2 problems after flashing my MXQ Pro 4k

Hi all

I am a newbie to this forum .
I flashed my box with aiden AT9 s905X 1G/8G , it flashed succesfully but the remote control stopped working which is um4/r03 .
Also it is not connected to USB Burning tool any more and could not reset the box with the toothpick also.

Any solutions to those issues?

Regards
