Before we begin our rooting business, please follow the hints given below.

1. Don’t forget to back up your data. If you have synced the device with a Google account, then the contacts, calendar, Gmail, & select other Google-related data will not be lost and will come back after the next sync. However, you should backup anything you want to keep that is not stored on the SD card:

It would also be a good idea to backup everything stored on the SD card in the rare case the SD card must be formatted to resolve any major problems.

MyBackup RootSMS Backup & Restore, and Call Backup & Restore are all free applications that can assist with backing up your data.

2. Make sure that Samsung Kies is installed on your PC. If not, Download and install the Samsung USB Driver: Download

3. Make sure that your phones’s battery level is not less than 70 percent.
