Hello,

been using the MR3020 on 3.17.1 (130929) with a 3G modem for quite some time now. Because it crashed every now and again I thought I'd try the latest firmware (3.17.2 (140408)).
It upgraded just fine, but since I couldn't find a way to switch of Wifi on the latest firmware I went back to 3.17.1. The downgrade process looked to go flawless, but after the automated reboot the MR3020 seems dead.
No Wifi, no LAN, nothing, only the Power LED is lit.

Is it bricked or is there any way to get it back to life?

Thanks
