Learning from my last experience, I wrote down the HA and AAA keys in the event that they got wiped out. Well for some reason, when I flashed the stock firmware they got toasted. But luckily I have the keys...only one problem - I don't know how to write them. I tried "writing" instead of "reading" when following the guide to get the keys, but it doesn't seem to save. Does anyone know how to properly re-write these keys?
