you don't, its locked, you cant instal custom roms.
sorry pall

Contact with T-mobile to unlock the bootloader. You might have to pay for it.
If you can't, you only have the options for locked bootloader ROMs. CWM is there as well with many mods
Hit THANKS if I helped.

[Q] How to relock bootloader

Can someone guide me how to relock the bootloader on UHD 2.03 rom. And one more small question, should I revert back to stock kernel to relock the bootloader or is it okay to stay on Advanced Stock Kernel.
I could not find any thread talking about this for the Arc. So if you know any threads, kindly post me the link

Let us know which worked for you.

I asked this second question " if it requires the stock kernel to rlock the bootloader" . So the second link on google said I need to revert to stock kernel, but iam not willing to sacrifice the great battery from Advnced Stock Kernel and relock it. I decided to let go, but thank you for helping
