For those of you who are interested in getting S-OFF your HTC smartphones, you can now use Firewater to do so.
This will work on most HTC smartphones with Qualcomm chip. I was able to use this method to get S-OFF on bunch of my HTC phones including AT&T One X (One XL), HTC Evo 4G LTE, and HTC One M7/M8.
S-OFF on older devices like AT&T One X allows user to flash custom ROMs normally without having to use a computer to flash kernel (boot image) via fastboot.
On newer HTC devices like HTC One M7 or M8, you do NOT NEED S-OFF as custom ROMs will install normally but by having S-OFF, you will be able to install bootloaders/radios. This can be useful in cases where you need to upgrade the bootloader on newer Android OS versions so you don’t have to unroot your phone back to stock firmware.
I usually do NOT promote S-OFF especially on newer HTC phones as they are dangerous but I found that Firewater method is very safe to do and does not cause hard bricks like I have seen with other S-OFF methods.
To use Firewater, first you will need a rooted HTC smartphone. (You can refer to our How to Root Android! page)
Once you have a rooted HTC smartphone, you are ready to go. In this example, I am using CM11 ROM but you can use any custom ROM or stock ROM.
Step 1. Enable developer options on your phone by going to Settings->About phone and hitting the “Build Number” about 5 times until it says, “You have enabled development settings”.
Step 2. Hit the back button once and you shall see a new Settings menu called “Developer options”. Go into it and enable “Android debugging” or “Android ADB Debugging”.
