    you have to flash the new firmware with micro sd card. seems you brick your device.

  5. Simon, Did you fixed your problem.
    I had same problem with screen staying on T7s screen. My problem was a Modified Google Play. I had to reinstall the fresh ROM into a system.
    I did not installed the Update. It is a Beta with problems. But I found it on Internet a T7s CleanROM. which is Also a Rooted.
    What you have to do is.
    UN-zip ROM file to the SD card to root directory. Best way be sure that there is no other files on it.
    Hold POWER and VOLUME (-)………. NOT THE (+) but (-)
    Reboot the Tablet while holding those buttons. (I had to do with a pin hole reset)
    Then you will on the screen installing.
    After install your system would be ready.
