Two related failures hit PS4 users: the package installer refuses the Apollo .pkg, or Apollo installs but crashes on launch with CE-34878-0 (the PS4’s generic “an error has occurred in the application” code). Work through the checks in order.
1. Verify You Have the Genuine Package
Most install failures are a bad download. The official v2.4.0 package is IV0000-APOL00004_00-APOLLO0000000PS4.pkg, 22,806,528 bytes, SHA-256:
ec34add4d2857fa3c947ed5666735a5c35ddb3e47d8be925b36e9ad408f7c090
Anything else — wrong size, wrong checksum, a renamed file from a random mirror — should be deleted and re-downloaded from the official link on our download page.
2. Check the Install Environment
- The console must be in its jailbroken state when you install; a fresh boot without the jailbreak applied cannot install homebrew packages.
- The .pkg goes in the root of an exFAT/FAT32 USB drive.
- Remember Apollo itself (since v2.0.0) needs no GoldHEN/ps4debug payload to run — but you still install it through whatever package installer your jailbreak setup provides.
3. Clean Reinstall for CE-34878-0
- Delete Apollo from the home screen (Options → Delete) — this removes the corrupted install; your saves are separate data, and you should already have backups.
- Power the console fully off and back on, then re-apply your jailbreak.
- Reinstall from the verified .pkg.
- Launch Apollo before reconnecting any external drives with save folders, to rule out a malformed save file crashing the browser view.
4. If It Still Crashes
Note where it crashes: on launch (installation/environment), when opening a specific save (that save’s data is damaged — restore its backup), or when opening the Online Database (network — see database not loading). A crash tied to one save is covered in corrupted save after re-signing.
