HELP PLS

Hello,
I need help.
Now I'm using 'S8500XXKK7.'
I'm trying to edit this firmware & I almost done it. Now, I want to add Facebook & Twitter (not in java) on the main menu screen. Anyone can give me these files to me & tell me how to add these files in firmware (CSC or FFS or ShpApp). I downloaded LEDFlashlite from the Samsung Apps. My default storage location is Memory Card & I see the installed files. But, I don't know how to add this files in firmware.
And I need to change the keyboard language to English (in system file, not in phone).

You can read that Facebook & Twitter apps for bada 2.0 are available for download for Wave I/II/III

So you can get them on S8500XXKK7 from Samsung Apps
Best Regards

deleting useless files (languages) from android possible ?

Hi there,
Just came from ios world and wanted to know if it's possible to delete unwanted keyboard and app language files (can be big..).
On iOS a simple script to scan XXX.proj (wich are the languages files) and so can slim down for good the phone.
As i can see some ppl made a custom slim ROM like 69MB on Gnex with only few languages.
Does someone know how to do it and if it's simple ?
Cheers,

the android rom is in /system, while the app u install go in /data

[Q] I´d like add new apps for all users on my tablets like sistem apps. it´s posible?

When I create new users, they can use all the stocks apps (Gmail, youtube, G+...). I´d like to add more apps to use for all the new users ( f.e. file manager, titanium,...) and remplace the sistem app that I don´t use for others more usefull for me.
I try to add one app to sistem/app, and I can find it like a sistem app with Titanium, but it not appear on the rest of the users...
How can I do it? is posible?

How to uninstall theme?

I tested some themes from SmartWorld and decided that they are not useful. How can I remove them from my device? I already searched in the list of installed apps, but couldn't find anything with a matching name.
