End of easy-installer on GS290 blocked

at the end of process, the programme is blocked

and , on the smartphone, there is written, in a black screen, in very small letters “FASTROOT MODE…”

could anyone help me ?

When you now press the volume buttons on the device, can you change Fastboot to restart, then confirm with the power button?

I’ve solved the issue. It was the adb driver that was not completely installed on my PC !
The “fastboot” menu is written so small that you need a magnifier to read it. And have to know that the Vol+ & Vol- buttons are necessary to choose …

thx for your answer. It’s nice to feel the community ready to help
