Can you upgrade my tablet to Oreo?

We can guide you but we don’t offer repair services here directly. This site is supported by volunteers. While some offer their repair services you’ll need to review their name card for contact information. Keep in mind we have people from all over the world asking questions so without knowing where you live I would hate to aim you to the other side of the planet ;-}

Have you tried talking to Nvidia support? Not all Android based devices can be upgraded.

well the short answer is No , this tablet latest update is Android 7.0 and Android 8 is 1 year old so if Nvidia wanted to upgrade it to Android 8 they would do it along time ago and do not root your device in order to upgrade it, it is very danger
