How to Fix Error Code 80020021
-
Restart Your PS3 Completely
-
Check Your Internet Connection
-
Retry the System Update via Settings
Do NOT power off the PS3 during an active update. Interrupting the update can cause further corruption or brick the console. -
Clear the PS3 System Cache
Restoring default settings will reset your system settings to factory defaults but will not erase game saves or user data. -
Update via USB Flash Drive
Only download firmware from the official PlayStation website. Using unofficial firmware files can permanently damage your console. -
Use Safe Mode to Restore File System
-
Rebuild the PS3 Database
Rebuilding the database may take a long time. Do not interrupt the process or power off the console while it is running. -
Perform a Full System Restore (Last Resort)
A full system restore permanently deletes all user data on the PS3. Back up everything important using Backup Utility before proceeding.

When to Call a Professional
If you have attempted all steps including a full system restore and the PS3 still displays error 80020021 or will not complete a system update, your console may have a hardware failure such as a failing hard drive or corrupted NAND flash memory. At this point, contact PlayStation Support or take the console to a reputable electronics repair shop. Additionally, if your console is still under warranty, contact Sony directly before attempting any hardware-level repairs yourself.Frequently Asked Questions
What does PS3 error code 80020021 mean?
Error code 80020021 on the PlayStation 3 means the system software update did not complete successfully. This usually happens because the update was interrupted, the download was corrupted, or there was not enough storage space on the console to finish installing the update.
Will fixing error 80020021 delete my PS3 game saves?
Most fixes — such as restarting the console, retrying the update, restoring the file system, or rebuilding the database — will not delete your game saves. Only the final option, a full System Restore (Safe Mode option 6), will erase all data. Always use the PS3's built-in Backup Utility to back up your saves to a USB drive before performing a full restore.
Can I update my PS3 without an internet connection?
Yes. You can update your PS3 offline using a USB flash drive. Download the official PS3UPDAT.PUP firmware file from the PlayStation website on a PC or Mac, place it in a folder called PS3 > UPDATE on a FAT32-formatted USB drive, then go to Settings > System Update > Update via Storage Media on your PS3.
How do I get my PS3 into Safe Mode?
To enter Safe Mode, first make sure your PS3 is completely off (not in standby). Then press and hold the power button. Keep holding it — you will hear one beep when it turns on, then a second double-beep after about 5-8 seconds. Release the button after the double-beep. You will be prompted to connect a controller via USB and press the PS button to access the Safe Mode menu.
Why does my PS3 keep failing to update?
Repeated update failures on the PS3 are usually caused by one of these issues: an unstable internet connection, a corrupted partial update file stored on the hard drive, insufficient free storage space, or a failing internal hard drive. Try updating via USB to rule out internet issues. If USB updates also fail, your hard drive may need to be replaced.
