Galaxy S4 I9500 root problems.

Hello every one.
I have a problem with my Galaxy S4 I9500.
iv trued to root it already 5 times.
the odin is completing the process with secsess. but i still dont have a root. and cant install the SuperSU.
in the recovery i have an error.
please help. because i need to root the phone to install the custom rom. because my phone is randomly dropping the network. i think its software problem. becasue when im restarting the phone its working without a problem for aboute 15-20minutes and starting to decrease the network reception untill the no network sign appears!
Thank you!

What method are you using to root?

You are using one firmware branded:
- Device Name : Samsung Galaxy S4 Exynos Octa GT-I9500
- Device Model : GT-I9500
- Region Country : Israel (cellcom)
- Firmware Version : I9500XXUGNK1
- OS Name : KitKat
- OS Version : 4.4.2
- Date Update : 2014-11-21
- Region Code : CEL
But your CSC is ILO (unlock).
* COUNCIL: Download, unzip and flash via ODIN the latest firmware for your device: HERE. Try to root it then with CF-Auto-Root. This maybe solve the droping conection problems too :highfive:.

Hello. Thank you for youre recomendations. iv managed to install this rom!. but still have a connection problem, its dropping a network. i think there is a RIL problem. where can i find a RIL correct for my baseband. its I9500JKUGNH1
