Does using it require an unlocked bootloader, and will it unlock the bootloader in the process?

Trying to help my friend root so he can back everything up, then unlock his bootloader.

For T999, if its on 4.2.1 or prior version of Android, then the bootloader is unlocked. If its on 4.3, the bootloader is locked and there is absolutely no known way to unlock it.

And that would mean there's no way to root on 4.3 if my friend is already there, correct?

Hmmm.............. Well, not quiet. But the problem is, you may trip that dreaded warranty bit. Visit the Root66 Thread and flash that image UVUEMJC.

Would flashing the 4.3 from that thread lock the bootloader? I don't think it will, but just want to be safe.

Since the phone is already locked, that Rom won't re-lock it. It won't unlock either. That's why I recommended that Rom (UVUEMJC). If you tried prior Root66 roms, you will brick the phone.

His phone is on 4.1.2 so the bootloader should be unlocked. If he were to flash the Root66 4.3 would it lock the bootloader?

Do not flash the root66.. instead flash a custom recovery with Odin and then flash a stock rom and update modem if you're gonna flash 4.3.. that is the safest to do it if your friend cares about warranty.. you can still flash the root66 and it will be rooted but it may trip the warranty bit, I'm not too sure

I'm fairly sure his warranty is up unless it's lifetime, because he's had it for 2 years. Either way, I was just checking in case he decided to, I think he just wants to root 4.1.2 and stick with that for now.
