How to root Xperi Tipo (ST21i)...

First of all everybody has to know how to root a Sony Xperia Tipo.
If you want to get more information about what is rooting you can find here!


SOFTWARES YOU NEED:

#First software you need is the Sony PC Companion (mirror)
Install it, because it contains the necessary drivers for your computer.
#You need Flashtool (mirror)
#OLD Firmware for tipo (mirror)
#Root with restore v18 by Byn4ry (mirror)


So let's ROCK!

Step1

Open Flashtool (after installed), i assume that you already installed Sony companion software to your PC, so that Flashtool can detect your phone. (Maybe you shoud click on sofware update of your phone and at the last step you can go back if you see that the drivers installed correctly.)

Enable debugging mode on your phone (Setting>developer options) & enable unknown sources (Setting>security)

Connect your phone with usb, and if prompt to select your device

Click Flash icon (looks like thunder) and choose flashmode

Then browse the folder where you save the Old firmware (.ftf) file . Flashtool will automatically scan files inside the firmware.

Click OK

Step2

• Flashtool will ask you to disconnect your phone
• Disconnect your phone and shut it down
• Push Volume Down (-) button (dont release it) and connect the usb cable again
• Until Flashtool say your phone connected in flashmode then you can release the button
• Let it finish and turn on your phone (it takes awhile to turn on)
• Enable debugging mode on your phone (Setting>developer options) & enable unknown sources (Setting>security)

Step 3

• Extract  Root with Restore by Bin4ry you downloaded before, and make a folder called root in Drive C: then copy all the stuffs extracted into the root folder
• Run Command Prompt as administrator (For Windows 7 search at start and right-click CMD run Administrator/ For Windows 8 push button windows(this button below Z) + X then select command prompt (Admin))
• Type “cd c:\root” without the quote (“”)
• Type “stuff\adb devices” without the quote (“”)
• If your device connected properly, it should be there (For some PC there will be more devices because you install Bluestacks/You Wave. and you need to uninstall them otherwise it wont work)
• Next type “runme”
• Green message will come out, type “1″ then enter
• A message will come out in your phone, ignore the password encryption. Just select Restore My Data option
• The Green command prompt will assist you, if the message stuck on Running for so long, mean you fail to root. (Fail happened when you skip step 1 or your firmware is new)
• After finish, your phone will reboot and there will be new application installed called Super SU
• Gratz! You phone rooted!
