Recently, many netizens asked about the certificate. I summed it up based on my experience in playing mobile phones for several years. There are two ways to sign software. First, online signing. For example, you can register a user in the soft bar of mobile phone, and then enter your mobile phone serial number. After 24 hours, the certificate will be ready. If you have unsigned software in the future, you can log in to this account and use the online signature function. Then you can download the signed software. You can choose one according to your own needs. Two: to make a mobile phone certificate, you can generally go to Saipan Forum or Pickled Pepper Network to make a mobile phone certificate. The method of making the certificate is the same as above, but it can be downloaded after it is made! Saipan Forum issues certificates after eleven o'clock every day, and there is a quota limit, that is, a certain amount of certificates are issued every day. Pickled pepper network is divided into time periods, you can log on to the website to learn more! Make the downloaded certificate and key and put it in any folder of your mobile phone or memory card, as long as you can find it! Then you download a free signature software and install it on your mobile phone. Open the software, then import the certificate and key, and you can sign the software! The signed software is different from the original software. You can set the location of software output after visa in the software. Then install the signed software!
