I really love OpenWrt firmware and the wonderful community. I tried to use OpenWrt with my NETGEAR R6120 for about a month but found out that a bug is causing pretty unstable Wi-Fi whenever I am trying to download a large file. Unfortunately, 95% of my devices are connected through Wi-Fi. This why I am thinking about going back to stock firmware for now. But I will be back, I promise.
Could anyone please tell me that how can I go back to factory firmware without bricking the device? Thank you for your time.
