I doubt it had anything to do with the battery change. It's probably just poor, coincidental timing. There's a high probability there's nothing you can do. You can try to contact customer support, but it might be for naught. Error 29's like a death sentence. But anything's worth a try. I'd try through the game first, and then if nothing happens, try customer support through the LINE app directly because the Terms of Service are provided by LINE Corporation.

If there is a small chance that the battery change did trigger something and reported a false positive, you can always hope for that. Good luck on your forthcoming trials and tribulations.
