How to Unlock HTC One M9 Bootloader

Now that One A9 root is available, you will be looking at the means to unlock bootloader of the device first.

Know that the procedure is done using HTC’s own website for the purpose. So, if HTC says your device is not compatible or eligible for unlock, there is nothing that can be done. You will get to know that in step 12 below.

Unless your One A9 is from Verizon or Sprint in USA, it should be easily unlockable, or eligible from HTC.

Unlocking the bootloader of One A9 is your first step into the world of little device hacking which starts with installing TWRP recovery next, and then achieving root access, followed by root requiring apps, or even better, Xposed framework and modules.

Well, here is our guide on how to unlock One A9 bootloader, right here for you.

Info:

Unlocking bootloader of any device involves a certain degree of risk. You must note and understand the following before proceeding with bootloader unlocking process:

Unlocking the bootloader will void the warranty of your phone permanently and you’ll be unable to get any support under warranty from HTC.
All the data on your phone will be wiped, including personal content on the internal storage such as photos, music, videos and other files. You can take a backup of everything though and restore it later on.
While you’ll be able to obtain official software updates from HTC after unlocking bootloader, there are chances that it might cause issues so it’s best to not accept official software updates.

Warning!

Warranty may be void of your device if you follow the procedures given on this page. You only are responsible for your device. We won’t be liable if any damage occurs to your device and/or its components.

Backup!

Backup your Android. Backup important files stored on your device before proceeding with the steps below, so that in case something goes wrong you’ll have backup of all your important files.

Before you begin with guide instructions below, make sure your android device is adequately charged — at least 50% battery of the device.

How to unlock One A9 bootloader

Install HTC One A9 driver. First step to hacking your device begins with installing drivers, doesn’t it?

Now, install ADB and fastboot driver. This makes sure that your device recognizes fastboot command and get you token in step below.

Let’s begin now. First of all you need to register and create an account on the HTC Dev site: Here.

After completing the registration, you will need to verify your e-mail address. Go to gmail, yahoo, hotmail or wherever your email ID is, log in, and then look for a mail from htcdev.com. Open the mail, and verify by clicking on the verification link.

→ If you don’t see any mail from HTC Dev within 30 mins from registering, then also check your Spam folder.

Go to the following link and login with your account: here. Now, click on Unlock bootloader and click Get started to finally begin with unlocking.

On PC, either create a new folder and name it as onea9unlock and open that folder. We will open command window into this folder in next step.

Now, open command window in the chosen folder. For this:

Left click on empty white space in the folder.
Now, while holding shift key, right click on empty white space to get a pop-up as shown below.
Now choose Open command window here option from that.

You will see a command window open up, with location directed to onea9unlock folder.

Boot into download mode. Run the following command in the command window for that.

adb reboot download

Connect your HTC device to PC now.

Now, get the identifier token of your One A9. For this, on PC, in command window, run the following command. (You can copy paste it too.) After entering text, use enter key to run it.

fastboot oem get_identifier_token

You will see a long text of token. You have to copy it now. For this:

First, right click on an empty space inside command window, and select Mark.
Now, highlight the block of text starting from <<<< Identifier Token Start >>>> and ending with <<<<< Identifier Token End >>>>>.
Right click on the highlighted text to copy it. (Refer to the image below.) Press escape key to get rid of pop-up from last right click.
└ It may say <info> instead of <bootloader> but don’t worry, the procedure is the same.

Now, provide this token to HTC, so that they send you the unlock code for your One A9 to your email ID with which you registered. Do this.

Go to the following link here.
Scroll down to the bottom where it says My Device Identifier Token and paste the previously copied token here. And then click on Submit.
└ Copy and paste the token directly from Command Prompt window to the web page. DO NOT try coping it somewhere else first (Example: Notepad) and then pasting from there to web page.

If you did it alright, HTC will receive your token code, and will send you an e-mail with your Unlock_code.bin attached to the e-mail.

Download the Unlock_code.bin and transfer it the folder you chose above, where you have the command window pointing location to.

Close the command prompt window and open it again in that folder as above (step 6). And then run the following command.

fastboot flash unlocktoken Unlock_code.bin

Look at the phone now. A screen will appear on your phone now asking you to confirm the Bootloader unlock. Use Volume Up button to highlight Yes and select it using Power button.

Your HTC One A9 will now reboot and the bootloader will be unlocked to fulfill all your flashing and modding needs. You can disconnect your device from computer once it fully boots up.

Verify Bootloader Unlock

To confirm if your bootloader is unlocked boot into Bootloader Mode (Step 4), it should say *** UNLOCKED *** at the top of the screen.

Enjoy!

That didn’t work. First, you don’t tell us what screen or mode to put it phone in during the process. Second, what mode our screen should we be in when we use adb to put the phone into download mode? Shouldn’t you also tell us to make sure we have activated developer mode? And click allow boot loader unlock? Despite all that, without specific committed steps your process didn’t do anything but confuse everyone!
