1. Use a card reader to format the micro SD card to exFAT (FAT32 or other formats does not work) in Windows. I haven't tried Linux or MacOS X, so they may not work.
2. Download the attached file (Root_for_ATTSG4_FM3.rar) and extract it into the root of your EXTERNAL microSD card using the card reader in Windows. (You can do the extraction using WinRAR or 7-zip).3. Put the SD card back to the phone and download the Android Terminal Emulator app. Via PC from Google Play . Or download direct via your phone (download from Google Play)
4.Open the Terminal Emulator app and run below.
5. commands: Code: cd /mnt/extSdCard ./pwn ./script.sh 4. Then, open SuperSU and check everything looks good.
6. Then open a root app and it should be working properly. 6. Reboot your device once to confirm root is still working after reboot.
.. Good Luck ..
