With great power comes great responsibility -- S Off is a reality for the HTC One, Droid DNA, and J Butterfly
The methods (yes, there are two of them) are pretty straightforward, using either a Linux-only utility or by manually running a few commands via ADB or right from the phone itself. Be warned -- having S Off makes it easier to seriously break your phone, so make sure you have a reason to do it before you get started.
Speaking of a reason to do it, many folks wonder just why you need S Off now that HTC let's us all flash boot images with an unlocked bootloader. There's one big reason -- SuperCID. CID stands for Carrier ID, and it's the determining factor of which RUU you can run to update your phone software. With SuperCID (as seen above -- 11111111) you can flash any RUU to your phone, including the developer edition and upcoming Google edition versions, providing there is support for the radio. This means when the unlocked world version gets updated to 4.2.2 and the RUU is "uncovered", folks with S Off won't have to wait for AT&T or Three to approve the update and push it out. There is also some speculation that this may allow the AWS bands on the developer edition to get unlocked for use on T-Mobile's 3G. Never say never.
In any case, if you're aware of the risks, understand what you can do afterwards and know what you shouldn't do at all, hit the links below to get started.
