The instructions for the Aircraft tell me to just read the .txt file at the end to see if all went well, and that the process can take up to 25 minutes - that part is fine and makes sense. But with the P2 Series, if my memory serves me correctly, the instructions gave clear indication that the FW update was underway through the flash sequence of LED lights. But, with my P3, the instructions are not so clear. I have rapidly flashing yellow, and that's been going for about 20 minutes .... Is this what I should be seeing? Thanks for any help on it!
