Same here for 0xf1 (SEE THE FIX BELOW)

minealex2244@minealex2244-desktop:~/Desktop/i9300_emmc_toolbox-master$ exploit/sboot_exploit.py --shellcode shellcode/dump_fw_bootrom.bin -o 0xf1.bin
Traceback (most recent call last):

self.handle.claimInterface(self.interface)
AttributeError: 'NoneType' object has no attribute 'claimInterface'

The fix is pretty simple: just type "sudo su", enter your password and it will work.

Ok now i got the dump from the good phone (0xf7) but the checksum is 9a171aca6a556121461d09b76d3ba6da0d98e46dfb4e971ae9790fb61e4eb419

@oranav and i can't dump 0xf1 from my bad phone (sboot I9300BVBLH2) because it gives me

To be honest I'm not sure if reviving a dead S3 it's worth. You will loose EFS forever, you won't be able to recover any files but I think that it's still good as a non-daily driver. P. S. I successfully revived my S3.
Regarding your problem, did you got XXELLA sboot on your SD card?

[minealex2244]

P. S. I didn't check the MD5 sums and it worked. :))

My bad phone has the sboot partition intact, because i can boot to download mode no problem
Gonna try writing now the 0xf7 in the bad phone
EDIT: i get the same error as dumping

@theandroid02
I got the same checksum. Any Idea what version this is?

[Toomoch]

Nope i have no idea

[oranav]

@theandroid02 I'll take a look at your sboot binary and try to fine-grain the heuristics I'm using. Will update soon.
In addition, can you email me your eMMC firmware dump? You can find my contact information here

[oranav]

@theandroid02 I couldn't find the sboot you mentioned. Do you have the ROM that contains it? If not, can you dump it (sudo exploit/sboot_exploit.py --dump --output sboot.bin) and send it to me?
