The official Froyo update for G3(indian build – DDJP2) has been available since April through the Samsung Kies desktop software.. however its quite slow and fails often due to the size of the update, and the number of people connecting at a time for the update. Hence i just did it manually using Odin and the tutorial at this link – odin-installing-22-froyo-ddjp2
Result: works great.. and quite stable so far. the one big issue is that the swype keyboard is non functional 😦 ,there is a tutorial on how to uninstall and reinstall to get it working – getting-swype-working-on-i5801ddjp2
big news: Rooting works! Root your phone with Super One Click from here.
The more convenient Z4root doesn't work, i tried 😦
Anyway, and so i was able to re-enable live wallpapers again 🙂 🙂 🙂 go here for the instructions
