This is very simple to do, really.
First, download SuperOneClick (thread here: http://forum.xda-developers.com/showthread.php?t=803682
) and place it on your desktop.
Next, on your phone, go to Settings -> Applications
and enable Unknown Sources
. Next, go to Settings -> Applications -> Development
and enable USB debugging
You also need the proper USB drivers. To check if you have them, start SuperOneClick.exe and click Driver Check. If the driver check fails, update your phone with PC Companion.
Now, connect your USB cable from your X8 to your computer. When connected it is VERY IMPORTANT
to select CHARGE PHONE
. Really, I can't stress this enough.
Start SuperOneClick.exe and just click ROOT. Everything should go normally. You might get a message asking you if your OS is 2.0 or higher, just go ahead and click Yes.
You should now be rooted!
YOU MUST BE ROOTED TO DO THIS
Installing xRecovery is the first step in the world of custom ROMs. Installing xRecovery also means if you are stuck in a bootloop, you can just recover to a working backup.
The first step is to download xRecovery mini-beta 0.1 (any other version WILL NOT work on your X
(download HERE: http://www.megaupload.com/?d=8AJTKDTQ
Next, download Root Explorer (download HERE: http://www.megaupload.com/?d=LGC110EX
Copy both the xRecovery folder and the Root Explorer .apk to your SD card.
Install any file manager from the Android Market (I recommend OI File Manager or Astro) and use it to browse to the Root Explorer .apk file and install it.
Run Root Explorer, browse to the xRecovery folder and copy the 3 files inside onto the /system/bin folder.
xRecovery is installed. To start xRecovery you press the Back button while the Sony Ericsson logo is showing during boot. Restart your phone and just keep pressing the Back button.
To move around in xRecovery you use the volume buttons, to select an item you press the Home button (the middle one), and to go back you press the Back button. Go ahead and make a backup of your current system (make sure you have at least 300MB of free space on your SD card.
You'll find the backup you just made in the xRecovery/backup folder. Name it something you can identify (don't use spaces). Copy that backup onto somewhere safe on your PC.
