Need help [Samsung Keyboard]

I was trying to change my keyboard but i ****ed it up all and now i can't got back my default keyboard :C
so i hope you can help to find these files:

SamsungIME.apk and SamsungIME.odex, both from /system/app
libswiftkeysdk-java.so, from /system/lib

I need 'em for a Galaxy Tab 4 SM-T230 (7"). You need be a root user to get these files.

I really need it, i'm using the Google Keyboard and it sucks, i miss my stock keyboard :C

Thanks you <3
