Since it’s a Chinese page, it’s showing the instruction in Chinese.
The phone really sucks, I mean I’ve used it for a couple of years, its camera and battery function is too low. See review here: http://www.china-prices.com/phone/765/thl-w100
That’s why I rooted the phone, still not satisfied 
anyways here are the instruction:
-factory model
-complete testing
-single testing
-test report
-Reset the mmc
-Information about the Version of the phone
-restart the phone
Most phone has the same function.
