Failed to enable JIT for {app} / The Developer disk image could not be installed

[Starli0n]

Hi,

I have the following error while trying to run JIT via AltServer.

I had installed AltStore with AltServer. At a point, JIT was working. Then I reinstall AltStore within AltStore with the IPA to be able to get ride of the Widget in order to spare an App IDs.

I had found the Disk Image for my iOS version here https://github.com/mspvirajpatel/Xcode_Developer_Disk_Images/releases/tag/15.7 but I do not know to put it...

I try to run JIT from AltStore, it does not work either.

Please note, that I am on the same Wi-Fi network, that I activated the phone connection on the same Wi-Fi, that I even tested it with a cable, and I tested to run JIT with other Apps, I have reinstall everything still the same error message...

Could you please help me ?

Any update to this or a suggestion on how to work around it? iOS 15.3 - iPhone 13 Pro Max - Same issue. Have latest Altstore 1.7.1 (81) - can't enable JIT. Read online and see some info for Windows version download JIT - But no idea where to put it on Mac. Followed the Brew commands and installed the python stuff - still no dice. I see this is from Nov 23 with no reply :(

Also trying to enable JIT via Altstore on the phone = fails with similar error "Received invalid request from AltServer".

Also Found the path I think this 15.3 dev image should be at - but it's ALREADY there ugh /Users/yourusername/Library/Application Support/com.rileytestut.AltServer/DeveloperDiskImages/iOS/15.3/

DeveloperDiskImage.dmg DeveloperDiskImage.dmg.signature

Not sure what else to try at this point though

UPDATE: Ok so I opened XCode and saw that it may not have been 'fully done setting up' or something for the first start? I said I want to develop for just MacOS - Then it worked....hopefully this helps someone else since nobody else bothered to reply. @Starli0n FYI
