Hello, I don't think I can check the SN anymore: the tablet won't boot, and adb doesn't recognize it anymore. Is the S/N printed somewhere on the tablet ?
As a side note, I just received the information from NVidia that the tablet has been shipped and should arrive tomorrow, maybe that triggered the kill switch yesterday.

Ah! I kept the power button pressed for a long time (30-40 seconds), and then powered it to bootloader: success ! I probably entered the APX mode without knowing and confused it with the kill switch.
I'm not reflashing to 5.2.2 and will nomoreOTA ASAP.
My day is better now
BTW, the SN check says that next OTA is 3.1.1, which is odd because the last OTA I received was 4.4.
