Zebra TC75 boot screen always

Hello all,

i have a device under android 7.0 (tc75x) and actually i make some test with soti mobicontrol.

I have make a profile with soti and black list some application for some security reason.

The profile is well installed, and app are disappear from the setting of the device.

Great ..

But i reboot the device ..and now since more hours the screen is always on boot ..

I've try to push (scanner + volume up + power) for 4 second -> device well reboot ...but every time the device is still on the screen boot (wait screen).

any idea, what i can do for to solve this problem ?

thanks
