Issue Description: We are experiencing MDM profile installation failures specifically on iPhone 17 devices. After extensive testing and comparison between affected and working devices, we suspect this appears to be a parameter transmission error rather than device settings.
Technical Analysis:
- Device Settings Comparison: No differences found between problematic and
working devices in system settings, indicating this is not a configuration issue.
- Suspected Parameter Transmission Error: • Device model information appears to be restricted or blocked during profile
download • User ID and phone number parameters are not being transmitted to the server • Installation logs show missing login ID and phone number entries
Symptoms: • During MDM profile installation, the "Apps & Restrictions" section that should appear is missing • Profile download parameters are suspected to not be properly transmitted to the server • Installation process fails at the profile configuration stage
Critical Finding: When we cloned a previously working device to create a problematic device configuration, the cloned device also began experiencing the same installation failures. This strongly suggests the issue is related to device-specific parameters or identifiers.
Additional Information: We continue to receive reports of this issue from our iPhone 17 users, and these reports are occurring across various iOS versions.
Request for Assistance: Has anyone encountered similar MDM profile installation issues on iPhone 17? Are there known limitations or changes in how device parameters are transmitted during MDM enrollment on this model?
Any guidance on debugging parameter transmission or known workarounds would be greatly appreciated.
