PlayStation 4 firmware 2.0, codename Masamune, had some lovely new features but also caused a few consoles to get stuck in “rest” mode and not respond to wake up attempts.
Sony have now released a new firmware patch, V2.01, and it is available to download now and should sort out the niggles from the previous update.
That said, the patch notes are the usual “System stability during use of some features has been improved,” so we’re assume the problem has been nullified. PlayStation tweeted earlier this morning that the problem would be fixed.
PS4 software update v2.01 is coming soon, and will address issues some users have encountered when powering on the system from Rest Mode
