@kevinfuerst,
i believe they are looking for a way to s-off, unlock, root, install custom recovery, and install cyanogen all in one thread. i have not seen anything of this sort but also have not looked for one either.
i just installed cyanogen today on my verizon HTC one after successfully getting unlocked, s-off and root using rumrunner s-off tool.
@yacoubean,
if you are wanting to install cyanogen mod then there are several things you have to do to get it on the phone. i have not read the guide you linked but here is the basic gist.
As for the HTC drivers just follow the rumrunner s-off tool's instructions. it will tell you what you need installed and what you need to disable/enable for the tool to work.
1) unlock bootloader, get s-off. you have to do this before you can install any type of custom rom. there has just been an s-off tool released recently called rumrunner. you have to make sure you use the rumrunner version for the version of your phone. (i.e. have you installed the recent over the air update on your phone from verizon?, if so then you need to make sure you use the rumrunner for that version of your software)(lets also not get into an conversation that you don't need s-off technically to install recovery/rom. s-off makes it much more convenient).
2)install custom recovery. TWRP and CWM are 2 that work on the verizon HTC one (please make sure you install the verizon version and not another carriers version).
3) download your rom and install via your custom recovery. instructions on how to install the rom are found on the forum thread for the rom. you will most likely have to clear cache and dalvik cache to install any custom rom, which effectivly wipes out data on your phone (txt msgs, apps, etc..) again read instructions on the forum for the rom.
s-off is a safety feature on HTC phones. basically it gives you full control of the phone and partitions. if you are not s-off then there are certain things you cannot do (like install different radios), or if you can install certain things then the changes get wiped out with a phone reboot. I highly suggest you read and understand what s-off is. if you are s-on then the phone will not allow you to install unsigned packages. basically any packages that didn't come from verizon or htc. if you are s-off then you can install anything you want, including items that will brick your phone if you are not careful. this means you don't install sprint/t-mobile/att kernals, roms, etc... on your phone. only install things that say they are specifically for the verizon HTC one!!!!
