DJI Go App on jailbroken iPhone

[cradle66]

Yes I did the trick with non JB mode (safe mode) and it didn't work. But I also tested dji 4 app on a jailbroken ipad pro with ios 9 and also It didn't work. I don't know what else to do but thanks to you I now use the litchi app which is a good app. As for firmware updates I use my imac and dji assistant 2 for this.
Thank you for your suggestions

Sorry
I tried again my ipad pro for a test and it works fine. What I was doing wrong it was that I tried to connect the ipad with the usb slot that is under the remote controller and not the one thats on the left. So I guess as Pp09nlk2n mentioned is the ios 8 that has the problem.
