That update had GMS removed so Google no longer works. Options are first see if your phone is able to do rollback and go back to previous rom. Not sure if you need to unlocking bootloader for this. Other option is to change from Chinese rom to another to do this you need to unlock bootloader in and you can never lock it again or you will brick the phone.
