    Downgrade/Upgrade Tab A Firmware w/o Tripping KNOX?

    Can I expect to be able to downgrade my tablet's T-Mobile firmware to the earliest available release and later restore it to the latest T-Mobile version w/o:

    1) tripping KNOX (currently 0x0)?
    2) losing ability to receive/install future OTA updates?
    3) losing data?

    Device is at latest version from T-Mobile and never rooted and rooting not sought. Have done this w a prior Tab w/o incident.

    I had no audio and I unplugged my headphones and realized half of the headphone jack was still connected to my vidmate headphone cord and hasn’t worked since.
