CFG Lock (MSR 0xE2 write protection) This must be off, check Bios, if you can't find the option then ENABLE AppleXcpmCfgLock. Your hack will not boot with CFG-Lock enabled.
Oder sucht Euch die CFGLock.Efi unter Tools packen... im Opencore Bootmanager dann auf CFGLOCK.EFI gehen und deaktivieren
Die Anleitung ist hier zu finden:
CFG Lock
Eine weitere Alternative ist das BIOS unlocken und CFG Lock Parameter suchen und auf disable setzten...
Hier die Anleitung, Ihr solltet aber schon wissen was ihr macht, sonst geht nichts mehr...
Dell PFS Update Extractor
Description
Parses Dell PFS Update images and extracts their Firmware (e.g. SPI, BIOS/UEFI, EC, ME etc) and Utilities (e.g. Flasher etc) component sections. It supports all Dell PFS revisions and formats, including those which are originally LZMA compressed in ThinOS packages (PKG), ZLIB compressed or Intel BIOS Guard (PFAT) protected. The output comprises only final firmware components which are directly usable by end users.
Usage
You can either Drag & Drop or manually enter Dell PFS Update images(s). Optional arguments:
-h or --help : show help message and exit
-v or --version : show utility name and version
-i or --input-dir : extract from given input directory
-o or --output-dir : extract in given output directory
-e or --auto-exit : skip all user action prompts
-a or --advanced : extract signatures and metadata
-s or --structure : show PFS structure information
Compatibility
Should work at all Windows, Linux or macOS operating systems which have Python 3.10 support.
Optionally, to decompile the Intel BIOS Guard (PFAT) Scripts, you must have the following 3rd party utility at the "external" project directory:
BIOS Guard Script Tool (i.e. big_script_tool.py)
