Let’s head to the next page where we have mentioned the detailed guide on how to achieve S-Off in your HTC One smartphone.

Procedure to Achieve S-Off in your HTC One Smartphone:

  • Connect your HTC One with the computer using the original USB cable. Download Revone in your computer and push the same to your device with the help of below command;

adb push revone /data/local/tmp/

  • Now open the ADB Shell and enter the below mentioned command,

cd /data/local/tmp
chmod 755 revone

  • Just in case if you device is unlocked and rooted you need to switch to root using the su command. Prepare to gain the S-Off by entering the command as

./revone –P

  • Just in case if revone reports success, then reboot the device to the next step. If revone reboots the device (we’ll pretend this isn’t an undiagnosed random crash) please wait 2 minutes then try again from step 2 of “cd /data/local/tmp”. If revone reports that you need to reboot and try again please reboot and try again from step 2. Once the device is successfully prepared for S-Off, open other ADB Shell and change to /data/local/tmp directory. Now, all you need to do is to instruct to Revone about the unlock Status by running the status of

./revone -s 0 –u

  • In the meanwhile, you can also make use of the  below mentioned commands for your use;

* -u – Unlock the device
* -l – Lock the device (as if it was never unlocked)
* -r – Relock the device (mark the device as relocked)
* -t – Reset the device’s tamper flag.

  • Assuming that Revone has been successful, you need to enter the command as “adb reboot bootloader”. Now, re run the Revone to remove the TAMPERED from your HBoot Screen by entering the command;

./revone –t

Tip: Just in case if the device refuses to turn ON, you will need to long press the power button and then re apply the firmware update again.
