Unlock Htc Droid Dna Bootloader [How

The Droid DNA is a monster of a phone that successfully raises the bar for manufacturers looking to release a new flagship device. When it comes to sheer horsepower, the mighty Android from HTC simply blows away a lot of competition – all the way from its mind blowing high-res screen, to the CPU that it employs, to the sensors and ergonomics that it carries.

The smartphone speaks class, and it was impossible that it won’t have piqued the interest of all the developers out there. Owing to that fact, the phone got root and custom recovery et al, all before the device was actually available. We even brought you a guide on how to gain root on HTC Droid DNA, but that’s not the point right now. As it turns out, the device’s bootloader, which is essential to all the modding that you want to apply, cannot be unlocked now through HTC’s official tool.


The whole concept and set of instructions provided are credited to Justin Case, and Android Police, where the guide was initially published, and whose exclusive property it remains. With due credit to them, we lay down these instructions and related requirements for the benefit of our readers.

You should also remember that this process involves some serious modifications to your phone – ones that can render the device absolutely bricked (with no hope of recovery) if not followed to the letter. Do read through the whole guide first before doing anything. We will not take any responsibility if something goes wrong. You have been warned!



Windows/Linux PC with ABD for ICS or above configured.

Minimum 1GB of free space in your Droid DNA’s internal memory.

At least 50% charge on your phone’s battery (full is recommended).

Patience and ability to follow instructions as they are given.

You can grab all the needed files from the source link at the footer of this post.


Step 1: Download both the files mentioned above. Extract the contents of, and place the chúng tôi , CIDGen.apk and chúng tôi files in the same directory where you have ADB installed.

Step 2: Launch a command prompt or terminal instance, and run the following command:

adb install CIDGen.apk

Step 3: Launch CIDGen on your phone, follow the instructions on screen, and verify the existence of chúng tôi in the root of your Droid DNA’s SD card/internal memory using this command:

adb shell ls -l /sdcard/CIDBLOCK.img

Step 4: Proceed only if chúng tôi exists; otherwise, just run the app again and try verification once more. Once the file has been verified, run these in terminal or CMD:

adb push chúng tôi /data/local/tmp/ adb shell chmod 755 /data/local/tmp/ adb shell /data/local/tmp/

Step 5: Open a second terminal or command prompt instance, and restore the modified backup using the command below. Do note that the first window will enter into an infinite loop, and throw various error messages. Just leave them as they are for now, do not get alarmed.

adb restore backup.ab

Step 6: Allow the modified backup to restore on your phone. Once that is complete, stop the first command prompt by simply closing the window (this will kill the chúng tôi script).

Step 7: In the second command prompt window that you had opened, run the following set of commands. Justin warns that any interruption at this point – reboot, disconnection from PC, power off et al – will permanently brick your device.

adb shell rm /data/data/* adb shell mv /data/DxDrm /data/DxDrm_org adb shell mkdir /data/DxDrm adb shell ln -s /dev/block/mmcblk0p5 /data/DxDrm/DxSecureDB adb reboot adb wait-for-device

Step 8: At this point, you’ll need to run the chúng tôi script again. Command is same as before, and will put it in an endless loop as well:

adb shell /data/local/tmp/

Step 9: Again, launch another command prompt/terminal window, and restore the modified backup once again, just like we did in step 5:

adb restore backup.ab

Step 10: Once it’s restored again, terminate the chúng tôi exploit by closing the previous window, and run these commands:

adb shell mv /data/DxDrm /data/DxDrm_trash adb shell dd if=/sdcard/CIDBLOCK.img of=/dev/block/mmcblk0p5 adb reboot

There you have it. After this reboot, you have essentially changed your Droid DNA’s carrier information, and it can once again be unlocked through

Unlock Bootloader Tutorial For Verizon Htc Droid Dna

HTC Droid DNA Unlock Bootloader should be the first guide that all power-users need to read before installing any applications or adding files to your smartphone.

The HTC Droid DNA can easily have its bootloader unlocked, and you can learn how to do it by reading this post. After you’ll unblock the bootloader you will be able to install new custom ROMs, kernels, modification files and any other things that will allow you to customize your Droid DNA phone in any way you wish. Read the entire post and only when you’re sure that you know what you’re doing, move to the tutorial guide.

Usually, Verizon doesn’t like their device to be on unlocked bootloaders but it seems like the HTC Droid DNA can be unlocked from HTCdev and you should do it before any security patches will be released to fix it. Now that you know all this general info, move to the pre-requisites guide and learn what tools you need and what you need to do before starting to unlock the bootloader of your phone.

Use the info below to correctly configure your PC and your HTC Droid DNA so that you’ll unlock its bootloader from your first attempt:

This guide will void your warranty. Not future update will be available for your device and the only method you can use to upgrade your device will be by using manual tutorial and applications.

Use this guide only with the Verizon HTC Droid DNA smartphone. Do not attempt to flash the files listed here on any other device.

Install the HTC Sync Manager software on your computer from HERE.

Note that this guide will remove all data from your smartphone and it would be better if you’d apply the steps before you install any applications, transfer files etc.

You will need a working internet connection as you will have to connect to HTCdev’s website.

Enable USB Debuging option from the phone’s Developer Settings.

Charge the phone’s battery so that you won’t see it discharging before applying the changes I’ve listed in the tutorial.

How to unlock HTC Droid DNA Bootloader:

Download the Fastboot zip file from HERE. Extract the files contained within it and save them to a single folder named ‘fastboot’, on your PC desktop. You will have 4 files in this particular folder. NOTE: The HTC Sync Manager Software should be installed on your computer before moving to the next step; the download link for it can be found in the pre-requisites guide above.

Follow the on-screen instructions shown on the HTCdev web page. These should say ‘Power off your device’, boot your phone into bootloader mode by pressing simultaneously ‘volume down’ and ‘power’ buttons. Choose ‘Fastboot’ and then connect your HTC Droid DNA to your computer via USB Cable.

Go to the ‘Fastboot’ folder that you created at step 1, open it.

fastboot devices – This will show the HTC Droid DNA device ID. IN case this doesn’t appear then you will have to re-install the HTC Sync Software files, which can be found in the preparation guide.

Open that e-mail message and download the file called ‘Unlock_code.bin’ attached file. Save the file in the ‘fastboot’ folder; the one created at step 1.

Now you will have to open the link that is listed in the e-mail.

Use Fastboot and the Command Prompt window to flash ‘Unlock_code.bin’ file to your phone:

fastboot flash unlocktoken Unlock_code.bin – enter this command line.

the HTC Droid DNA will get a request for ‘Unlock bootloader’ and you have to press the ‘Volume Up’ and Power to confirm this action.

Now your smartphone will restart and a ‘factory reset’ process has been started. When that’s complete, your phone will boot normally and it will have its bootloader state set to UNLOCK. That’s it!

These were all the steps that you had to take and now you’re free to root your phone and install custom recovery, custom ROMs and any other modification file that you think that will improve the performance of your phone.

If you want to check that your HTC Droid DNA Verizon has the bootloader unlocked, then you should use the steps below:

Power off the phone.

Boot into Bootloader mode using the ‘Volume down’ and ‘Power’ buttons at the same time.

You should notice that the ‘UNLOCKED’ text is shown on your phone’s screen.

UPDATE: The guys at XDA are saying that the bootrom is no longer unlockable, and this means that this guide will not work with your Droid DNA phablet. Knowing the XDA developing community, we should get a new bootloader unlocking guide in not time, which is why you should keep an eye on our website .
