Sadly somehow my backup file isn't working. Worse still was that I can't find the the stock rom zip file to download. I managed to find and downloaded one, which is ver. 4.2.2 thinking that I could update it via kies after flashing it into my phone. So I wipe data and use Odin to flash, but apparently it FAILED :'( so now my phone says something about firmware update failed and was ask to use kies recovery. Another thing was kies can't connect my phone, kies 3 says it couldn't support my phone. This is some real ***, sorry for the cuss
