But in my mobile kies app is installed. I believe it is Kies.
Download Kies for pc ('Kies3' if you were using android 4.3 version, otherwise downlad 'Kies'),
plug your device to pc (while in recovery mode), let it be recognized by kies, go to Tools->Emergency firmware recovery, and let it do its magic.
(Be advised that i never tried this method before, so it could potentially delete all your data from device )
Other method is using Odin app. Choose the wanted firmware for your country from: http://www.sammobile.com/firmwares/1/
and follow this guide: http://forum.xda-developers.com/show....php?t=1671969
Note that in this method you'll see all your files intact (so its a good time to backup), but in order to avoid any version merging issues, you should do a 'wipe data/factory reset' + 'wipe cache partition' while in recovery mode.
