698/5000



  
I tell you to see if someone can help me.
Tried to unlock the bootloader with the flash tool, I gave the format + download option I had seen in a video and left the phone with the black screen, it did not turn on or in recovery mode. Today I tried, even with another computer to see if I could install the damn drivers to revive the phone, a mediatek driver appeared to connect it but I did not recognize it flash tool,
One of the times I tried I have downloaded to the flash tool with the phone without removing the usb and now when I connect it tells me that it does not recognize the USB device, on any PC.

Can you do something?
Is the phone no longer useful?

Thank you
