The OnePlus One was a phone developed by a company made up of ex-Oppo employees. They recently released the first OEM built phone with a custom Cyanogen Mod 11 build preinstalled. The OnePlus One is pretty similar to the Oppo Find. Today we learned that the custom OnePlus CyanogenMod 11S build runs on the OppoFind with little modification. The rom from the OnePlus One has been ported over to the Oppo Find 7a thanks to the upload of the OnePlus One's CM11S update.zip and some modifications made by developer "Rayfin'. You don't actually have to flash the modified version for it to work on the Oppo Find 7a though. Apparently if you just flash the OnePlus One recovery to the Oppo Find 7a it will take all OnePlus One updates. However not all is perfect with the unmodified rom. Front facing camera, microphone, wifi, mobile data, sound, gps, and telephony will work, but the voice wake function, and NFC will not work. Also the device will only show 3GB of storage which is a huge bummer. In its current state this is not much of a daily driver rom, but with a bit more tinkering this should be more than useable soon.
