How can I backup all my games/apps from memory phone installed? Just copy tpa/preset/system/ams folder before updating and paste after? Or other method to do this? Copy to memory card?

You can copy the games to a memory stick, and take it out during the update. Like this, all your games will stay on the memory stick, and won't be deleted during the update process !

Thx a lot, I'll check it out soon

It don't works, lost all my apps/games :x ;(

Did you actually move all your games to your memory stick, and then take it out? Because if you actually did like I told you, you still would've had your games.

Oh, and for the record, the smiley isn't ;( but it's -:-c-r-y-:- , just remove the dashes to use it

Or why not save them with A2uploader

I've got files in card/system/ams. What should I do with them? Copy to phone/tpa/preset/system/ams?

Yes press read and they will be in PH_OUT folder

And what now? I don't won't to have only a .jar files, I want to have all saves & settings!

You cant keep the save games and that
