NVIDIA started rolling the Android 6.0 update out to its original SHIELD Tablet yesterday after getting the K1 variant on Marshmallow a few weeks ago. Things haven't been going awesomely for early upgraders, though. NVIDIA has pulled the SHIELD update while it investigates an issue that can break WiFi connectivity on the tablet.
A forum post from an NVIDIA custom care rep explains that following the SHIELD Tablet 4.0 update, users might be unable to turn on WiFi. In the case of WiFi-only tablets, that's kind of a big deal. It looks from various other posts that the update is setting the MAC address on some devices to 02:00:00:00:00:00:00, and there's no user-facing way to fix that.
NVIDIA suggests a number of troubleshooting steps like restarting the tablet, turning it off for a few hours, and sprinkling chicken blood on it while spinning in a circle. Okay, I made up the last one, but I bet it's just as likely to work. A factory reset seems to be doing the trick for some folks, but resetting your tablet should not be a necessary part of an OTA update.
It seems like most upgraders are doing just fine on Marshmallow, but NVIDIA is still holding off on the update out of an abundance of caution. The OTA will be restarted once the problem is identified. If you are unable to get your device's WiFi to work after updating, you can send a screenshot to NVIDIA. Details are in the forum post.
