Yesterday during my classes my friend asked me "how to root my device". then I thought that there must be many who still dont know how how to root the android. So, I am here with some easy steps to help you out with ROOTING or UNROOTING your android.
1) UPD_1.ZIP(download link in the end)
2) USB (for those who will transfer files from PC otherwise you can directly download it on android)
3) basic knowledge about rooting.
STEPS TO ROOT YOUR DEVICE:
1) PUT THE "upd_1.zip" on your SD card.
2) turn off your phone.
3) Enter recovery mode by holding Home+Power-buttons at the same time.
4) Use the volume key's to scroll through the menu. Select'Apply update from sd-card'(Could be something else, but looks like this.) Use the home button to apply function.
5) Use 'Select zip from sd card' to find upd_1.zip on your SD-card.
6) When it asks you if you wanna apply the update, select yes. Use the home button to confirm.
7) Wait for it to finish, then reboot. Your phone is now rooted.if you want superuser elite visit here.
