Sony will release a non-lethal version of its PlayStation 3 4.45 firmware update on June 27. The since-pulled patch rendered "a small number of users" unable to access their PS3's interface after patching--in other words it soft-bricked their systems.
A community manager said Sony has isolated the issue in a post on PlayStation's official U.S. forums, and a new system software update which resolves the issue will release on June 27.
Of course, users who had problems with the first patch and were left sans interface can't install the update through typical means. The community manager said Sony will provide instructions to implement a solution alongside the new firmware update.
