Hi and thanks for using JustAnswer. My name is Eric and I do whatever I can to help answer your questions.
Do you know the Google Account username that you register or logged in with when you first setup the phone?
The unfortunately the only option left is to factory reset the phone by booting into "recovery" mode.
how u do this
Remove the battery from the device, and replace it but do NOT power on the phone.
We may have to try a few different ways as your phone is not in the "main" model lines (like the Galaxy devices) so there is very little information on it.
Here is the first set of steps to try, youve already done 1 and 2
Ok, let me look up a couple things..
Ok, do you have a camera button on the phone?
Ok, I will research more of this phones model and find out how to get it into recovery mode. This is the only way we can reset the device.I will let you know when i find something!
did you find out anything for me
