ImgMountFailed keeps happening!

[CodeRabbid64]

I keep trying to launch DolphiniOS with JIT from my iPhone with Jitterbug, but nothing works! I used the 15.0 dev disk and it always says image mount failed. And yes I know about the faq but it has the most unhelpful answer to this question.

The devices I am using is an iPad Pro (11”) A12z (Secondary Device) & an iPhone XR (Primary Jitterbug Device)

I was getting this error from using the wrong DeveloperDIskImage.dmg and DeveloperDiskImage.dmg.signature after an update from 14.5.1 to 15.2. Try using one from https://github.com/haikieu/xcode-developer-disk-image-all-platforms/tree/master/DiskImages/iPhoneOS.platform/DeviceSupport.

Didn’t work :(

I don’t know what to do at this point.

How about launch the app directly instead of mount the image first.I think Jitterbug app has already mounted the image automatically.
