How to make a hard reset on Lenovo s920 China?

Question

Android

Hello, tell me how to do a hard reset on a Chinese lenovo s920, a friend "picked up" a large number of viruses ... I had an idea to do a Hard reset (I heard it helps), googled it, found a combination - power button + volume up, went to the menu (a little shock because everything is in Chinese), googled - found the item - # $% ^ (something in Chinese) MMC, nothing has changed after this manipulation, alas. I didn’t come across Androids ... somehow I did it on the Samsung, but there were points 1) wipe data 2) wipe something else, but here it’s darkness. At random I tried other points - some kind of tests. What to do then? I would not really like to reflash (there is little experience).

Do it through the android interface.
Go to Menu ----> Settings and find the item Backup and Reset there
