My mobile phone is Nokia X6, and I want to download some software. After downloading, I will say that the installation failed. Before downloading, these softwares all said that they needed to be signed. 555 ... Me, too ... Because of the internal reasons of foreign websites that manage Saipan, the Saipan certificate can no longer be made, and there is no way to do it at home. If the landlord's machine is parallel, it can be brushed, so it will not be restricted by the certificate. If it is licensed, it is recommended to brush the machine after the warranty period, because there is no warranty after brushing the machine.
