The following is this year. I just purchased the dt pro tool. After two months of use, the following is my experience and suggestions on dt pro tools. 1: Lack of soul. That is to say, a tool should have a brand that only needs to be repaired. One or two brands. For example, the main brand is Xiaomi. Then update as soon as possible to support the latest models. Even if other dongles support. There is no update fast. In At this time, users will buy your tools. 2: The update is mainly for the world's mainstream brands, such as Samsung, Huawei, Xiaomi, Oppo OnePlus, etc. No matter how many supported brands are old models, they will lose their appeal. Just choose a few mainstream brands. It's okay. Not too much. 3: The update is mainly to update the glass lock to remove the account id. The flashing operation. For users, the simpler the use, the better. About writing the serial code and writing the blank board. The repair is a minor update. As users, we Most of the customers encountered need to unlock and have an account. Or need to refresh. Summary: The dtpro team is a strong team. It has also been number one in the world for many times. The tools are also relatively stable and reliable. Thank you. Send it when your team is testing. Some successful cases can be learned by novices. This is the best. There are pictures and the truth. More convincing. To be honest. Programming is also hard. It takes time and technology. So I asked the agent when I bought the tool. Is dtpro free for life? ? Because I don’t like software tools that are free for life. Because software tools need to be updated continuously. Servers are needed. It also costs. Free software tools for life are unreliable. I like renewal tools. Because of this, there is a guarantee of updates for life. I will not buy free third-party tools. I believe many masters will not buy either. Because it is unreliable. There is a risk of stopping the update at any time. This is the understanding of third-party software tools in the past 20 years of repairing mobile phones. Thank you
