Phone problem i747m pls help

hello everyone , i'm new in this forum and i will appreciate any help from your part to help solve my problem
i have samsung galaxy s3 canadian version unlocked sgh-i747m , i'm using it in Algeria in my local network , i was using android 4.1.2 and everything were fine until i updated the firmware via kies to 4.3 everything work fine except some ussd codes like when i try to view my balance i dial *200# and i got the message " connection problem or wrong mmi code " i tried to put comma after # but doesn't solve the problem , i tried to downgrade to 4.1.2 but impossible as well ,
i found a way that may be the solution which is changing the CSC of the phone but all the application available need root access and i couldn't root the device via odin and autoroot file provided in the net it say pass at the end of the root process but supersu won't install and when i check with root checker it says the device is not rooted , i download root explorer but it's a bit complicated for me to use it , so any on how to root the phone or change the CSC without rooting , or downgrade back to 4.1.2 or or just solve the problem of the mmi code

First of all if you upgrade to 4.3 and try to revert back to 4.1.x you would probably brick your phone.
