Fastboot problems- Unlocking the bootloader

Elnano26 — Sun, 16 Feb 2014 20:59:18 GMT

Good evening everyone I am writing to a problem with my phone (hoping to solve), as the title suggests I would like to unlock the bootloader of my phone but my phone does not go into fastboot mode. As soon as I click the volume + button, the LED will light up blue for a few seconds, but then returns to red and the phone restarts, how can I fix it? Has anyone had the same problem? Thanks in advance for a possible answer! :smileysmileywink:

Are you using Win 8 or 8.1 or a 64 bit based system - Also look in the Fastboot folder if you installed it for the alternative drivers

Also are you able to unlock your Bootloader as the phone will not stay in Fastboot mode

Excuse the delay in response, for a few days I have had the internet, however, I resolved, at the beginning I wanted to unlock the bootloader with windows xp but with this software cellualre not connected in fastboot mode, then I tried it on my other computer with window7 64 bit and it works. Thank you also for the help! :smileysmileywink:

Hello, I have recently decided to try and root my phone to use certain apps such as titanium backup, and I have become stuck on step 3... I have installed the android sdk, I have Eclipse Juno, and downloaded the fastboot driver and replaced it, yet when I attempt to press the voume up button, at the same time as plugging in the usb nothing shows up and I have yet to find any answers that helps with this. If anyone could help me out I would appreciate it. I am using windows 7 OS and I do not know how to get past this section:

Connect to Fastboot

Turn off your Xperia™ T.

Connect a USB-cable to your computer.

On your Xperia™ T, 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.

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

Enter the following command: fastboot devices

Verify that you get an answer back without any errors.

Same issue for me; Windows 7, 64-Bit. My PC makes the double "bong" sound and in Device manager, it appears that I don't have the correct driver installed. My Z2 light does stay blue, however.

How do you find the Fastboot folder? Sorry if this is a really dumb question, but I'm stuck at this point. I've downloaded the replacement file, no problem, but I can't find the original. The filepath specified on the developers website doesn't seem to exist!
