[Q] HTC One System Update rooted phone
I'm quite new to the android scene so please forgive me if this sounds an obvious question.
I have a HTC one that has been rooted and unlocked the bootloader. I haven't flashed a custom ROM to the device i'm still using the original factory OS. I wanted to flash a google edition ROM to my device but decided against it as I was a bit of a novice with Android.
Anyway I have a software update available to me on my phone which I can't install because it it rooted, could anybody help me with how I can install this update or how I can Unroot my phone and lock the bootloader again so I can install it.
