      Important notes: with 'Original USB cable' we mean the cable that comes with the phone made by Samsung. A 'FTDI USB cable' is a special unlock cable and is not the same as an original USB cable. If you have any questions about the different types of cables have a look at our Frequently Asked Questions page.

      If you don't have a (correct) cable here are some links where you can find most cables:
