Wireless Joint

I have the recovery mode up, although the page is in Chinese.
Nothing seems to work; the lights do not appear in the documented sequence.

Does anyone have this issue or know what I'm doing wrong?

Click on the large pill shape in the middle. It will ask for a file. Select the NEXS2GO firmware file you have. Then click ok. It will upload it, then if I recall it will have another button that is basically the final "ok/yes/Im sure" and then it will flash the firmware.
