This is a mess. I don’t have any of these files in my /storage folder, including .config or anything like that. I found a command to resolve defining the factory shipped remote with the MeCool M8S W and the procedure that works is here: [Solved] Mecool M8S Pro+ not working . It appears the software has been vastly changed since this thread was started. Pity anyone trying to get an answer on how to add a remote - there needs to be a wiki on it.
