AT&T stuck a massive blow to the development community when they announced that the AT&T One X won’t be a part of the bootloader unlock program of HTC’s. Without unlocking the bootloader, it’s nigh impossible to flash custom ROMs or make other such modifications to the device. But the development community didn’t sit and watch, and an unofficial method to unlock the bootloader was released just two weeks after the AT&T One X launched.

However, that method was quite complex and probably put off many users from actually using it. Well, say thanks to XDA Recognized Developer DesignGears, who has come up with the OneClick SuperCID tool for achieving SuperCID access on the AT&T One X, which also unlocks the bootloader along with it, without needing any fancy steps in order to do it. SuperCID access means you can flash any ROM or firmware on the device regardless of the carrier, which coupled with an unlocked bootloader will let you flash all the custom ROMs and modifications that your heart desires.

Let’s take a look at how the OneClick SuperCID tool can be used on the AT&T One X. Keep in mind that this will VOID your warranty.
