[Q] Is it necessary to unlock the bootloader before installing a custom ROM?

[nashton]

Good morning/afternoon everyone,

I have the lovely new Tab Pro 8.4 and would like to update to CM11. However, I cannot unlock the bootloader (multiple computers have been tried, in Odin mode, adb devices sees the unit, but fastboot does not. I did get a TWRP recovering installed).

Is it necessary to unlock the bootloader before installing CM11?

Many thanks in advance for any answers. I have looked around a great deal, and it isn't clear to me from the many overlapping set of instructions if this is really necessary or not.

No need to unlock. Just flash or odin.

No, you can just flash. No need to unlock bootloader, because you set the knox bit by flashing recovery by odin.

Setting knox (by flashing) "may" void your warranty. But in many cases users got repairs by warranty service, even if the device is rooted. My HTC ONE X also rooted has been repaired by warranty service for free. They told me, that my device was rooted, but the issue was hardware failure.
