Hi, welcome to my first tutorial. Though this tutorial is specifically for Sony Ericsson Live with Walkman (WT19i), since I own it, this method may work with other SE phones. And since this method doesnot unlock the bootloader, you may not loose your warranty. So Let's Start: You need to download about 500mb of files. Ready ? I MUST NOT BE HELD RESPONSIBLE FOR ANY PROBLEM YOU FACE IN YOUR MOBILE AFTER FOLLOWING THESE STEPS. Backup all your data, sms, contacts, pictures etc, and your memory card too. Note: Some processes maynot be reversible. DOWNLOADS 1> Download Sony Ericsson PC companion. This will provide you many necessary drivers. 2> Download this version of firmware 4.0.2.A.0.58. This is the prior to the latest version of Gingerbread and is rootable. 3> Decide what you want after rooting, you want ICS or Gingerbread. If you want Gingerbread, download this firmware 4.0.2.A.0.62 If you want ICS, Download this firmware 4.1.B.0.431 Note: Only download the firmwares suitable for your phone model only. Links provided here are for Live with Walkman WT19i. 4> Download FLASHTOOL for windows. Google search, you will easily find it. 5> Download DooMLoRD_v4_ROOT-zergRush-busybox-su. Google exactly. You will find it. 6> Download Xperia-ROOT.rev3.zip NOW THE STEPS 1> Install Sony Ericsson PC companion. 2> Go to phone Settings menu and set connectivity mode to MSC (mass storage), enable unknown sources (in application settings) and enable USB debugging. TURN OFF YOUR PHONE AND DO NOT PLUG IT TO YOUR COMPUTER. Your phone should be at least 60% charged. 3> Install flash tool in C: drive. Now open it and run flashtool.exe 4> Extract the firmwares 4.0.2.A.0.58, 4.0.2.A.0.62, 4.1.B.0.431(ICS) in the Firmwares folder 5> Install ADB drivers. The installer can be found in the drivers folder shown in the picture below. Select all. 6> Click the Z looking icon as shown in the picture below and select Flashmode in the popup. Ok 7> Select the firmware version 4.0.2.A.0.58. Tick wipe data, wipe cache and wipe apps log. (You face some problem if you don't tick all, I faced it. Some apps crash) Then press OK. This will take some time relax till a popup menu appears. Note: Your C: drive should have at least 400 MB free space. Since it decompress the firmware images. 8> Now press the volume down button which your phone is Switched OFF. Donot turn it ON. Plug the USB cable while holding the volume down button. The LED must glow green. MUST GREEN !!. If not, repeat the steps. The phone will not be detected and firmware installation process will start. Donot interrupt. Let it take time. Just waitafter finish, disconnect the phone and switch it ON. It will take much longer time to turn on now. But wait. Donot interrupt or you may damage your mobile. 9> After this, follow on screen instructions and may or maynot set date time etc. 10> Now extract DooMLoRD_v4_ROOT-zergRush-busybox-su to C: drive and run runme.bat. Some zerlings, some scootings will go on. Let it be. Follow the onscreen instructions. 11> Now extract Xperia-ROOT.rev3.zip to C: drive and run 01-local-prop.cmd 12> Turn off your phone. Repeat steps 7, 8 and 9 but this time donot select 4.0.2.A.0.58 And donot tick Wipe data ! ! 13> Almost done. Now run 02-push-root-files.cmd from the Xperia-Root folder. HURRAY !! Your phone is now rooted. This superuser app must be visible now if rooted. You can install root checker to check if rooted or not. Install Busy Box installer from Google Play and install busy box. And the best part is you have not even unlocked the Bootloader.
