Hello forum, I apologize as this is an easy questions for you guys but I wanted to install Jellybean 4.2... on my sprint gs3. I originally rooted with the odin ??? and used it primarily for wifi tether. However, I keep getting these damn system updates from sprint and it goes into the bootloader and when it is flashing my device my andriod robot fall dead with his stomach hanging out with some checksum failure or something. I love the jellybean features and would like to install it. Sorry I am not computer wiz. May someone direct me how to install a rom and kernel??? I also can go into the bootloader.
