+TK1 Loader (tk1-loader.sh)
+
+A versatile payload injector designed for the NVIDIA Tegra K1 (T124) and similar platforms.
+This script acts as a front-end "driver" for various RCM (Recovery Mode) exploitation and loading tools,
+removing the need to remember complex command-line arguments or hex addresses.

+
+Overview
+The script automates the process of finding your compiled U-Boot or SPL binaries and pushing them to your device
+using one of several supported backends. It saves your preferences in a local .tk1_loader_config file so you only have to
+configure your tool paths once.
+
+
+Setup & Usage
+
+1. Initial ConfigurationBefore the first run, you must define which tool you are using and where it is located:
+  you mught have to chmod this as well : chmod +x tk1-loader.sh
+  ./tk1-loader.sh setup
+During setup, you will:
+Select a backend (shofel2_T124, fusee_glee, tegrarcm, or Custom).
+Provide the path to the executable.Optionally set a Default Payload (e.g., u-boot-dtb-tegra.bin) for auto loading.
+
+2. Pushing a Payload
+Once configured, simply run the script without arguments:
+  ./tk1-loader.sh
+If a default is set: It will immediately attempt to push that file.
+If no default is set: It will recursively scan the current directory and all subfolders (like spl/) for any .bin
+files and present a numbered menu for you to choose from.🛠
