Has your MediaTek Android phone got stuck in a bootloop, or are you trying to restore it after a failed update? SP Flash Tool is the most trusted software used by millions of Android users and technicians worldwide to flash firmware on MediaTek devices. Whether your phone is bricked, stuck on the logo, or you simply want to install a clean Stock ROM, this guide will walk you through everything you need to know. This step-by-step tutorial is for beginners and intermediate Android users who own a MediaTek-based Android device and want to safely flash their firmware using a Windows PC.
What is SP Flash Tool?
SP Flash Tool, also known as Smart Phone Flash Tool, is a free Windows application developed to flash firmware (Stock ROM) onto Android devices that run on MediaTek (MTK) chipsets. Repair technicians and Android enthusiasts widely use it to unbrick phones, update firmware, and remove software viruses from devices. You can find community guides and downloads on XDA Developers, the leading Android enthusiast forum. The tool supports a wide range of MediaTek processors including the Helio series, Dimensity series, and older MT65xx and MT67xx chipsets. It works with thousands of Android devices from brands like Tecno, Infinix, Itel, Xiaomi, Realme, Oppo, Symphony, Walton, Lava, and many more. The tool is completely free and does not require any registration.
Requirements / What You Need
Before you begin flashing, make sure you have the following items ready on your PC:
- A Windows PC running Windows 7, 8, 10, or Windows 11 (32-bit or 64-bit)
- SP Flash Tool — latest version (download from the link below)
- MediaTek USB Drivers installed on your Windows PC (Download MediaTek Driver Auto Installer)
- The correct Stock ROM / Firmware ZIP for your exact device model (must include a scatter file)
- A good quality USB data cable (not a charge-only cable)
- Your Android device with at least 30% battery charge
- A full backup of all photos, contacts, and files stored on your phone
If you are flashing a Xiaomi device like the Redmi Note 14 5G, make sure the Xiaomi Redmi Note 14 5G USB Driver is installed on your PC before connecting. This ensures SP Flash Tool can detect your MediaTek device correctly.
Warning: Flashing firmware will erase all personal data on your device. Always back up your important files before you begin.
Step-by-Step Guide to Use SP Flash Tool
Follow these steps carefully and do not disconnect your phone at any point during the flashing process.
Preparing Your PC and Files
Step 1 — Install MediaTek USB Drivers First
Before using SP Flash Tool, you must have the MediaTek USB Drivers installed on your Windows PC. Without the correct drivers, your computer cannot detect your phone. Download and run the MediaTek Driver Auto Installer, then restart your PC after installation. You can follow our full guide here: How to Install MediaTek Driver Auto Installer on Windows. Skip this step only if you have already installed the drivers.
Step 2 — Download the Flash Tool
Download the latest version of SP Flash Tool for Windows. The download is free. Once the file is downloaded, extract the ZIP archive using WinRAR or 7-Zip. Inside the extracted folder you will see several files, including the main executable file called flash_tool.exe. Do not move individual files out of the folder.
Step 3 — Download the Correct Stock ROM for Your Device
Download the Stock ROM (firmware) that matches your exact phone model number. Using firmware designed for a different model — even from the same brand — can permanently damage your device. The firmware package you download should be a ZIP or folder that contains a file named MT####_Android_scatter.txt (the scatter file). This file is essential — the tool needs it to load the correct partition layout.
Step 4 — Open SP Flash Tool as Administrator
Open the extracted folder. Right-click on flash_tool.exe and select “Run as Administrator.” This is important — running without administrator rights may cause errors or prevent the tool from detecting your phone. The SP Flash Tool main window will open with several tabs at the top: Download, Format, Read-back, and others.
Starting the Flash Process
Step 5 — Load the Scatter File
In SP Flash Tool, click on the “Download” tab (it is usually selected by default). Click the “Choose” button next to the “Scatter-loading File” field. Browse to your downloaded Stock ROM folder and select the scatter file named MT####_Android_scatter.txt. After selecting the scatter file, SP Flash Tool will automatically load all the firmware partitions into the table. Each row in the table shows a different partition of your phone — bootloader, recovery, system, and more.
Step 6 — Select the Correct Flash Mode
In the top-left dropdown, select the flash mode you want to use. Choose “Download Only” if you want to flash the firmware while keeping your user data. Choose “Firmware Upgrade” if you want to do a completely clean flash that removes all data and gives you a fresh factory state. For most users fixing a bricked or problematic phone, Firmware Upgrade is recommended.
Step 7 — Click the Download Button
Click the large green “Download” button (the downward arrow icon). The tool is now in standby mode, waiting for your phone to connect.
Step 8 — Connect Your Phone While Powered Off
Turn off your Android phone completely. Then connect it to your PC using a USB cable while SP Flash Tool is still open and the Download button has been pressed. SP Flash Tool will automatically detect your phone when it connects and will immediately begin the flashing process. You will see a yellow progress bar at the bottom of the screen showing the flash progress for each partition.
Warning: Never disconnect the USB cable while flashing is in progress. Do not press any buttons on your phone during this process. Interrupting the flash will brick your device.
Step 9 — Flashing Complete
Once all partitions are flashed successfully, a green circle with a checkmark will appear on your screen — this confirms the flash was successful. Disconnect your phone from the PC. Press the power button to turn on your device. Note that the first boot after flashing usually takes between 5 and 15 minutes. This is completely normal — your phone is setting up the fresh firmware. Do not panic or force restart during this time.
Common Errors and Fixes
Error: BROM Error – Com Port Fail
This error means the utility cannot detect your phone via USB. Make sure you have installed the MediaTek USB Drivers correctly on your PC. Try connecting to a USB 2.0 port instead of USB 3.0. Run the program as Administrator. Also temporarily disable your antivirus software, which sometimes blocks the USB communication.
Error: STATUS_IDENT_UNSUPPORTED – Auth Fail
This error usually means the version of the tool you are using does not work with your phone’s chipset. Download an older or newer version. Newer MediaTek chipsets such as the Helio G and Dimensity series often require a specific version. Check the firmware package for notes about which version of the tool to use.
Error: S_UNDEFINED_ERROR – Format Needed
This error means the phone’s internal storage needs formatting first so you can install the new firmware cleanly. In SP Flash Tool, go to the “Format” tab, select “Auto Format Flash,” and click the Format button. Once formatting is done, go back to the Download tab and try flashing again.
Phone Stuck on Boot Logo After Flashing
If your phone gets stuck on the brand logo after flashing, a partial flash or corrupted firmware file may cause this. Re-flash using “Firmware Upgrade” mode instead of “Download Only.” Also double-check that you downloaded the correct firmware for your exact model number.
Frequently Asked Questions (FAQ)
Is SP Flash Tool safe to use?
Yes. SP Flash Tool is a legitimate tool that Android repair professionals widely use. Make sure you download it from a trusted source and always use the correct firmware file for your exact device model to avoid problems.

Will using SP Flash Tool delete all my data?

Yes! SP Flash Tool is specifically designed to recover dead and bricked Android phones.
