On July 11, we reported that HTC is in the process of releasing ‘unlocker bootloader’ for HTC Sensation Android Smartphone. The company has now begin the process of unlocking bootloader for the HTC Sensation (EU) FOTA 1.45.301.2 device, though it shows that both the HTC EVO 3D (Sprint) and the HTC Sensation 4G (T-Mobile USA) handsets will be unlockable soon.
Unlocking the bootloader allows users to customize software on their devices. It was only in May this year that HTC CEO Peter Chou announced via their Facebook page that all of the company’s future devices would be open, saying “There has been overwhelmingly customer feedback that people want access to open bootloaders on HTC phones. I want you to know that we've listened. Today, I'm confirming we will no longer be locking the bootloaders on our devices. Thanks for your passion, support and patience.”
HTC also made it crystal clear that if you choose to unlock your bootloader, “not all claims resulting or caused by or from the unlocking of the bootloader may be covered under warranty.” And, also that unlocking your bootloader does not mean that you will be able to unlock the SIM lock. Unlocking your SIM lock is at the discretion of your operator/carrier and is not part of the bootloader unlocking scope.
Per HTC’s blog post:
Our devices have been designed with our hardware and software specifications in mind and unlocking the bootloader will change the software and may cause unexpected side effects. It is impossible for HTC to ensure the proper functioning of your device after this. In the worst case scenario, it is possible that your device may be physically damaged due to overheating or the behavior of your device might be altered including, but not limited to, hearing aid compatibility (HAC) and specific absorption rate (SAR) values.
Some content on your device may also be invalidated and cannot be accessed any more because of invalid DRM security keys. This includes content that you may have purchased through a 3rd party vendor and through HTC. Furthermore, although you will still be able to receive updates to your device via FOTA (“firmware over the air”), we do not guarantee that updating your device via FOTA will not render your device unusable. Please understand that you will not be able to return your device to the original state and going forward your device may not be held covered under the warranty for all claims resulting from the unlocking of the bootloader. HTC bears no responsibility if your device is no longer usable afterwards.
