I worked this out whilst you were finding me the answer. Noch einmal, vielen Danke!
This is the slightly different answer that I worked out:
correct format:
./payload-dumper-go payload.bin -partitions dtbo,vbmeta
- where dtbo and vbmeta are the names of the .img files you are trying to extract
- nominating an output folder with
-o name
didn’t work for me
