Samsung Galaxy SIII (SGS3) has been shipped out to many countries either as International version or custom US variants coming through major cellular networks in USA including AT&T, Verizon, Sprint and T-Mobile. But among of those variants, Verizon Galaxy S3 that comes with an encrypted locked bootloader making even more hard to crack. That noy-unlockable bootloader will of course become a barrier for developers and tweakers to customize the SGS3 to its fullest potential. For your information, it is not one of Samsung’s habits as per Samsung’s track record, the company is always shipping devices with unlocked bootloaders. So in this case Verizon is the one to blame. Whatever the reasons are, there is always a way if there is a will.
Folks at XDA have always discovered a nice alternative ways to liberate many Android devices. And this time is coming from Elite Recognized Developer “AdamOutler” to come with a super-cool Linux-based tool named “Casual for Verizon GS3″.
The developer says that this tool is released thanks to leaked insecure bootlader by African-Canadian Sock Monkey. This unsecure bootloader is capable to skip signature checking on the boot partition of the phone. With this tool a user can root the Verizon SGS3 device, install hacking tools, flash CWM recovery, and much more with the final result is to install the insecure bootloader on it.
Before you proceed, make sure you do understand that once you’ve unlocked your SCH-I535, you should then avoid any new update from Samsung because it may possibly brick your device. Besides, Samsung or Verizon may break this method in the future by releasing Software Update.
