I mastered this puzzle/hack some time ago, which grants me unlimited access to GM Service Information for free. As much as I would like to share this trick with everyone freely like once upon a time, the times have changed and to preserve the duration of this trick I will not.
 
Anyway. This file includes information for gaining access to GM SI "Service Information" which includes GM vehicle module Pinout schematics, diagrams and other vehicle servicing information. It covers North American, European and other models. 
With this file you will gain unlimited GM SI access for eternity or until the hole gets close. 
Note: This does not support the China region. However, you can choose Korea or GMIO region instead.

This file consists of a video tutorial demonstrating how to retrieve the XML files for a module and how to remove RPO codes from the module using the GM DPS software tool.
It also includes information on manually activating and deactivating hidden menus in the IPC module using DPS.
NOTE: The video tutorial was created using the older SPS, the same as the Europe Service box SPS. The newer Techline SPS2 is the same process as the older SPS, only with a folder name change. 

GM HMI 2.5 EMMC Chip Pinouts for dumping the HMI 2.5 Emmc micro Chip
This PDF file illustrates a pin diagram that identifies the HMI 2.5 EMMC chip pins for connecting to a SD card adaptor for dumping the contents of the HMI 2.5 module's EMMC chip, which stores the Sat-Nav maps, calibration files, VIN number and other operating files.
 
Knowing the HMI EMMC pinouts has various benefits.
You can modify various files example: install your own custom boot up video for the display.
Repair a faulty HMI that has corrupted EMMC chip files.
Swap Map files.
etc.
This tutorial offers only pin-out information for the EMMC.
It does not offer nor do I offer any information or solution about any issues you may have regarding to HMI reseting or other HMI issues.
