Phone Contacts – Sync with the Gmail application,
Call Log – Call Log and Restore
Pictures, Music, Videos, Files etc.– Copy to internal / External SD Card,
Internet & MMS Settings – Backup all the settings from the path “Applications > Settings > Wireless and Network > Mobile Networks > Access Point Names”
- Charge left in your device should be a minimum of 60% so that your phone doesn’t give up in the middle of firmware update.
- Enable the USB debugging in your Samsung Galaxy S2 GT I9100 phone from the path “Settings > Applications > Development > USB debugging”. The USB Debugging option should be ticked.
