About the application BQ Firmware Flash Tool

The application BQ Firmware Flash Tool is developed by BQ to allow any user to easily flash a mobile device.

This operation, also known as a hard reset, restores the device to its factory state and installs the latest version of the firmware available for your device directly from BQ’s servers.

The flashing process means that all data, music, photos, applications and settings stored on the device will be deleted. Before using the Flash Tool, you need to save any files you want to keep onto your computer, hard disk, cloud, etc.

Unlocking the phone startup manager

For security reasons, your smartphone is preconfigured not to allow flashing. To complete the flashing process you first need to adjust some settings. More specifically, you need to unlock the phone startup manager. Below are the steps to follow for phones running the Android OS.

If the status of your device does not allow you to carry out the process laid out below (for example if the device doesn’t start up correctly, or because the touch function doesn’t respond) skip this step and go directly to the next section: Flashing the device.

  1. In Settings, go to Developer By default, this option is hidden in the menu, so you will probably have to unhide it. To do so, go to Settings and select About phone.
  2. Now go to Build Press Build number repeatedly to unlock Developer options.
  3. Developer options will now appear in Select it and access the menu.
  1. Enable the option OEM

Your phone is now ready to be flashed.

  1. Connect the device to the PC using the USB cable. The application will recognize the device, automatically detect its series number, and show it in the Click Connect to the device.

It is possible that the serial number of the Aquaris M5.5 is not detected properly causing an Unknown device message to be returned when the Connect device is pressed. Press Enter Serial Number and space will open in which the serial number, found on the back after the letters (S/N:), can be entered manually. Press Retry once entered.

After each reboot, the device remains in normal mode. Without disconnecting the smartphone from your PC, turn the smartphone off and then in FastBoot mode turn it back on (see step 2). The application detects the device again and continues the process until the unlocking process is finished.
