My j327 is unlocked. I googled how to bypass the frp lock, I think is what's its called, but I entered bypass Google act lock. Then went to a video which used a file that said "combination" and followed the directions from the post. If i remember correctly, first you download the combination file, then download original firmware, with odin flash the combination file, then factory reset from inside your phone, flash the original firmware, hard reset again and your set. You have unlocked j3 emerge. I havent upgraded with the otg that the phone keeps asking, but it is unlocked. My memory isn't the best so Google what I mentioned. I wouldn't want you to follow my directions by memory since I only had to do this once, but I can confirm that the process works. Follow the guys directions exactly from his how to video. Hope this helps you.
