Nice work getting your XT1965-T up and running! I went through the same experience and finally came out the other side before seeing your post. I think flashing e to both A and B did the trick but i had another issue as well.
One thing I and at least one other user encountered was a problem where the phone would loop shortly after being unplugged from the USB cable (from computer). Phone would boot into e just fine and work perfectly until the USB cable was disconnected then it would loop and end up at a recovery screen saying that a factory reset (or similar) was needed and it couldn’t boot into the operating system.
Did you encounter this?
After two days of this, mine magically “fixed” itself and has been fine ever since. I’m looking for clues to prevent this if/when I flash a newer version of e.
My guess is that there was some communication going on between the phone and the computer via USB that, when broken (unplugged), would cause the loop. But I really can’t back up that idea at the moment.
I hope your phone is working well and good luck out there.
