Yes i did also failed the first time....i did confuse the FW from the other drone, with the advanced...lolol
Good lord, it refuse to update!
Then i did download the correct one, and no issues.
I suspect of small details people miss: For instance, in Windows, check the option to see all folders ON...they probably miss the one thats invisible, and the update process fails...but its just a guess ;-)
P.S: Also, following that idea, i had to update to 1.2.6, then 1.2.8, and finally, .1.3.2.0....which is unreasonable...
The instructions of DJI only refer about the RC been update with 1.3.2.0....like you said above and well.
