edk2-sdm845 Porting Guide (Obsolete)

  1. Install Python protobuf and uefi_firmware-parser by executing pip install --upgrade google-api-python-client uefi_firmware in terminal
  2. Download extract_android_ota_payload and extract the folder inside the archive anywhere
  3. Download any OTA update for your phone
  4. Extract payload.bin to extract_android_ota_payload-master folder
  5. Open terminal in the same folder and execute python3 extract_android_ota_payload.py payload.bin
  6. Execute uefi-firmware-parser -b -e xbl.img
  7. Change directory to volume-******/file-9e21fd93-9c72-4c15-8c4b-e77f1db2d792
  8. Execute 7z x -oextracted section0.guid
  9. Open UEFITool and open the file section0 in folder extracted
  10. In a file manager, open edk2-sdm845/sdm845Pkg/Binary, duplicate dipper folder and rename it to your device's codename
  11. In UEFITool, expand UEFI image and the volume underneath
  12. For each file in your device's folder replace it with UEFITool by:
    • expanding the DXE Driver in UEFITool with the same name as the file you are replacing
    • in case of file that ends with .depex right clicking on DXE dependency
    • in case of file that ends with .efi right clicking on PE32 Image
    • clicking Extract body
    • deleting the original file
    • saving the one you are extracting and naming it same as the deleted one
    • In case a part (ex. DXE Dependency) is missing in UEFITool, just delete that file
  13. Open edk2-sdm845/sdm845Pkg in a file manager
  14. Duplicate dipper.dsc and dipper.fdf and rename both to your device's codename
  15. Open the .dsc file, replace values 1080 and 2248 with your device's display width and height and save
  16. Open the .fdf file, replace every word "dipper" with your device's codename and save
  17. Open edk2-sdm845 and edit build.sh with a text editor
  18. Locate device list at the top, add your device's codename and save

You can now build as usual.

Make sure to message the Discord or Telegram group in case you are stuck somewhere and if your port is successful, send edk2-sdm845/sdm845Pkg/Binary/devicename folder and .dsc and .fdf files.
