Not to be rude but this is not very useful, it's just a batch script with payloads in it. If I wanted to use a program with an option to load multiple different payloads I would just use TegraRCMSmash Gui, which is better than this batch script.
how do I install cosmocourtney's codehandler? I cant use anything in the main page of the trainer
I also have a file called codehandler.bin which i'm not sure what to do with.
