    Thank you for the clear instructions to unlock the One V. :-)
    Before I complete the root process, I was wondering how you return the phone to the original settings.

    Is there an app I should use to save the “image” and restore it if I choose to unroot?

    Noob from Canada LOL

  • Arman

    I do this all what u said. And it worked. But after restart my phone and open Titanium Backup it says “root access: Failed”. So I can’t see the rom or edit it. Please help me. How can I fix this on my One V?

    • Arman

      I have the latest HTC sync software. I tried it 3 times. But still in that position. Please solve it for me.

    • Viraj SK

      You have to root your phone. Just unlocking bootloader doesn’t root the phone…

  • Sumit

    I have installed the latest version of HTC sync doftware on my Win 8 Pro,
    and in device manager, It says that the Driver is up-to-date
    but still I am not getting anything when I type fastboot devices at the command prompt.

    please suggest?

    • Shubhangi

      Hi, I’am also getting the same problem with my device. I tried uninstalling and re-installing the HTC sync software too (I’m using Windows 7). Tried everything after a performing a restart but nothing happens. It just gets stuck on waiting for device when i try to enter the command given on the HTCdev site i.e. ‘ fastboot oem get_identifier_token ‘. Please help me with this. Please _/_
      I would be very grateful to you.
      I really really want to root my device.

  • Shubham Kishore

    Thank you for the instructions Viraj, it really worked!!!!
    But I guess I have another problem now. I unlocked my One V using the same instructions given above, It got unlocked too but the I cannot restart it in Bootloader mode now.

    • Viraj SK

      1) Enable USB Debugging in your phone
      2) Connect your phone to PC and using the same procedure above
      3) Now open command prompt and type the following command,

      adb reboot bootloader

      Tell me if it works or not..

      • Shubham Kishore

        Viraj,the issue here is, to follow those same instructions I need to get into bootloader mode, which at present I can’t get access into.
        Any other alternative?

        • Viraj SK

          No need to boot into bootloader. You have to perform this step normally.
          Connect your phone when it is switched on (just remember to enable USB debugging)…

        • Marmik Patel

          Did as you mentioned but the cmd says
          adb server is out of date. killing…
