You must have gone through the Exploring and Customizing SYS Tutorial ‘n’ Understanding and Adding new OEM/EXTApplication Packages Tutorial ‘n’ Understanding the Rom Structure, MsXipKernel and OemXipKernel, so now comes the OEM Part. OEM-Original Equipment Manufacturer is the Device Developer and Operator Specific Device Customization on top of the Base of Windows Phone OS, i.e. the SYS. Now Dumping a Stock HTC ROM of your specific Device, you’ll come across the *OEM Folder, which is the Manufacturer and Operator Specific Customization.
Now OEM on whole can be divided in 2 Parts:
-
The Manufacturer and Operator Specific Settings and Customizations
-
OEM/EXT Application Packages containing different Applications that the Manufacturer/Operator Provides in the Device
In this tutorial we will be discussing the 1st Part i.e. Manufacturer/Operator Specific Settings and Customizations.
The Included Folders are as below-
