Welcome to AF kemot. I see this hasn't been answered in a couple of days so I moved it to your device's section of the forum in hopes for a better response.
I think this may be a situation where you have to perform a factory reset but I do not know how to on this device with it being locked like that. Hope someone can answer this for you in here. Possibly search for how to perform a reset in recovery in this section of the forums as well.
