Oh, happy day, HTC One X users on AT&T. Root has finally been achieved on the device, and the instructions are actually relatively simple.
Those of you lusting over all the ROM development brewing for the AT&T One X were no doubt cursing the stars after updating to the latest 2.20 firmware. Aside from the usual bugfixes that typically come with an OTA (over-the-air) update, handset manufacturers usually take the opportunity to patch up root exploits, keeping bootloaders locked up tight (as per the instructions from carriers), and kept custom ROMs out of the question. This is exactly what happened on the latest 2.20 update, but it didn’t last long.
Last night, XDA member djrbliss discovered an exploit that, not only allowed him to gain super user permissions on the AT&T One X, but also crack open that prudish bootloader as well. The process involves gaining temporary root, and then using HTC’s own bootloader unlock tool to finally gain permanent root, where you can then flash custom recoveries and/or ROMs. With a Jelly Bean update coming down the pipeline, there’s no telling for how long this root method will work, but tis the cat and mouse game Android modders and the OEM’s play.
