(2) Copy the downloaded ROM "xxxxx.zip" to the root directory of the memory card (www.nubia.cn Nubian official website Forum downloads the corresponding card swiping package).

(3) Press the power button and the "Volume Increase button" at the same time, and then release the power button to enter the recovery mode.

(4) Select wide DATA/ factory reset, and then select Yes-delete all user data/.

(5) Return to the main interface, select the WipeCache partition, and then select Yes-erase the cache.

(6) Return to the main interface and select Install.

Select p from the sd card (select Update from SD card), and then select Select.
