Install PirateBox on MR3020 5 hours and blinking

Hi,

I’m Installing PirateBox on TP-Link TL-MR3020 using openwrt-ar71xx-generic-tl-mr3020-v1-squashfs-factory.bin firmware. I’m using SanDisk Ultra Fair (USB 3.0 32GB FAT32). I’m following the instructions in this guide [piratebox.cc]

I’m at step 3 D and it’s almost 5 hours and the router still blinking. Here’s a video

I’m using Windows connected to the router vie Ethernet.

Is my router bricked? What I’m supposed to do?
