Bad Recall Tablet

Hello people, last week i received my recalled tablet. I tried to turn it on and the first screen was the bootloader (see img below). Everytime i try to turn it on, the same bootloader screen apears, so what can I do? Obs: It came with Android 4.4.2, and its says there is up to date(i cant update to 5.1.1). What can I do? Complain to NVIDIA and try to get another recall? Or is there a fix for it?
Thanks in advance
