The alpha is now live in PlayStation 4, and will now run on all platforms until Wednesday at 9am.

Sony's latest PlayStation 4 update is causing the console to lock up when put in Rest Mode.

Reddit and Twitter users are reporting that installing Update 2.00 has meant their consoles won’t turn back on after entering rest mode. The only way around it is unplugging the device at the wall, but this runs the risk of damaging files and the console itself.

Kotaku staff are also having trouble with their consoles, and Gameplanet's is similarly out of action.

Sony is aware of issues with firmware 2.00, but there’s no word yet on when a fix will be applied. In the meantime, we recommend not using the PlayStation 4's Rest Mode.

The update has caused problems elsewhere too: the Evolve alpha test that was supposed to take place over the weekend never happened on PlayStation 4 thanks to problems it caused.

“We have some unfortunate news to share with folks planning to participate in the Big Alpha test on PlayStation 4 starting today,” developer Turtle Rock wrote on Friday night.

“Following the recent PS4 2.00 firmware update, we are experiencing difficulties with the Evolve Big Alpha on PlayStation 4.

“As a result, the test on PlayStation 4 is postponed. PlayStation and 2K are working together on a resolution. We know that for many of you PS4 players this is a big letdown.”

PlayStation 4 owners were gifted codes to play the alpha on Xbox One or PC instead.
