Just a quick question before I try to get an RMA setup with my AC66U. I had previously had the router repaired/replaced but had ASUS's stock firmware on it at the time. Now, the router died with a recent version of Asuswrt-Merlin installed. My question, will ASUS throw a flag at this? I can't get logged into the router anymore to flash it back, as it just completely died this time.
