Pertama keadaan awal XS harus dalam fw GB dan GBnya terserah yg mana aja boleh jadi yag udh ICS silahkan downgrade dulu

Download ROOT TOOLKIT 1.0.1[URL="http://www.media*fire..com/?nrq4t17p98wwn8z "]disini[/URL]
Atur XS agan kyk dibawah ini

(2) Application Settings: Development [USB debugging] checked {Allowed}

jangan sampe layar XS agan mati takutnya ntar ndak komplit proses rootingnya

StepByStep
1.Tancepin XS ke PC lewat USB pastikan settingan diatas sdh dilakuin semua
2.trus ekstrak Rottoolkit tadi dan buka folder didalmnya ada step1.bat dobel klik ntar keluar CMD tekan aja enter sampe selese
3.trus flash XS sama FW Generic CH (1257-3740) XPERIA S LT26i ROM (6.1.A.0.452) yg tdi udh di donlot

kalo udh selese flashingnya tutup jendela flashtool lalu nyalain XSnya
4.kembali ke folder root toolkit tadi dobel klik step2.bat ikutin smpe selese
NB:klo udh selese execute step2.bat ntar XS gak bakal ngecharge meski di tancepin ke PC(tpi di kasus ane tetap ada tanda petir di batre )
5.habis itu bka flashtool lagi flash XS dengan fw GB ato ICS yg agan pke klo ane sih prefer ICS (ane pke generic CH sama seperti langkah 3 jadi ndak 2 kali donlot)
setelah selse sekali lagi tutp flashtool dan nyalain XS agan.kalo misalkan keluar “acore process closed (stopped working) unexpectedly”tutp aja ndak apa (tapi di ane ndak terjadi XD)
6.tancepin XS lagi ke PC trus dobel klik step3.bat di foldr root toolkit tadi ntar keluar CMD ntar setelah agan pencet enter tunggu smpe selese di ane cman 1 detik lgsng nutup sendiri CMDnya jdi ndak usa takut
7.dobel klik step4.bat(munkin ntar XS agan akan Reboot tpi di ane ndak kok jdi klo msalkan XS agan ndak ngereboot ndak apa )tekan enter utk nutup jendela CMD, lanjutin dengan dobel klik step5.bat ikuti smpe selese
