How to Get S-OFF HTC Smartphones using Firewater!

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.

Why S-OFF?

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”.

    I keep getting “-bash: ./adb-mac no such directory or file exists”
    Suggestions?
    Solutions?

    • Randall says:

      Fixed
      Had to change directory (cd) to where adb is located and everything seems to be running ok.
      Except firewater could not help achieve s-off for my device.

  2. Himanshu says:

    hey i want to convert my htc one m8 into google play edition.
    is it possible to flash GPE rom with S-ON?
    as i am unable to Gain S-off by both firewater as well as by sunshine method.

    Please help

    • Max Lee says:

      Yes ROMs don’t require S-OFF on HTC One M7 or M8. S-OFF is only required for flashing bootloaders and radios. You DO NOT need S-OFF to install custom ROMs at all.

      • Brian says:

        Hoi Max. If I flash a custom rom the phone{htc one m7} reboots in entering recovery and my twrp is v2.6.3.0
        If I download the latest twrp the white screen stays on with entering recovery.
        My question is will it help to s-off my phone

  3. Henry Ortiz says:

    Hello,
    I can’t get the S-OFF for my HTC One M7.
    it has the hboot 1.57 and the OS : 6.12.163.5.
    Perhaps Firewater can’t do it for the OS starting with 6. ?
    Best Regards

  36. Daniel Shaw says:

    I can’t seem to get past the same as /data/local/tmp/firewater when trying to execute the file. I got it to say that “permission was denied’ for a few times while trying to execute, haven’t been able to since.. I’ve followed the steps, but placed firewater into my platform-tools folder instead for easier access. Ran the push, shell, su, and execution but nothing happens.. I’m really trying to get Write-Read fixed on my HTC Desire 610 so I can at least fix the Mobile Hotspot problem from AT&T.. so any help would really be appreciated..
