I received my MangoGT device and connected to DHCP router, I logged in to mango. I tried to setup DHCP to Static. It didn't work and I had run few commands such as sudo reset. Now I can't reach and log in to MangoGT although it shows up in my network when doing IP scan. Moreover, Ifconfig doesn't show the DHCP IP. How can I regain access and how can I set up Static IP (I had followed the instruction from Docs-v4 MangoGT)?
