critical step to prevent short circuits during further disassembly.
Next, unscrew the screws that hold the middle plastic frame or motherboard protection. The number of screws can vary, so carefully inspect the perimeter of the board. Some screws can be hidden under stickers or rubber plugs. After unscrewing all the fasteners, carefully remove the protective plate, freeing access to the main board and connectors.
💡
When you unscrew the screws, spread them out in order of removal or use a magnetic mat with markings. Rotors of different lengths can stand in different places, and if you confuse them, you can damage the thread or break the board with a long screw.
Now the Xiaomi Mi Play motherboard is available for visual inspection. Take your time to look for the points of closure. Carefully inspect the board for a factory moisture film or varnish. Sometimes Test Point contacts can be closed with a thin layer of insulation that you will have to carefully remove with a scalpel if the circuit fails.
Where is Test Point on Xiaomi Mi Play: Scheme and Location
On the Xiaomi Mi Play (codenamed daisy), the EDL entry contacts are located on the front of the motherboard. Unlike some other models where the dots can be scattered, they are in close proximity to the processor or the main plume connectors, most often a pair of contacts that need to be closed between themselves or by a mass.
The specific location of Test Point on the Xiaomi Mi Play board is usually at the top of the board, near the main plume connector or near the camera module. The dots can look like small golden circles or rectangular areas without insulation. In some board revisions, they can be signed in fine print as "TP" or "EDL", but most often they are just two contacts located next to each other.
To successfully enter the 9008 mode, you must close these two contacts with a metal object (pincet, needle) and, holding the circuit, connect. USB-In some variations of the circuit, one particular contact is required to be closed on the metal screen of the module (mass). The exact configuration depends on the board revision, so if the two points are not closed, try to close one of them on the nearest metal element of the case or screen.
| Element | Location. | Action. | The result |
|---|---|---|---|
| Test Point 1 | Top of the board, by the plume. | Close with TP 2 | Entrance to EDL (9008) |
| Test Point 2 | Next to TP 1 | Close with TP 1 | Entrance to EDL (9008) |
| Massa (Ground) | Metal screen | Close with TP | Alternative entrance |
| Battery connector | The bottom of the fee | Turn off before work | Security |
Visually, the dots can be barely visible. Use a magnifier or a macro shot on a zoom phone to consider the marking. If you're not sure which contacts are the target, look for high-resolution photos of Xiaomi Mi Play parsing where the arrows indicate the right places. A mistake in choosing contacts usually just doesn't work, but there is always a risk of hitting adjacent chains.
Algorithm of entering mode 9008 through closure
Once you've reached the board and you've identified the contacts, you can start the procedure. First, make sure the battery plume is off. That's a requirement. Then take tweezers or thin wire and attach it to the points you find at Test Point. Without removing the tool, press and hold the contacts.
Holding the circuit, connect. USB-And the other end of the cable is already connected to the computer, and at that point, the phone has to vibrate or make a sound of the device's connection. EDL It often works without displaying an image. Look at Windows Device Manager: Ports (COM and LPT)" Qualcomm should appear. HS-USB QDLoader 9008.
If the device is identified, you can release the contacts and turn off the cable. If the computer is not responding, try changing the device. USB-Port, cable, or slightly change the position of tweezers on the contacts. Sometimes it takes several attempts to catch the right moment of closure. Also make sure that Qualcomm drivers are installed correctly and do not conflict with other devices.
⚠️ Note: Do not keep your contacts closed for longer 5-10 If you don't get the power right the first time, you can overheat the power circuits of the processor, and if you don't get the first time, you can turn off the cable, release the contacts, wait a few seconds, and try again.
Once the COM port is successfully identified, you can run a firmware program. In the Mi Flash Tool, select Clear All or Clear All and Lock mode if you want to clear the data completely and return the factory lock. The firmware process takes a few minutes. Do not interrupt it or turn off the phone until the success message appears.
Common mistakes and problems with Test Point
One of the most common problems is the lack of response of the computer. USB-You can use a cable that only transmits charge, not data. Always check the cable on other devices. Also, the problem may be in missing or incorrect Qualcomm drivers. Try installing them manually through the Device Manager, indicating the path to the driver folder.
Another common mistake is choosing the wrong contacts, and there are many similar points on the board, and closing the wrong ones may not have any effect. COM-The port doesn't appear, double-check the circuitry for your specific board revision.Occasionally, manufacturers make changes to the layout of items in different batches of Xiaomi Mi Play.
Also, users often forget to turn off the battery before they turn off.This is a gross error that can short-circuit and cause the power controller to fail.Always work with the power outage, connecting power only when the USB is closed.If the phone has been severely drained, leave it on charge (via Test Point or the usual way, if possible) for 15-20 minutes before trying to run the firmware.
💡
The success of the operation depends on three factors: the correct contacts Test Point, the correct contact. USB-Data cable and installed Qualcomm drivers.
