OK so i was looking around for a easy to use guide i could refer someone to and couldn't find one so i decided to create 1.
With this method you wont need to download the android SDK and instead can download a small package of files that i will upload. this saves around 1-2GB of bandwidth.
Firstly we should confirm your phone can be unlocked. To check if your phone can be rooted (most likely if it is not branded to 3, Vodafone etc then it can be)
Go to the phone dialer
Tap*#*#7378423#*#* then a service menu should pop up,
Tap Service info > Configuration > Rooting Status. if it says boot loader unlock allowed then you are good to go.
if it says not allowed or no then you will need to pay to have the boot loader unlocked.
Now we need to get your IMEI to do this type in the dialer *#06# another window will appear with your IMEI number write this down somewhere as you will need it later.
OK so now that you know your phone BL can be unlocked we will need to download and extract these files
- ADB and Fastboot Package - http://db.tt/B5vG1yn
if something doesn't happen like it is suppose to please reply here or pm me.
Next we need to go to sony ericsson's bootloader unlock site read through to confirm you understand what your doing then click continue.
Click "yes i'm sure"
ok now check both boxes and press i accept
now we need to fill in these fields (IMEI is the number you wrote down earlier if it doesn't work remove the last number and try again)
Press submit and you will see your Unlock Key copy it for later.
Finally after installing the drivers we will need to run the software called fastboot now to make it easier for you guys i have included a simple bat file which will load CMD at the correct location. so load run_me.bat and make sure the BLUE LED on your phone is still on. if it is then type this in to the new cmd window.
fastboot.exe -i 0x0fce oem unlock 0xKEY
fastboot.exe -i 0x0fce oem unlock 0x726802F75671552D
