ROM Update Utility (OTA) of Android 4.3 leaks for AT&T HTC One

A leaked RUU for an OTA update of Android 4.3 has just appeared on the web for AT&T’s HTC One. If you’re up to the task of flashing it, go right ahead and grab it for your phone. But watch out— the update brings an update to Hboot as well, so you won’t be able to access S-OFF via Moonshine or Revone.
We’re not sure what else HTC has added to the update, but we’ll let you know as soon as we get more information. Grab the zipped file in the source link below.
