Some months ago I flashed hyperdrive on my brother's s4 and it appeared to have somehow flashed over the stock 4.3 ROM and now has Wi-Fi issues. Anyways, I'd like to get the stock system back without really messing something up.
Additional info: the phone is mk2, bootloader locked and the hyperdrive version is RLS 13.
I don't know much about the s4, so, sorry if I ask any nooby questions.
