I love these videos - keep up the great work. I am having problems extracting the TL-MR3020 firmware with ./extract-firmware.sh ../TL-MR3020/mr3020nv1_en_3_14_2_up(120817).bin. What I get for output is a ton of warnings and the following:
Scan Time: 2015-12-16 15:36:43

Any ideas on where I am going wrong?
