HTC previously confirmed that the Android 4.3 update will be available to the U.S. and Canadian HTC One smartphone models as well as the HTC Droid DNA before September 2013 ends. Now, the pre-release version of the latest Android update which is accessible as custom ROM has been leaked in advance to its official release date.

Maximus HD ROM Developer LlabTooFeR leaked the Maximus HD 12.0.0 ROM on XDA Developers based on the firmware version 3.09.401.1 with the promise of releasing the untouched HTC firmware version on Wednesday, August 28, at 10 a.m. GMT.
