no rdisk0s ... device #128

Open GoogleCodeExporter opened 8 years ago

GoogleCodeExporter commented 8 years ago 
So i start this issue with great hope we can recover any data from this 3GS.

I created the iOS5 ramdisk and my /dev/ folder has no rdisk0sXXX inside.

I attached the iPhone Update log with a try to "update" the phone the a non 
erase firmware.(Win 7 / iTunes 11.0.5)

I think the partition table is empty so the device will not show any data 
partition.

What version of the product are you using? On what operating system?
OS X version : 10.9.1
XCode version : 5.0.2
Tools revision : 9253cb99a012+ tip

Please provide any additional information below.

Is there any known way to recover the partition table or dump the complete 
flash chip content?

I work in a repair service center for smartphones. Someone take the device to 
us and said that he entered the passcode wrong to often and tried to recover 
the data with a programm. i also tried the same tool and it showed me the data 
but i can't export without buying the full version. So i tried this ramdisk 
method and ended up with this. Now the tool can't see any data anymore.

Need any more information?

weird, what was the tool ? looks like the device was wiped somehow, i don't 
think you can recover anything.

Wondershare Dr. Phone
Can i write the partition table manually?
I think the iOS has a permanent partition layout ... maybe i can create a 
partition table with this layout?

is there a way to push a tool like gparted with the needed files to the iPhone 
to scan the filesystem?

did it still boot to the lockscreen before you used the ramdisk ?
i dont think writing the partition table will help, try dumping disk0 but i 
suppose it will be all zeroes

ssh -p 2222 root@localhost "dd if=/dev/rdisk0" > dump.bin

i think this is bad ...

dd: reading `/dev/rdisk0': Invalid argument
0+0 records in

try /dev/disk0 instead of /dev/rdisk0
but i think the device was somehow erased, not sure exactly why
