Guys ... if kies is not working for you, and youve done all the proper things like: downloading the correct version of kies for your model (not necessarily the current one) making sure you have the correct samsung usb drivers and most importantly double checking your carriers model number (carriers use the same model number but add an extra letter number or two, to teflect their company) , then its time to learn how to use odin. This is an old thread, and only pertains to the mentioned phone per say. Tbh im starting to think that Sammy has legacy'd the older galaxy and have excluded them from kies all together. If it doesnt work, dont tske any chances on borking your phone its time to learn how to use Odin. The same of course applies: carrier/model specific for flashing. I have not used kies in years because imo Odin is now the way to go, but info up before you do anything. Im on a gn4 atm and once i get my hands on the new puxel xl or maybe a gn8 (if that happens) ill test out kies and see what works and what doesnt with my phone. If any one has used kies recently please post your model and experience.
