Power reset or unknown upload mode

Hi, i have a problem with A750SN got stuck in bootloop. After i tried to enter download mode it shows me only “Power Reset or Unknown Upload Mode”, i have tried to connect it to Z3X and click on the “Reboot to Flash” the screen says OK but in the phone screen nothing is happening.

I will write the whole text that apears in the screen of device.
