I have a 1st gen iPhone SE running iOS 10.2, and I’m trying to figure out how to open or trigger the Apple Retail Demo app / Retail Demo mode.
The device info is:
Model: 3A844J/A
Carrier: KDDI 27.1
Capacity: 16GB
iOS Version: 10.2
Modem Firmware: 5.32.00
Model Identifier: iPhone8,4
My main question is:
If this device has Apple Retail Demo / Demo App data inside, how can I open it or trigger it?
I do not want to erase, update, restore, or lose the original iOS 10.2 state.
I would like to know:
Is there any known way to launch the Retail Demo app on iOS 10.2?
Does the Demo app exist as a hidden system app, or is it only activated by a retail configuration profile?
After jailbreaking, what should I check with Filza / iFile?
Are there specific folders, bundle IDs, launch daemons, profiles, or configuration files related to Retail Demo mode?
If the Demo app is missing from the Home Screen, is there any way to make it appear again?
What should I avoid doing so I don’t destroy any possible demo-related data?
I’m not mainly asking whether this is a prototype or engineering device. I’m specifically trying to preserve the system and find out how to access the retail demo environment if it is still present.
Any help from people familiar with Apple Retail Demo units, iOS 10 demo devices, or legacy jailbreak tools would be greatly appreciated.
Thanks

Here's the photos I have (alongside the drop test)

So I have recently enrolled my MacBook Air to demo mode from demo unit and after some time the updates finally finished I did set everything up but now there’s this administrator user called “demoadmin” which has been password locked by the system?? Anyways I did try resetting the password in recovery mode but even if I do reset it I can’t use it since the login screen just stays stuck in the apple logo with the spinning beach ball the question I will be asking is what is the password/possible passwords for the user demoadmin? (I’m currently on the “demouser” user account)

Doesnt look like anything released?

sadly sep must be disabled on 5s so no touch id
