CF-Root is not working on your Samsung Galaxy S III? No worry, XDA Developer, Chainfire has another way for you to root Samsung Galaxy S3 ~ CF-Auto-Root. CF-Auto-Root supports Samsung Galaxy S3 GT-I9300, GT-I9300T, GT-I9305, GT-I9305T, GT-I9305N, SHV-E210K, SHV-E210L, SHV-E210S and SHW-M440S models. Unlike CF-Root, CF-Auto-Root provides root access with SuperSU binary and SuperSU application only. So no custom ClockworkMod (CWM) Recovery and CWM Manager application are installed. Good for those who need root access only…

How to know which Samsung Galaxy S3 model that I have? Go to Settings – About device – Model number. You should see Model number as GT-I9300 like picture above. Make sure that you download and install the correct CF-Auto-Root for your SGS3 model. And be sure to get more information at XDA website.

Dear Jayce
Please be good enough to explain the compatibility of OTA and updating via Kies with this rooting technique…
Personally, I did not try CF-Auto-Root on my SGS3. No idea about OTA. But Samsung Kies should working fine with it just like CF-Root.
Thanks pal, I really appreciate your quick response…
ota will not work because of modification
Dear Jayce,
Is there a way to root my S3 without using a usb cable?
Try Mobile ODIN Pro.
Already tried it, but asks for super user access…
My mistake, forgot about that you need root access first in order to use it. I have no idea then.
Dear Jayce,
Please be good enough to get me the English version of cube i6 air 3G dual boot tablet android rom. I had to factory reset it coz it gave me some trouble and now it shows in Chinese only.
Thank you very much.
