Of course. It had to happen at some point in space and time: while HTC was providing an unlocked bootloader for some of its devices, it turns out that not all the new devices will get the treatment they deserve. Enter, the AT&T 4G LTE version of the HTC One X, where it seems as if this is the start to a new trend:
HTC is committed to listening to users and delivering customer satisfaction. Since announcing our commitment to unlockable bootloaders, HTC has worked to enable our customers to unlock the bootloader on more than 45 devices over the past six months. In some cases, however, restrictions prevent certain devices from participating in our bootloader unlocking program. Rest assured, HTC is committed to assisting developers in unlocking bootloaders for HTC devices and we’ll continue to unlock additional devices in the future.”
That was HTC’s statement on the matter. Obviously, AT&T is to blame. But it’s not an issue to precipitate over — the Android ROM community has always found ways to bypass the locked bootloaders of Android devices, and they will “most likely” continue with the HTC One X.
