Sony recently released the version 7.50 update, a minor update patch, for the PS4. But many users have found that it will cause the device to fail to start after the update.
Some users posted on Reddit that the device had some problems after the 7.50 patch was updated, including the bug that it could not start or even restarted indefinitely. At the same time, some users encountered the embarrassing situation that the PS4 can be turned on but there is no signal, and it does not help after restart.
To avoid this situation, users need to exit the CD before upgrading the system firmware.
Some users who have encountered this problem can press the host switch for 10 seconds to enter the safe boot mode, and then install the 7.50 firmware update through the U disk.
