How to Downgrade Galaxy 3 i5801 to Eclair DDJG6 2.1 Firmware

Samsung Galaxy 3 LogoAfter last time when we saw on how you can upgrade Galaxy 3 I5801 (APPOLO) firmware to Froyo 2.2 version, many of the users complained about non-working of Live Wallpapers, Chinese scripts in some of the core phone applications which many users couldn’t get rid off. So, since now you have tasted the Beta version of Froyo and for the users who wished to go back to the Indian version of original firmware we will guide you on how you can again go back to the stable ROM of DDJG6 2.1 version which is official Eclair version from Samsung Electronics. Please ensure that if you are having only complaint of non working of Internet then the problem is not in firmware, you will have to configure your Internet Settings which can be done by configuring the APN Settings which will be there in the Wireless & Network Settings. Before proceeding to downgrade from the current 2.2 Froyo version ensure that you follow the instructions carefully and it will take hardly 5 minutes to downgrade the software from the current Froyo 2.2 to the Eclair 2.1 version.

To check on which version you are on then you will have to just tap on the Settings > About Phone > Firmware Version where you will find the version of Android OS where it will show 2.2.
  • Also, most importantly since the firmware update process will wipe all the contacts, sms, third party applications, music, images and videos you will have to ensure that you have taken a backup of all your content so that you can easily restore them.

Also, additionally ensure that you close all antivirus applications, firewalls etc. before opening KIES as this may interrupt the updation process and make sure that your computer or laptop has a supports USB 2.0.
