I only provide the concept and the logics, you can't directly and easily solve a key with my scripts, first you need to work with scalar to learn how each key reacts to different numbers when divided.

Now I see why you are confused, sorry for that, here use this one I posted here https://bitcointalk.org/index.php?topic=5469636.msg62964103#msg62964103
Just replace scalar_1 and scalar_2, start range, end range with above values.  Also set this line for i in range(start_range + (start_range%2), end_range, 1):  make sure it's 1 instead of 2, I bolded 1 to make it easier to notice.  When you learned how it works, Let me know and I will point you to a script using public keys instead of scalar.😉
