[TUTORIAL]Up/Downgrading, ReFlash/ing, Rooting/xRecovery[For Noobs ONLY]

What is Rooting? and what are the benefits Rooting my device?

Let me tell you why.

What Is Rooting?

First of all, for the newbies, let me define what rooting is. Getting root or 
rooting your phone is the process of modifying the operating system on your
device which will grant you complete control over it.

This means you can overcome limitations that the carriers and manufacturers
put on your phone, extend system functionality, and even upgrade it to a custom flavor of Android.

The name root equally known as Administrator on Windows is called root.

Benefits Of Rooting

Full Control Over Android
1. Back Up The System
2. Save Space On Your Phone
3. Move cache data to SD card 
4. Move installed applications to SD card 
5. Install Custom ROMs & Themes
6. Run Special Applications:
some of application that needed rooting access
# Super User – allows you to approve or deny root access to any application
# Auto Memory Manager – kills tasks you wouldn’t be able to otherwise
# Move Cache for Root – move cache for browser, market, maps, street view, 
and gmail onto SD card
# Startup Manager – Clean up android system from system startup to boost 
system power and memory from the get go
# SetCPU for Root Users – Overclocking your rooted device lets you speed up
 your phone’s processor when you are using it and lets you slow it down when it
 goes into "sleep" mode. It can either be a battery hog or battery saver.
# Root Explorer - working as file manager, where you can manage file not only
 on sd card, but also in system files.
# Rom Manager - which allows you to easily flash a custom recovery image
 which is what you will need in order to backup and restore your phone.

What is Flashing, Downgrading & Upgrading??? are you retarded?:D

I don't think i have to explain these more details cause eventhough you're noob.
anyway i'll just explain it in simple way.

0. Flashing are the universal word for Downgrading and Upgrading and installing. 
(thats the way im using the word for flashing.)
(eg: im going to flash the old firmware/ the latest firmware/the awesome 
Sony Blues Theme/ the Froyo ROM.)
1. Downgrading is the proccess where you're reverting your android baseband 
and
firmware to the old version.
2. Upgrading is the proccess where you're going to update your baseband and 
firmware to the latest version.
3. Both of the proccess above can be perform with Flashtool and Sony Ericsson 
Update Service(you can't downgrade using SEUS)

Nujhum Sensei, i got couples of question.
1. What is Flash Tool?
-FlashTool now is something like an all in one Tool for your phone.
It can:
- Flash original Images (Android 1.6 & Android 2.1 Images)
- Root your phone (Only if the phone is on a 2.1 android version)
- Install xRecovery, Busybox
- Clean your Rom (remove /system/apps apps of your choice)
- Clear dalvik cache
- Optimize (install of JIT v2)
- Customize (installs apps found in the custom/apps folder of the flashtool)
- Clean uninstalled (remove any references to system apps removed in the Clean (root needed) step)
- Edit /system/build.prop

2. What is Sony Ericsson Update Service (SEUS) ?
-Sony Ericsson Update Service (SEUS)
It can:
-Update your phone for optimal performance and get the latest enhancements.
-Regardless if you have the latest software, it is a good routine to run Update 
Service to improve software stability. 
-Also, if you experience problems with your phone this may be solved by a software update.

i.  bricked devices
- normally a bricked device happened on the proccess of installing/flasing 
custom ROMs and Themes, Down/Upgrading using flashtool and etc.(i only 
experienced all those i've stated).
- most problem you'll encountered whith bricked device are, endless loop 
reboot, loop reboot and can't load xRecovery and else. :D
- and when it happen.
- "MOM, i killed my phone that daddy bought for me last week. he's going to kill 
me". DONT WORRY, THERE'S ALWAYS HAVE SOLUTION TO EVERY PROBLEMS.
- You can always flash your device using Sony Ericsson Update Service (SUES).
 which i've include where to download and how to use it in the 3rd step of 
Flashing/Down/Upgrading Tutorial.

ii. waranty void
- the most critical part, at least the most of you guys will think after rooting,
 xrecovery, installing custom room now your waraty are void.
- why? because Sony wont like it when we messing up with their device.
- don't worry you can get it back by flashing it using, yes, again using SEUS.

This is the starting point of getting your warranty void.
What you're going to do here is Rooting your phone,
and make your android do something amazing that Superman can't.
Refer to ABOUT SECTION #1.

The second step after Rooting your android, are having xRecovery install to your android.
Refer to ABOUT SECTION #2

This is where you're going to flash with different version of baseband and
 firmware.
Unbrick a bricked devices.
Some custom ROMs need certain baseband and firmware, and this the how you'll
 do it to change baseband and firmware.
