I agree with Tromatic. If you are still having problems, forget custom ROM or recovery, just go back to factory using ODIN. But...

Since you already have a French ROM with 4.4.2, you need to use a Turkish ROM in 4.4.2. Unfortunately, the only Turkish ROM available on SammMobile is 4.2.2 ROM (which Tromatic kindly provided a link above). It is unclear whether we can flash a ROM with an older version using ODIN. So you need to try it and find out.

Flashing of factory ROM is best done using ODIN. To begin, you need to make sure that ODIN is working.

You need a Windows computer, with the proper Samsung driver installed. Also search and download Odin 3.09, and have it ready to run.

The Turkish 4.2.2 ROM is linked in the post above by Tromatic. Download that.

To use ODIN, follow this guide:

Step 1. Power off your tablet and hold down Volume Down, Center Home, and Power button together for about 5 seconds.

Step 2. When you see the warning screen, hit Volume Up button to enter ODIN Download mode.

Step 3. Connect a micro-USB cable from your tablet to your computer.

Step 4. Download and run ODIN 3.09 program.

Step 5. Unzip the stock firmware, you should find a file ending in “tar.md5″. That is the stock firmware you will flash using ODIN.

Step 6. DON’T TOUCH ANYTHING ELSE but hit the PDA button, select the stock firmware “tar.md5″ file and hit “Start” button. That’s it. This should take around 5-10 minutes. If you get stuck right after hitting “Start” button, try another USB port and turn off Kies in Task Manager.

Step 7. When done successfully, you will see “PASS!” and your tablet will reboot.

If for some reason, you get “FAIL!” during the ODIN flashing process, simply reboot your tablet into ODIN download mode and try again. Also, if you see some type of “Firmware error” during boot, just try running ODIN in that mode, that’s same as ODIN download mode.

Step 8. Once rebooted, your tablet should be fully back to stock firmware.

Step 9. If for some reason, your tablet doesn’t boot up or you want to erase EVERYTHING on your internal storage and the phone for returning for warranty, you can do a factory reset using stock recovery.

Power off your phone (or pull battery) and hold down Volume Up, Center Home, and Power buttons together.

Step 10. Keep holding down Volume Up and Center Home buttons but let go of Power button.

Step 11. Once in stock recovery, choose “wipe data/factory reset”.

Step 12. Choose “delete all user data”. WARNING! This will ERASE EVERYTHING ON YOUR INTERNAL STORAGE!

Step 13. Once done, reboot system.

Step 14. Once rebooted, you should find your Galaxy S4 completely back to Day 1 you got the phone, congrats!

If you are not successful in flashing the 4.2.2 Turkish ROM, go back and flash the French 4.4.2 ROM.

You can download the French 4.4.2 ROM from here:

Repeat the above steps, but use the different ROM file.
