This is specifically the Galaxy s3. Out of curiosity what are these partitions exactly. Are they part of the android OS or something lower level than that? If I were to delete everything in these partitions will I brick the phone even after a complete factory restore from "Download mode"? If these are not in fact android partitions why do some ROMs flash them? What is the difference between
/efs and are these flashed with most ROMS?
I've been googling the partition structure of my device and these things are not clear. Please help me clear them up :)
