Wait, but the user wants a global link. Oppo's firmware is usually region-specific, so maybe there isn't a single global link. That could be a problem. I should mention that and suggest using a mobile network or altering browser headers to access the regional link they want. Alternatively, maybe there's a third-party repository that offers it. But I need to be careful about recommending third-party sources as they can be risky. So maybe it's better to direct them to Oppo's official site and provide steps to access it without region issues.
