Download Realme P3x 5G RMX3944 Flash File Firmware:

I found several sources hosting the official Realme P3x 5G (RMX3944) stock firmware (flash file), including:

  • offering RMX3944export_11_15.0.0.504EX01_2025012213440000, along with OplusFlashTool and USB drivers
  • ROMexperts, with the same version of the flash package, firmware tools, and drivers
  • FirmwareBD and addROM, which also provide the stock ROM under the file name Realme_P3X_5G_RMX3944_MT6835_EX_11_15.0.0.504EX01_250122_MXML.zip (~7 GB)

🔧 What You’ll Need

  1. Stock firmware ZIP — e.g., RMX3944export_11_15.0.0.504EX01_…
  2. OplusFlashTool (sometimes labeled Realme Flash Tool or MSM Download Tool)
  3. MediaTek & Realme USB drivers for Windows
  4. A Windows PC, USB cable, and ~50% phone charge.

🚀 Flashing Instructions (Typical Workflow)

  1. Download and extract the firmware, flash tool, and drivers.
  2. Install MediaTek/Realme USB drivers on your PC.
  3. Launch the flash tool (e.g., OplusFlashTool_v5.6.44.0).
  4. Boot your phone into EDL mode: power off, then press and hold Volume Up + Volume Down, and connect via USB.
  5. The tool should detect “MediaTek port” in Device Manager — click Start All in the tool .
  6. Wait for the process to complete; your device should reboot with a fresh firmware install.
  7. After flashing, optionally perform a factory reset (via Settings → Additional Settings → Backup & Reset) to clear data.

⚠️ Key Precautions

  • Ensure the firmware exactly matches your model (RMX3944) and region. Using incorrect files may brick your device.
  • Backup all your data, as flashing erases user data and apps.
  • Use the latest flash tool and drivers for compatibility — older tools may fail or cause errors.
  • Flashing carries inherent risk — proceed carefully and at your own payment. If unsure, consider professional help.

📚 Additional Resources

  • Official Realme USB driver page for Windows
  • Flashing guides (e.g., using Oplus/MSM tools) available on forum posts — the procedure is similar across Realme MTK devices
