How to reset unifi ac lite (solved)

Yesterday I was trying to install the lede firmware for my device (Unifi Ac lite). It has only 1 port LAN. After installing finish I change it to WAN but I forget to enable wifi and I can't open LUCI web interface. I try to press reset button, but nothing happens, someone can help me. Tks.
Problem with reset button, hard to press and hold it.
