Unlock HTC One X Bootloader

It was a great time last year, when HTC announced an official way for users to unlock bootloader of their Android phones. Although, not all the phones were supported, the famous and the latest ones did make it to the list of supported devices.

HTC launched a new site (htcdev.com) for that purpose. And it sounds like a developer only resource, which is true ─ it indeed is a developer only site, but the fact is that it’s used more by normal people than the developers. All thanks to the great community of pro users we’ve in the Android world.

Kudos! Android people.

Okay. Now lets get to the point of this post ─ Unlock HTC One X bootloader. And here we go..

Warning!

The methods and procedures discussed here are considered risky and you should not attempt anything if you don’t know exactly what you are doing. If any damage occurs to your device, we won’t be held liable.

Compatibility

This bootloader unlocking guide below may only be compatible with the HTC One X. Check your device model in Settings » About phone.

Pre-requisites [Important!]

  • Sufficiently charged battery, at least 50% is recommended
  • This procedure will wipe all your apps, data and settings (but it will NOT touch your SD card, so don’t worry about those). Backup your apps and important data — bookmarks, contacts, SMS, APNs (internet settings), etc. This Android backup guide would help you.

How To Unlock HTC One X Bootloader

STEP BY STEP INSTRUCTIONS

  1. Download the following two files:
    1. HTC Sync software → download link
      You’ll need it for installing proper drivers  for your phone
    2. Fastboot files → download link
      These are the files required to run fastboot commands on your Windows PC
  2. Now install the HTC Sync software you downloaded in Step 1.1 on your PC
  3. Extract the “fastboot.zip” file you downloaded in Step 1.2 on your PC and you’ll see the following four files inside a folder named “fastboot”:
    • adb.exe
    • AdbWinApi.dll
    • AdbWinUsbApi.dll
    • fastboot.exe
  4. Now open your Internet browser and go to this URL → http://www.htcdev.com and create a account for yourself using the Register link.
  5. After completing the registration and verifying your e-mail, login with your new account and open the “unlock bootloader” page.
    Here’s the direct link to the unlock bootloader page → link.
  6. Now select “All Other Supported Models” from the dropdown menu in the right and then click on the “Begin Unlock Bootloader” page.
  7. You’ll get a pop-up warning, read it if you care, and hit the “Yes” button.
  8. Now you’ll be asked to accept some legal terms, tick on both the check boxes and hit the “Proceed to Unlock Instructions” button
  9. You’ll see Four steps on the next page, below’s a more simple explanation to those steps:
    1. Switch OFF your phone.
    2. Press and hold “Volume down + Power button” together until your phone boots into bootloader mode.
    3. Select Fastboot using the Power button.
      You can use the Volume buttons to go up & down and Power button to select the highlighted option in the bootloader mode.
    4. Connect your phone to the PC with a USB Cable.
  10. Go to the second page on the htcdev site, click the “Proceed to Step 5″ button
  11. Now on the second page, you really don’t have to follow anything htcdev site is saying, instead, do this:
    1. Open the fastboot folder that you extracted in Step 3.
    2. Then open a Command prompt window inside the fastboot folder. To do that: “Shift + Right Click” on any empty white space inside the folder and select the ‘Open command window here’. See image below:
      Open Command Prompt Window Inside Fastboot Folder
    3. Now type the following in the command prompt window:
      fastboot devices
      This is to ensure that your device is detected, if nothing appears on screen with this command, then it means you don’t have the proper drivers installed on your PC. And if that’s the case you should download and install/re-install the HTC Sync software given in Step 1.1. And also restart your PC if required.
  12. That’s all you’ve to do on the second page. Now go to the third page on the htcdev site by clicking the “Proceed to Step 8” button at the bottom of the page.
  13. On the third page, follow all the Steps given on the htcdev site very carefully. And click on the “Submit” button when you’re done [You may watch the video given above for help]
  14. If you’ve followed the steps correctly, you will see a “Token Submitted Succesfully!” message on the next page. And also receive an e-mail with the unlock key attached as a file.
  15. Open the e-mail you received from HTC, and download the “Unlock_code.bin” file attached to it.
  16. Copy/transfer the “Unlock_code.bin” to the fastboot folder (extracted in Step 3) along with the other four fastboot files.
  17. Open the link given in the e-mail for further instructions.
  18. Flash the Unlock_code.bin file on your phone using fastboot:
    1. Type the following command in the command prompt window we opened in Step 11.2
      fastboot flash unlocktoken Unlock_code.bin
    2. Now on your phone you’ll receive an Unlock bootloader request. Use Volume Up button to select Yes and Power button to confirm and continue
    3. Your phone will reboot and will factory reset itself
  19. That’s all. Congratulations, your HTC One X’s Bootloader is now unlocked.
    To confirm, boot into bootloader mode (follow Step 9.1 & 9.2) and you’ll see “UNLOCKED” written with a pink highlight at the top of the screen

  • RonnPonce

    When I did this my phone now says ***TAMPERED*** ***UNLOCKED*** what does this mean? Running Rogers HTC One X software 1.94.631.6

    • http://www.theandroidsoul.com/ Kapil

      Um, did you try anything else too (any other way to unlock it), apart from the official way to unlock given above? That might be causing it. But anyway, you’re good to install cwm recovery, root your One X, and do more stuff. No problem with custom stuff.

      If for a reason, you take your One X to HTC service center, and the guy is knowledgeable enough to check bootloader status, he might deny you warranty. But that happens with official HTC unlock bootloader method too, with just Unlocked (no tampered thing here) written over there. So, it’s okay. Have fun with your unlocked HTC One X super phone.

      • RonnPonce

        The thing is now it won’t let me flash the Clockwork recovery so I cannot flash anything on my phone… when I flash the partition it only says

        “C:Android>fastboot flash recovery recovery.img
        sending ‘recovery’ (5452 KB)… OKAY
        writing ‘recovery’… OKAY”

        and it won’t let me boot into Clockwork. Do you have any ideas?

      • RonnPonce

        Yeah but the thing now is that it won’t let me flash the Clockwork recovery onto my phone. It only says,

        “C:Android>fastboot flash recovery recovery.img
        sending ‘recovery’ (5452 KB)… OKAY
        writing ‘recovery’… OKAY”

        And won’t let me boot into recovery. Do you have and ideas?
        I already tried “clearing the cache”. With no avail…
        Thanks

      • Ronn Ponce

        The one problem now is that my phone will not allow me to flash the Clockwork recovery. When I follow the instructions all it says it,

        “C:Android>fastboot flash recovery recovery.img
        sending ‘recovery’ (5452 KB)… OKAY
        writing ‘recovery’… OKAY”

        But it will not allow me boot into recovery. I already tried to “fastboot erase cache” with no luck. Do you have any ideas?

        Thanks

      • Ronn Ponce

        As well if I relock the bootloader will it erase all of my data?
