If your software returns a connection error, verify that you are not using standard recovery mode. Test the integrity of your USB port using a short, high-speed data sync cable rather than a generic charging wire. If the loader fails at the "Sahara initialization" phase, it means the binary security level of your device is higher than what your firehose file supports. In this scenario, source an updated programmer file that explicitly accommodates your current Samsung security patch version.
