- Download and Extract Firmware Files
- Download the firmware package using one of the provided mirror links.
- Extract all the files to a folder on your computer. You should find the firmware files, USB drivers, the Infinix Flash Tool, and possibly a user manual.
- Install USB Drivers
- Navigate to the driver folder that you extracted from the firmware package.
- Run the driver installer and follow the on-screen prompts. This allows your computer to recognize your Infinix Note 50 Pro 4G X6855.
- After installation, it’s a good idea to restart your PC to make sure the drivers are loaded correctly.
- Launch Infinix Flash Tool
Open the folder containing the Infinix Flash Tool and run the application. It’s best to right-click and select “Run as administrator.”
In the tool, click on the “Brower” button (it might be labeled slightly differently). This button helps you load the scatter file, which tells the flash tool how to write the ROM to your device.
Now, navigate to the extracted firmware folder and select the scatter file (it usually ends with `.txt`).
- Start the Flashing Process
First, make sure your Infinix Note 50 Pro 4G X6855 is powered off. Have your USB cable ready to connect it to your computer.
Once the scatter file is loaded and your phone is ready, click the “Start” button in the Infinix Flash Tool. Then, connect your powered-off phone to the computer using the USB cable.
The flashing process will begin. This can take several minutes, so please be patient and do not disconnect the cable.
When the flashing is successfully completed, you will see a green checkmark appear on the screen.
- Reboot and Set Up
- After you see the green checkmark, disconnect your Infinix Note 50 Pro 4G X6855 from the computer and power it on. The first boot after flashing might take a bit longer than usual.
- Follow the on-screen setup wizard to configure your device as if it were new, since it has now been restored to factory settings.
Common Issues and Troubleshooting Tips
If you run into any problems while trying to flash your device, here are a few common issues and how to fix them:
- Device Not Recognized: Make sure the USB drivers are installed correctly. Sometimes, trying a different USB port or a different USB cable can solve this.
- Flashing Errors in Infinix Flash Tool: Double-check that you’ve loaded the correct scatter file and that your firmware download isn’t corrupted. Downloading the firmware again often fixes this.
- Boot Loop After Flashing: If your device gets stuck in a boot loop (keeps restarting), try performing a factory reset from the recovery mode. If that doesn’t work, you might need to reflash the firmware.
Missing IMEI or Corrupt Baseband?

- Install the Appropriate Driver: Make sure you have installed the MediaTek driver from the “Pre-Requirements” section above.
- Use a Write Tool: You’ll need a specialized tool like the SN Write Tool to restore your IMEI.
- Enter Your Original IMEI: Open the SN Write Tool, connect your device to the PC, and carefully enter your original IMEI numbers for both SIM slots.
- Begin the Write Process: Click the “Start” button in the tool and wait for it to finish restoring your IMEI.
- Restart and Verify: Once the tool confirms it’s done, restart your phone and check if the IMEI numbers are back by dialing *#06#.
