Help !! Brick G2 Mini d620r

Good afternoon. First, sorry for my English and sorry if this is not the right place to post this, I'm new to the forums. I tell you. Yesterday I tried to root my g2 mini d620r following the instructions on the page htcmania .com/archive/index.php/t-906952.html . The problem comes in the 10th step. After turning off the phone, no restarts. It seems that evil ran the order and there is an error in the boot file. The phone does not turn or make any attempt to turn on (the logon screen does not appear lg or anything), I connect and nothing comes out. just a screen when I remove the battery and plug in the phone. I need help please. Thank you !

Attached the link to the photo that appears on the screen mobile.
So is the screen when I plug without battery (no space - OneDrive): 1drv .ms/1K8y6vI
