Huawei Honor 90 Lite (CRT-NX1) Test Point

The Huawei Honor 90 Lite (model CRT-NX1) test point refers to specific hardware contact points on the phone’s motherboard that can be used to force the device into Emergency Download Mode (EDL / download mode) or to trigger a factory test interface. This method is used by technicians when the device cannot enter recovery, fastboot, or standard service modes.


📍 What Is a Test Point?

A test point on a smartphone motherboard is a tiny metal pad or pair of pads that can be shorted or probed to make the device enter a special service mode. On many devices like the Honor 90 Lite, this can bring the phone into EDL/Download Mode, allowing the device to be detected by software tools even when it refuses to boot normally. 

In EDL mode, the phone communicates with the computer using a special low-level interface. Once detected, tools such as SP Flash Tool or other Qualcomm/MediaTek flashing tools can be used to flash firmware, repair partitions, or reset FRP locks.

📍 Honor 90 Lite Test Point – Basic Method

General Steps to Use the Test Point

  1. Turn OFF the phone completely (no battery or power).

  2. Open the back cover and remove shielding to expose the motherboard.

  3. Locate the test point — typically a small pair or group of metallic contacts near the SoC or main IC area.

  4. Short the test point carefully using a fine wire, tweezer, or conductive probe.

  5. While the test point is shorted, plug the USB cable into the phone and into your computer.

  6. Check your PC’s Device Manager — you should see a COM/EDL device appear (e.g., Qualcomm HS-USB QDLoader 9008 or a similar Qualcomm/MediaTek interface if supported).

  7. Once detected, you can use a compatible flashing or service tool for repair or FRP bypass.

⚠️ Important: Always power OFF the phone before shorting test points, and avoid prolonged shorts that could damage components. Use a fine conductive tool and proceed gently.


🔍 Notes on Honor 90 Lite CRT-NX1 Test Point

  • Honor 90 Lite uses a Qualcomm/MediaTek-style chipset path for EDL mode — test point can help force the device into service mode when normal methods like adb, fastboot, or recovery don’t work.

  • Many service tools and boxes support resetting FRP or unbricking Honor models via EDL once the test point is used.

  • Some updates to service tools now include preloader support without needing to use test points for Honor 90 Lite, meaning the phone may be detected automatically in some cases, but the test point remains important when automatic detection fails.



📌 EDL Mode and Tools

Once the test point successfully triggers EDL mode, you can connect the phone to the PC and use tools like:

SP Flash Tool (with test point + EDL) — for flashing firmware via scatter files if supported.
Qualcomm/MTK flashing tools — depending on chipset specifics.
FRP bypass tools — that can operate once the phone is in a low-level service mode.


⚠ Safety and Precautions

❗ Before working with test points, disconnect battery power and take ESD precautions.
❗ Test point contacts are extremely small — only use fine probes or wires.
❗ Do not short unrelated pads, as this risks permanent hardware damage.

📌 Final Tips

✅ If your phone doesn’t enter normal service modes, the test point method often triggers EDL/Download Mode for detection.
✅ In some cases, new service box updates support automatic detection without physically shorting — but test points are a reliable fallback.
✅ Test points vary by board revision — always visually confirm exact pad pattern before touching.
✅ Use magnification and a steady hand to avoid mistakes on tiny motherboard pads.
