Since you’re on CFW 4.85 CEX, here’s a basic roadmap to get you back up and running:
Check your CFW – make sure it’s properly installed and not corrupted. If needed, reflash your 4.85 CEX CFW using the latest PS3Xploit or Rebug tools.
Update tools – grab the latest multiman or webMAN-MOD for file management, backup, and homebrew support with

Backup your data – always a good idea before doing anything major. Use an external HDD or a USB drive.
Homebrew apps & games – reinstall any apps or games you used to run. You can also check the PS3Xploit community for updated homebrew versions compatible with 4.85.
Optional: downgrade/upgrade hacks – if you ever want to move to newer firmware features or certain mods, check guides for safe methods on 4.85 CEX.
Basically, your system can run most homebrew and backups right away, but updating your tools and making backups first will save you headaches.
