PS5 Error NP-102946-2, “Please Install the Latest Update File”
NP-102946-2 appears when the PS5 needs a newer system software update file than the one it has. It usually shows up when starting a game or app that requires newer system software, or when an update has not finished installing.
The fix, in order
Connect the console to the internet and install the update: Settings, System, System Software, System Software Update and Settings, Update System Software.
If an update is already running, let it finish. Starting a game or restarting the console mid-update can interrupt it.
If the update fails, free up storage space: Settings, Storage, and delete games or apps you no longer play, then try the update again.
Restart the console fully and retry the update on a stable connection, using a wired connection if Wi-Fi keeps dropping.
If the internet update keeps failing, update using a USB drive: download the latest system software update file from PlayStation's official site onto a USB drive formatted to FAT32, in a folder named PS5, inside a folder named UPDATE, then start the console in Safe Mode and choose Update System Software.
Only download system software from PlayStation's official site. Update files from other sites may be incomplete or altered, and installing one can leave the console unable to start.
If it still happens
If the console has plenty of free space and a stable connection but the update still fails, try the USB method above, and check that the update file name and folder layout match PlayStation's instructions exactly. If the USB update also fails, contact PlayStation Support, since repeated update failures can point to storage trouble.
Common questions
What does NP-102946-2 mean? It means the console needs the latest update file installed before it can continue. It is an update prompt, not a hardware error.
How much free space does a PS5 update need? Updates need enough free space for the download and the install, which can be several times the update file size. If space is tight, deleting a game or two usually clears the way.
Can I keep playing while the update downloads? Yes, in most cases, but do not turn the console off or start the game that needs the update until the install finishes.
