Problems with communications using arduino IDE and ESP32

[molBR123]

So I was testing my esp32 normally, doing the simple stuff, and I wanted to test one of its wifi examples, most specifically the "SimpleWifiServer". So I uploaded it on the board and now I cant upload anything else on the board... the blue led that was always blinking dosent blink anymore and I dont know what to do, any thoughts?

I am using ubuntu 16.04 as operating system
