Yeah, that "recovery" screen that you get is actually a tool for hardware testing purposes, and those "FAIL" texts are indicating that the hardware tests they haven't been run yet. And Those buttons one of them is to change the language of that screen (the button that only has two Chinese characters) but if you have unlocked your bootloader and successfully flashed the custom recovery using the TWRP flasher. You can access TWRP by tapping the button that says in Chinese between parentheses (recovery)
