AT&T HTC One X Root For 2.20 Firmware Is Up And Running

We are aware that many of the HTC One X users that purchased the smartphone from AT&T were desperate for a root solution, as the latest firmware version (build 2.20) was causing some serious problems for the hackers.

When 2.20 firmware update for AT&T HTC One X was released it brought the usual bug fixes, but the software engineers working for the biggest carrier in US also thought that it would be “nice” to patch up root exploits, locking the bootloader so tight that no one was able to find a way to bypass the S-ON protection. Djrbliss found a way to root AT&T HTC One X on 2.20 firmware and he was kind enough to post the solution on XDA Developers Forum.

The main challenge was to find an exploit that allows the users to write to /system partition, as the S-On for 2.20 firmware brought an annoying lock for the NAND partition. Our hero has found an exploit that now allows you to have a “permanent root” on your AT&T HTC One X running on 2.20 firmware, but you won’t be able to perform it without unlocking the bootloader.

As you probably know, a procedure like unlocking the bootloader of your device violates AT&T’s terms and conditions, therefore the warranty of your device will be voided. Even so, if you know what you’re doing it’s a small price to pay given the opportunities and the customization options the root solutions brings with it.

HTC One X is world’s first smartphone underpinned by a quad-core processor, but since the limitations of the Nvidia Tegra 3 chipset, the Taiwan-based phone maker developed a dual-core model for the US market, which is compatible with the carrier’s 4G LTE networks.

AT&T HTC One X packs a Snapdragon S4 chispet based on two Krait cores clocked at 1.5 GHz, Adreno 225 GPU, 1 GB of RAM and 16 GB of internal storage. The smartphone boasts a 4.7-inch Super IPS LCD2 dispaly with HD resolution and Gorilla Glass 2. The 8 megapixel camera brings full HD video recording, autofocus, face and smile detection and simultaneous HD video and photo recording.
