It remains to install drivers and prepare the PC completely for the process:
- We download and install the latest (important) version of the Android SDK, if we don’t already have it. We can find it on the official Google page.
- We download and decompress the Sony file that allows us to use Fastboot with the devices of the Japanese company. This file is downloaded from the Sony page. It is important to note that the Android SDK must have the Google USB Driver package revision 4 or later.
- The decompressed file will replace a file in the SDK itself. To do this, we access the hard disk (C :), open Program Files (Program Files), and then enter the folder called Android. From here, we access android-sdk> extras> google> usb_driver. And here, we replace the android_winusb.inf file with the file with the same name we just unzipped. If we cannot find the usb_driver folder, then we will have to install Google USB Driver Packager using the Android SDK Manager (in the “android-sdk” folder). First, we will install the Android SDK Tools package, and after restarting the SDK Manager, we can search for the Google USB Driver Packager package. Once we have installed the Google USB Driver, we can copy the file to the folder indicated at the beginning of this step.
- Now, we download Fastboot for Windows, unzip,
- Turn off the Xperia and disconnect it completely.
- Then, connect the USB cable of the mobile to the PC first.
- Press the unlock button (volume up) of the Xperia, and connect the phone to the computer while still pressing the button. The blue LED will turn on.
- While connected with blue light we are connected in fastboot mode. It is important to perform these steps quickly. If the mobile has stopped having the blue light, we disconnect, and reconnect as explained.
- Before connecting the mobile, you must open the Windows device manager. In Windows 7, we find it in the Start Menu, in Devices and Printers. Both with one name and another, it is very easy to find.
- Now we connect the mobile, and wait for S1Boot Fastboot to appear. We open it quickly, since we can only do it for a few seconds. Once opened, it does not matter if the mobile exits the fastboot.
- We go to the Hardware tab and click on Properties.
- Once here, click on the Controller tab, and select Update driver …
- Select the manual option, and look for the folder that is in the path C: \ Program Files \ Android \ android-sdk \ extras \ google \ usb-driver. Click on Accept.
- Whatever the notices, we continue with the process. Automatically it will do the rest, but if it were not yes and it gave us to choose between several options, it would be necessary to select “Android Bootloader Interface”. In the latter case, before clicking Next, it will be necessary to disconnect and connect again in fastboot mode. It is possible that this last step is automatic and you do not have to do anything.
- Once finished, we will have the drivers installed and everything in perfect working order. If the blue LED still does not remain, try disconnecting and connecting several times before trying to repeat the entire process.
