Troubleshooting

Haven't installed PlxNative yet? Start with the installation guide. This page is about what to do when something doesn't work.

The app tile does nothing

PlxNative needs webOS 4.0 or newer — older firmware can't start it at all, so the tile just does nothing when you select it. See Will it work on my television? for the full picture, including sets that start but hit a specific known problem.

Developer Mode removed the app

LG Developer Mode expires and removes every app it installed unless you renew the session before it lapses. Renew it in the Developer Mode app, or reinstall PlxNative if the session already expired. Installing Homebrew Channel through Developer Mode does not remove that requirement — only a rooted TV with Homebrew Channel has no expiry.

Sign-in doesn't survive closing the app

This used to happen and is fixed: PlxNative now keeps your sign-in in its own private storage, and uses the TV's key manager service where the platform provides one. If you still see it on the current release, use Details → Send report on the sign-in screen, or open an issue with your TV model and webOS platform release.

Playback reports jail_missing_rtkmem

This is a specific problem on Realtek k5lp/k3lp sets: LG's Developer Mode sandbox on some of these sets withholds a device (/dev/rtkmem) that native video decoding needs. PlxNative detects this and reports it instead of crashing. See the Known issues table for which sets are affected.

On a rooted TV with Homebrew Channel, the failure screen offers Repair, which asks Homebrew Channel's elevated service to patch the sandbox. Read the full repair procedure and its limits before using it: it only runs once per app session, and a timeout leaves the outcome unknown until you fully close and reopen PlxNative. Without root, there is currently no fix.

Don't use Repair for a plain black screen, a refused transcode, an unsupported codec, or any failure other than jail_missing_rtkmem — it addresses that one sandbox problem and nothing else.

Other playback failures

Try the current release first, then photograph the failure screen. Include:

  • your TV model and webOS platform release;
  • the PlxNative version;
  • whether the item was Direct Play or a chosen quality;
  • what happened after you pressed Play.

Report it in GitHub Issues.

If you're sharing an old event log, know that log redaction has improved across releases — a log written by a much older PlxNative version can still show an address that a current release would scrub before writing it. Where you can, capture a fresh log on the release you're reporting against.
