I have a union repair tool I need help with

After the iPhone xs they will show an aftermarket or non original battery even if it's an Apple battery and it won't show battery health. I use a high quality battery and it uses the original texas instruments chip on it. It says it works on there home buttons so I bought the screen programmer for trutone and the battery attachment and the home button attachment was only 12 dollars each so I am curious if I can read the factory serial number and programming from the battery and put in to an aftermarket battery it might work. The problem I have with the home button working is if you have to pull the information off the home button it's not going to work because you only need to replace the home button if someone tore the cable so you can't read the information. But if you can get the information off of the phone and program it that will be awesome. I will let you know if it works.

@barriphone my bad, I did forget to mention the battery and display message they put up when you replace them. As far as the home button goes it may be a little tricky because it's not as easy as we may think. If we could use this tool all along, then why haven't we? I think apple is the only one capable of at least manufacturing replacement home buttons but if it does work, I supposed we could just get donor buttons off of other devices. Good luck!

It said it would only work off of their home buttons. So this might be a new setup and they are one of the manufacturers that come up with a lot of the new equipment to repair iPhones aftermarket so maybe they figured it out.
