Windows 32/64 Users: CASUAL will put your device into Download Mode. It will automatically flash everything. If drivers are required, jrloper's CADI (CASUAL Automated Driver installer) will handle it. Make sure you're connected to the internet.
Windows 8 is supported but you must install drivers for Download Mode first. See this post
We managed to squeeze in support for Windows XP. Let me know how it works XP users.
Linux 32/64/raspberry pi Users There may be a permission escalation in order to install heimdall, either way sit back and relax. CASUAL automates the entire process. Please run the following in a terminal first:
sudo apt-get install openjdk-7-jdk gksu dpkg
Root and Recovery for ATT-TMO GS4-CASUAL-R527b CASUAL is used to automate the process. The exploit was developed by Recognized Developer djrbliss. Any donations should go to him. I'm just here for error logs. To run CASUAL you need Java. Do you have Java?

Help and Troubleshooting
Are you having a problem? First check this post out for remedial troubleshooting. . If that doesn't fix it, then press CTRL+L, press the Pastebin button, come back here and press CTRL+V to paste your log. Don't hit the donate button, that doesn't fix it. Use CTRL+L and then hit Pastebin and paste the log here if you need help. Most problems simply require you to reboot your device or computer or removing and "delete driver" any drivers you installed. If you installed drivers to start with, remove them (and delete driver from device manager), because this device is fully supported natively by Windows and 3rd party drivers cause problems.
CASUAL stands for Cross-platform Android Scripting, Univeral Auxiliary Loader. CASUAL jar files are a wrapper for the CASUAL scripting language. CASUAL can be modified with your favorite zip tool and full source code (including this exploit) is available at http://android-casual.googlecode.com . CASUAL allows rapid and accurate deployment of hacks and exploits. At any time, if a serious problem is detected with any script, the kill-switch will be flipped and you will be brought to a support page (most likely here) so you can download the latest version. Otherwise for minor corrections, new CASUAL scripts can be deployed remotely.
