Default [Q] (Q) D2 pad tablet model: D2-927G

My D2 tablet is rooted, for some reason when I turn on my tablet it boot loops. I can access the recovery mode and I have tried formatting cache and doing a factory reset but nothing seems to work. Do you guys have any suggestions? Any help will be greatly appreciated.
