Today morning when I unlocked my mobile software update notification was popped. I thought this might be Jelly Bean Upgrade! Not really but it’s a firmware update. Nothing special described about the update, they asked
this upgrade is to improve phone’s stability
. That’s all.
How to update Samsung Galaxy S Duos’ (GT S7562) Firmware?
Make sure that your phone’s battery is fully charged. You can update through WI-FI or 3G whatever. I have used my mobile’s 3G internet. To start the update process, navigate to settings -> About Device -> Software Update. If you wish to use 3G data then untick the WI-FI option and click check for update. It will notify you about the update, proceed with the download: total file size is 16.97MB. Once downloaded, your phone will reboot in “BOOT” mode and install the software by itself. Don’t remove the battery or sd card during the installation, that may brick your phone. Once update is complete your phone will reboot again and start in normal mode.
Your personal data, call logs, messages everything will intact and the whole process gonna take 10~15 mins depending on download speed.
