NEED HELP Unlocking: Samsung Galaxy Exhibit SGH-T599V Cydia Impactor Rooting Error

Hey guys, like the title says, I am trying to root an old Samsung Galaxy Exhibit SGH-T599V smartphone (Error Install Failed Invalid Apk). I am using the Cydia Impactor to root. After enabling USB Debugging, I am getting the error:

file: adb.cpp; line: 525; what:
INSTALL_FAILED_INVALID_APK


I tried VRoot.app (King Root) but I need SuperSU to unlock the phone. Please help guys!
