In the world of smartphone repair and modification, few things are as simultaneously feared and revered as the Test Point. For Xiaomi and Redmi device owners, particularly those dealing with the motherboard codenamed "A0101" (commonly known as the Redmi 9T, Redmi 9 Power, or Redmi Note 9 4G), the test point is the last line of defense against a hard brick.
If you have arrived here searching for the "mi a0101 test point new" , you are likely staring at a dead screen, a device stuck in an endless boot loop, or a Qualcomm HS-USB QDLoader 9008 error that refuses to go away. This guide provides the latest, most accurate information on the new test point locations, procedures, and safety tips for 2025.
For the average user, the mi a0101 test point new method is an advanced, high-risk procedure. However, for technicians, tinkerers, or users facing a confirmed hard brick with no other options, it is the only lifeline.
The keyword "new" is critical because old tutorials will lead you to the wrong physical location or outdated software, resulting in endless errors. By following this guide’s updated pad positions (near TP2230/TP2231 on the bottom-left of the board) and using SP Flash Tool v6 with a modern DA file, you can successfully resuscitate a dead Redmi A1.
Final Checklist Before Starting:
If you succeed, your once-bricked mi a0101 will boot into a fresh stock ROM, as clean as the day it left the factory. If you fail, repeat the process carefully—many first-time attempts fail due to loose shorts or the wrong driver version.

The Xiaomi Mi Pad (A0101) test points are critical for forcing the device into Emergency Download Mode (EDL). This hardware-level bypass allows you to flash official firmware when the device is "bricked" (stuck in a boot loop) or when the bootloader is locked. Mi Pad (A0101) Test Point Guide Preparation
Tools: You will need a thin metal tweezer and a high-quality USB cable.
Disassembly: Carefully remove the back cover of the Mi Pad. Use a plastic pry tool to avoid damaging the internal components.
Safety: Disconnect the battery flex cable before proceeding to prevent short-circuiting other components. Locating the Test Points
The test points are two small gold-colored pads located on the motherboard, typically near the battery connector or the camera module.
Visual Reference: Look for two distinct circular pads marked specifically for factory diagnostics.
Identifying the Points: On the Mi Pad A0101, these are often found after removing the protective metal shield from the CPU/EMMC area. How to Enter EDL Mode
Launch Tool: Open your flashing software (like Xiaomi Flash Tool or SP Flash Tool) on your PC.
Short the Points: Use the tweezers to bridge (connect) the two test points together.
Connect USB: While holding the points together, plug the USB cable into your computer.
Verification: Check Device Manager on your PC. It should appear under "Ports (COM & LPT)" as Qualcomm HS-USB QDLoader 9008. Common Troubleshooting
Not Recognized: If the device appears as "QUSB_BULK," you must manually install the Qualcomm USB Drivers.
Bootloader Unlock: Entering EDL via test points is often the only way to bypass a locked bootloader if standard Fastboot methods fail.
Software Diagnostics: If your screen is flickering but the device is on, you can try entering CIT Mode by dialing *#*#6484#*#* to test hardware components.
💡 Key Takeaway: The test point method is a "last resort" for deep system recovery and should be handled with precision. I can provide more specific details if you need: The exact software version you are trying to flash. Specific error codes you see in the Mi Flash Tool.

Как перепрошить Xiaomi через Test Point - XIACOM mi a0101 test point new
Codename: Lazarus Point
The schematic was four generations old, printed on heat-faded paper that smelled of ozone and secrecy. In the center of the diagram, circled in red ink that had since turned brown, was a single node: MI-A0101.
“That,” whispered Kael, sliding the print across the concrete floor, “is the ghost in the machine.”
Leena picked it up. She’d been a hardware reverse-engineer for twelve years—had cracked bootloaders on three continents—but she’d never seen a test point with a prefix like MI. Military-Industrial, maybe. Or Mortality Index.
“What board?” she asked.
“Doesn’t exist,” Kael said. “Officially. It’s a controller core for a phased-array LIDAR system. Black project. Code name ‘Nyx.’ Three years ago, the whole team vanished. No bodies. No repos. Just… silence.”
Leena looked at the test point again. In normal engineering, a test point (TP) is just a bare copper pad or via—a place to clip a probe, measure voltage, or flash firmware during manufacturing. But MI-A0101 had a notation she’d never seen:
ACTIVE LOW. PULSE >50ms → CORE RESET. PULSE >2s → DEBUG UNLOCK. PULSE >5s → ???
“Question marks,” she said. “That’s not engineering. That’s poetry.”
“Or a warning,” Kael replied.
They were in a sub-subbasement of an abandoned R&D lab in the Zone Rouge—a place where even GPS refused to lock. The target board lay on an ESD mat: a matte-black PCB with no silkscreen, no labels, and no manufacturer logo. Just dense, laser-drilled vias and one exposed gold-plated pad labeled MI-A0101.
Leena connected her oscilloscope probe, a logic analyzer, and a precision pulse generator. Her hands were steady. Her heart was not.
“Standard reset first,” she said. “50 ms pulse.”
Kael nodded, recording everything on a disconnected tablet.
She touched the probe tip to the gold pad. Sent the pulse.
The board’s LED—the only component that ever showed life—blinked once. Then twice. Then went dark.
“Nothing,” Kael said. “No reset. No handshake.”
Leena frowned. That was wrong. A test point that didn’t respond to spec was either dead or lying.
“Step two,” she breathed. “Two seconds.”
She set the pulse width to 2.1 seconds. Contact.
For a moment, nothing. Then the board’s main processor—a ceramic package with its markings laser-etched off—began to warm up. Not hot. Warm. Like something waking from hibernation.
The debug port spat out a single line of hex:
A0101: SYSTEM_MODE_DEBUG. VOICE CONTROL ENABLED.
Leena and Kael exchanged a look. Voice control? On a LIDAR controller?
“Hello?” Leena said aloud, her voice flat.
The board’s tiny speaker—so small they’d mistaken it for a capacitor—crackled.
“Operator not recognized. Please recite authentication sonnet.”
Kael’s face went pale. “Sonnet? Who puts poetry in firmware?” Tip: Some users need to press Volume‑Up together
Leena ignored him. She’d seen weirder—air-gapped systems that required a specific jazz riff, radiation-hardened chips that answered only to haiku. But a sonnet?
“No,” she said slowly. “It’s not a test point. It’s a dead man’s switch.”
She looked at the schematic again. MI-A0101. The “MI” wasn’t Military-Industrial.
It was Mortality Index.
“The team that vanished,” Leena said. “They didn’t disappear. They locked themselves in. This board is the key to something—a weapon, a cache, a truth—and MI-A0101 is the only way in. Two seconds unlocks debug. Five seconds…”
She didn’t finish.
Kael grabbed her wrist. “Don’t.”
But Leena was already setting the pulse generator to 5.0 seconds.
“If I don’t,” she said, “someone else will. And they won’t ask questions. They’ll just hold it for six seconds, or ten, or until the board screams.”
She touched the probe to the gold pad for the third time.
The five-second pulse began.
At 3 seconds, the board’s LED turned red.
At 4 seconds, the speaker emitted a low, continuous tone—like a flatline slowed down a hundred times.
At 5 seconds exactly, the tone stopped.
The oscilloscope showed a single spike. Then the board went cold. Dead. No debug output. No LED. Nothing.
“You killed it,” Kael whispered.
Leena sat back, heart pounding. “No. I listened.”
She unclipped her probe and held the board up to the dim light. Under the gold plating of MI-A0101, something was etched into the copper layer below—visible only at an angle.
It read: LAZARUS PROTOCOL ACTIVE. WAKE WORD: ‘I REMEMBER EVERYTHING.’
Leena set the board down carefully, as if it were a sleeping animal.
“It’s not dead,” she said. “It’s waiting. And the test point wasn’t a switch. It was a signature. A promise. The moment someone holds that pulse for five seconds, the board knows—someone really wanted to know the truth.”
She looked at Kael.
“Now we just have to say the wake word. Out loud. Together.”
Kael swallowed. “What happens after?”
Leena didn’t answer. She just stared at the gold pad—MI-A0101—and the ghost of the team who had etched their final message into the copper before disappearing.
Outside, in the Zone Rouge, the wind picked up. And the board waited.
End of Part One.
Xiaomi Mi Pad (model A0101) is an older tablet (released in 2014) powered by the Nvidia Tegra K1 Modern users search for the "mi a0101 test
chipset. Because it uses an Nvidia processor rather than the more common Qualcomm Snapdragon found in most Xiaomi devices, the "test point" procedure for unbricking or flashing is different from the typical Qualcomm EDL (Emergency Download) mode. Understanding the "Test Point" for Mi Pad 1 (A0101)
For the Mi A0101, "test points" are typically used to force the device into a state where the computer can recognize the Nvidia Tegra hardware for low-level flashing (often referred to as or similar for Nvidia chips). Disassembly Required
: To access the internal test points, you must remove the back cover of the tablet.
: While specific "new" test point diagrams for the 2026 era are rare because the device is legacy, the standard test points are located on the mainboard, often near the LCD connector
. You are looking for two small gold contacts that must be shorted (connected) with metal tweezers. Power off the tablet and disconnect the battery. Short the two test points using tweezers.
While holding the short, connect the tablet to your PC via a USB cable.
If successful, your PC should recognize a new device (e.g., "NVIDIA USB Boot-recovery driver") instead of the standard "Mi Pad." Alternatives to Hardware Test Points
If you are trying to unbrick the device or remove a lock, hardware test points are a last resort. You can often use these software methods first: Fastboot Mode : Press and hold Power + Volume Down until the Mi Bunny appears. Recovery Mode : Press and hold Power + Volume Up Software Diagnostics : If the tablet still boots, enter *#*#6484#*#* in the dialer (or a diagnostic app) to run hardware tests. Service & Tools Flashing Tools Official Mi Flash Tool or specialized Nvidia Tegra flashing utilities. Disassembly Guide
: You can find step-by-step visuals for opening the device on YouTube tutorials
Are you attempting to fix a specific issue like a boot loop, a forgotten Mi Account lock, or a "hard bricked" device that won't turn on at all?
In older methods, you shorted the test point to a metal shield. In the new A0101 revision, the nearby shielding is coated with non-conductive paint.
If successful, your screen remains black, but your computer recognizes the device. This is EDL mode.
If you want, I can provide a step-by-step procedure tailored to a specific Xiaomi device model or point you to teardown resources — tell me the exact model and whether you need EDL or fastboot instructions.

Understanding the Mi A0101 Test Point for Hardware Repairs The Xiaomi Mi Pad (A0101), also known as the original 7.9-inch Mi Pad released in 2014, remains a popular legacy device for enthusiasts. However, like many older Android tablets, it can suffer from "hard bricks," where the software is so corrupted that it no longer responds to standard Fastboot or Recovery commands.
In these critical scenarios, technicians use the test point method to bypass the normal boot process and force the device into Emergency Download (EDL) Mode. What is the Mi A0101 Test Point?
Test points are physical contact pads located on the motherboard of a device. By "shorting" these pads (connecting them with a conductive tool like tweezers), you signal the processor—the Nvidia Tegra K1 in the case of the A0101—to enter a low-level maintenance state. Common reasons to use the A0101 test point:
Unbricking: Recovering a device that won't turn on or is stuck in a boot loop. FRP Removal: Bypassing Google Factory Reset Protection.
Firmware Flashing: Installing stock ROMs when the bootloader is locked.
MI Account Reset: Resolving account lock issues directly via hardware. Step-by-Step Guide to Accessing the Test Point
Warning: This process requires disassembling your tablet, which will void any remaining warranty and risks hardware damage. 1. Disassemble the Tablet Xiaomi MiPad 7.9 WiFi A0101 16GB (Xiaomi Mocha) - PhoneDB
The Xiaomi Mi Pad A0101 (also known as the Mi Pad 1) uses a NVIDIA Tegra K1 chipset, which does not utilize the standard Qualcomm EDL (Emergency Download) mode or its associated "two-dot" test points typically found on newer Xiaomi phones. Hardware Test and Flashing Methods
For the A0101 model, standard hardware interaction and recovery are typically handled through the following modes rather than physical motherboard test points:
Fastboot Mode: Turn off the device, then press and hold Volume Down + Power until the Mi Bunny logo appears. This is used for flashing official ROMs via the Xiaomi Flash Tool.
Recovery Mode: Press and hold Volume Up + Power to enter the stock recovery menu.
Hardware Diagnostic (CIT) Menu: To test internal components (screen, speakers, sensors) without opening the device, enter the following code into the dialer or through settings: Code: *#*#6484#*#* or *#*#64663#*#*.
Settings Path: Go to Settings > About Phone > Detailed info and specs and tap Kernel Version repeatedly until the test menu opens. Clarification on Similar Models
