Exclamation [Q] HTC One Unroot 4.4.2???

Hello everyone. I want to get my HTC One Back to stock ROM and Stock Recovery with it Locked and Tamper thing gone. So I can receive OTA Updates again. I have a T-Mobile HTC One running KitKat 4.4.2. I currently have Team Win Recovery Project v2.6.3.0 installed.

OS4.19.531.10
EMMC-BOOT 2048MB

I am not 100% sure on how to do this because this would be my first time unrooting a device so I wanna make sure it is done correctly and I do not brick my device.

Any help would be appreciated.
