AT&T has taken down the stock 4.1 UCDLK3
For no valid reasons AT&T Galaxy S3 stock ROM I747UCDLK3 has been nowhere to be found for download.
Both links from Sammobile and Samsung-updates only says "This file is either removed due to copyright claim or is deleted by the uploader"
There must be something fishy goin on right here, they don't even released the full stock of recent UCDMG2 update. This is the first time I heard somebody filed copyright infringement of those stock firmware? Why the heck it's only the UCDLK3 and not all other older stock versions like LEM and LG1. So watch out AT&T subscribers!
