Hey, I use a w580i, and I need to know where the java game data are (I saved the game in mem stick... could it be there?). Im planning on flashing, and I don't want to start my games all over again. Also please tell where the fitness application walking/running data are. Thx

You'll lose your games kept in memory card or phone memory if you reflash it.

However there is one way which i haven't tested but i expect it to work.
Move ALL the games you play to Phone memory.
And backup EVERYTHING present in tpa/preset/system/ams

Then perform the flashing and restore all the files back to tpa/preset/system/ams

An easy way to backup would be to use Access FS via Java patch and use MiniCommander to copy the whole folder.

Thanks for the help!
