I have a Galaxy S4 Developers Edition (SCH-I545, running Android 4.2.2), Baseband version YUAMDK. I would like to install Kitkat on it. The problem is that I cant seem to find clear instrcutions on what I need to do to install a different ROM on it. Can some one please help. Also as a side question, where can I find the stock samsung kitkat ROM for our phone.
