[Sony Xperia M2] ionescu.gabbriel:
Hey guys, anybody with locked bootloader managed to unlock it? I`ve tried the method from sony but doesn`t work, i get stuck at fastboot devices command. My M2 Aqua has locked bootloader and is not in Sony list for unlocking, so i choosed M2 for getting the code.

Sony says to follow this steps, witch i did but at point B step 3 got a bit lost because of this" select the Android Boot loader Interface-file"; i pointed to that usb_driver dir and it just instaled. Please a little help here:

------------------------------

A. Install the Android SDK and the device drivers

1. Download and install the Android SDK.

2. If you’re running Windows, you also need to download and install an updated Fastboot driver. This is the standard android_winusb.inf-file, with a few lines of code added to enable Fastboot to support Sony & Sony Ericsson devices. Replace the original android_winusb.inf-file with the downloaded file in the usb_driver folder, located in the Android SDK > extras > google folder on your computer. If you can’t find the usb_driver folder, make sure you are running Google USB Driver package revision 4 or higher in your Android SDK. If not, install the Google USB Driver Packager using the Android SDK manager.

Note! If you’re running OSX or Linux, you are not required to install any additional drivers.

3. On your device, turn on USB debugging by going to Settings > Developer options and click to enable USB debugging.

As of Android Jelly Bean 4.2 the Developer options are hidden by default. To enable them tap on Settings > About Phone > Build Version multiple times. Then you will be able to access the Settings > Developer options.

B. Connect to Fastboot

1. Turn off your Xperia™ M2.

2. Connect a USB-cable to your computer.

3. On your Xperia™ M2, press the Volume Up button at the same time as you connect the other end of the USB-cable. For Windows users, when asked for a driver, point to the usb_driver folder where you placed the android_winusb.inf-file, and select the Android Boot loader Interface-file.

4. When your device is connected, open a command window on your computer and go to the platform-tools folder within the Android SDK folder.

5. Enter the following command:

fastboot devices

6. Verify that you get an answer back without any errors.

C. Enter unlock key

WARNING! The command below contains your unlock key. If you perform this step, you will unlock the boot loader. This may void your warranty and/or any warranty from your operator.

1. If you still want to unlock the boot loader of your device, enter the following command:

fastboot -i 0x0fce oem unlock "my unlock code"

2. Verify that you get an answer back without any errors.

D. Done!

You have now unlocked the boot loader of your device. Return to Developer World for the latest developer news from Sony.
