This just started after an update. It was working fine before.
The model is the p2571. When I start it up with the new style controller (this is all I have) connected it says to unplug USB, I do this and nothing happens.
I tried it without it plugged in and when I turn controller to pairing mode it just sits there flashing.
When I boot the device with a USB keyboard plugged it goes into initial setup mode but it will freeze completely after a few seconds and need to be unplugged to restart.
I also cannot for the life of me get the thing to show up using adb or fastboot and I also cannot get it into recovery mode at all using the hardware button or by holding a+b on the controller.
Is this thing completely fucked or am I missing something?
Sounds like it is fucked. Contact Nvidia for a RMA.
