1. Verify Connection: Type the following command to ensure Windows sees your phone:
fastboot devices
If you see a serial number, you are good. If the list is empty, your drivers are not installed correctly.
2. Unlock Bootloader (IF REQUIRED): If you are flashing an official update intended for your specific variant and the bootloader is already locked, skip this step. If you are downgrading or flashing a custom ROM:
fastboot oem unlock
Follow the instructions on the phone screen to confirm. This will wipe all data.
3. Flashing the Images: The method depends on the file type.
Scenario A: Flashing a Script (common in older Bq tools)
If you downloaded a pack containing a flash_all.bat file, simply double-click that .bat file while the phone is connected in Fastboot mode.
Scenario B: Manual Flashing (Standard method) You must flash partitions one by one. Do not mix up these commands or filenames.
4. Reboot: Once the flashing is successful (you will see "Finished" or "OKAY"), reboot the device:
fastboot reboot

Core Functionality: It allows users to perform "Firmware Upgrades," "Download Only," or "Format All + Download" operations using a scatter-loading file.
Reliability: When used correctly with the official scatter file, it is highly effective for unbricking devices that won't boot normally. Critical Usage Tips for Windows 10
Driver Installation: You must install the MediaTek VCOM drivers first. Windows 10 often requires you to disable Driver Signature Enforcement to install these successfully. Hardware Connection:
Use a USB 2.0 port if possible; many users report that USB 3.0/3.1 ports can cause connection timeouts or flashing failures.
Connect the device while it is powered off. Sometimes holding the Volume Up or Volume Down button while plugging it in is necessary for the PC to detect the VCOM port. Risk Mitigation:
Always untick "Preloader" unless you are performing a full recovery, as flashing an incorrect preloader can permanently hard-brick the device.
Select "Firmware Upgrade" instead of "Download Only" when moving between major OS versions to ensure all partitions are updated correctly. Review Summary
Pros: Essential for recovery; provides deep access to system partitions; free to use.
Cons: High learning curve; picky about USB ports and cables; can brick the device if the wrong settings or firmware files are used. AI responses may include mistakes. Learn more

The story of the BQ Firmware Flash Tool on Windows 10 is one of a once-pioneering Spanish tech company whose legacy now lives on through community-driven archives. Originally, BQ (Mundo Reader, S.L.) used these tools to support their diverse lineup, including world-first Ubuntu-powered smartphones like the Aquaris E4.5
Today, since the official BQ website went offline in 2019 following the company's eventual bankruptcy in 2021, users must rely on third-party collections and specific manual procedures to keep these devices running.

chipsets (such as the E and M series), the "BQ Flash Tool" is effectively the Smartphone (SP) Flash Tool Firmware Archives:
Because official servers are gone, developers have re-uploaded stock ROMs to community repositories like GitHub to prevent them from being lost forever. The "Scatter" File: Flashing requires a specific text file (e.g., MTxxxx_Android_scatter.txt
) found within the firmware folder, which tells the tool how to map the new software onto the device partitions. johncanning.net Windows 10 Compatibility Challenges
Using these legacy tools on modern Windows 10 systems requires overcoming several security and hardware hurdles: Driver Signature Enforcement: Windows 10 blocks the installation of the necessary VCOM drivers by default. Users must manually disable driver signature enforcement
through the "Advanced Startup" menu before installing the drivers. USB Port Issues: The SP Flash Tool often fails when connected to USB 3.0/3.1 ports
