Do these instructions still apply if I am S-OFF?

I have Htc one s4, HBOOT v1.13, and S-OFF. Do I still need to flash the boot.img separately or will it all get flashed in TWRP when I install a custom ROM?

You don't need to flash the boot IMG separately if you are s-off. It is flashed automatically from recovery when you flash a new ROM/kernel

Hi, just two things I wanted to mention/ask.
Maybe add as a note that the boot.img should be found inside the ROM.zip file. And, does this have to be done with every subsequent ROM flash? Or is it just once after the HTCdev unlock? Thanks!

Half bricked One S :(

Hi, I'll explain my particular case...

I had CM 10.1 working fine on my One S. To unlock it I should go back to the stock firmware ( T-Mobile ).

After many trys and fails my phono now it's on this stage:

.Keep looping on CyanogenMod loadscreen
.At least I can put it on fastboot mode.

my questions to the experts:
What should I do to install the Stock firmware from fastboot? :eek: ???

I have this RUU: RUU_Ville_U_TMOUS_1.84.531.2_R2_Radio_0.16.31501S.16_2_10.22.31501S.10L_release_263233_signed

it's correct for my phone? how to check this?

thanks in advice

Hey Guys,

since I heard many questions lately concerning flashing a boot.img onto the One S I decided to give you a small tutorial! (which should also work on any other device with bootloadermode)
If you have fastboot already installed on your PC it's very quick & easy!

Pls be aware that this could damage your phone & I'm not responsible for this. so only do this if you really feel comfortable with it & you know about the risks!


Here you go!
Quick & easy!

When I helped please press the thanks button!

If you have any suggestions to make it even easier of found a mistake, please tell me, it's already very late in Germany ;)

BE AWARE THAT I'M NOT RESPONSIBLE IF IT DOESN'T WORK OR BREAKS YOUR PHONE! THIS IS JUST THE WAY I UPDATE THE BOOT.IMG ON MY PHONE!

    Hey Guys,

    since I heard many questions lately concerning flashing a boot.img onto the One S I decided to give you a small tutorial! (which should also work on any other device with bootloadermode)
    If you have fastboot already installed on your PC it's very quick & easy!

    Pls be aware that this could damage your phone & I'm not responsible for this. so only do this if you really feel comfortable with it & you know about the risks!

    First of all you need to have fastboot & adb installed, as well as the drivers for the One S. If you haven't, move on to the second post in this thread!

    If you are on a Sense-based ROM make sure you haven't ticked the fast boot option in the settings!

    Step 0,5
    What is the boot.img?
    -> basically it contains the kernel & the ramdisk. But let's hear what the pros have to say:
    "The boot.img is a small(ish) file that contains 2 main parts, the kernel (the brain of the Android system) and the ramdisk (a core set of instructions and binaries that begins the boot process and controls base aspects of the system, such as mountpoints, memory management and startup services)" Source

    Do I need to flash the boot.img manually in fastboot?:

    • No, if you're using TWRP and are on a Hboot-version lower than 1.13
    • Yes, if you're using any other recovery (like CWM)
    • Yes, if you're using TWRP and your ville has the Hboot-version 1.13 or higher

    1.Step
    reboot your Phone into the bootloader.
    This can either be done via
    - powering off and keeping volume up & the power-button pressed
    - the extended power-menu (If your ROM has it, just select "reboot" & then "bootloader")
    - via adb, connect your phone with the pc, make sure it says "USB debugging connected", go to Android/platform-tools/ & then press shift while you perform a right click with the mouse, then choose "open prompt here", type
    Code: 
    adb reboot-bootloader
    & press enter. Your One S should then reboot into the bootloader

    I personally prefer one of the last two methods, depending which way occurs faster to me at that specific moment.
    Click to expand...
    Click to collapse

    2.Step
    make sure it says "Fastboot USB" like in the following picture
    loadera5adad4bJPG.jpg

    (Source = Google)
    Click to expand...
    Click to collapse

    3.Step
    Test if it your device has been detected with the following command:
    Code: 
    fastboot devices
    if it gives you an answer other than a blank one or an error there you go
    Click to expand...
    Click to collapse

    4.Step
    copy the boot.img you want to flash into the folder C:\android\platform-tools\ & then execute the command
    Code: 
    fastboot flash boot boot.img
    (if your boot.img is named differently then adjust the last part of the command)
    wait for it to succeed.
    if it says okay two times & the prompt reappears everything should be fine
    Click to expand...
    Click to collapse

    5.Step
    reboot your device with
    Code: 
    fastboot reboot
    Click to expand...
    Click to collapse

    6.Step
    If you want check
    Code: 
    Settings -> About phone -> Kernel
    if it matches the boot.img you just flashed
    Click to expand...
    Click to collapse

    The whole process should look something like this in your CMD:

    Here you go!
    Quick & easy!

    Installing ADB and Fastboot

    It's actually pretty easy!

    1. Step
    download the Android SDK from HERE

    Alternatively you can also download the USB drivers & the runtimes for adb & fastboot as a standalone as provided by Inferi0r in the 4th post:

    Click to expand...
    Click to collapse
    [Download carefully, didn't test them for viruses or (mal)function]
    Click to expand...
    Click to collapse

    2. Step
    Run the downloaded file & change the extracting-folder directly to C:\
    (..this will take some time...)
    You should then have a folder C:\Android
    Click to expand...
    Click to collapse

    3. Step
    If you haven't installed the One S' drivers yet, download HTC Sync (e.g. from here, or here) & install it, which will also install the drivers needed for adb & fastboot to work.
    If you have them installed already, skip this one & proceed to step 4.
    Click to expand...
    Click to collapse

    4. Step
    - go to C:\Android again
    - press
    Code: 
    Win + R
    on your keyboard to bring up the Run dialog
    - type in
    Code: 
    sysdm.cpl
    and hit OK
    - now, the System Properties panel should open. Click on the Advanced tab
    - in the Advanced Tab click on Environment Variables
    - at the Environment Variables window find where it says Path in the Section of System variables, click on it, and press the Edit button
    - when the new window opens, type in
    Code: 
    ;C:\Android
    at the very end and klick OK
    - now close all the windows, that's all, you're done!
    Click to expand...
    Click to collapse

    5. Step
    - go to C:\Android\platform-tools\ again
    - right-click with your mouse while pressing shift
    - select "open prompt here" & then you're ready to go to.
    - most common adb/fastboot commands:
    - adb commands
    - fastboot commands
    - by entering
    Code: 
    adb help
    or
    Code: 
    fastboot help
    Click to expand...
    Click to collapse
