Two Vita-specific problems block Apollo: the .vpk refuses to install, or the app installs but crashes on boot with error C2-12828-1. Both have known fixes.
Install Blocked: Enable Unsafe Homebrew
Apollo is homebrew that needs extended permissions. In VitaShell:
- Open VitaShell’s settings and turn on Enable unsafe homebrew.
- Browse to
apollo-vita.vpkand install it again, approving the extended-permissions prompt.
Also confirm you’re installing the genuine current package — apollo-vita.vpk, 7,343,637 bytes, SHA-256 25a3525efc49dd912b97b112c9b20cb333020b663cb74dc060de8697292d262a — from the Vita hub.
Crash on Boot (C2-12828-1): Plugin Conflict
C2-12828-1 on launch is typically a memory conflict caused by an aggressive background plugin (overlays and performance plugins are the usual suspects) rather than Apollo itself.
- Open
ur0:tai/config.txtin VitaShell. - Temporarily comment out non-essential kernel/user plugins (add
#at the line start) — especially overlay and overclock-style modules. - Reboot and launch Apollo. If it runs, re-enable plugins one at a time to find the culprit.
- Keep the conflicting plugin disabled while you use Apollo, or check for an updated version of that plugin.
Still Stuck?
Delete the half-installed app, reinstall from the verified .vpk following the Vita install guide, and make sure your homebrew environment itself is healthy by launching another homebrew app. If Apollo alone fails on a clean environment with plugins disabled, note the exact error and your setup and report it via the contact page.
