Mi A0101 Test Point New [portable] -

To find the test point for the Xiaomi Mi A0101 (commonly known as the

), you generally need to disassemble the device to access the motherboard. This process is typically used to force the device into EDL (Emergency Download) Mode for unbricking or flashing firmware. 🛠️ Hardware Test Point Guide Mi Pad 1 (A0101

), the test points are used to trigger the Nvidia Tegra bootloader mode (APX mode) or EDL equivalent.

Preparation: Power off the device and remove the back cover carefully. Disconnect Power

: It is critical to unplug the battery connector from the motherboard to prevent short circuits. Locate the Points: On the

motherboard, look for two small gold pads (often near the eMMC or CPU shielding).

Note: In some versions, you may need to short a specific pin to ground (the metal shielding) while connecting the USB cable.

Short the Points: Use metal tweezers to bridge the two points.

Connect to PC: While holding the short, plug the USB cable into your computer. mi a0101 test point new

Verify Connection: Open Device Manager on your PC. You should see a new entry under "Ports" or "Other Devices" (often appearing as NVIDIA USB Boot-recovery or similar for this specific model). 💻 Software Test & Diagnostic Codes

If your device is still functional and you are looking for Internal Hardware Tests (CIT Mode), use these dialer codes: Main Diagnostic Menu: *#*#64663#*#* or *#*#6484#*#*.

Phone Information: *#*#4636#*#* (Shows signal strength, battery info, and WiFi status). Battery/Charging Info: *#*#6485#*#*. ⚠️ Important Warnings

Risk: Opening your device and shorting pins carries a high risk of permanent hardware damage. Only attempt this if the device is "hard-bricked" and software methods fail.

Drivers: Ensure you have the Official Xiaomi Drivers or the Nvidia Tegra APX drivers installed so your PC recognizes the device once it's in test mode.

Software Alternative: Before disassembling, try entering Fastboot mode (Power + Volume Down) and use a tool like the Xiaomi ADB/Fastboot Tools to reboot into EDL via command. If you're having trouble, could you tell me:

Is your device completely dead (black screen) or stuck on a logo? Are you trying to unbrick it or remove a lock? Do you have the motherboard exposed yet?

Xiaomi Mi Pad (model A0101) is an older tablet (released in 2014) powered by the Nvidia Tegra K1 To find the test point for the Xiaomi

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.

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?

Since the Mi A1 is an older device (released in 2017), a "new" test point usually refers to a newly discovered location on the motherboard by repair communities, or a clarification for users having trouble finding it under the metal shield.

Here is a feature breakdown of the Mi A1 Test Point procedure.

6.2 Verifying Fastboot Detection

# Power off the phone, then hold Volume‑Down + Power to enter fastboot
fastboot devices
# Expected output:
# 1234567890ABCDEF    fastboot

If the phone does not show up, you’re either in the wrong mode (use the test‑point) or the drivers are missing.

4. Observations

Step-by-Step Disassembly:

  1. Power down the phone completely. If it is bricked, proceed anyway.
  2. Remove the SIM tray.
  3. Use a heat gun or hairdryer to heat the back cover edges (plastic back on Redmi A1). Pry it open gently starting from the charging port area.
  4. Unscrew all visible Phillips screws holding the plastic midframe.
  5. Carefully detach the plastic midframe using a pry tool, taking note of any flex cables (fingerprint, side buttons).

Once the motherboard is exposed, you are looking for two small, unmarked gold or copper pads. On the new revision of the mi a0101 motherboard (labeled P826 or E1248 near the SIM slot), the test points are located:

Crucial Visual Cue: Look for a tiny white triangle printed next to a copper pad. That is ground (GND). The other pad is the signal point. The new method uses these two specific pads—not the EMI shield or screw holes as some older guides suggest.

Troubleshooting Common "New" Errors

| Error Code | Meaning | Solution (new method) | | --- | --- | --- | | STATUS_BROM_CMD_SEND_DA_FAIL | Wrong DA file | Use the updated DA_SLA_New.bin. Do not use the default DA. | | S_BROM_DOWNLOAD_DA_FAIL (2004) | Driver signature error | Disable Windows driver signature enforcement. Reinstall MTK drivers in test mode. | | S_SECURITY_SECURE_USB_DL_IMAGE_SIGN_HEADER_NOT_FOUND | Authentication needed | The new test point method should bypass this. If not, you need an auth bypass tool (e.g., MCT or UnlockTool) alongside the short. | | ERROR : STATUS_DEVICE_CTRL_EXCEPTION (0xC0050005) | Shorting pad incorrect | You are likely using the old test point. Re-verify the new pads (near TP2230). | | Device disconnects after 2 seconds | Weak battery or bad short | Connect a charged battery. Do not rely on USB power alone. Ensure tweezers maintain constant pressure. |

7.2 Flashing a Stock Image (MiFlash)

# 1️⃣ Download the official fastboot flashable image package (e.g., from Xiaomi’s site)
# 2️⃣ Unzip to a folder: C:\MiFlash\A0101\
# 3️⃣ Open MiFlash (run as Administrator)
MiFlash.exe
# • Select the folder
# • Choose “Clean all” (erases userdata & cache)
# • Click “Refresh” – your device should be listed as “Qualcomm HS‑USB QDLoader 9008”
# 4️⃣ Click “Flash”. Wait ~5‑7 minutes.
