Recover Tp-link C6 after update

I had installed the openWrt firmware on the Tp-link C6 v2.
I ended up leaving it at the company and tried to put the original factory firmware on it. Now it just turns on, only the power led is on. The resturer does not appear. Even putting a network cable, it does not indicate anything. If you can help me recover this device I would appreciate it.

so whats on it, original FW or OpenWRT ?

And did you try to reset it ?

A tp-link firmware was placed, but it did not restart. I believe you are with her.
