I have been reading about surge method but not sure what it is. Does this enable boot loader unlock? I am on mk2.
Also if no boot loader unlock exusts. Is there a good touch wiz or fully stable aosp rom based off of kit kat? I could not find a tw one and not sure about aosp . None of the tw roms are being updated it serms
I have spoke of surge's upgrade/downgrade methods before. He is a senior member here on xda. The other method I know of, as far as upgrade/downgrade, is giglies. Giglies method came out after. It's fewer steps but the documentation could use an overhaul. If you see a post around the s4 forums with surge's name on it, I bet a lot of people are going to see what he has to say about it
