it really depends. There are certainly things you could do to break it outright. you could also break teelemtry and have the normal mode work. You could not get it to work no error, but no extra power.
I do not normally get 7m of range indoors with no PA and the lowest power setting so it is likely you were successful, but it may well depend on the 2.4GHz noise floor in your house, or the receiver sensitivity, and this isn't a guarantee. Your best bet is to take it outside and see how far you can go before you lose contact.
