Hi, my S3 bricked and even a JTAG could not save it. Yes, the eMMC was bricked at the very low level.
Samsung replaced my board and i checked it is now running 0xf7 revision, the sammy engineer also told me this is a safe fw immune to that superbrick. After further questioning and hardcore probing - the engineer revealed that the eMMC fw of 0xf1 has a bug in its wear leveling algorithm, which causes the sector containing the BIOS to be damaged, and this fw will fix that.
Will a dump of my firmware help you guys?
I tried a df,dmesg,lsof and other commands and could not find the mount point for the eMMC, so if you can tell me how to dump the fw, i will glady do it and hopefully it should help you.
PS: other threads on xda say samsung replaced their boards with the same defective ones; it seems that in my country, samsung actually replaces it with a newer revision.
