This is a Chinese version. If you willing to try it on your device , you can but beware that It is just a beta version (Contains Bugs). So better you to wait for the stable version.
If you want to try in your phone, It can be upgraded to same manner.
1.) Download the firmware.
2.) Put in on your root directory of storage (Update.zip).
3.) Just tap on it, It will ask confirmation to removed App data. You have to check it, otherwise it may brick your device or may occur another problem.
4.) Then your device restart, Just wait when your phone is upgrading.
5.) Your device restarts, and your device is now flashed with Latest Flyme 7 beta version.
