What is a bootloader?

The bootloader is the tool that loads the system software on the device and determines the priority for processes that will run your device.  In the simplest terms, this small program controls which applications must run in the startup (boot up) process.

Why did HTC have the bootloader locked?

Locking the bootloader has been a standard security practice in the mobile industry. Locking the bootloader protects you from malicious software and also allows manufacturers to ensure the device will consistently deliver the intended experience.

Why did HTC unlock the bootloader?

HTC was overwhelmed by the enthusiasm of our fans for the possibilities of developing software for HTC devices. HTC has a strong commitment to our developers and, in line with the launch of HTCdev.com and the OpenSense SDK, we felt it was important to fully enable developer success and unlock the bootloaders on our devices.

What does this mean for me?

Unlocking the bootloader means that you now have the ability to customize software on your device.  Please note that changing your bootloader can cause significant issues with your device and once you have unlocked your device, you have agreed to the disclaimer that states a change in warranty status such that in the event you render your device unusable, you are responsible for the recovery of your device, whether by repair or by other means.

Will all HTC devices be unlocked?

HTC is committed to assisting customers in unlocking bootloaders for HTC devices.  However, certain models may not be unlockable due to operator restrictions.  Please refer to our list of supported devices to see if your device is eligible for unlocking the bootloader.

Why do I have to log in multiple times when navigating throughout the site? Why does my request for the unlock code fail?

Our site requires a single IP authentication, and if you are behind a corporate network that may alter your IP address, certain features may not work as intended. We suggest you connect to our site via a direct connection, such as via a home network. We are sorry for any inconvenience and thank you for your patience.

Why doesn’t my token work?

Your token must be exactly the block of text that is highlighted in step 9. Do not copy the INFO or (bootloader) prefix, or the process will not register properly. 

If that does not work, it’s possible your phone is using an old software version that does not have the unlock mechanism built in. Try upgrading your phone to the latest update (On your phone HOME > Menu > Settings > About phone > Software updates > Check now) and then try the unlock process again.

Can I go through the process without having a device?

Currently you must have a device to unlock in order to run through the entire unlock process. You can still preview the process in the diagram here.

After unlocking the HTC One Max, I can’t access the fingerprint scanner?

Currently, for security reasons, you cannot access the fingerprint scanner while unlocked.

Why is my security still on (S-On) after I have unlocked my bootloader?

Your device is shipped with Security on (S-ON) to protect your system software configuration (such as the bootloader, radio, boot, recovery, system and others). After you have unlocked the bootloader, however, you will have lifted the restrictions on boot, recovery and system. This means you can customize boot, recovery and system images on your phone as you desire. You can easily see that you have successfully unlocked the bootloader by looking at the top of the screen when entering the bootloader screen. Security is left on to protect things like the radio, and SIM lock.
