Xiaomi 2S accidentally pressed the wrong key when updating the Xiaomi lock screen. The system program displayed now is inconsistent with the signature, and the installation failed. The upgrade of this version has been automatically ignored. Hi!

Please don't worry. I suggest you back up your important data first, and then brush the whole package (I suggest you brush it to the latest development version) before using it to see if there are any problems you described. Please choose the address of the brush package according to the model:/Brush Tutorial: Detailed Tutorial of 6 kinds of brushes for Xiaomi mobile phone-Pay tribute to Brother Guanyin/Thread-7106164-1.htmlPlease use the sixth brush method and encounter brush problems: Xiaomi mobile phone driver, brush the machine. Address and telephone enquiry:/service/post office

A more detailed description of the problem will help netizens understand your troubles and help you solve the problem more accurately. Thank you for supporting Xiaomi mobile phone!
