Huawei P Smart Pro STK-L21 is getting an EMUI 12 update in the European Economic region. STK-L21 is the most complex model released by Huawei. It’s really difficult for users to identify which model they have. By looks, all variants of STK-L21 look the same but have different firmware versions. In this post, we are sharing the EMUI 12 update method only for devices with the C431 cust version. And strictly not for the P smart Z model. You can identify the model, by going to the project menu, dialing *#*#2846579#*#*, and checking software information, if it shows you STK-L21UDV then your phone is P smart Pro.
