16.0.0.210

Bought a used phone, now an "orange state" warning appears, telling me it can't be trusted - what to do? Hey everyone, So, I've just bought a used OnePlus13 via eBay (private, bought via PayPal). Today it arrived, but I'm really confused about the warning message that appeared as I powered it up: "Orange state - Your device has been unlocked and can't be trusted" So, what exactly does this mean? I can't risk using a compromised mobile phone, as I intent to use it for things like online banking. For your information, this was the seller's additional description regarding the fact that it's a chinese version: *Important Technical Information (Please Read):* *This is the Chinese hardware version (model CPH2649). It is identical in construction to the global version but has two distinctive features:* *No eSIM Support: The device has a dual-SIM slot for two physical nano-SIM cards but does not support digital eSIMs.* *Software flexibility: Currently, the global software OxygenOS* [*16.0.0.210*](http://16.0.0.210) *(based on Android 16) is installed.* *Advantage: Full Google Services, German language, and the familiar Android design.* *Note: In this configuration (Cross-Flash), automatic Over-the-Air (OTA) updates are not supported. These would need to be installed manually.* *Optional service: Before shipping, I’m happy to switch the device back to the original ColorOS upon request (which includes OTA updates, but primarily features English/Chinese system languages).* When I ordered the phone, I wanted him to switch back to the original OS, as I do want OTA and have no problems with an english system. So, what do I do now? I'm completely lost here and need advice.
