Hi all especially Donnie and the gang. I’ve read more posts and watched so many videos to this issue.
It's nice to see someone do a little research before they reach out to the forum. As many will testify, vague questions with zero research are kind of a pet peeve of mine. Kudos to you on that front.
I have downloaded all the previous Inspire V1 and Pro firmware versions
Per Brian Fist (a forum member who hasn't contributed to the forum for a while), it matters *where* you get your firmware from. Apparently DJI has done the unspeakable and tampered with existing firmware versions withOUT amending the firmware version number. I can't confirm if this is true or not, but Mr. Fist knows his s***. The unfortunate reality is that I have no idea of knowing if your firmware v1.08.xx is the same v1.08.xx I have.
Remember; the two reasons for rolling back are reception issues and erroneous NFZ issues with the later versions. So an easy test is to fly before and after missions to see if your video reception gets better. The difference is profound. That would be your "canary in the cave" if you will.
Currently have 3 Inspires, all with C controllers and all marked a T601 V2. One has a X3 the other 2 have X5’s. All are running 1.11.50, RC 1.7.8 and the current iOS go version.
I was going to downgrade 1 to run the sweet spot AC 1.8.1 with RC 1.6
I’m not going to use the X5 to downgrade , I will use the X3 due to me bricking a previous X5.
Good deal. You are right on the mark. The "X5 bricking" thing didn't flush out until after I had made my video. I used the X3 cameras for all 3 roll backs. I stated no caveats regarding the X5 because I simply didn't use my X5 to roll back the firmware. Unfortunately, others who didn't have an X3 camera experienced various levels of bricking, including Brian Fist. Maddening. But, yes, DO NOT use your X5. I have tested my Inspire with 3 different X5 cameras all running various flavors of firmware and all X5's worked perfectly. So you shouldn't have to worry about your X5 not working with your rolled back drone.
My question if you don’t mind:
Can I use the current IOS App version?
I assume you're talking about using the Go App (iOS version) to roll back your RC. I can't answer that, as I have never installed the later versions. You will know pretty quickly if the options are there. DJI MAY have changed the GUI. I don't know. So the option may still be there, but in a different location. If you've seen my videos, you know how it works on older Go App versions, so all I can say is give it a shot to see if the Go App option to roll back controller firmware still exists. If not, you will have to roll back your Go App.
And FWIW, the whole iOS/Legacy App/Legacy iTunes thing is a rabbit hole in and of itself. Your bottleneck MAY be your iOS version, as some legacy apps don't work with some modern iOS versions. And legacy iTunes DEFINITELY doesn't work with new iOS versions. So it's a whole song and dance just to get your iPad to do what you want it to do.
While I have figured out how to install legacy app versions on an iPad, I have NOT figured out how to roll back the iOS. I HAVE figured out a hack to STOP Apple from updating the iOS. But once the update has happened, there isn't much that can be done to roll it back. I save copies of my iPads to files on my Windows machine. IN THEORY I should be able to roll back to saved iOS, but have never tested that.
The previous posts regarding downgrading the iOS app using Charles \ old iTunes don’t work as the Go App is now not on the App Store.
Well...unless something has changed down at Apple, all versions should still be there. It is my understanding that Apple doesn't purge ANY software from their servers. It's just that finding it and getting to it can be difficult. To make things worse, Charles Proxy isn't an exact science. YouTuber DigDat0 has some Charles Proxy tutorials that sometimes worked and sometimes didn't for me. There are other YouTubers with CP videos that may be more up to date or "user friendly."
For us to really dig into this, we would have to know what you are trying and what your results are. CP is a Windows application, so obviously you will have to use a Windows machine to us it and get legacy app versions. If you DO decide to post your CP experience, please include screen shots. I'm no CP expert and it's been YEARS since I needed to use it. But I will do my best to help where I can.
If I use the X3 to downgrade to 1.8 assume it will be the X3 version of the firmware bin.
