I found this link on cyanogen post for i9506.
And just a question. Can anybody help me on install pre-rooted rom 4.3 on my new i9506 ?
I understand that I must use ODIN and all is ok But what about CSC. I have Free telecom and my phone is unlocked SIM.
Which stable 4.3 version can I use ?
I am on 4.3 samsung Rom Version : JSS15J.I9506XXUBML6
This is a procedure. Does this procedure is safe for me :
Extract (unzip) the firmware file
I download this : Is it ok ?
Previous version 4.3 Stable release. - Kept if anything should go wrong...
GT-I9506 4.3 XXUBML6 - Stable, slim and Pre-rooted <--------- Download link. Updated 2014-03-17
I unzip : It's a tar.md5 file
Download Odin v3.09
Extract Odin zip-file
Open Odin v3.0
Reboot phone in Download Mode (press and hold Home + Power + Volume Down buttons)
Connect phone and wait until you get a blue sign in Odin
Add the firmware file to AP / PDA
