Realme 3 Pro (RMX1851) won't boot past the logo, is locked out with a forgotten FRP account, or needs a clean firmware reflash, this is the guide to bookmark. Since this hardware method comes before more invasive options like ISP programming. This guide covers the exact test point location for the RMX1851 — Realme 3 Pro (RMX1851) Test Point — and walks through the full process step by step.

With a Qualcomm SDM710 Snapdragon 710 under the hood, the RMX1851 communicates through Qualcomm EDL 9008 (HS-USB QDLoader) once it's in this state. From there, AMT Tool, Unlock Tool, UMT QcFire Tool, etc should pick up the device, giving you access to FRP reset, flashing, and IMEI fixes.

Before you start: Make sure Qualcomm USB Driver is already on your system before you start — it's the most common reason a correct test point still doesn't register.

RMX1851 Test Point / EDL Point Location

Find the two gold pads on the RMX1851 motherboard — shorting them as you plug in USB is what forces Qualcomm EDL 9008 (HS-USB QDLoader).

Important: Short only the correct pads shown above. Wrong contact can permanently damage the device.

How to Enter RMX1851 Test Point Mode (Step-by-Step)

Note: This involves opening the device physically. Hardware damage is not reversible.

1Power off the device. Get the phone into a full power-off state first. A simple restart skips this and isn't the same thing.
2Remove the back cover. Pop off the back cover using a plastic pry tool, working around the edges. If glued, a bit of heat (hair dryer or heat gun, 20-30 seconds around the rim) softens the adhesive.
3Disconnect the battery. Disconnect the battery before touching anything else on the board — a plastic pry tool makes this quick and safe.
4Locate the test point pads. Compare the board in front of you with the pinout image above to find the two gold contact points.
5Short the test points. Hold the tweezers across both points together, applying consistent pressure so the contact doesn't break.
6Connect USB cable to PC. Keep the short in place and connect the USB cable to your computer — the phone switches into Qualcomm EDL 9008 automatically.
7Verify in Device Manager. Look for "Qualcomm EDL 9008" in Device Manager under Ports — that's your confirmation it worked.
8Release the tweezers once confirmed. Device stays in EDL mode while USB is connected.
9Open your flash tool and proceed. AMT Tool, Unlock Tool, UMT QcFire Tool, etc should detect it automatically.

💡 Tip: If Device Manager shows "Unknown Device", reinstall Qualcomm USB Driver and repeat. Use a rear USB port, not a hub.

Frequently Asked Questions

Usually one of three culprits: a driver issue with Qualcomm USB Driver (fresh reinstall as Administrator fixes most cases), dirty test point pads, or a USB cable/hub that isn't passing data properly.

Yes, if you disconnect the battery first and short only the correct pads in the pinout image. Risk comes from touching wrong components or using excessive force near SMD parts.

Entering this mode alone does not erase data. Any FRP reset or flash performed in EDL mode will erase data. Always inform the customer first.

Disconnect USB and reconnect the battery. If it still won't boot, flash the stock ROM in EDL mode to restore firmware.
