adb-linux devices”.Īdb wait-for-device push firewater /data/local/tmp For Mac, use “./adb-mac devices” and for Linux/Ubuntu, use “sudo. You can type “adb devices” to check that your device is being recognized. If you get an error like I did that the device is offline, then go to your HTC phone and make sure you hit “OK” when “Allow USB debugging” window pops up. Open a command prompt for Windows and terminal for Mac or Linux. If you don’t see it, you don’t have HTC drivers installed, download and install HTC drivers. If using Windows, open up Device Manager and make sure you see either “My HTC” or “Android ADB Interface”.

If you are using Mac or Linux, you don’t need drivers, skip to Step 6. Copy the firewater file also into this folder like shown below:ĭownload firewater – Web Archive Download Here Also Unzip fastboot.zip and you should get a folder called “fastboot” in your Downloads directory. Next connect a micro-USB cable from your HTC phone to your computer. In this example, I am using CM11 ROM but you can use any custom ROM or stock ROM. Once you have a rooted HTC smartphone, you are ready to go. (You can refer to our How to Root Android! page)

To use Firewater, first you will need a rooted HTC smartphone. 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. 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. 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. 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. 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. This will work on most HTC smartphones with Qualcomm chip. For those of you who are interested in getting S-OFF your HTC smartphones, you can now use Firewater to do so.
