Xiaomi frequently revises motherboards. An older guide might show a test point near the CPU or under a specific EMI shield. The "new" MI A0101 layout (found on units manufactured after mid-2022) has shifted the primary test point location to improve water resistance or reduce accidental shorts during assembly.
| Parameter | Expected | Measured | Result | |-----------|----------|----------|--------| | DC voltage (TP to GND) | [] V | [] V | PASS/FAIL | | Resistance to GND | [] Ω | [] Ω | PASS/FAIL | | Signal integrity | [spec] | [actual] | PASS/FAIL | | Continuity to target node | YES | YES/NO | PASS/FAIL |
Crucial Warning: Do not follow this guide if you do not have an A0101 board. Verify your device: mi a0101 test point new
Check your phone’s "About Phone" menu. If the codename is "lime" , you have the A0101.

(Visual description for text-only environments: Imagine the CPU shield is a square in the center. Move left 10mm. There is a blank space with two small black components. Between those components is a single, lonely copper circle – that is TP106, the new test point).
If you cannot find the golden pad, look for a via (a small hole) labeled "TP106" or "EDL" in silver text too small to read without a magnifying glass. The "new" revision removed the text to deter unauthorized flashing. | Parameter | Expected | Measured | Result

TL;DR:
The Redmi 4A (model A0101) now has a newly‑discovered test‑point that lets you bypass the traditional fastboot/bootloader unlock method. This post walks you through the hardware location, the wiring, the required software, and a step‑by‑step flashing workflow.
# 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.
