I had a lot of problems getting my Boyue T63 rooted. I followed the instructions in this thread and still had trouble. This post is to share my various solutions, because I was able to Root my Boyue T63 and run a working Google Play Store and Google Play Books on it.
Problem loading the Drivers. To fix...
I made the mistake of not Extracting the Zip file with the Drivers. You must do this in order to have Windows install the drivers. It will fail each time if you have not extracted the Zip container into a normal set of folders.
The device would show up in Windows 10 Windows Explorer, but it did not show up for ADB, and could not be accessed to run the Root batch file.
I struggled, then finally...
The key to getting it to work was to
1) Enable Developer Options
Go into Settings. Then tap About Device.
Then tap Build Number 7 times, 7 taps on the build number will enable Developer Options
2) Enable USB Debugging.
If you are still in the Settings section for About Device, you will need to go back a screen, to your Settings main page, now { } Developer Options will be visible. Tap on Developer Options and then tap the check box for USB debugging.
When USB debugging is checked the steps in this thread for running the Root batch file worked fine.
I did have some further problems, since I had attempted to install Google Play through an alternative marketplace, called Good E Reader.

I tried a few version of Google Play, and the problem I had was that I could download apps, but they failed to install. I installed the app Nova Launcher from Good E Reader and was able to find an app on the Boyue called APKInstaller, which I used to Manage to uninstall versions of Google Play that were not working, and try different versions that I had downloaded. The version the worked for me to install the apps correctly was version 7.6.08.N-all [0] [PR] 149245622
It may have been the one that I downloaded from Good E Reader, it may have been one that got pushed on my T63 from the Root batch process. I am not sure, but if you have trouble after rooting and try to use Google Play, then use your browser to go to the webpage for Good E Reader and download the versions available there. One had the name Google Play for E-ink, and the other was just normal.
I mention all these details in case it helps anyone. I really struggled and didn't know how to get this done and wasted a lot of time, so if I save anyone time, then I am glad.
One thing I notice about using the T63 with regular Android apps is that the apps are not built for black and white and many apps lose the kind of contrast that the E-ink is capable of, and look very bad frankly. I don't think it is the quality of the actual screen, but the apps using the screen as if it could do color. I notice that when I move through different screens they actually show me much clearer contrast as an intermediate process, then land on the washed out greyscale. Too bad. So the task was to find an Ereader app that worked best, and could select a plain untextured background.
I found AIReader to have some color options to help.
And the app that comes on the T63 called FBReader was also able to produce very clear reading screens.
The color problems really show up on the Library screens where images or icons are showed. This is true of Nova Launcher and other apps.
That is what I felt might help people to share. Good luck, if you are thinking of buying the T63 you should be confident that you will be able to Root it and run Google Play and Google Play Books on it. I had to update the Google Play Books app to get it to work, but it is working now. That was the main reason I bought this Boyue T63, to get an E-ink Reader for Google Play Books. That works now, so far as I have tested. I haven't tried to buy books or anything, but to download and read it seems ok.
