Contacts – Sync with the Gmail application,
Call Log – Call Log and Restore

APN and MMS Settings – Note down from the path “Applications > Settings > Wireless and Network > Mobile Networks > Access Point Names

  • Minimum charge left in the device should be at least 70% so as to ensure that device doesn’t get turned Off in the middle of firmware update. ADB Should be installed in your computer without which it’s not possible to make use of this procedure.
