If you have any confusion over supported builds please read the HELP screen which you can get to from the Model Selection Screen.
To add support for 4.1.2 for your model/build please do the following:
NOTE: Stock boot images are needed to add support to the Toolkit. If you have rooted via custom recovery zip file the boot image will still be stock and fine to use but if you have rooted by flashing an insecure boot image please do not send anything as the file will be incorrect.
1. On the Model Selection screen enter any number for your model
2. In the Main Menu select option 5 and flash TWRP Recovery
3. Reboot to Recovery using the Reboot Device Options section
4. Select ‘Backup’ from the menu in TWRP Recovery
5. Untick everything except ‘Boot’ and swipe at the bottom to make a backup
6. Reboot the system back into Android
7. Copy the boot.emmc.win file from sdcard/TWRP/BACKUPS to your pc
8. Email the file to firstname.lastname@example.org with the full model/build number
Support will then be added and pushed as an update as soon as possible
For people who do not want or cannot get the Auto Update versions you can download twrp touch from http://goo.im/devs/mskip/recovery/samsung_galaxy_s3and flash it via the Toolkit. SuperSU can be updated to the latest version from the app.
[Auto Updates are only accessible if you have donated to the Toolkit project, received an activation code and unlocked the donator features. Auto Updates are a much faster and easier way of pushing small updates that would otherwise not be worth doing. I can push a single textual change or add support for a new build without having to go through the whole process of building a full version and uploading a large file. IF you are not able to or do not want to donate to unlock the Auto Update feature (and other donator features) then all the smaller updates are collated and a full build made when I have time or if there are enough updates to warrant it. This is the easiest way to make sure all the Toolkits are as up to date as possible. IF you have any views about this please pm me about them and do not post in the open thread]
