Tutorial : How to unroot the HTC One in less than an hour

Tutorial : How to unroot the HTC One in less than an hourEarlier on, I’ve taught you how to root the HTC One in less than an hour. But for the benefits for those who may need to unroot their device to recover it’s warranty or stock ROM, I will move on to guide you on how to unroot the HTC One – which is slightly more challenging than rooting the device. Likewise before we begin, I would like to warn you that during the process of unrooting, there is a risk of bricking your own device. So if you still want to proceed, you’ll be doing it at your own risk and we will hold no responsible for any form of damage on your device. It’s also a good practice for you to backup your device before embarking on any of these procedures.

 

*This procedure works only if you’ve rooted the HTC One using this procedure. Similarly, it will only work on PCs running on Windows OS.

 

  1. Download the following files : Stock Firmware and Fastboot.
  2. Extract Fastboot to your desktop. You may need to download extracting software like bitzipper to your PC.
  3. Switch off the HTC One.
  4. Press the Volume Up and Power buttons simultaneously for a moment, to reboot the HTC One into bootloader mode.
  5. Connect your device to the PC using a USB cable.
  6. Open the Command Prompt on your PC.
  7. Type in the following commands into the Command Prompt :
    fastboot oem rebootRUU
    fastboot flash zip firmware.zip
  8. Reboot the HTC One..
  9. Congratulation you’ve successfully unrooted your HTC One!

 

That’s it! You’ve now brought your HTC One back to it’s stock firmware. If you need any help or experience any problem ( device hang, cannot boot? ) during the process, you can comment below this post.

      How to flash?
      (bootloader needs to be relocked)

      Re-lock your bootloader (this will most probably wipe content of your device)

      Copy downloaded .zip to fastboot.exe location (e.g. c:/SDK/platform-tools/fastboot.exe)

      Re-name .zip file to firmware.zip

      Open command prompt

      Boot your device in fastboot mode (vol down + power ===> fastboot)

      Connect device to the PC

      In command prompt cd to fastboot.exe location

      Make sure you have correct modeid and cidnum (type: fastboot getvar all)

      Type: fastboot oem lock (if your device is not relocked yet)

      Type: fastboot oem rebootRUU and wait for device to reboot

      Type: fastboot flash zip firmware.zip and wait for process to complete

      Sometimes flashing for the first time doesn’t work, so flash firmware.zip again just to make sure.

      Type: fastboot flash zip firmware.zip and wait for process to complete

      Type: fastboot reboot

      Unlock your bootloader and flash custom recovery if you are going to use custom ROM.
