I have a zte vital/virgin mobile supreme. The phone is obviously past its support life with the last update being Jelly Bean 4.1.2. Would I be able to update this phone to the latest version of Android or to some previous version such as KitKat 4.4? If so can someone recommend a good, secure and stable ROM flash? Any foreseeable issues with flashing the phone or pitfalls I need to look out for. It's been a great phone for years and it still in like new condition so I'd hate to brick it.
