Firmware for Hipstreet Flare 3 tablet please

Hello,
Please forgive me as this is my first post.
I am looking for firmware to update via USB on my sons tablet. The details of it are as follows:
Hipstreet Flare 3
HS-9DTB37-8GB
Is there any other info needed? Was received as a gift for my son and I am getting an NVRAM error.
Thank you so much in advance!
Leon
