Hello,
have you ever heard of Generic System Image?
Your phone is also listed there, you could use the “b” image.
It is an image for many phones, not phone specific. It can run well, but there could also be errors.
You would have to test it to see if it runs well for you.
You can get the image file from here: https://android.l1nux.org/index.php/s/tNyG9ZcrjGBPrdH I try to create a new image about every 10 days.
