So I have the AT&T S5 with a locked bootloader. I rooted it, put safestrap on it, and installed a custom ROM. Now I read that the Tmobile S5 has an unlocked bootloader, but given that I can root and install custom ROMs, why is the Tmobile variant any better? Also I read locked and encrypted used interchangeably regarding the bootloader, perhaps they are both locked but not encrypted?

Lastly, does an unlocked Tmobile S5 work seamlessly on the AT&T network, it appears the LTE bands overlap so I'm guessing so. Is there a good reason to sell the AT&T variant and get the Tmobile one?

Ungh, stupid AT&T.

You can only flash custom roms based on the stock kernel. With a locked bootloader you'll never be able to flash an aosp rom.

Nor will we be able to flash 4.4.4(or later) when it becomes available. We are stuck waiting for att to release an update, and then we might lose root.

Does this mean that the custom roms that are installed are still ultimately based on the original G900A one, or at least the kernel is the same?

Basically, yes.

The recent OTA will update the kernel and firmware, right? But does towelroot still work? Is it likely that the bootloader will be more difficult to break later if I do update?
