Alright, semi-noob question here. I'm not a developer or a hacker or anything, just a tech-savvy end user. I have a Tab 3 8.0 running Android 4.4.2 and I want to install a custom ROM. I'm familiar with Samsung devices on which you go into the developer options and select OEM unlock. I see no OEM unlock or anything of that sort in the developer options. Is the bootloader unlocked by default or am I missing something?
